AlphaCom 10.xx Release Notes

<br\>

AMC 10.60.3.7(2010-01-27)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.50.

System upgrade file:<br\> alpha_sys_10_60_3_7.tbz2<br\>

Precautions:<br\> alpha_sys_10_51.tbz2 must be installed.<br\><br\> AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

BZ 315 IP station fails UK style ringing tone from SIP

The alternative ringing pattern and tone used to indicate incoming call from SIP was not available on the IP stations.


Enhancement

To avoid problems with the AlphaNet changes done in 10.60.3.6 a safety filter is added to AlphaNet data routing. This will inhibit critical issues with old and new nodes in a transit routed AlphaNet. Old node will not receive Alternative routing and broadcast messages able to triggering faults in the AlphaNet data router.

AMC 10.60.3.6(2010-01-21)

Release: Please use 10.60.3.7 or newer.
/opt/amc/bin/amcd
NVRAM version 10.50.

System upgrade file:<br\> alpha_sys_10_60_3_6.tbz2<br\>

Precautions:<br\> alpha_sys_10_51.tbz2 must be installed.<br\><br\> AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Incompatible changes are made to the AlphaNet protocol in the Network layer header related to forwarding of broadcasts and re-routed messages. In networks where transit routing is used, all nodes should be upgraded at once.<br\> Please use 10.60.3.7 or newer to avoid critical problems in incompatibility.

Errors Corrected

BZ 310 and BZ 311 Broadcast and Alternative routing in AlphaNet

AlphaNet Data Protocol message routing: Broadcast and alternative routing in networks with transit exchanges did not work. BZ 310 and BZ 311. This fix is highly recommended to install in networks where transit routing is used.<br\>

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.50.

System upgrade file:<br\> alpha_sys_10_60_3_5.tbz2<br\>

Precautions:<br\> alpha_sys_10_51.tbz2 must be installed.<br\><br\> AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

BZ 288 $C and $DISCON_ST disconnected wrong AlphaNet station

If a $DISCON_ST or $C was not sent to det refered stations local node and the refered station was configured as a global number, the physical no = node number of the global number would be reset. Now the $C and $DISCON_ST (and M press and release) are forwarded to the correct node.

BZ 307 Slave module in contant reset after set to Factory Default

If an slave module is factory reset, the slave module could end up in an reset loop. Fixed. (A workaround is to disconnect master, the reset will stop. Then program a DAK key from any station on the slave module, then reconnect master)

Automatic M key on global group calls

Global Group now uses the auto_m_key flag from the related local group

M-key use on outgoing handset operated SIP calls

If calling out on a SIP trunk and using handset, the use of M-key could result in reset.

Line Echo Canceller (LEC) not started

LEC missing in two situations: 1. When calling from "SIP as station" to analogue station using handset. <br\> 2. Dialing AlphaNet area code, then lifting handset, then call directory number did not start LEC thus echo on the AlphaNet link.

ex_profile.flags.local_AlphaPro = 1

New 4 digit software version system

Now possible to do updates on release version.


Log System (Syslog)

<br\> The logging is handled by the syslog-ng log daemon. This can be configured to route the logs to different media. The log can be stored on on-board flash, or sent over the network with different protocols.

Known Issues

Large log files on on-board FLASH

The log is stored on a limited sized Flash partition by a file system. Routines to handle larger log amounts, like automatic clean up of older files have been implemented, but we still experience problems if the log rates get to large. These problems occur before a theoretical log rate versus free space analysis, mainly because of file system issues with a small number of available flash sectors. This file system factor makes it difficult to make an accurate estimate of handled log rates so the following is based on experience:

Limits: 

Log rates lesser than 1440 events a day (an average of one each minute) should be handled with no problem.
Log rates of 17280 events a day (one each 5th second) is experienced to give problems.

Guideline: 

If you are above 1440 events a day you should evaluate to use the Remote Syslog option, and turn off the Local Filesystem Log.
If you are closer to the 17280 events log rate we strongly advise to use only the Remote Syslog option. 
If your system are logging above the 1440 events a day to the filesystem you should regularly monitor the logs.

Note: 

From AlphaCom 10.23 a log limiter on the System and Debug log is implemented, allowing for a maximum of 60 events a hour. 
If this limit  is reached, it will be notified by a log message. Because of this limit the above guidline will only apply 
to the Statistics log.

Hardware Versions

<br\>

AMC hardware versions

Known problems AMC hardware 8000/4

None as of now<br\><br\>

Known problems AMC hardware 8000/2

Issue 2747: RCI not supported on ACE7:

RCI not supported on ACE7. The RCI signals on P1-c19 and P1-c22 are terminated in test points on AMC-IP. <br\>

Issue 2741: Redundancy control from APC:

The redundancy control system from APC is not working (software and hardware).<br\>

Issue 2787: AMC serial port: No RX, no data on TX:

It turns out that the RS232-drivers on the AMC-IP-board have an automatic shutdown when it detects missing received data (illegal voltage levels). This will be fixed in future hardware version, but it can be fixed on current hardware by a minor modification. Remove R698 and R695. The pins must be connected to Vcc (3,3V). <br\>

Issue 2806: “Temperature Alarm" in ACE.7:

This problem is probably related to the fact that the AMC-IP board never had a connection to the over-temp. signal from the ACE7 backplane. This is related to the problems with RCIs from the same backplane.

AMC Filter board

Issue 2723: RS422/RS485 Signal Pinning:

The pin out for RS422 signals on the filter print for E20 and E26 differs from the pin out on the E7. The Rx+ is switched with the Rx- and the Tx+ is switched with the Tx-. The only consequence is that the same cable can't be used on E7 and the E20-series. From filter print version 3 (DB8001/3) the mapping is correct.<br\>
