TSI-1569 Release Notes Version 1.39.06, Feb 02, 2005 ============================= 1- Found and corrected 2 bugs in new password feature a) the password protection could not be turned OFF once it was turned ON due to an error in the SYS PASSWORD OFF command. b) Entering new passwords that were shorter than the previous password resulted in a mangled password consisting of the new word plus the remaining characters of the old one. c) Added ability to use backspace (rubout) while entering the password. 2- Tracked down a problem that has sporadically occurred a few times in the field. A few users reported that they would occasionally be unable to telnet into the unit, although it seemed to be operating with no other problems. Diagnosed the problem - if a user repeatedly disconnects telnet sessions while the screen is paused at a "Hit Any Key" prompt, the unit will eventually run out of process and socket resources. The problem is that the telnet session process was not being released when users disconnected while sitting at the "Hit Any Key" prompt - after this has happened many times, the unit will not be able to accept any more telnet sessions (although the serial port command line interface will work just fine). Corrected the problem so that the process and socket are properly released in this situation. Version 1.39.05, Nov 19, 2004 ============================= 1- Unit can now be password-protected for telnet connections. The password protection can be turned on and off. Serial (RS232) port access is unaffected by this change. The following new commands were added. SYS PASSWORD OFF disable password protection SYS PASSWORD check ON/OFF status of password SYS PASSWORD ON new_password define and enable new password Version 1.39.04, Mar 24, 2004 ============================= 1- Added a new TABLE entry type - Call Proceeding No Answer (CPNA). The reply to an incoming SETUP message will be a Call Proceeding message only. The call will not be taken to completion. The new command is: TABLE incoming_num CPNA num_secs Where num_secs specifies the maximum number of seconds before the call is dropped locally if the far end hasn't already released it. Typically the num_secs parameter is set to a large value. Version 1.39.03, Dec 28, 2003 ============================= 1- An optional parameter is now available for the TABLE FORWARD command. This parameter provides the ability to specify the Phone Number Type (call type) for the outgoing leg of the forwarded call. TABLE incoming_num FORWARD outgoing_num Where outgoing_phone_num_type can be: NATIONAL INTERNATIONAL SUBSCRIBER UNKNOWN If the outgoing_phone_num_type is omitted, type NATIONAL is assumed. Version 1.39.02, Oct 1, 2003 ============================ 1- The bearer capability of outbound multi-channel test calls (including BONDING ones) can now be specified as SPEECH as well as RESTRICTED, SPEECH, AUDIO3K, or AUDIO7K. Previously all multi-channel calls (BONDING or otherwise) were forced to be UNRESTRICTED. 2- Added PURGE option to the ROUTE command. ROUTE PURGE will delete all entries in the route table. After issuing ROUTE PURGE, the ROUTE LIST command will only show one record showing the local subnet address as the destination, and the 1569 IP address as the gateway. Version 1.39.01, Mar 11, 2003 ============================= 1- Changed QOV pattern. The default data value is now 7F instead of FE. The default value is transmitted before and after the specified voice clip. Version 1.38.03, Feb 20, 2003 ============================= 1- Added options to change Calling Party Presentation Indicator and Screening Indicator in the SETUP message of outgoing calls. 2- Added D-channel log support to show Presentation and Screening types. 3- Created new SYSTEM command to set the Calling Number Presentation Indicator types: SYS PHONE PRESENTATION where: ALLOWED is Presentation Allowed RESTRICTED is Presentation Restricted UNAVAILABLE is Number not available 4- Created new SYSTEM command to set the Calling Number Screening Indicator types: SYS PHONE SCREENING where: USER is User-provided, not screened PASSED is User-provided, verified and passed FAILED is User-provided, verified and failed NETWORK is Network-provided Version 1.38.01, Dec 30, 2002 ============================= 1- Added date to port 6901 hexadecimal log output and to the RAW LOG hex output. 2- Corrected a bug in the D-channel log storage. There was an anomaly in the re-use of the message buffers that occasionally caused the entire contents of the the log to be regurgitated to port 6901. 3- The SYSTEM status output was incorrectly displaying SYS SWITCH MERIDIAN as SYS SWITCH MERIDIANQSIG. 4- Added one additional status line for outgoing calls using MODE 1 BONDING. This line shows the outgoing Information Channel and indicates the number of channels requested from the far endpoint. 5- The Remote Call Forwarding feature was enhanced with two improvements: a) The outgoing forwarded call now adopts the Called Phone Type of Number (National, International, Subscriber, or Unknown) from the incoming call. b) The received B-channel from the incoming leg of the forwarded call is cut through to the outgoing call immediately after the outgoing call is initiated. This allows DTMF tones from the original call to be used for call authorization to complete the outgoing leg of the forwarded call. Previously, the B-channels in both directions were cut through only after both calls were active. 