==={{Bugzilla|92}}  Speech from other conversation when calling IP trunk line===
 +
When calling an IP trunk line from an IP or SIP station. During call set-up there could be some ms of audio from an other used IP trunk.
 +
==={{Bugzilla|119}} Event Handler - Received mail go OFF before Conversation goes ON===
 +
When answering a call request the Conversation event (07 or 08) did go ON before the Received Mail event (10) goes OFF. This caused some problems when for instance using these events for CCTV control.
 +
 
 +
==={{Bugzilla|174}} Ringing to SIP times out after 41 seconds===
 +
It was not possible to increase timeout on ringing to SIP beyond 41 seconds.
 +

 +
From 10.52, the event is correctly executed, but the call is not automatically cancelled.
 +
==={{Bugzilla|196}} Alternative routing check when using analogue transit nodes===
 +
Example: <br />
 +
Node audio from A to B is configured as first route via C. <br />
 +
Node number A is higher than node number C (This implies C is owning the AGA/E1 link)<br />
 +
If node C is down alternative routing would not be used.<br />
 +
 
 +
==={{Bugzilla|198}} Snatch of AlphaNet VoIP priority calls with static licenses===
 +
Priority calls and priority global group calls over VoIP AlphaNet did not work if all lines are busy and static AlphaNet license was used.
 +
==={{Bugzilla|199}} Groupcall including IP stations was blocked if no multi module or AlphaNet licenses===
 +
(Error was introduced in 10.53)
 +
==={{Bugzilla|200}} Use of $DIAL_DAK when station listening to Simplex conference===
 +
$DIAL_DAK can now be used also when station is listening to conference.
 +

 +
[[SET_LOGICAL_RCO | $SLRC]] will now not "assert" the exchange when tried to be used out of the logical RCO range.
 +
==={{Bugzilla|203}} [[GROUP_MEMBERSHIP |$GRM]] now synchronize to flash database===
 +
When using the [[GROUP_MEMBERSHIP|$GRM]] message and resetting the AlphaCom the changes would not survive reset.
 +
==={{Bugzilla|204}} [[Faulty Station Line (Event Type)]] report missing after reset===
 +
The faulty station event is now reported On after reset/power-off of AlphaCom.
 +
==={{Bugzilla|205}} Call in from SIP trunk===
 +
Is now allowed to listen to [[Absence Messages]], and to activate [[Pocket Paging]].
 +
==={{Bugzilla|207}} IP station Call LED on when making AlphaNet call to busy or private station===
 +
The IP station Call LED is now off when call to busy or private station.
 +
===[[SIPD]]: use [[Class of service]] 15, not 16, for incoming trunk calls===
 +
===Call Request Search system===
 +
There was some issues when call request search was used for forwarding regular "623" call requests.
 +
===Reactivation of active call request could send mail to wrong queue station===
 +
If several simultaneous call request are activated and reactivated to different groups or queue station, 
 +
a call request could end up in both the correct and a unintended call queue.
 +
 
 +
===PrisCom DAK acknowledge from station could generated "DAK_as_RCI" event OFF===
 +
===Chilly reset of slave module===
 +
Chilly reset of slave modules in nodes with the "copy nvram to slaves" option active would not restart in slave mode without doing a factory reset
 +
 
 +
==Functional changes / Enhancement==
 +
==={{Bugzilla|139}} SIP -> IP station call now try to avoid transcoding===
 +
Incoming calls from SIP in G711 will use G711 also to the IP station if the IP station is configured with "Use Best Available Codec".
 +
==={{Bugzilla|156}} Line error text changed to "StError 101"===
 +
The original text "L P65-1-2 D2347" is now changed to "StError 2347". (Can be configured back from the MDF editor in AlphaPro)
 +
==={{Bugzilla|173}} Slave: Inhibit free license timer when using multi module license===
 +
To reduce confusion the free license period in the slaves is removed when master module has a multi module license. <br />
 +
AlphaWeb will show multi module license in slaves.
 +
==={{Bugzilla|182}} Include an option to tear down the TCP connection after data is sent===
 +
(also see {{Bugzilla|108}}). AlphaPro support pending.
 +
==={{Bugzilla|191}} New Event handler trigger for C-key use added===
 +
[[C-key_%28Event_Type%29 | C-key event]]
 +
==={{Bugzilla|211}} AlphaNet broadcast messages as unicast===
 +
Node broadcast messages are converted to unicast messages to all known nodes in the local AlphaNet routing table. This is done to decrease traffic in an all-to-all IP connected AlphaNet system.
 +
 
