TSI-1575 Release Notes Version 1.08.00 Feb 02, 2005 ============================= 1- Found and corrected a bug in the password feature. 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. 2- Added ability to use backspace (rubout) while entering the password. 3- Tracked down a problem that has sporadically occurred 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 1.07.10 Sep 29, 2003 ============================= 1- 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 1575 IP address as the gateway. Version 1.07.08 Dec 27, 2000 ============================= 1- Corrected a major problem with the DSP modems and their interaction with the Controller processors. Due a recent change in the DSP firmware, one of the DSP code overlays was being incorrectly handled. The result of this was loss of communication with the DSP modems and the indication of this was the Modem Alarms. This release should be loaded as soon as possible because of the severity of the problem. 2- Outgoing test calls were not functioning correctly. Corrected some problems including the fact that the test duration was not being obeyed. Also added a cause value announcement for outgoing calls that fail to connect at all. 3- Outgoing calls were being dropped when a PROGRESS message with a Progress Indicator of "In Band Information Available" was received from the far end. However, sometimes the far end intended to accept the call, even though a voice message was being played. Now, these calls will be taken to completion unless the far end includes a Cause Information Element in the PROGRESS message, which would indicate a failed call. 4- The RELOAD MODEM and RELOAD CHANNEL diagnostic commands were removed. They were originally used for debugging and were no longer functional. Version 1.07.06 Nov 2, 2000 ============================ 1- Some units were experiencing Modem 6 Alarms and logging Controller 0 FAIL events. Other units were just recording the Controller 0 FAILs. Most units were not exhibiting this problem. The source of the Alarms and Events is an occasional unsucessful read of the 6th Modem that results in the Controller thinking that the DSP Modem is trying to send many messages to the Controller, which it is not. The time spent processing these messages results in the Controller 0 FAIL Events. The incorrect data sometimes garbles a message pointer to the point that all future attempts to read the DSP Modem will fail. This results in the Modem 6 Alarm. This problem should be successfully avoided in this version. Version 1.07.00 Aug 15, 2000 ============================= 1- Digital Pad Detected, RBS links detected, and RBS pattern detected now work for V.90 as well as K56Flex. 2- The D-channel HDLC buffers were getting 'confused' sometimes when a loss-of-frame condition occurred repeatedly on the PRI interface. Safeguards were put in place, and the buffer mechanism is completely restarted when correct framing is detected on the PRI. Checksum: 09390CF2 Version 1.06.01 July 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. This has been fixed. Version 1.06.00 July 5, 2000 ============================= 1- Added ROUTE to HELP. 2- Fixed problem in SEND RAW. Continued lines inside of curly braces were sometimes not working if there was not a leading space on each continued line. 3- There were problems in upgrading from 1.05.18 or lower to 1.05.19. Changes were made to align variables so that upgrading from 1.05.18 or lower to 1.06.00 or higher will be more painless. When upgrading from 1.05.19, SYS and TABLE values might be lost, so record the settings before upgrading. 4- Made changes to save IP ROUTES when upgrading from 1.05.18 or lower. When upgrading from 1.05.19, DEFAULT routes might be preserved (those 0.0.0.0 routes to a gateway), but other routes will be lost. 5- SYS PASSWORD ON now requires the password to be supplied: SYS PASSWORD ON This prevents activating the password feature when there is an existing (and perhaps unknown) password. Version 1.05.19 June 14, 2000 ============================== 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 turn protection ON/OFF SYS PASSWORD to check ON/OFF status SYS PASSWORD NEW new_password to specify password (up to 10 chars) 2- Changes to enhance ability to connect with Ascend V.90 modems. Fixed problems with connecting with some 1995 Rockwell-based V.34 modems. Accommodate client V.90 modems that overrun length of JA frames. 3- Added more options for configuring outgoing test calls. V.90, K56Flex, V.34, and V.32 can be enabled or disabled for each call. The following commands were added to support this capability. TEST V90 TEST K56FLEX TEST V34 TEST V32 Note that V.22 (2400 baud) is always enabled. Version 1.05.18 May 11, 2000 ============================= 1- Added SYS NT command to allow 1575 to emulate the 'switch' side of the PRI for lab testing and certain configurations. However, even with SYS NT configured (as opposed to the normal SYS TE), the 1575 is still loop timed, requiring that the opposite end supply a timed T1 signal. 2- Improvements in functionality of DSP modems. Some improvement in negotiating connections with Lucent modems and old-style Rockwell V.34 modems. Version 1.05.17, Mar 18, 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. 3- Modified memory read/write timing in response to memory self-test failures in a few units. The memory chips affected are only used during software downloads. Version 1.05.15, Mar 03, 2000 ============================= 1- More diagnostic information available. Increased size of Controller Modem Event log used for debugging. Version 1.05.14, Feb 24, 2000 ============================= 1- Show that digital pad detect and RBS information are not available for V.90 calls for now. This capability will be implemented soon. 2- Make sure frequency vs. amplitude graph data (probing data) is omitted for V.32bis, V.32, and other carrier families that preceeded V.34. 3- Show the Rx and Tx data rates correctly for V.32 and V.32bis. They are always the same, but only one was being displayed correctly. Version 1.05.13, Feb 16, 2000 ============================= 1- Corrected problem with garbled output from Port 6902. Version 1.05.12, Feb 08, 2000 ============================= 1- SYS YEAR command was not working correctly (for configuring 2 or 4 digit year). This has been corrected. 2- Improvements in functionality of DSP modems. 3- Corrected problem of not answering calls from V.32 or V.32bis modems. 