TN2602AP - Firmware Vintage 65 for Hardware Vintage 20+

File size - 5.74 MB (5,754 KB)
MD5 Sum - ab9c97211140539e65656a635f27d8b9

Released February 3, 2014

NOTE!!! There are now TWO different versions of TN2602AP; Hardware Vintage 0 through 19 (HV0-19) and Hardware Vintage 20 and higher (HV20+). Each hardware version requires a unique firmware file.

Note that these different hardware versions have been designed to interoperate with each other in duplicated systems. Hardware and firmware version / vintage matching is not needed.

Note also that if one attempts to download the incorrect version of FW64 to a board, the download will be rejected by the board.

This version of Firmware Vintage 65 (tn2602ap-h20-f65-sig.bin) can be applied to all HV20 and greater boards and contains the following fixes and enhancements:

  • The TN2602 did not correctly handle RTP streams in which the SSRC value changed. The TN2602 retained sequence number information from the previous SSRC. If the sequence number for the second SSRC differed significantly, the TN2602 would incorrectly consider this to be packet loss. This problem has been fixed so that the TN2602 reinitializes RTCP reception information when it sees that the SSRC value has changed (130169).
  • If an SFTP server was used to perform a firmware download or transfer a large file to the TN2602, a task sanity error could occur during the transfer. This can cause dropped calls on a SIMPLEX or duplicated ACTIVE board. Downloading the duplicated ACTIVE board may also cause an interchange and reset of the ACTIVE board. The priority of the SFTP task has been adjusted so that it no longer causes these sanity timeouts (130114).
  • It is possible for the TN2602 to go out of service if network configuration changes (e.g. link status changes, change ip-interface, etc) occur near the same time that ARP requests from the TN2602 are failing (e.g. gateway or endpoints not responding). These conditions can cause a deadlock to occur between tasks that results in call setup failures (no-way talk path) and no
    response to control messages. The board would be inserted into the system; but basic SAT tests (e.g. Test 52) would timeout and FAIL. CM logs will contain a signature of the IPSI having to retransmit downlink messages to an unresponsive board. The deadlock condition has been fixed to prevent this problem from occurring (130171).
  • Under high traffic conditions at near full capacity, the TN2602AP HW20+ board may lose internal messages in its queues that are used to support VoIP calls and other board features. The enablement of RTCP (and SVNS) tends to exacerbate the problem due to increased message generation. One symptom of this problem is calls getting stuck during call setup due to a lost response message, which leads to no-way talk path. Other symptoms may be commands or calls that fail intermittently due to lost messages. The internal message queues have been resized to prevent this problem from occurring in high traffic situations (130093).
  • Previously, when the TN2602 received an unexpected UDP packet outside of the UDP Port Range, it would silently drop the packet without any processing. This behavior could prevent the board from detecting UDP-based denial of service attacks in this port range. This problem has been fixed so that UDP packets outside of the UDP Port Range are received and counted against a denial of service attack counter that generates an alarm if necessary (130131).

This version of Firmware Vintage 65 (tn2602ap-h2-f65-sig.bin) can be applied to production vintage boards from HV0 through HV19 and contains the following fixes and enhancements:

  • The TN2602 did not correctly handle RTP streams in which the SSRC value changed. The TN2602 retained sequence number information from the previous SSRC. If the sequence number for the second SSRC differed significantly, the TN2602 would incorrectly consider this to be packet loss.

Released July 1, 2013

NOTE!!! There are now TWO different versions of TN2602AP; Hardware Vintage 0 through 19 (HV0-19) and Hardware Vintage 20 and higher (HV20+). Each hardware version requires a unique firmware file.

Note that these different hardware versions have been designed to interoperate with each other in duplicated systems. Hardware and firmware version / vintage matching is not needed.

Note also that if one attempts to download the incorrect version of FW64 to a board, the download will be rejected by the board.