 +
===New setting for limiting the max number of trunks used toward each node===
 +
14 &963005 .module_profile.node_profile[70].max_trunks = 1 (0x01)
 +
(Default 0 = no limit)
 +
AlphaPro support pending.
 +
===Debounce of ON/OFF hook signalling from ATLB===
 +
To to reduce unintended resetting of conversation/ringing a debounce function was added to AMC. <br />
 +
But due to delay in signaling from the ATLB card this function is not useful in most situations.
 +
Nvram flag: ex_profile.flags.HOOK_debounce = 1
 +
===Support for two OPC servers===
 +
Two OPC servers can be connected simultaneously to the same AlphaNet. (OPC server software supporting dual OPC needed)
 +

Release: Official, available on request
 +
/opt/amc/bin/amcd
 +
NVRAM version 10.50.
 +
 
 +
'''System upgrade file:'''<br />
 +
alpha_sys_10_54.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==
 +
===Broadcast flooding in multi node AlphaNet===
 +
During reset of AlphaCom with alpha_sys versions from 1043x to 1053 CANCEL_MAIL AlphaNet messages from trunk-proxy stations are sent as node broadcast.<br />
 +
The number of trunk-proxy stations are dependent on IP links plus the configuration of AE1 and AGA AlphaNet links.<br />
 +
In an multi node AlphaNet IP configuration with all nodes communicate to all other nodes a broadcast will go from the origin node to all other nodes. The "other" nodes will then send the broadcast to all other nodes except for the node from where the broadcast was received. <br />
 +
A table of unique reference for each broadcast is used for throwing away broadcasts already received. <br />
 +
If the number of active broadcast is higher than the size of the broadcast reference table in combination of some AlphaNet links with delay, nodes can start resending "old" broadcast. This can reach an amount of messages that makes the AlphaCom software watchdog activate a reset generating lots of new CANCEL_MAIL broadcast, then a situation of cyclic reset of all nodes can occur.
 +
To avoid this problem the following improvements are made:
 +
 
 +
*Remove broadcast of CANCEL_MAIL from proxy station after reset.
 +
*Avoid full TCP sockets blocking the InterCom application software thus making the software watchdog reset.
 +
 
 +
==={{Bugzilla|193}} Bugfix of search type call request when receiver station is busy===
 +
 
 +
=AMC 1053(2009-03-23)=
 +
Release: Official, available on request
 +
/opt/amc/bin/amcd
 +
NVRAM version 10.50.
 +
New State Data structure. When upgrading all state data will be lost. (A [[Chilly start of AMC-IP]] will be preformed) <br />
 +
If currently running on free license period an upgrade will reset the license timer to 0. <br />
 +
A factory reset must be preformed to re initiate the free license period.
 +
 
 +
'''System upgrade file:'''<br />
 +
alpha_sys_10_53.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==
 +
==={{Bugzilla|155}} Slave missing in multimodule blocks inter-module calls===
 +
Now if a slave is missing other slaves can still receive calls.
 +
===Call between slaves does not seize license in Master===
 +
Call between two slave [[Module|modules]] wrongly seized a [[licenses|license]] in the master in addition to the correct licenses in each of the two slaves.
 +
==={{Bugzilla|159}} Double DTMF signaling from ATLB12 in combination with SIP trunks===
 +
Now both ATLB-6 and ATLB-12 is configured for reporting of signalling during conversation to AMC. <br />
 +
This is done to be able to do digit signalling to Billing when the SIP-TRUNK is connected. <br />
 +
The digit signalling is filtered out in AMC to avoid SIP_INFO being sent to the SIP gateway making double set of DTMF tones.<br />
 +
To avoid double DTMF problems on PNCI the MPC data is also filtered from ATLB during conversation.
 +
 