6- When SYS BOND PREFIX was OFF, the port 6905 BOND status messages were becoming scrambled. Version 1.37.03, Oct 25, 2002 ============================= 1- Remote Call Forwarding added. Any incoming call that matches a Phone Table FORWARD entry type will be forwarded to the specified destination. The new command is: TABLE in_phone_number FORWARD out_phone_number Any incoming call to the 1569 with in_phone_number as the destination will cause the 1569 to place an outgoing call to out_phone_number. After successful completion of the outgoing call, the incoming and outgoing calls will be connected together. When either call disconnects, the 1569 will disconnect the other call as well. Version 1.37.01, Sep 20, 2002 ============================= 1- Added round trip delay as a test pattern selection. Calling a loopback using this test pattern will show the round trip delay in milliseconds. Version 1.36.04, Sep 16, 2002 ============================= 1 - Added support for transmitting and capturing voice clips to aid in QOV testing. 2 - Added SENDSNAP command. 3 - Send FE's (zero) after sound clip transmission has completed. Version 1.35.02, Mar 12, 2002 ============================= 1- Added this new command to disable SNMP functionality: SYS SNMP OFF All SNMP access will be disabled and no SNMP traps will be transmitted. The previously normal mode of operation can be restored by using: SYS SNMP ON Version 1.35.01, Jan 11, 2002 ============================= 1- Corrected an error in the SNAP and SNAPCLIP functions. The SNAP was incorrectly capturing outgoing bytes being transmitted by the SENDCLIP function if the same channel was being used. Version 1.35.00, Dec 6, 2001 ============================ 1- The D-channel was not operating correctly at times when the unit powered up in Cross Connect mode. The D-channel would stop transmitting. The problem was isolated and corrected. Version 1.34.05, Nov 14, 2001 ============================= 1- Enhancements were made to the Mode 1 BONDING capability. The unit will now more carefully detect a mismatch in the number of channels or the bearer rate during master channel negotiation. Detecting a mismatch or that the far end is not Mode 1 will result in call termination before the unit attempts to retrieve additional numbers from the far end. New error messages were added to more clearly indicate a mismatch. Version 1.34.04, Aug 2, 2001 ============================ 1- Bit error test records that are broadcast from Port 6904 were sometimes indicating a call reference value of 0. This was occurring sometimes in the last record for a test - the record that indicates the test has been stopped. This was only happening with tests configured with a specific duration, not with continuous tests that were being stopped with the TEST STOP command. The problem was that the call reference value was being cleared to zero before the bit error record was send from Port 6904. This has now been corrected. Version 1.34.03, Jul 6, 2001 ============================ 1- B-channels were being left in an incorrect state after any outgoing BOND test call that used the TEST ECHO ON (to disable echo cancellers) option. Susequent BOND calls using the same channels would fail to connect properly. The problem was isolated and corrected. Version 1.34.02, Jul 5, 2001 ============================ 1- BONDING calls using Channel 16 as the starting channel were not connecting. This problem was isolated and corrected. 2- Some of the BONDING messages broadcast from Port 6905 had misleading timestamps. The stamps represented when the line of information was started instead of when the line was completed. Sometimes this was off by up to 10 seconds. The timestamp headers now represent the time that the line of text was completed. 3- The unit now coexists with IP subnet zero addresses. 4- A few changes were made for THROUGH mode. The Layer 2 message counters are now functional. Additional Layer 3 message counters are now functional - some were missing before. Maintenance messages with a protocol descriminator of 03 or 43 hex now pass correctly through the unit. SERVICE and SERVICE ACK messages fit into this category. 5- A new command was added. "DUMP START" now shows a saved version of the initial sequence of powerup messages that are normally viewed via the RS232 serial port. This allows a telnet user to see any startup errors. Version 1.34.01, Mar 21, 2001 ============================= 1- TEST RESTART was triggering a Port 6904 record before the RESTART was actually completed. This was resulting in a record that showed the state of the test before the RESTART. The Port 6904 test record will now show the results of the test after the RESTART has been completed - all bit errors will be cleared and the elapsed seconds will be zero. Version 1.34.00, Mar 19, 2001 ============================= 1- A new feature was added that can be accessed with a Telnet client. TCP Port 6904 now provides bit error test information as it occurs. A record is broadcast to all 6904 clients when each test starts, stops, or a bit error has occurred. A typical record might be: [14:55:50:000 0 15 0001] 1 1 0 Y Y 3 The components of the record are (from right to left): a) Time of day timestamp in hours, minutes, seconds, and milliseconds. b) Interface number that the test is running on. c) Channel number that the test is running on (the first channel number if the test is running on multiple channels). d) The Call Reference Value (Q.931) of the call (or the call containing the first channel if the test is running on multiple channels from multiple calls. e) The total number of bit errors for the test. f) The total number of bit errored seconds for the test. g) The total number of bit severely errored seconds for the test. h) 'Y' or 'N' to indicate whether the test is 'In Progress'. This field will be a 'Y' if the test is running. i) 'Y' or 'N' to indicate whether the test is 'In Sync' or was 'In Sync' before the test stopped. j) The number of seconds that have elapsed since the 'In Sync' status was first achieved. The number of bit errors divided by the elapsed seconds will give the bit error rate. 2- Another