4- Single-line CALL LOG (CL) summary will now show when an incoming call was from a FAX modem attempting to send a FAX. This seems to be a common occurence. 5- Graph display was corrupted for CL 93 (because of a memory access problem). The CL 93 NOGRAPH data was being shown correctly. This has been corrected. Version 1.05.11, Jan 14, 2000 ============================= 1- Added indication when an incoming call was from a FAX modem attempting to send a FAX. Version 1.05.10, Jan 12, 2000 ============================= 1- Corrected a problem with incoming V.90 calls from internal modems using Lucent chip set. This fix may improve connections with other modems as well. The calls were treated as not connected although a V.90 connection was actually established. Version 1.05.09, Dec 29, 1999 ============================= 1- Improvements for the DSP modems for the purpose of increasing the reliability and consistency of call connections. Version 1.05.08, Dec 21, 1999 ============================= 1- Fixed error in CALLS LOG (CL) NOGRAPH frequency/amplitude data. Decimal portion of data values were incorrect. 2- Reformatted single line CL display summary to add date. Reduced Time of Disconnect to Hour/Minute only, and reduced Duration to Minutes/Seconds only. 3- Some changes to CALLS LOG (CL) detailed display. Moved Time/Duration up to 2nd line and expanded to 2 lines for clarity. Enhanced the Overlay Trace output. 4- Increased connection timeout from 60 seconds to 90 seconds for incoming and outgoing calls. Version 1.05.06, Nov 19, 1999 ============================= 1- Correction to HDLC Tx and Rx window sizes that might affect the functionality of the LAPM error-correcting protocol. Version 1.05.05, Nov 18, 1999 ============================= 1- Added Caller Id to results sent to caller. Rearranged slightly. 2- Added ability to retrieve actually frequency vs. amplitude probing data instead of seeing in graph form. Adding NOGRAPH to end of CL (CALLS LOG) or CF (CALLS FAILED) command strings will give data in tabular form instead of graph form. For example: CL 7 NOGRAPH retrieve entry 7 with tabular data CL 11 retrieve entry 11 with graph CF 24 NOGRAPH retrieve failed entry 24 tabular data 3- Ethernet (telnet) downloads will be even faster now. Characters will not be echoed while downloading. This reduces the Ethernet traffic and speeds up the process. 4- Some improvements were made in the modem connections and negotiation software. Version 1.05.02, Sep 14, 1999 ============================= 1- 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 1.05.01, Sep 7, 1999 ============================ 1- Added the capability to load future software upgrades via a Telnet session over the ethernet connection. However, Version 1.05.01 must be loaded via the RS232 like the previous versions. All future releases can then optionally be downloaded via TCP/IP, once Version 1.05.01 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. 2- Added new alarms and fault detection. There are now alarms and Event Log (and Port 6903) entries for Modem failures and Controller processor failures. Each TSI-1575 has 4 Controller processors and 23 Modems. Version 1.04.10, Aug 11, 1999 ============================= 1- Corrected a bug introduced in last revision - the time-of-day was freezing for up to one minute after the time or date was set. Version 1.04.09, Aug 4, 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. Version 1.04.08, July 20, 1999 ============================== 1- Corrected a problem that occasionally caused incoming calls to be dropped after about 1 second. Version 1.04.07, July 1, 1999 ============================= 1- Drop outbound call if Progress Indicator with "In band information available" is received after sending SETUP. 2- Added TABLE NONE entry. Does not prompt for Name and Number. Does not run test. Does perform connection and records baud rate and information for Freq vs. Ampl graph. 3- Added PING utility (see HELP DIAGNOSTIC) for troubleshooting IP connections. 4- Some reformatting of CALLS LOG information. 5- The Progress Indicator information element is now more fully decoded in the D-channel log. Version 1.04.06, June 29, 1999 ============================== 1- Installed a new release of the DSP modem code. Some more modem connection enhancements were added. 2- Corrected a problem with the CALLS FAILED log length. 3- Added the RBS pattern to the CALLS LOG. Version 1.04.05, June 25, 1999 ============================== 1- Change to work correctly with a telnet session from Procomm Plus for Windows. Enter key was not terminating the command. 2- Setting SYSTEM TELNETIDLE 0 will disable the timeout for an idle telnet user. Version 1.04.04, 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- Corrected a problem encountered with Boca 56K modems. Increased the LAPM HDLC window size for Receives to 2. Modem was not receiving characters after the first few lines. 3- 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. 4- Added digital attenuation detected to CALLS LOG. Version 1.04.01, June 16, 1999 ============================== 1- Added the capability to monitor the alarm and general status of the 1575 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 1575 Event log, which includes all SNMP traps that the 1575 will send. The 1575 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. 2- Issuing the SYS command was causing the Layer 2 status area to be overwritten, which was causing severe problems with the D-channel. This has been corrected. 3- ROUTE, CMNTY, and TRECS settings are now being properly recorded in the non-volatile memory area. 4- Added support for Codeset 5 DISPLAY TEXT information element in the D-channel log display. 5- Installed a new release of the DSP modem code. This should improve the connection negotiation results with some modem types. 6- Corrected the Signal-to-Noise (SNR) calculation. Previous results were about 8 dB too high. 7- The Welcome message given to calling users was being truncated after about 3 lines. This was corrected. 8- Changed the labeling given to calling users to Upload and Download from Tx and Rx to reduce confusion. 9- Added the Rx and Tx tariff rates to the CALLS LOG display. 10- Added the software version to the CALLS LOG display. 11- Added the software version to the SYS display. 12- Some enhancments were implemented to facilitate sending text to the calling modem when a very slow, noisy connection has been established.