 +
==={{Bugzilla|162}} Display text update with Billing and alternative trunk===
 +
When Billing alternative trunk is activated after pin code dialling, the trunk name is updated in the display of the station.
 +
===ACDP message DELETE_MAIL could generate reset===
 +
$DELETE_MAIL with station parameter resolving to an illegal physical number will now give an ILLEGAL_PARAM instead of reset.
 +
 
 +
==Functional changes / Enhancement==
 +
===Increased Software Priority on the IP station communication===
 +
To avoid internal buffers overflow in systems with a large number of IP stations the communication to IP stations has been given higher priority
 +
===New Event Handler Macros "[[%25lbd|ldb]]" and "[[%25prog|prog]]"===
 +
Event handler macro "%lbd" for reading out local board number. Typical used for dual AMC configuration.
 +
Event handler macro "%prog(st_ind)" for reading out current program number 1->xx active on a station. Return 0 if no program active.
 +
 
 +
===Private Ringing Tone in IP stations===
 +
Private ringing sequence in IP stations is now completely handled in the IP station to avoid AMC load when hundreds of IP stations is ringing in parallel. <br />
 +
IP stations with AUDIO event of type "Private ringing" related to the stations are still handled by AMC to obtain synchronous event state handling with the ringing tone.
 +
===Better performance of IP station PING command===
 +
Optimized IP station PING-PONG system. Equal functionality.
 +
===Mail pool increased to 2500 mails===
 +
Mail pool is increased from 1104 to 2500 mails. (Nvram state is changed)
 +
 
 +
==={{Bugzilla|148}}Incoming Call from SIP with different ringing tone===
 +
Added new nvram flag ".ex_profile.flags.trunk_alt_priv_ring". When set to "1" all calls from SIP trunks will use "UK style ringing tone".
 +
 
 +
===Avoid signalling fault from analogue sub stations===
 +
From substations a short press on ID + M can be signalled as ID. When the global flag: "ID_and_IDM_to_IDC_CRM" is set, wait for 300 ms before ID is accepted.
 +
==={{Bugzilla|147}} Muted busy tone removed from SIP trunks===
 +
SIP stations/trunks does not get the muted busy tone (Same behaviour as PNCI system)
 +
===Start of ATLB-ATLB conversation no need for duplex resources===
 +
When starting a call between two local ATLB stations no duplex resources are allocated. <br />
 +
When incoming call from SIP to ATLB no duplex resources are allocated.<br />
 +
This will give the possibility for setting up calls in system with only ATLB12 cards.
 +

==={{Bugzilla|106}}  [[PUT_STRING]] : MPC header corrected from 0x80 to 0x00===
 +
==={{Bugzilla|116}} AMCD crashed in error report function===
 +
The error report function could in some special cases reset AMC.
 +
==={{Bugzilla|117}} OPC: Non-existing stations are registered, consuming license===
 +
[[Licenses#OPC_Server|OPC license use]]
 +
==={{Bugzilla|118}} Call Req not deleted when using 7638 in Absent status.===
 +
==={{Bugzilla|127}} IP station multicast ping during free license period===
 +
During free license period the multicast ping system of IP stations would not work correctly. IP multicast group call will not work.
 +
==={{Bugzilla|130}} RCO trouble on IP master at physical number 67&68===
 +
RCO related to IP stations with physical number as the slave module devices numbers (66-68) had issues. (1052x0119)
 +
==={{Bugzilla|135}} AMC reset when using data commands to answer ringing group call===
 +
When using $CALL Lx Lz W64 the station in call requester mode type ringing group would be released double to the allocator. This is now prevented.
 +
==={{Bugzilla|136}} Duplex AlphaNet Call to IP station===
 +
Lifting A-handset did not go to "open" Duplex.
 +
==={{Bugzilla|138}} Event conversation outgoing and RingingGroup call from SIP===