new feature was added that can be accessed with a Telnet client. TCP Port 6905 now provides status messages showing the progress of an incoming BONDING call. These messages will be broadcast to all 6905 clients. The messages are very similar to the status messages now shown on an outbound BONDING call. Version 1.33.01, Feb 20, 2001 ============================= 1- Added SNAP command that allows a 'snapshot' of all the data on a particular channel to be captured and displayed. The syntax of the command (see HELP DIAG) is: SNAP intf_num chan_num num_secs Where num_secs is the number of seconds of data to capture. Version 1.33.00, Dec 12, 2000 ============================= 1- The D-channel was being left in a non-operational state any time the System Mode was switched from MONITOR to TEST mode. This problem was isolated and corrected. The HDLC controller used for D-channel communications was not operating in the correct mode although the registers were being correctly reconfigured after the mode change. Version 1.32.03, Nov 2, 2000 ============================ 1- Some units were encountering an occasional problem reading their non-volatile memory chip. The next read would be successful, but some false Events were being recorded in the Event Log. The most common symptoms were Events such as "Processor A OK" and Mode Changes that never really occurred. This problem was fixed by adjusting the configuration of the chip select that is used to access the non-volatile memory. 2- A subset of the units that had problems accessing the non-volatile RAM also were experiencing a worse symptom. The same RAM chip would occasionally reset the D-channel HDLC controller, causing loss of D-channel communication capability. The only solution when this happened was to reboot the unit. This problem was also fixed and should never occur again. 3- The Layer 3 message counters (accessed via the L3 or LAYER3 command) were expanded to 4-byte counters. The counts will no longer 'wrap' back to 0 after 65535 messages. 4- The call reference value used for outgoing test calls would erroneously wrap back to 0 (an invalid value) after 4096 outgoing test calls. This was corrected. Version 1.32.00, Aug 31, 2000 ============================= 1- The QSIG and NI2000 switch types were added. 2- The Calling Name function is supported for the NI2000 switch type. The Calling Name will be sent in a FACILITY message following the SETUP message that contains a FACILITY IE that specifies 'information following'. The Calling Name itself can be specified using the new SYS NAME command. 3- Fixed problem when using NT 'switch simulation' so that a CALL PROCEEDING message will always be sent in response to a incoming SETUP message. The CALL PROCEEDING was not being sent in response to a SETUP message that triggered a HANDSET table entry. Version 1.31.02, Aug 11, 2000 ============================= 1- The RESTART command is now being properly propagated from the Master to the Slave units. 2- The D-channel HDLC buffers were getting 'confused' sometimes when a loss-of-frame condition occurred repeatedly on the PRI interface or the DXC interface in the case of THROUGH or MONITOR mode operation. Safeguards were put in place, and the buffer mechanism is completely restarted when correct framing is detected on the PRI (and/or DXC). Version 1.31.01, Jul 11, 2000 ============================= 1- Due to fix to the SEND RAW problem in the last release, commands such as PROMPT were resulting in a trailing space being appended to the command argument. The OV command would not work properly either. This has been fixed. 2- Calls originated using TEST DTMF were timing out prematurely. This has been corrected. Version 1.31.00, Jul 7, 2000 ============================ 1- If a PROGRESS message with a Progress Indicator of "In-Band Information Available" is received during call setup, the call will not be disconnected. Previously, the 1569 would send DISCONNECT because it assumed that the in-band message was announcing that the call could not be completed. This change applies to both the 1569 and 2069. 2- Made some adjustments to when the TEST DTMF digits are transmitted. Previously, the digitized DTMF tones were transmitted after the 1569 received either an ALERTING or PROGRESS message. However, some configurations need the digits transmitted after the call is ACTIVE. A change was made to send the digits either 2 seconds after receiving either a PROGRESS or ALERTING message, or 200 milliseconds after the receiving a CONNECT message if the CONNECT closely follows the PROGRESS or ALERTING message. This change applies to both the 1569 and 2069. Version 1.30.03, Apr 27, 2000 ============================= 1- Increased the number of phone number digits allowed in SYS PHONE, TEST PHONE, and TABLE entries to 30. Increased the number of digits accepted in incoming calls to 30 as well. The D-channel log will show up to 30 phone number digits for Called and Calling Party numbers. Version 1.30.02, Apr 13, 2000 ============================= 1- Diagnosed a occasional problem that occurs with the DOWNLOADCODE TCP/IP telnet download feature. Accidentally typing a character after the DOWNLOADCODE command and before the hex file transmission starts was sometimes causing the checksum to be drastically wrong even though the code was successfully downloaded and installed. This will not cause a problem any more. 2- Some diagnostic information was added concerning telnet downloads. Version 1.30.01, Mar 17, 2000 ============================= 1- Added MONITOR mode. In this mode, the PRI (Switch) Rx D-channel is logged as the NT in the D-channel log, and the DXC Rx is logged as the TE. The 1569 serves as a two channel protocol analyzer. No messages are transmitted. The input level is assumed to be DSX (cross connect) levels. However, monitor level signals can be used. In this case, issue the SYS RXLEVEL MONITOR command. To revert back to cross connect levels, issue the SYS RXLEVEL NORMAL command. The current RXLEVEL setting can be obtained by using the SYS RXLEVEL query. 