This version of Firmware Vintage 64 (tn2602ap-h20-f64-sig.bin) can be applied to all HV20 and greater boards and contains the following fixes and enhancements:

  • Previously, if a call was hairpinned, the TN2602 would not report statistics for that call to the "list trace" command. This problem has been fixed and call statistics for hairpinned calls appear in the "list trace" SAT screen.
  • On the TN2602, two gratuitous ARPs are sent every 60 seconds to detect IP address conflicts and to force network equipment to update and recognize its presence. In FW64, one of these ARPs is changed to a normal ARP request to detect IP conflicts from any device that may not respond to a gratuitous ARP.
  • Previously, the terminal-parameter portion of the loss plan was being applied to re-generated DTMF signals. This could cause unnecessary loss as the re-generated DTMF signal traverses the PSTN. This loss is now only applied to inband voice signals and not to re-generated DTMF signals. The default RFC2833 DTMF level has also been increased to make it more consistent with other tones on the TDM bus. The result of these changes is that the signal level of DTMF tones being transmitted by the TN2602ap as a result of rfc2833 (rtp-payload) will now be consistently of sufficient signal level to mitigate against substantially large network loss regardless of system country code and terminal-parameter settings.
  • If the media being received by the TN2602 from the network contains a high signal level and the voice transmit setting on page 2 of "change terminal-parameters" is +7.5 or greater, then some additional distortion may be introduced in the process of the samples being sent to the TDM bus. If this distortion is noticeable, its usually a momentary scratchy sound. This distortion had been removed with this release.
  • Fixed issue with occasional failures while establishing V.32 modem sessions when modem and fax have been set to pass-through mode and the g.729 codec is used.
  • Previously the TN2602 always encoded and transmitted the RTP marker bit. This has been changed so that the TN2602 only sets RTP marker bit if silence suppression or g.729b is selected.
  • VoIP Parameter 63 (RFC2833 DTMF Signal Level Override) has been added. This
    parameter is used by services personnel to adjust the incoming or outgoing DTMF signal level.

This version of Firmware Vintage 63 (tn2602ap-h20-f63-sig.bin) can be applied to all HV20 and greater boards and contains the following fixes and enhancements:

  • Previously on hairpinned calls when an endpoint pressed a DTMF digit, the TN2602AP board could send the wrong digit in the rtp-event. This has been corrected.
  • In some rare Ethernet network configurations using HSRP and asymmetric routing, both the active and standby board could receive the same incoming rtp packets to the virtual address. If these packets were associated with a hairpinned call, the standby board could erroneously transmit these packets. This has been corrected and the standby board will not transmit any rtp packets.
  • Previously a gratuitous ARP with the virtual MAC address was only sent when a board transitioned from standby to active state. The active board would then send an ARP request for the virtual address every 60 seconds to detect IP address conflicts. Now the active board in an active/standby pair will send this gratuitous ARP every 60 seconds which serves to detect address conflicts and to also continually update network equipment with the presence of the virtual interface.
  • Previously when a board switched a call from voice mode to modem/fax/tty pass-thru mode, the rtp sequence numbers would jump by a significant number. This could be interpreted as packet loss during troubleshooting. This has been corrected.
  • Previously when a TN2602AP board was sending RFC2833 DTMF digits, the redundant packets' RTP sequence number did not increment. A voip-parameter option (68) has been made available which can activate a mode of operation that increments the sequence number of the redundant packets.
  • Previously, a T.38 interoperation issue could occur with certain third party fax servers which could result in intermittent fax failure for faxes transmitted by the fax server. This has been corrected.
  • Previously when transmitting a fax on a circuit containing a very long echo path, the Message Confirmation Report (MCF) message from the receiving fax machine might be ignored. This could result in only one page being sent. A Voip parameter option (53) has been added which can be used to resolve this issue.
  • Previously some very rare T.38 fax events, could impair some of the DSP resources on the board resulting in decreased board capacity. This has been corrected.
  • VOIP parameter 53 (T.38/fax relay echo suppression period) has been added. This parameter is used by services personnel to resolve T.38 fax relay issues that can arise with very long echo paths.
  • VOIP parameter 68 (RFC 4733/2833 Transmitter Redundancy Option) has been added. This parameter is used by services personnel to further tune the transmission of (RFC4733/RFC2833) DTMF redundant packets.