 +
==={{Bugzilla|157}}IP resources in standby operation===
 +
Fault on an AMC card in standby operation will remove IP resources from the
 +
allocation table on the master card
 +
 
 +
===Double syslog call statistics for multi module===
 +
When calling from AlphaNet IP to stations on a IP slave module the call statistic would give 2 entries, the second entry with corrupted data.
 +
Double lines could also be generated when calling from AlphaNet IP to IP stations.
 +
 
 +
==Functional changes / Enhancement==
 +
===Support for Billing===
 +
[[Billing_Installation_Guide|Billing installation Guide]]
 +
==={{Bugzilla|54}} [[CALL SETUP|$CALL]] and [[call priority]] now control open/private===
 +
Fixed handling of $CALL so that param#5 call priority is used for calculation of open/private mode of call.
 +
==={{Bugzilla|108}}  Buffer data for TCP client if no connection===
 +
Start connection on write if in wait state.
 +
===[[Chilly start of AMC-IP]] from AlphaWeb===
 +
===Faster restart of slaves in multimodule, when multimodule data over IP.===
 +
Slave modules inform master when it receives TCP connection from Master. Master then proceeds with the startup procedure immediately. Faster connect after reset.
 +
===[[ST_BUSY_BC]]/[[ST_FREE_BC]] broadcasts for AlphaNet audio lines (proxy)===
 +
The [[ST_BUSY_BC]] and [[ST_FREE_BC]] messages now use [[NRF_LOCAL_ENTITY]], in order to avoid confusion with the corresponding events from the end-stations for AlphaNet calls. 
 +
===Codec handling for incoming calls from SIP===
 +
Don't force to codec set in node-profile. Just use best codec offered in INVITE.
 +
===Paging queue improvements===
 +
Allow several simultaneous calls to same receiver, so that a unacknowledged call does not block new calls to same receiver.
 +
===ISO 1745 linklayer improved===
 +
Send outgoing messages immediately, don't poll self if nothing to send.
 +
 
 +
===[[MPP - Mail to Pocket Pager]] improvements===
 +
Max length of Free text increased from 16 to 128. Possible to specify pager address directly in quotes.
 +
===AlphaWeb station list shows 16 character display name===
 +
The station list previously showed only the 12 first characters now it shows 16.
 +
===Only IP station with display can use C-key as private/open key===
 +
DP command C_PRES also generate local C_RELEASE so that open/private mode change does not occurs.
 +
===UDP info added to ST_STATE message===
 +
The [[ST_STATE]] message used for OPC server now includes UDP
 +
===No Echo canceller in use during dial/busy/reset-tone on IP stations===
 +
Local Echo canceller in the IP station is turned off to get stable tones.
 +
===OPC license quantity steps adjusted===
 +
New quantities are: 40,80,160,240,320,400,552
 +
===Multi Module license added===
 +
Multi Module [[Licenses|license]] is only needed in the master module. License define the number of modules possible to connect 1,2 or 3. Always 30 audio channels. For backward compatibility AlphaNet licenses will be used if no Multi module licenses in the license key. AlphaNet-Multi module licenses need licenses in all modules,
 +
 