2- Corrected a serious problem that sometimes occurs when receiving lots of D-channel traffic (such as from a call generator) and when more than one interface is in use (one or more Slave units). When this problem occurs, both D-channel and Slave communications are lost, and the unit must be rebooted to restore communications. This problem has been isolated and corrected. 3- The 1569 now keeps track of which channels are considered 'Out of Service' by the switch. These channels are marked with an 'x' in the channel map (MAP command). 4- When outgoing calls (originated using the TEST START command) fail, the cause value from the Switch (or remote end) is now displayed in decoded text format. 5- The CHANGE STATUS info element in SERVICE and SERVICE ACK messages is now decoded into text showing the new status. Version 1.29.03, Nov 9, 1999 ============================ 1- In the OVERVIEW and CALLS status displays, test numbers larger than 99 were being truncated to 2 digits. This only occurred when placing a test call with an Interface Number greater than 3. This has been corrected. Version 1.29.02, Nov 3, 1999 ============================ 1- The 1569 will no longer send a DISCONNECT in response to a PROGRESS message with a PROGRESS INDICATOR of "In-band information available" if SYS SWITCH is set to DMS. Version 1.29.01, Nov 2, 1999 ============================ 1- Added the ability to remap a slave interface to temporarily become a different interface number. For instance, Slave Interface 1 can be remapped so that it appears to be Slave Interface 5. Notice that this is a very unusual thing to do and will only be useful for some special situations. A new command was added to accomplish this: SYS REMAP INTERFACE x y x = the current interface number y = the remapped interface number Both the current and new remapped interface numbers must be be less than the value of SYS NUM CARDS and greater than zero (Interface 0 can never be remapped). If there is just a Master and a Slave interface (Interface 1), then SYS NUM CARDS will have to be increased before a remap can be accomplished. This will cause Slave Interface alarms to occur for the cards that are not physically present. These alarms can be suppressed or enabled via a new command: ALARMS INTERFACE ON = allow alarms (power-up default) OFF = suppress alarms of missing slaves To check on the status of all the interfaces, another new command was added: INTERFACES shows the status of all interfaces 2- Ethernet downloads will be even faster now. Characters will not be echoed while downloading. This reduces the Ethernet traffic and speeds up the process. Version 1.28.02, Sep 14, 1999 ============================= 1- Corrected some small errors in Ethernet download enhancement. 2- Corrected situation in which a small portion of the bootstrap code was being overwritten during the power-up memory test. No known problems have occurred because of the overwriting. Version 1.28.01, Aug 17, 1999 ============================= 1- Added the capability to load future software upgrades via a Telnet session over the ethernet connection. However, Version 1.28.01 must be loaded via the RS232 like the previous versions. All future releases can then optionally be downloaded via TCP/IP, once Version 1.28.01 or higher has been installed once via the RS232 command port. A new command, 'DOWNLOADCODE', is provided for initiating an TCP/IP software update session over the Ethernet connection. Once the command has been issued, the unit will wait for the new software file to be sent. The file containing the new software should be sent in text (ASCII) form, without using any protocols such as Xmodem or Zmodem. HyperTerminal can be used to perform the download in a telnet session. Open the telnet session, issue the 'DOWNLOADCODE' command, and send the hex file using the 'SEND TEXT FILE'. However, your version of HyperTerminal must support TCP/IP telnet connections. Some of the older versions do not. Higraeve, Inc. offers a low-cost upgrade to HyperTerminal at www.hilgraeve.com/htpe.html that will support TCP/IP telnet sessions. Hilgraeve supplied the versions of HyperTerminal that ships with Windows 95, Windows 98 and Windows NT. Version 1.27.02, Aug 3, 1999 ============================ 1- Additional corrections to prevent loss of ethernet communications. Consecutive collisions on busy networks was causing ethernet transmitter to shut down. The real time clock was occasionally causing unnecessarily frequent retransmits. 2- Eliminated some false 'Rx DSP Fail' messages that were being inserted into the EVENT log. Eliminated the corresponding SNMP trap messages. Version 1.26.03, July 2, 1999 ============================= 1- Setting SYSTEM TELNETIDLE 0 will disable the timeout for an idle telnet user. 2- Drop outbound call if Progress Indicator with "In band information available" is received after sending SETUP. 3- Added PING utility (see HELP DIAGNOSTIC) for troubleshooting IP connections. 