 +
The '''TST console''' is a part of the ICX and AlphaCom Software. It is primary used as a debugging tool for software developers.
  
 +
The TST console can be useful for troubleshooting. The TST console also gives direct access to the system memory, making it possible to modify parameters not available from the [[AlphaPro]] programming tool.

When troubleshooting an AlphaNet connection, you should first find out if AlphaNet ''data link'' is OK. You can use the dt (data trace) command to check if the AlphaNet data is ok. From the TST prompt enter dt+2+2 to start trace. Enter dt+<enter><enter><enter> to switch it off.

AlphaCom icon 300px.png
The TST console

The TST console is a part of the ICX and AlphaCom Software. It is primary used as a debugging tool for software developers.

The TST console can be useful for troubleshooting. The TST console also gives direct access to the system memory, making it possible to modify parameters not available from the AlphaPro programming tool.

Accessing the TST Console

The TST console is accessed from the Linux Console.

Type "tst" at the Linux command prompt to start the TST console
The "TST-TARGET" prompt shows that the TST console is activated
  1. Start the Linux Console
  2. Depending on the system, on the Linux command prompt, type:
    1. ICX System: tst-amcd
    2. AlphaCom: tst
  3. Now the TST Console is activated
  4. Press Ctrl-C to exit the TST console and return to Linux console

tstdb 4    - Trace of DIP Messages between AlphaCom and IP Stations


NVRAM editor

nvram editor

Command: nvram

This command can be use to inspect or modify the memory.

Note that modification will not be part of the AlphaPro database

How to use:

  • On the TST prompt, type nvram, then <Enter> twice
  • You get a menu with line numbers
  • Enter a number to select a menu line or a submenu line
  • When a value is displayed, it can be changed by typing a new number, then <enter>
  • Back one step: press ”-”, then <enter>

                    Codec is also used between PCMC and RTPP, i.e. from backplane to VoIP. 
                    32 codecs available.
RTPP              - "RTP Packetizer". Makes “Real-time Transport Protocol” packets after 
                    the codec has converted PCM audio to G7xx.



Read Error Buffer

Command: err
This command will read the content of the Error Buffer

  • Internal buffer in NVRAM were special events are logged
  • Read out buffer to get general impression of the health of the exchange
  • Find exact reason for a reset
  • The information is very ”software technical”
  • Included in the general logging facilities of AlphaCom E
- Log source ”AlphaCom Debug Log”
  • Three levels:
- Disaster – Exchange reset. The state of the exchange is so bad that the software does a controlled reset to restore normal operation.
- Error – The software handles a problem by e.g. aborting an operation and returning to idle, but logs a message
- Warning – Information to the user. Often identical to texts sent to the log port

Remote Login

  • ”rlogin” – Remote TST Console Feature
- Log on to the TST on remote node or slave modules

- Type ”bye” to revert back to local exchange, and ”bye” once again to exit TST


List Boards

rack” – List Boards

  • Gives overview of boards and hardware resources of a board
  • Type ”rack” + <enter> + <enter> to list all boards
List Boards.jpg
















Data Link Trace

"dt” – Data Link Trace

  • Useful to debug AlphaNet or other Data Protocol problems
  • Activate by typing ”dt” + <enter>:
Data Link Trace.jpg














To activate a continous error trace: dt + <enter> + <enter> + 1 + <enter>
Turn off the trace dt + <enter> + <enter> + <enter>
AlphaNet idle frames: dt + <enter> + 2 + <enter> + 2 + <enter>
AlphaNet application messages: dt + <enter> + 1 + <enter> + 2 + <enter>
AlphaNet occational failures: dt + <enter> + 1 + <enter> + 1 + <enter>


When troubleshooting an AlphaNet connection, you should first find out if AlphaNet data link is OK. You can use the dt (data trace) command to check if the AlphaNet data is ok. From the TST prompt enter dt+2+2 to start trace. Enter dt+<enter><enter><enter> to switch it off.

Example 1: AlphaNet on data port 9 (IP). The Send and Receive idle frames shows that the AlphaNet data communication is OK: 

DPLC(9) Recv(T1 S5 A0 L4)
DPLC(9) Expect(S5)
DPLC(9) Send(T1 S3 A0 L4)
DPLC(9) Recv(T2 S3 A0 L0)

DPLC(9) DelWin(------)

Example 2: AlphaNet on data port 4. The AlphaNet data communication is faulty. You can see Send but no Receive, instead there is a timer started after each Send: 

DPLC(4) TIMER in READY, counter: 2
DPLC(4) Send(T1 S1 A0 L4)
DPLC(4) TIMER in READY, counter: 3
DPLC(4) Send(T1 S1 A0 L4)
DPLC(4) TIMER in READY, counter: 4
DPLC(4) Send(T1 S1 A0 L4)
DPLC(4) TIMER in READY, counter: 5
DPLC(4) Send(T1 S1 A0 L4)
DPLC(4) TIMER in READY, counter: 6

Data Link Statistics

”sswrep” – Data Link Statistics

  • Shows quality statistics on a data link
  • Useful if problems with AlphaNet
  • The ”sswrep” command asks for serial port number
  • Three counters are displayed:
- P1: Total number of messages received
- P2: Number of messages with wrong checksum received
- P3: Number of messages received out of sequence
Data Link Statistics.jpg











- The counters are set to 0 when the total number of messages received reaches 50000

SysLog

$LOG commands in the event handler and the syslog in general can be viewed in the TST console. Simply type syslog and select the trace level. Level 5 will only show $LOG entries, whilst level 7 will show all the syslog. (New in AMCD 11.1.3.3).