 +
==={{Bugzilla|124}}Event 34, reporting boards UP/DOWN [[Board_Status_(Event_Type)]]===
 +
New event when cards is going up down. Sub event = card position.
 +
==={{Bugzilla|129}}Billing PIN CODE tone changed===
 +
Handset tone is used for indicating "dial pin code"
 +
===Force conversation to Simplex mode===
 +
Data protocol command added [[SET_SIMPLEX | $SIMP]]
 +
===Improved handling of IP station up messages===
 +
Close socket to IP station in faulty situations.
 +
===Back Plane messages delay to ASVP did also effect VoIP setup speed===
 +
Previously implemented delay of messages to the ASVP card also delayed the VoIP setup time.
 +
===Stability improvement for IP multi module calls===
 +
===Implemented ping-test of analog PrisCom station processor===
 +
"Cellstation" flag must be enabled. Every PrisCom station are tested in combination with the extended line test timer. (IND 99 is sent to the station and IND ack suspected as reply.) If no reply for two tests the station is reported down to ERR and event handler. However the station is still in active state. (1052x213)
 +
===High availability system, IP station down test===
 +
If there has been connection to a configurable number of IP stations (op_constants(0).sbm_ip_st_down_trig) and all IP station connections are lost: set the standby request flag. (1052x213)
 +
===Low level queue size of ACDP protocols increased===
 +
The send queue for multi drop protocols is increased. Low level buffer for incoming bytes is now also flushed if filled up with "rubish"
 +
===Busy/Free messages on MPC from IP Proxy AlphaNet links===
 +
The Busy/Free messages from IP-proxy stations on MPC is removed for better consistence. Busy/Free/Connect from other nodes must be sent from event handler in remote nodes. [[MPC_Data_Protocol#MPC_data_in_AlphaNet|MPC use in AlphaNet]]
 +
===Fader problems in ATLB12===
 +
Due to problems with the faders on ATLB12 cards, the faders and duplex resources is not used for ATLB12 with software versions bellow 05.30.

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-.

Previous Release - AlphaCom 10.xx - Release Notes

Next Release - AlphaCom 10.6x - Release Notes

This document provides the release notes for AlphaCom 10.4 with incremental bug fix releases. The release notes for AlphaCom 10.4 describe new features, improvements and issues fixed after AlphaCom 10.

Software in production: AMC 10.20
Software released date: 2007-04-12
Note 1: We sometimes do bug fixes in older versions while working with a new version. You can’t read the list version by version, and always assume that a correction is included in the next. Be aware of high release numbers, e.g. 06.05 vs. 07.01. Check version dates, and also comments for each version.
Note 2: For each software version the NVRAM version is listed. If the NVRAM version is different, the AMC board must be cold started, and then you must do a SendAll from AlphaPro to restore the configuration.

AlphaCom 10.xx Release Notes



AMC 1056(2009-08-07)

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

System upgrade file:
alpha_sys_10_56.tbz2

Precautions:
alpha_sys_10_51.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

BZ 231 If nvram-battery or state date was corrupted on 1055 the AMCD did not always start after reset

AMC 1055(2009-07-01)

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

System upgrade file:
alpha_sys_10_55.tbz2

Precautions:
alpha_sys_10_51.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

BZ 92 Speech from other conversation when calling IP trunk line

When calling an IP trunk line from an IP or SIP station. During call set-up there could be some ms of audio from an other used IP trunk.

BZ 119 Event Handler - Received mail go OFF before Conversation goes ON

When answering a call request the Conversation event (07 or 08) did go ON before the Received Mail event (10) goes OFF. This caused some problems when for instance using these events for CCTV control.

BZ 174 Ringing to SIP times out after 41 seconds

It was not possible to increase timeout on ringing to SIP beyond 41 seconds.

BZ 195 Event trigger feature 52 or 85 from SIP phone doesn't cancel

From 10.52, the event is correctly executed, but the call is not automatically cancelled.

BZ 196 Alternative routing check when using analogue transit nodes

Example:
Node audio from A to B is configured as first route via C.
Node number A is higher than node number C (This implies C is owning the AGA/E1 link)
If node C is down alternative routing would not be used.

BZ 198 Snatch of AlphaNet VoIP priority calls with static licenses

Priority calls and priority global group calls over VoIP AlphaNet did not work if all lines are busy and static AlphaNet license was used.

BZ 199 Groupcall including IP stations was blocked if no multi module or AlphaNet licenses

(Error was introduced in 10.53)

BZ 200 Use of $DIAL_DAK when station listening to Simplex conference

$DIAL_DAK can now be used also when station is listening to conference.