4- The Progress Indicator information element is now more fully decoded in the D-channel log. Version 1.26.02, June 24, 1999 ============================== 1- Corrected a serious problem in the ethernet handler. Under some situations, heavy receive activity was causing a loss of ethernet communications. In some of these occurrences, serial port communications may have been lost as well. 2- Added the capability to monitor the alarm and general status of the 1569 using a Telnet client to access Port 6903 at the same IP address as the regular Telnet command port. A Telnet client opened to this port will see all postings to the 1569 Event log, which includes all SNMP traps that the 1569 will send. The 1569 will support multiple Telnet sessions to Port 6903 at the same time, without interferring with the regular command port. In addition, Port 6901 can be accessed to show D-channel activity (in raw hexidecimal form), and Port 6902 shows entries in the CALLS LOG as they are added in real time. All of these ports can be active simultaneously. Version 1.26.01, June 9, 1999 ============================= 1- Added support for Codeset 5 DISPLAY TEXT information element in the D-channel log display. Version 1.26.00, June 3, 1999 ============================= 1- Added decoding of MORE DATA and SENDING COMPLETE info elements in the D-channel log display. 2- Eliminated some unnecessary SNMP MIB definitions in the tsi1569.my file. 3- Was getting a double prompt when using the serial port. This was not a problem with a Telnet session. Version 1.25.00, May 06, 1999 ============================= 1- Made changes to support BONDING with Adtran ISU 512. Modified the delay equalization calculation to correct an error. 2- Corrected problem with BONDING calls when Interface 1 unit is the MASTER in a Backup D-channel configuration. Information was not being transferred correctly to the BACKUP unit when the MASTER was Interface 1. 3- There was an error in the TABLE definition for TABLE TEST_CALLBACK. If no template was specified (meaning none to be used), the template from the previous TABLE TEST_CALLBACK or TABLE CALLBACK was being used. This will not happen now. 4- Users accessing the unit with the Graphical User Interface (GUI) will not lock out other telnet users indefinitely any more. The GUI will not cause the TelnetIdle counter to reset, so that another user can obtain control after TelnetIdle expires. The default value for SYS TELNETIDLE is 600 seconds (5 minutes). 5- The default value for SYS NEGOTIATE is now OFF. If the switch supplying the PRI to the 1569 supports B-channel negotiation, SYS NEGOTIATE should be turned ON. 6- The TEST results (either TEST test_num or OVERVIEW) will not show IN SYNC now if the test pattern is Pattern 1 (LOOP). Running a test with a Loop as the transmitted pattern is not really a test, and IN SYNC was misleading. 7- SETUP ACK messages will now be accepted, but no action will be taken. 8- In previous versions, if powerfail occurred while the unit was powering up, the unit could be left in a state so that it would stay in the download mode (show the "DNLD>" prompt) on the next powerup cycle. This has been corrected. 9- The pattern of a currently running test can be changed using the "TEST PATTERN pattern_num test_num" command. Some bit errors will occur and pattern sync will be lost during the pattern change. Use TEST RESTART to clear the test results. Version 1.24.00, Feb 03, 1999 ============================= 1- Added error message when user tries to modify Phone Table in a BACKUP unit. Version 1.23.00, Jan 28, 1999 ============================= 1- Enhanced the list of cause values that are explained in LOG printouts and shown in the CAUSE command. 2- TABLE command is now view-only for units that are in the BACKUP state. This applies to configurations with Backup D-channels only. 3- TEST PHONE and SYS PHONE commands now check the entered phone number and require that only numeric digits be entered. 4- Added new CONFIG command that will print out all settable configuration parameters (SYS, FRAME, CODE, TABLE ) in a form that can be entered back into the unit. This allows a system configuration to be captured using a host. This configuration file can be loaded into a unit running the same version of software without any editing. 5- Commands that start with '#', ';', or '/' are now ignored. The CONFIG command uses these characters to insert comments into the output file for information that is useful (date, software version, unit name, unit prompt) but does not need to be loaded into a unit. 6- Added SN command that is the same as the SYS command, except that the SYS status screen is not shown. CONFIG uses this variation of the SYS command in its output. 7- The user is now prevented from turning SYS BACKUP OFF on Interface 0 when BACKUP is ON and Interface 1 is an active MASTER. Version 1.22.00, Nov 05, 1998 ============================= 1- Incoming calls to TABLE NEGOTIATE or TABLE BOND (if SYS NEGOTIATE was ON) entries were not being answered correctly in most cases. The Channel Id information element in the CONNECT reply message was incorrect in most cases. Version 1.21.00, Oct 28, 1998 ============================= 1- Changes for Backup D-channel. a) A BACKUP unit will now send a Layer 2 DISC in response to any Layer 3 message except RESTART or SERVICE IN DCHANNEL. This is for the purpose of preventing deadlock situations in which the switch assumes a D-channel is active when the 1569 does not. b) When a BACKUP unit is waiting for the SERVICE IN DCHANNEL message it will not reply to any Layer 3 message. However, to acommodate the DMS-100 and DMS-250, the BACKUP unit will reply to a Layer 3 RESTART message with a RESTART ACK. c) One problem was found with BACKUP units not saving new configuration information received from the MASTER unit into the motherboard EEPROM storage location. This problem was isolated and corrected. 2- The D-channel log has been enhanced. It now saves longer messages and stores more messages than before. Previously, messages longer than 90 bytes were truncated when stored. Now, the entire message is saved. Also, up to 2000 messages are saved now, compared to 1000 previously. 