This version of Firmware Vintage 62 (tn2602ap-h20-f62-sig.bin) can be applied to all HV20 and greater boards and contains the following fixes:

  • After some rare TN2312AP/BP IPSI board clock glitch conditions on active Port Network (PN) clock and an IPSI interchange resulting in a Communication Manager (CM) warm restart of a PN, the TN2602AP board would not recover and would stay out of service until manually reset. This is now corrected and the board will recover automatically.
  • Some types of corrupted packets were discovered to cause talk-path issues and CM would log error code MEDPROPT 769. If multiple corrupted packets were received while the board was processing call traffic, CM could show the port out-of-service for an extended time. The resiliency of the TN2602AP to corrupted packets has been improved and they will no longer cause errors and ports out-of-service.
  • In some country codes, the DSP gain for talk and listen path was not always correct. This did not affect US, ETSI or TIA settings. Settings are now correct. For boards programmed to operate with the following country codes, users might hear a slight volume change. Belgium (6), France (12), Germany (13), Netherlands (5), Nordic (24), S. Africa (25), Spain (11), and UK (10).

NOTE!!! There are now TWO different versions of TN2602AP; Hardware Vintage 0 through 19 (HV0-19) and Hardware Vintage 20 and higher (HV20+). Each hardware version requires a unique firmware file.

Note that these different hardware versions have been designed to interoperate with each other in duplicated systems. Hardware and firmware version / vintage matching is not needed.

Note also that if one attempts to download the incorrect version of FW59 to a board, the download will be rejected by the board.

This version of Firmware Vintage 59 (tn2602ap-h20-f59-sig.bin) can be applied to all HV20 and greater boards and contains the following fixes:

  • It was found that in some instances, TN2602AP could incorrectly calculate round-trip delay, resulting in false round-trip delay alarms. This has been corrected.
  • Previously, TN2602AP's operating in standby mode could experience numerous MEDPROPT minor alarms. This has been corrected.
  • In certain very rare conditions, during board insertion, sometimes the DSP capacity could be reported incorrectly. This has been corrected.
  • In lab testing it was observed that with long periods of extremely high traffic coupled with certain highly unusual conditions (e.g., clock errors in the port network) that TN2602AP could go out of service and require manual intervention to recover. FW59 avoids this out of service condition.

This version of Firmware Vintage 58 (tn2602ap-h20-f58-sig.bin) can be applied
to all HV20 and greater boards and contains the following fixes:

  • *** Previously, it was reported that all TN2602AP's had to be upgraded to FW58 or greater prior to Nov 13, 2011 to avoid rejection of any new SSH sessions. This information was incorrect.

    In fact, firmware download files issued prior to May 13, 2011 have digital signatures that will expire on November 13, 2011. After the expiration date, the signed firmware download file cannot be downloaded to a target board. Note that Once the firmware is installed on a board, the board firmware will continue to operate normally after the digital signature expiration date.

    Avaya will be issuing newly signed firmware download files for many firmware releases with new digital signatures that will be valid for ~5 years. These newly signed files, once loaded onto a target board, are identical to the previous files except for the digital signature. Consequently, there is no need to re-download a board with the same vintage of firmware. ***
  • The TN2602AP echo cancellation feature has been improved to allow better modem pass-through operation.
  • Previously, in sniff traces, occasionally one could observe that the TN2602AP would send an ARP with a non-zero target MAC address. This has been corrected.
  • VoIP Parameter 67 was added to allow UDP source port validation to be disabled.

This version of Firmware Vintage 57 (tn2602ap-h20-f57-sig.bin) can be applied to all HV20 and greater boards and contains the following fixes:

  • Previously, under a severe denial of service attack containing TCP packets, the Ethernet receive buffer could fill up and not clear, causing the board to go out of service. Now, the board will recover after such events.
  • The Ethernet handling routines have been made more robust.
  • Previously, near capacity DSP usage caused by a concentration of calls using a combination of G.729a with echo cancellation, encryption, DTMF, etc., could
    result in clicking, robotic-sounding voice or, in more severe cases, one-way talk path. The processing of this traffic has been optimized to avoid these issues.
  • The digit detection routine has been enhanced to better handle mal-formed incoming digits. Previously, a single digit could be detected as two digits if the incoming digit message had DTMF tone leakage in the voice stream prior to the signaled start of the digit.
  • Previously, a stand-by TN2602AP could send RTCP messages using both physical and virtual IP address when none should be sent at all. This could cause "port-flapping" on the upstream Ethernet switch. This has been corrected.
  • Previously, with CM6.0 and later, with SIP trunk traffic, and the Early Media Feature enabled, about 8% of SIP call traffic may experience distorted ringback. Note that the distortion was subtle and did not affect voice quality. FW57 eliminates the ringback distortion.
  • Previously, TN2602AP could erroneously send a "DSP Over-Allocation" message to software. This has been corrected.
  • Previously, RSVP could send a ResvConf message with an invalid ERROR_SPEC sub-message. Now this message correctly contains the sender's IP address.

  • Previously, a small percentage of customers experienced distorted ringback on some SIP trunks. This problem only occurred with CM5.2.1 and later with SIP trunk traffic with the Early Media feature enabled. This has now been corrected.
  • In Communications Manager 6.0 systems with RSVP enabled, Service Pack 0 or later must be loaded to use FW55.
  • Previously, large conference calls (8 or more parties) could experience clicking sounds if the conference bridge connection had significant jitter. This has been corrected.
  • Previously, the IP address sent in a RTCP packet to VMM could contain incorrect information. This is now fixed.
  • Previously, hairpinned tandem IP trunk calls could have occasional call failures. This has been fixed.
  • Previously, when using the Uniphone 1140 TTY phone and TTY relay, sometimes the first character of the call was missed by the TN2602AP. FW55 corrects this issue.

  • The echo canceller has been modified to allow tuning to help eliminate double-talk (both ends "speaking" at the same time) induced corruption of DTMF
    digits. This improves IVR performace. See new VOIP parameters 18 and 19. The default settings may not yield a noticeable change.
  • The echo canceller has also been improved to reduce the echo of low level signals, such as light breathing into the handset.
  • New VOIP parameters 17, 18 and 19 have been created to allow tuning by services personnel. VOIP parameter 34 has been enhanced.

- Parameter 17: Echo Canceller Alternate Comfort Noise Option
- Parameter 18: Echo Canceller DTMF Transparency Option
- Parameter 19: Echo Canceller Heavy Double Talk Option
- Parameter 34: Modem Pass-Through Ecan Override

  • VoIP parameter 34 allows STE phones to successfully re-key.
  • Improved TTY and Special Information Tone (SIT) tone detection.
  • Previously, in certain configurations, the RTP-Event DTMF marker bit on TN2602 was not being sent. This now adheres to RFC 2833.
  • FW51 supports new Communication Manager 5.2.1 Early Media Detection feature. "Early Media" refers to the ability in SIP for a called user agent to play

NOTE: There are now TWO different versions of TN2602AP; Hardware Vintage 0 through 19 (HV0-19) and Hardware Vintage 20 and higher (HV20+). Each hardware version requires a unique firmware file.

Note that these different hardware versions have been designed to interoperate with each other in duplicated systems. Hardware and firmware version / vintage matching is not needed.

Note also that if one attempts to download the incorrect version of FW49 to a board, the download will be rejected by the board.

This version of Firmware Vintage 49 (tn2602ap-h2-f49-sig.bin) can be applied to production vintage boards from HV0 through HV19 and contains the following enhancement and fixes:

  • FW48 had an issue where it did not properly handle UDP headers with a null checksum. This could cause one-way and / or no-way talk paths.
  • TN2602 FW49 properly handles UDP headers with a null checksum. FW49 fixes a Hairpin voice path issue introduced in FW47.
  • This TN2602 firmware contains an enhancement for the MLPP feature.

This version of Firmware Vintage 48 (tn2602ap-h2-f48-sig.bin) can be applied to production vintage boards from HV0 through HV19 and contains the following enhancement and fix. G860 Media Gateway users should not use FW48 (see the Known Issue below):

  • TN2602AP FW48 supports the Communication Manager 5.2 feature Simple Voice Network Statistics (SVNS).
  • Very rarely, the "enable session" command would appear to be successful but in fact, would fail. This would cause FTP sessions to fail thus preventing firmware upgrades. This has been fixed.