BZ 201 $SLRC when out of logical RCO range

$SLRC will now not "assert" the exchange when tried to be used out of the logical RCO range.

BZ 203 $GRM now synchronize to flash database

When using the $GRM message and resetting the AlphaCom the changes would not survive reset.

BZ 204 Faulty Station Line (Event Type) report missing after reset

The faulty station event is now reported On after reset/power-off of AlphaCom.

BZ 205 Call in from SIP trunk

Is now allowed to listen to Absence Messages, and to activate Pocket Paging.

BZ 207 IP station Call LED on when making AlphaNet call to busy or private station

The IP station Call LED is now off when call to busy or private station.

SIPD: use Class of service 15, not 16, for incoming trunk calls

Call Request Search system

There was some issues when call request search was used for forwarding regular "623" call requests.

Reactivation of active call request could send mail to wrong queue station

If several simultaneous call request are activated and reactivated to different groups or queue station, a call request could end up in both the correct and a unintended call queue.

PrisCom DAK acknowledge from station could generated "DAK_as_RCI" event OFF

Chilly reset of slave module

Chilly reset of slave modules in nodes with the "copy nvram to slaves" option active would not restart in slave mode without doing a factory reset

Functional changes / Enhancement

BZ 139 SIP -> IP station call now try to avoid transcoding

BZ 211 AlphaNet broadcast messages as unicast

Node broadcast messages are converted to unicast messages to all known nodes in the local AlphaNet routing table. This is done to decrease traffic in an all-to-all IP connected AlphaNet system.

New setting for limiting the max number of trunks used toward each node

14 &963005 .module_profile.node_profile[70].max_trunks = 1 (0x01)
(Default 0 = no limit)

AlphaPro support pending.

Debounce of ON/OFF hook signalling from ATLB

To to reduce unintended resetting of conversation/ringing a debounce function was added to AMC.
But due to delay in signaling from the ATLB card this function is not useful in most situations. 

Nvram flag: ex_profile.flags.HOOK_debounce = 1

Support for two OPC servers

Two OPC servers can be connected simultaneously to the same AlphaNet. (OPC server software supporting dual OPC needed)

Destination SIP IP address shown in node list in AlphaWeb

SIP trunk IP address now also shown when multiple SIP trunks are configured (previously shown as "transit").

Station flag2 bit 12 is used for disabling OPC reporting and OPC license use on station

AlphaPro support pending.

Support of SIP phone as AlphaCom station

SIP phones can now be configured in AlphaPro as stations in the "user and station" menu. Giving more integrated AlphaCom control of the SIP stations.

AMC 1054(2009-06-04)

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

System upgrade file:
alpha_sys_10_54.tbz2

Precautions:
alpha_sys_10_51.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

Broadcast flooding in multi node AlphaNet

During reset of AlphaCom with alpha_sys versions from 1043x to 1053 CANCEL_MAIL AlphaNet messages from trunk-proxy stations are sent as node broadcast.
The number of trunk-proxy stations are dependent on IP links plus the configuration of AE1 and AGA AlphaNet links.
In an multi node AlphaNet IP configuration with all nodes communicate to all other nodes a broadcast will go from the origin node to all other nodes. The "other" nodes will then send the broadcast to all other nodes except for the node from where the broadcast was received.
A table of unique reference for each broadcast is used for throwing away broadcasts already received.
If the number of active broadcast is higher than the size of the broadcast reference table in combination of some AlphaNet links with delay, nodes can start resending "old" broadcast. This can reach an amount of messages that makes the AlphaCom software watchdog activate a reset generating lots of new CANCEL_MAIL broadcast, then a situation of cyclic reset of all nodes can occur. To avoid this problem the following improvements are made:

  • Remove broadcast of CANCEL_MAIL from proxy station after reset.
  • Avoid full TCP sockets blocking the InterCom application software thus making the software watchdog reset.