3- Added the following new System configurations for setting the value of Layer 2 and Layer 3 parameters. Added: SYS N201 n (sets max Layer 2 message size) Added: SYS T301 n (value of Layer 3 timer T301) Added: SYS T303 n (value of Layer 3 timer T303) Added: SYS T305 n (value of Layer 3 timer T305) Added: SYS T308 n (value of Layer 3 timer T308) Added: SYS T310 n (value of Layer 3 timer T310) Added: SYS T313 n (value of Layer 3 timer T313) 4- Many enhancments for UUI and Codeset 7 processing and testing were added. UUI and Codeset 7 elements can be included in the SETUP messages for originated test calls now. UUI and Codeset 7 elements can be sent in response to incming SETUP messages that have Called Party Numbers that match the TABLE UUI_xxxx entries. Added: TEST UUI (sends UUI in SETUP message) Added: TEST CODE7 (sends Codeset 7 in SETUP) Added: SYS FAC_CA_TSC (how unit responds to FACILITY) Changed: DISCONNECT (added the UUI option) Changed: TABLE UUI_ALERTING (added option) Changed: TABLE UUI_CONNECT (added option) Changed: TABLE UUI_ALERT_CONNECT (added option) Changed: TABLE UUI_DISC (added option) Changed: TABLE UUI_RNA (added option) 5- The UUI and Bridge commands were added to the HELP screens. These commands were previously only described in an auxiliary document. This document is still a more complete source of information for the UUI and Bridge capabilities, and is available from TELESYNC. 6- Any command followed by the letter 'T' was causing a system lockup. This was due to an internal list of possible argument matches that overflowed due to the large number of command arguments that start with the letter 'T'. The problem was corrected. Version 1.20.00, Aug 10, 1998 ============================= 1- Added ability to generate TEST calls while in Cross Connect mode. Bit Error Rate tests can now be initiated and monitored while in Cross Connect mode, using the TEST commands. Only Handset calls, Frame Relay tests, and a few test patterns are not permitted now in Cross Connect mode. 2- In Cross Connect mode, calls can now be generated using the TEST menu to connnect one or more channels from the DXC interface to the destination. A new pattern (X-Connect) has been added to provide this new capability. Multiple channel calls can generated using DXC channels, either as one multi-channel call, or as a series of calls using Mode 1 BONDING. The TSI-1569 now can be used as an Inverse MUX for the DXC interface device. Version 1.19.00, Jul 16, 1998 ============================= 1- Added 2804 Hz tone. Version 1.18.00, Jul 02, 1998 ============================= 1- The DTR output pin on the RS232 DB9 connector will now be at +9 volts. The output level was -9 volts previously. Version 1.17.00, Jun 29, 1998 ============================= 1- When using SYS SWITCH NI-2, the Channel Id element in outgoing SETUP messages will use implicit identification of the interface number, if only one interface is controlled by the D-channel. In this case, Octet 3.1 will NOT be included to explicitly identify the interface number as Interface 0. Version 1.16.00, Jun 19, 1998 ============================= 1- Initial command prompt was missing after power-up. 2- Test results were scrolling off the top of 25 line screens (when using the TEST xx command even if SYSTEM PAGED was ON. Version 1.15.00, Jun 05, 1998 ============================= 1- L1 (LAYER1) command was not reporting PRI AIS and PRI YELLOW alarms correctly. The values reported were actually the DXC AIS and DXC YELLOW states. 2- When receiving a LOS or LOF ALARM on the PRI interface, AIS will be transmitted at the DXC interface. 3- When receiving a LOS or LOF ALARM on the DXC interface, AIS will be transmitted at the PRI interface, when in CROSS_CONNECT or THROUGH mode. Version 1.14.00, May 29, 1998 ============================= 1- Corrected problem with echo canceller disable tone generation when used as option in TEST command. Tone was never being generated and pattern was being left as ONES regardless of requested TEST PATTERN. 2- Added new switch types: 4ESS, 5ESS (replaces old ATT type), NI2, and ETSI. 3- Added MODEL command. Returns "1569" to identify the product model number. Version 1.13.00, May 26, 1998 ============================= 1- Fixed problem for incoming NEGOTIATE calls while in CROSS CONNECT mode. Calls were being granted loopbacks instead of being connected to the corresponding channel on the DXC interface. Version 1.12.00, May 12, 1998 ============================= 1- Change to Master/Slave bus clock rate. Version 1.11.00, May 07, 1998 ============================= 1- Minor changes to the Telnet software. 2- SEND DISC will not reduce a MASTER to BACKUP if D-chan backup is ON. 3- Added check: if D-channel backup has been turned off, Interface 0 becomes a Master and all other interfaces become Slaves. Version 1.08.00, Apr 29, 1998 ============================= 1- A problem was identified that occurred when Slave (or Backup) cards were given System parameters from the Master that did not agree with the parameters stored in the EEPROM on the chassis motherboard. These new parameters were not being stored in the EEPROM for the next reboot. This problem has been corrected. Version 1.07.00, Apr 07, 1998 ============================= 1- Added a new feature to facilitate Year 2000 compliance. The new SYS YEAR <2,4> command can be used to configure the 1569 to display either a 2-digit or a 4-digit year when showing the system date in response to the DATE command. The year will still be 2 digits in log printouts. The DATE command will now accept either a 2-digit or 4-digit year when setting the date, regardless of how the SYS YEAR is set. 2- Added SYS NUM CARDS command. SYS NUM CARDS specifies the number of TSI-1569 cards installed in one chassis group. SYS NUM INTERFACES specifies the number of T1/PRI interfaces controlled by the D-channel of the Master card in one chassis group. The number of interfaces can be larger than the number of cards, but