Known Issue:

  • Communication Manager systems that connect to a G860 Media Gateway should NOT use TN2602AP FW48. Instead, these systems should use FW47. FW48 has an issue where it does not properly handle UDP headers with a null checksum. This can cause one-way and / or no-way talk paths. When released, TN2602 FW49 will properly handle UDP headers with a null checksum. Producing a UDP header with a null checksum is unusual, but not prohibited. Avaya is currently not aware of any other endpoints that produce null checksum UDP headers.

Note that these different hardware versions have been designed to interoperate with each other in duplicated systems. Hardware and firmware version / vintage matching is not needed.

Note also that if one attempts to download the incorrect version of FW46 to a board, the download will be rejected by the board.

This version of Firmware Vintage 46 (tn2602ap-h2-f46-sig.bin) can be applied to production vintage boards from HV0 through HV19 and contains the following fix and enhancement:

  • Previously, if both DTMF and TTY were programmed to use relay, DSP core crashes could occur which would cause dropped calls and / or one-way talk path. In this situation, CM software would log errors MEDPROPT 513 and 769-2000 . This has been corrected in FW46.
  • Previously, if a remote system terminated its transmission with a high volume level (e.g. at the end of a DTMF tone), the TN2602AP's Comfort Noise Generator (CNG) would generate a high level of comfort noise. This was perceived as a audible hiss immediately following the terminated transmission. FW46 introduces the ability to limit the maximum level of CNG via a new tunable VOIP parameter, Parameter 65 which is accessible via a TN2602AP telnet session.
  • Parameter 65: Maximum CNG Level
    value = (1 - 1000) - Change maximum CNG level to a specific value.
    value = -1 (or 0xffffffff) - DSP will use the default setting of 1000.
  • Parameter 65 detailed description:
    The comfort noise level generated by he TN2602AP is based on the estimated noise floor. Consequently, its level scales with background noise. A ceiling is imposed so that is not allowed to drift higher than a certain maximum level. In previous releases the ceiling is fixed at "1000" (approx. -30dBm) and cannot be adjusted.
  • With Fw46, the default maximum remains at 1000. Thus default operation remains the same as previous releases.
  • To change the ceiling, parameter 65 can be used to set the maximum to a lower value. For example a value of 100 is approx -50dBm, which is a reasonable compromise that provides adequate comfort noise, yet not so loud to be disconcerting. If hiss is an issue, we recommend initially setting parameter 65 to a value of 100. A low non-zero value is preferred as a value of zero essentially shuts comfort noise off altogether.
  • Example TN2602AP telnet session commands to override the CNG ceiling with a new (lower) value of 100:
    setVoipParam 65, 100 (prepare to override default CNG ceiling with the value 100)
    sendVoipParams (send new parameter to the DSPs, thus activating new ceiling for new calls)
    saveVoipParams (saves the programmed parameter to non-volatile memory)

Released August 11, 2008

Firmware Vintage 41 can be applied to all production vintage boards (HV2, HV4 through HV8) and contains the following enhancements and fixes:

  • Firmware Vintage 41 combines the new Communication Manager 5.1 syslogging feature introduced in FW 40 with the fixes introduced in FW35 (listed below).
  • This firmware has enhanced DTMF detection that should reduce spurious touch-tone digits (talk-off) during active calls.
  • Previously, TTY calls could cause DSP resets, potentially causing one-way or no-way talk paths. This has been corrected
  • Previously, when performing relay of TTY and/or DTMF tones, a jitter buffer overflow condition could occur. This could cause gaps in tones which could cause endpoints to detect repeated digits.
  • Previously, when a H.323 phone and SIP trunk are in a call and the call is hairpinned through a crossfire board, an initial DTMF signaling tone (such as the first digit of a password for a conference bridge or voice mail system) could be dropped. All subsequent DTMF tones were passed correctly. Now, all digits are sent correctly.

Released June 30, 2008

This release applies to all production vintage boards (HV2, HV4 to HV8).

Firmware Vintage 40 supports the Communication Manager 5.1 syslogging feature.