BZ 193 Bugfix of search type call request when receiver station is busy

AMC 1053(2009-03-23)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.50.
New State Data structure. When upgrading all state data will be lost. (A Chilly start of AMC-IP will be preformed)

A factory reset must be preformed to re initiate the free license period.

System upgrade file:
alpha_sys_10_53.tbz2

Precautions:
alpha_sys_10_51.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

BZ 155 Slave missing in multimodule blocks inter-module calls

Now if a slave is missing other slaves can still receive calls.

Call between slaves does not seize license in Master

Call between two slave modules wrongly seized a license in the master in addition to the correct licenses in each of the two slaves.

BZ 159 Double DTMF signaling from ATLB12 in combination with SIP trunks

Now both ATLB-6 and ATLB-12 is configured for reporting of signalling during conversation to AMC.
This is done to be able to do digit signalling to Billing when the SIP-TRUNK is connected.
The digit signalling is filtered out in AMC to avoid SIP_INFO being sent to the SIP gateway making double set of DTMF tones.
To avoid double DTMF problems on PNCI the MPC data is also filtered from ATLB during conversation.

BZ 162 Display text update with Billing and alternative trunk

When Billing alternative trunk is activated after pin code dialling, the trunk name is updated in the display of the station.

ACDP message DELETE_MAIL could generate reset

$DELETE_MAIL with station parameter resolving to an illegal physical number will now give an ILLEGAL_PARAM instead of reset.

Functional changes / Enhancement

Increased Software Priority on the IP station communication

To avoid internal buffers overflow in systems with a large number of IP stations the communication to IP stations has been given higher priority

New Event Handler Macros "ldb" and "prog"

Event handler macro "%lbd" for reading out local board number. Typical used for dual AMC configuration. Event handler macro "%prog(st_ind)" for reading out current program number 1->xx active on a station. Return 0 if no program active.

Private Ringing Tone in IP stations

Private ringing sequence in IP stations is now completely handled in the IP station to avoid AMC load when hundreds of IP stations is ringing in parallel.
IP stations with AUDIO event of type "Private ringing" related to the stations are still handled by AMC to obtain synchronous event state handling with the ringing tone.

Better performance of IP station PING command

Optimized IP station PING-PONG system. Equal functionality.

Mail pool increased to 2500 mails

Mail pool is increased from 1104 to 2500 mails. (Nvram state is changed)

BZ 148Incoming Call from SIP with different ringing tone

Added new nvram flag ".ex_profile.flags.trunk_alt_priv_ring". When set to "1" all calls from SIP trunks will use "UK style ringing tone".

Avoid signalling fault from analogue sub stations

From substations a short press on ID + M can be signalled as ID. When the global flag: "ID_and_IDM_to_IDC_CRM" is set, wait for 300 ms before ID is accepted.

BZ 147 Muted busy tone removed from SIP trunks

SIP stations/trunks does not get the muted busy tone (Same behaviour as PNCI system)

Start of ATLB-ATLB conversation no need for duplex resources

When starting a call between two local ATLB stations no duplex resources are allocated.
When incoming call from SIP to ATLB no duplex resources are allocated.
This will give the possibility for setting up calls in system with only ATLB12 cards.

When making a global group call and some exchanges do not receive the group call due to not available audio links, there should be a display message "Exchange Missing".

Issue 3124: AlphaNet - NAT

AlphaNet does not work if NAT traverse is used.

Log System (Syslog)


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 Drivers


Rtpdaemon

/opt/amc/bin/rtpdaemon

Rtpdaemon is a user mode service which handle the RTP audio streams. It receives control commands from the AMCD main application on a control socket (/tmp/rtpd). Rtpdaemon transfers and receives RTP packets via standard Linux network sockets. Rtpdaemon packs and unpacks RTP packets. Received packets are buffered before play out. It transfers and receives serialized audio data to the DSP via a DSP driver.

Known problems AMC hardware 8000/4

None as of now

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.

Issue 2741: Redundancy control from APC:

The redundancy control system from APC is not working (software and hardware).

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).

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.