not vice-versa. This arrangement allows a Master TSI-1569 to process calls for a D-channel that controls more interfaces than are physically connected to individual TSI-1569 cards. If SYS NUM INTERFACES = 2 and SYS NUM CARDS = 1, the Master TSI-1569 will accept calls for both interfaces. Since there is no card to monitor the second interface, no alarms or traps will be generated for the second interface. No alarm will be generated because of the lack of a second card being connected to the Master. No bit-error tests can be executed on channels that belong to the second interface. Version 1.06.21, Mar 31, 1998 ============================= 1- The IP Route table was not being saved on the chassis motherboard unless the IP address or IP mask were changed as well. Now, the IP Routes will be correctly saved as they are added. Version 1.06.20, Mar 9, 1998 ============================ 1- The TABLE CALLBACK and TABLE TEST_CALLBACK functions were enhanced. An additional parameter was added to both TABLE entry types. The new parameter is a template used to create the new Called Party (destination) phone number that will be the target of the callback. Previously, the callback was generated to the Calling Party Number received on the original call to the 1567. However, the new template allows the Calling Party number to be modified before it becomes the destination number for the callback. For example: TEST 3391001 CALLBACK 1XXXXXXXXXX The X's indicate digits to be taken from the incoming Calling Party Num. Any other digits (like the '1') indicate digits to be inserted in specific position in the new Called Party Number that will be dialed. In this example an incoming call to 3391001 is received from 4046297745, and a loopback will be given. When the call disconnects, a new outgoing call will be launched to 14046297745. 2- The IP Route table is now saved on the chassis backplane motherboard, and therefore is saved on a per-slot basis. Previously the routes were saved on the individual TSI-1569 cards. Now the IP address, IP mask, and IP Routes are all saved on the chassis motherboard. 3- The MIB file (tsi1569.my) was edited to remove unused and outdated definitions. Version 1.06.19, Feb 9, 1998 ============================ 1- Corrected Pattern description on incoming BONDING calls to show "X-connect" in pattern field when connection through unit becomes transparent and data from DXC is being passed along to PRI interface. Version 1.06.18, Dec 19, 1997 ============================= 1- Added support for monitor mode relay. 2- Ethernet now autoselects the AUI (10Base2) or TP (10BaseT) interfaces. Version 1.06.16, Nov 17, 1997 ============================= 1- Incoming BONDING calls to Interface 1 when SYS NEGOT ON option was used were not being connected correctly. Calls to Interface 0 were completing with no problems. Problem corrected. 2- SYS NEGOT now defaults to ON as a factory default. Version 1.06.15, Nov 14, 1997 ============================= 1- One less space between time and date in D channel log. 2- Interface number now sent with hardware-related traps. The interface number was already being sent with the T1 alarm traps. 3- The MIB file (tsi1569.my) has been updated. Version 1.06.14, Nov 4, 1997 ============================ 1- Added Date to D channel log report. 2- Corrected problem with incoming calls to a TABLE TEST phone number. The tests were being terminated early if the test duration was longer than 60 seconds. 3- Changing the number of channels to one using the TEST command will now automatically disable BONDING. Version 1.06.13, Oct 24, 1997 ============================= 1- More improvements for multiple simultaneous incoming BONDING calls. 2- Fixed a very occasional problem with long timeouts on outgoing BONDING calls. 3- Default value for SYS NUM DCHAN command is now 100. Version 1.06.11, Oct 14, 1997 ============================= 1- Increased ability to support multiple simultaneous incoming BONDING calls. 2- Fixed problem with "TABLE xxxx CROSS 0, n" type calls that was created in Version 1.06.09. 3- Enhanced Event log reporting. 4- Added ability to perform LMI Frame Relay tests on outbound BONDING calls. 5- Attempt fix problem with incoming BONDING call from Adtran ISU. Adtran skips last two steps of "handshaking on all channels". Does not set RI=1, and A=0. Version 1.06.09, Oct 10, 1997 ============================= 1- Incoming BONDING calls can now use cross connecting to align the incoming channels with the T1 DXC channels if channel negotiation is not available. If channel negotiation is not available, issue the following command: SYS NEGOTIATE OFF 2- Corrected the frequency & amplitude calculation. 3- Added new Event log to assist in troubleshooting. Information about traps that are sent (including T1 alarms), rejected calls, and other important events are recorded in the log. The EVENT command will call up the log. 4- Added option to limit the number of D channel log message that are dumped when a Telnet session is connected to port 6901. The new commmand is: SYS NUMBER DCHAN n (n = 0-1000) To view the current setting, just type: SYS NUMBER DCHAN 5- A new table entry type -- BONDLOOP -- was added. This entry type is for use in TEST mode. The BONDLOOP command replaces the BMAST/BADD form of defining incoming BONDING calls. The same phone number will be used for the first (master) and additional calls. The format of the command is: TABLE phone_num BONDLOOP Version 1.06.08, Sep 26, 1997 ============================= 1- Fixed problem with outgoing BONDING call not retrieving phone numbers from destination correctly. Version 1.06.07, Sep 24, 1997 ============================= 1- Modified LED command to show Mode as TEST, THRU, CROSS. 2- Fixed bug in LOG RAW command. Was not properly showing log after power-up until regular LOG command was issued. 