AlphaCom 11.xx Release Notes

<br\>

AMC 11.2.3.1(2011-07-05)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 11.02.

System upgrade file:<br\> alpha_sys-11.2.3.1.apkg<br\> Running this software on an AMC 11 hardware require use of STIC

Errors Corrected

BZ 532 BZ 441 Configuration of IP only node - XE1 in node routing

When connecting XE1 in AlphaNet with nodes having analogue stations the XE7/20/26 routing tables should be configured with the "IP only" flag in AlphaPro to force duplex control in local node when talking to XE1.

$COPY_MAIL with Lower Priority

When lowering priority with $CPYM the station with the mail in queue was not informed thus when lowering from urgent feature reminder to no feature reminder, the urgent feature reminder continued on the station.

BZ 534 BZ 597 IP Station as MCS Station

Problems with some dedicate MCS (MCS_station) functions when using an IP station.

IP Station Volume Level Adjusted from IP Station Volume Control now Stores Same Values as used by AlphaPro

Previously "in between" values compared to AlphaPro volume values could be stored when changing volume from the IP station, thus no volume was shown in AlphaPro after get all.

BZ 581 Try to Avoid Trans Coding in Calls from SIP Station to SIP Station

Previously the initial codec used for the call initiating SIP station was not stored thus the setup to the destination SIP station would not use the initial codec as preferred.

BZ 569 The OPC Server did not Receive the Correct Mail Information from Remote Nodes

The $EXT_MAIL from a node with sending station of the mail from another nodes did not contain a correct source "net obj ref"

BZ 533 Reset when Dialing 7984 when "Program On"

Fixed reset when 7984 activated from DAK key during program on.

BZ 544 $CALL setup with call option flag 1 terminate after 15seconds in AlphaNet

Using call option 1 for $CALL setup in AlphaNet terminated call from start node within 15 seconds.

BZ 476 Volume Of IP stations after Restore of Backup

The volume of IP stations got a invalid value after restore of backup.

BZ 499 Feature Reminder Speed of IP station

The feature reminder led blink speed is now the same as for analogue stations.

BZ 502 IND Message with station 0

The programming of "IND 0 0 0 0 OFF" from the event handler would reset the exchange.

BZ 443 Call Timer for Transit Calls to RMD

To avoid endless transit calls between two Ring Master exchanges, the standard call timer is started in the last transit exchange.

BZ 329 Avoid crossing of AUDIO_PATH_DISCONNECT

Crossing AUDIO_PATH_DISCONNECT messages between SIPD and AlphaCom generated SysLog noise.

BZ 432 Parsing of DP messages

In Simple Link Layer (and from EVH) the string "$1" would reset the exchange.

BZ 427 AMC reset when alarm message is sent to active speaker in SX

BZ 482 Node Number not Updated after Restore of Backup

The node number is stored on the STIC, this was not updated after restore of a backup.

BZ 472 Echo Canceler Active During Private Ringing

The sound of the private tinging tone could be muted by the Echo Canceler in the IP station.


Enhancement

High Availability

  • Information to be updated

IP-ARIO support

Support of IP-ARIO.

  • DAK as RCI
  • Logical RCI
  • Logical RCO
  • Remote RS232

New and changed event handler macros 

wudd        (Added label and string variables)
%udd        (Added label and string variables)
gind        (NEW  group version of ind)
%paf        (NEW, PA fault in UDP group check)
%pai        (NEW, PA fault indicator in DAK block)
%pap        (NEW, PA fault mail priority)
%prci       (NEW, Current Physical RCI state)
%prco       (NEW, Current Physical RCO state)

$DP messages: 

$PA_CMD     (NEW, PA command, ACK/CLEAR)
$SET_IPRCO  (NEW, Set physical RCO on IP station/IP-ARIO)
$CANCEL_MAIL(Added option for delete mail with specific priority, Mail-id = 253)

Support of IP Dual Display

DAK display control of the IP Dual Display.

Recording

Support for STENTOFON_Recording.

BZ 479 Feature From Idle Event Trigger

A new event trigger 37 Feature From Idle trigger "ON" event related to "feature directory number" of the feature code dialed from the owner station or UDP group.

Added Timeout to the AlphaNet Broadcast Forward Table

When connecting AMC9 and AMC_IP the broadcast numbering could lead to problems with broadcast messages from AMC9.

$VOL Without Volume Parameter Refresh Current Volume Setting on the Station

Handy when using %gnv - $snv from event handler to manipulate volume of stations, (nvram volume value does not correspond to the $VOL parameter)

Added Connect to Group Message

$CONN_2_GROUP This DP message allow the initiator of a group call to also receive the audio from the group call. Used for Special stations with separate mic and speaker and for production test of IP-ARIO.

Default use 20ms RTP packages in Multi Module audio

The package size used for multi module is based on the setting of RTP package size for the routing entry to the local node. This value is default to 20ms but after a SendAll from AlphaPro the value is set to 0. This gave 10ms package size, this is now changed to be interpreted as 20ms.

BZ 459 RTP Stream Station

Implementation of a dummy IP station configured from AlphaPro. Can be used to stream audio to and from the exchange. Use $VAC to configure IP address and port to be used.

BZ 434 $CALL with "Listen" Option

Possible to start a silence call to an IP station. No LED or loudspeaker turned on the B party.

Statistics SysLog

  • When Calling a Trunk the private ringing and busy state was missing in statistic log.
  • Last received reply code from SIP during outgoing trunk calls is stored in the Call Statistic log: "S180"

Added 10 Minutes Timeout to OPC Server Registration in AlphaCom

After a OPC server was brief connected to AlphaCom the OPC and node address was reserved until next reset. (Not possible to connect OPC through other nodes) Now the OPC address is free again if the OPC has been disconnected for 10 minutes.

BZ 109 Faster Scheduler (Event Type) catchup

Catchup one minute each 100ms (was each 1 second).

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\>