The intent of the syslogging feature is to provide increased capability to debug network problems and to support a centralized server as a collection point for ease of access and management of historical log data.

FV40 also corrects the following problem:

  • Previously, when a H.323 phone and SIP trunk are in a call and the call is hairpinned through a crossfire board, an initial DTMF signaling tone (such as the first digit of a password for a conference bridge or voice mail system) could be dropped. All subsequent DTMF tones were passed correctly. Now, all digits are sent correctly.

Note that there will be two loads of future firmware to be released for TN2602AP:

  • FV35, which is scheduled be released mid-July, will contain a number of field fixes. However, FV35 does NOT contain the Communication Manager 5.1 syslog feature. The field fixes include improved DTMF detection - which will reduce or eliminate spurious tones inserted into the voice path - and the elimination of rare DSP resets induced by TTY calls.
  • FV41, scheduled for mid-August, will contain the field fixes contained in FV35 plus the Communication Manager 5.1 syslog feature.
  • FV40 is recommended for those customers that require the fix included in FV40, or for Communication Manager 5.1 customers who wish to implement the syslog feature at this time. All other customers are encouraged to implement FV35 or FV41 when they become available.

Released April 7, 2008

This release applies to all production vintage boards (HV2, HV4 to HV8).

FW 34 contains the following fixes and enhancements relative to FW 33:

  • FW34 limits the output amplitude of DTMF relay tones to -12dBm as the default. This prevents receiver saturation with DTMF relay with other non-Avaya gateways that may use a louder RFC2833 volume level when relaying digits. This change helps ensure accurate reception of relayed DTMF tones in those environments. A VoIP parameter has been added to allow programmability for this override as well.
  • FW34 corrects a problem introduced in FW33 that in some instances could cause inter-digit timing between regenerated DTMF relay tones to be less than 40 milliseconds, but only when the original inter-digit timing of the detected signal is less than 80 milliseconds. In certain call routing configurations, this could occasionally lead to DTMF detection problems on the PSTN, resulting in call completion failures.
  • FW34 contains an updated tone detection algorithm which improves overall DTMF detection performance
  • FW34 adds AES/AEA encryption support for fax-relay and T.38.
  • FW34 disables TTY detection if the far-end does not support TTY.
  • Additional VoIP parameters can now be tuned to improve STU phone operation.

Released December 3, 2007

This release applies to all production vintage boards (HV2, HV4 to HV8).

FW 33 contains the following fixes and enhancements relative to FW 32:

  • TN2602AP FW32 introduced a DTMF digit relay problem that can result in DSP buffer exhaustion and DSP resets. This can lead to one-way, no-way, and bridged talk paths. This problem has been corrected.
  • DTMF relay operation has been improved by making the RTP-Payload transmission more robust. Previously, if the DTMF relay string was missing an "end-of-digit" indication, subsequent digits would not be transmitted. Also, individual digits may have been dropped.
  • DTMF digit detection has been enhanced to better accommodate poor quality DTMF digits. Frequency tolerances and signal-to-noise ratio requirements have been modified.
  • Previously, a flood of ICMP redirect messages could cause DSP and board resets. This could result in one-way and no-way talk paths and dropped calls. This has been corrected.
  • TN2602AP IP network jitter tolerance has been improved, resulting in better voice quality at jitter levels above 200 ms.
  • Previously, large delay changes in an IP network could cause one-way talk path. This has been corrected.
  • Hairpinning operation has been improved. Previously, tandem IP trunk calls that hairpinned on a TN2602AP could have no talk path and might not free all resources, potentially resulting in one-way and no-way talk paths.
  • Previously, TN2602AP did not properly decode and play g.729 rtp streams if the padding bit was set and padding was included in the rtp packet. This has been corrected.
  • A change has been made (an index was added to the end of the RTCP string) to enhance compliance with the RTCP protocol.

File size - 5.03 MB (5,279,524 bytes)
MD5 Sum - e36e4bc00c14161ad8a9cb2951ed0e90

Released September 7, 2007

This release applies to all production vintage boards (HV2, HV4 to HV8).