3- Added support for Master Override switch (Position 4 on S1) on card. If S1, Position 4 is ON, card becomes a Master regardless of chassis position or chassis number. Following settings will be configured: Number of Interfaces = 1 Interface Number = 0 Backup D-channel = OFF 4- LBO command will now show the LBO settings on Slave units. Version 1.06.06, Sep 15, 1997 ============================= 1- Some enhancements were made to increase performance while BONDING numerous channels. 2- The PATTERN command is now available while in the CROSS CONNECT mode of operation. 3- A STATUS message (with Cause = Mandatory Element Missing) will be sent in response to a received PROGRESS message with no Progress Indicator information element. 4- Eliminated spurious entries in the Test Log that were being generated by RESTART messages for single channels when no call was active on the indicated channel. Version 1.06.05, Aug 19, 1997 ============================= 1- Minor changes to HELP screen (HELP CONFIG screen). Version 1.06.04, Aug 14, 1997 ============================= 1- Fixed LOG RESTART (or LOG PURGE). Was not always clearing log correctly. 2- Modifications to Ethernet handler. Version 1.06.03, Aug 12, 1997 ============================= 1- Added NSF for UUI to Facility Reject messages triggered by the TABLE FAC_REJ and SEND FAC_REJ commands. 2- Corrected some errors in the Congestion control RR and RNR messages, including the call reference value. Increased the maximum value of SYS CONGESTION to 65535 from 9999. 3- Added two new send commands to assist in UUI testing. SEND CONGESTION RR SEND CONGESTION RNR 4- Fixed problem with BONDING. Was not originating BONDING calls properly when channel 1 was used. 5- New Call/Test activity log is introduced that shows the results of all in/out calls that have been disconnected. 6- Ability to 'broadcast' new Call/Test log to multiple Telnet sessions is introduced (telnet to port 6902). Version 1.05.14, Jul 31, 1997 ============================= 1- Change for calls initiated using EXECUTE RAW commands. The corresponding test will now be killed after the specified duration of the call, not the duration of the test after pattern sync is achieved. Version 1.05.13, Jul 29, 1997 ============================= 1- D-channel backup enhancement. All information about active calls is now transferred from Master to Backup unit, so that even all test info is now transferred. Active tests will be resumed on the Backup unit. If the failed D-channel unit is capable, ongoing bit error rate tests from that interface will be continued, although some bit errors and possibly a temporary sync loss will result. 2- Changed some SNMP hardware traps from Minor to Major in Severity. 3- Enhancement to support Meridian 81 PBX. Added new switch type. SYS SWITCH MERIDIAN will configure the unit for the PBX. When the unit is operating in the MERIDIAN mode, SETUP messages will have a slightly different Channel Id info element. The channel number (Octet 3.3) will NOT have Bit 8 set to a 1. Version 1.05.12, Jul 25, 1997 ============================= 1- Change for D-channel Backup. Master unit becomes a Backup unit properly now after a loss of signal or framing on the PRI. Version 1.05.11, Jul 23, 1997 ============================= 1- Change for Siemens Backup D-channel. Try to keep up all active calls when changeover from one D-channel to the other D-channel occurs. 2- Corrected a problem with displaying the Called Number using the OVERVIEW and CALLS command after a D-channel changeover occurs. The Called Number is not available after a changeover. Instead of being erroneously shown as "(incoming)", it will be shown as "(outgoing)". 3- Changed angle brackes used in "" and "" in CALLS and OVERVIEW Called Number fields to parentheses as in "(incoming)" and "(outgoing)". This was done to prevent confusion with host software that looks for the ">" to indicate the command prompt. Version 1.05.09, Jul 21, 1997 ============================= 1- Change for Siemens Custom PRI for Service and Service Ack messages. Service and Service Ack messages are now sent with Protocol Descriminator of 43 (hex) instead of 03 (hex) if the SYSTEM SWITCH SIEMENS option is in effect. Version 1.05.08, Jul 21, 1997 ============================= 1- Minor changes to D-channel log broadcast. Version 1.05.07, Jul 16, 1997 ============================= 1- D-channel log broadcast over IP port 6901 implemented for multiple connections. 2- Corrected Help entry for LBO to show 5 values are now supported. The LBO value can be from 1 to 5. The corresponding distances for the value entered are: 1 = 133 feet 2 = 266 feet 3 = 399 feet 4 = 533 feet 5 = 655 feet Version 1.05.06, Jul 13, 1997 ============================= 1- Internal company beta test. Version 1.05.05, July 10, 1997 1- Fixed problem encountered when receiving Layer 3 messages that contained locking shifts to codesets other than Codeset 6 or Codeset 7. 2- Enhanced SEND RAW command. Can send SETUP or any other Layer 3 message now. The user-specified call reference value in the message will be substituted for in SETUP messages but will be passed without modification in other messages (like a DISCONNECT message with a call reference that matches an existing call). Any calls that become active as a result of a SETUP message sent using the SEND RAW command will now show up in the status displays invoked using the CALLS command or OVERVIEW command. This is an enhancement. 3- Added AUDIO3K and AUDIO7K to the HELP TEST screen. These parameters were available for the TEST CAPABILITY command, but were omitted from the help screen. Version 1.05.04, Jun 27, 1997 ============================= 1- SF framing now works. The SF framing choice was available but was not working correctly.