FW 32 contains the following fixes and enhancements relative to FW 31:

  • FW 32 corrects a problem with G.729/G.729A codec operation that could cause DSP resets when encryption and silence suppression is used with 97xx type phones.

  • Hairpinning operation has been improved thus preventing boards from sending UDP packets to unreachable ports. This caused resources to be consumed and not released.

  • Previously, an ARP flood Denial of Service (DoS) attack could cause the board to reset. Now, the board stays in service and recovers cleanly from the DoS attack.

  • Occasionally, when a call is redirected, e.g. covered to Intuity Audix, a single click might be heard at the moment the call is redirected. This has been corrected.

  • DTMF digit transmission has been modified to make it more robust.

  • Improved operation with Fax Relay and T.38 Fax

  • In duplicated TN2602AP applications, the stand-by board will recover quicker from a DSP reset.

  • Improved VMM statistics.

Released May 7, 2007

This release applies to all production vintage boards (HV2, HV4 to HV8).

FW 31 contains the following fixes and enhancements relative to FW 30:

  • Previously, with duplicated TN2602AP boards, when hairpinning and RSVP were both enabled, some DSP channels could lock-up causing one-way talk path. This has been corrected.

  • Jitter management has been improved. This results in better voice quality in networks with high levels of jitter.

  • Jitter and packet loss reporting has been improved.

  • T.38 Fax operation with some fax machines has been improved.

  • Previously, TN2602AP fax-relay / T.38 operations could fail if a terminal generated short or no CED tone. This would caused fax time-out or failures. This has been improved.

Released November 9, 2006

FW 25 contains the following fixes and enhancements relative to FW 24:

  • Modem and Fax operations have been improved:

Echo Cancellation defaults to "disabled" on modem pass-through calls.

Previously, if AES encryption was enabled and the Modem codec was set for pass-through or relay, fax calls (pass-through or relay) would fail to connect. This has been corrected.

Fax operation with AES encryption has been improved.

  • Modem tone detection has been enhanced to prevent voice talk-off to modem mode.
  • Previously, a traceroute timeout could cause duplicated TN2602AP configurations to interchange. Also, TN2602AP sometimes would not respond to pings or traceroute packets from other equipment. These issues have been corrected.
  • Now, "list trace" commands report accurate information for FAX/Modem pass-thru calls.
  • Jitter and packet loss reporting for Fax/Modem/TTY calls has been improved.
  • Previously, systems using Fax, Modem, and/or TTY pass-through needed to have the same redundancy values for all three modes. This is no longer required.
  • Previously, some third-party DTMF relay could cause DSP failures. This has been corrected.
  • Round Trip Time (RTT) reporting to VMM has been improved.
  • Debugging capabilities for services personnel has been enhanced to capture information on fax events and DSP resets.

TN2602AP - Firmware Vintage 12 

Vintage 12

Released March 9, 2006

TN2602AP Firmware Vintage 12 (FW12) is HIGHLY recommended for all TN2602AP in simplex or load balancing configurations. FW12 does NOT support the TN2602AP bearer duplication feature introduced in CM3.1!

FW12 contains the following fixes and enhancements:

  • FW12 corrects problems that could cause boards to temporarily go out of service. Formerly, these problems caused MEDPROPT 769 2000 and IPMEDPRO 513 4358 errors to be logged.
  • Firmware level parameters have been added to allow services personnel to control some settings. E.G. now, comfort noise generation (CNG) can be disabled.
  • Previously, some calls on IP stations had static-on-hold problems.
  • Corrected echo canceller operation that sometimes caused the remote speaker volume level to drop.
  • Previously, when using G729 codecs, very high levels of fax-relay traffic could cause DSP resets. This would result in failed faxes, one-way, and no-way talk paths.
  • Improved operation during a denial-of-service (DoS) attack.
  • Improved DTMF operation with Cisco SIP phones.

TN2602AP - Firmware Vintage 9 

Vintage 9

Released November 17, 2005

TN2602AP FV9 is HIGHLY recommended for ALL systems.

The following issues have been corrected:

  • Previously, TN2602AP might not properly reconfigure itself in response to certain packet bus failures, potentially causing call processing outages. This has been corrected.
  • RTCP reporting, used by Avaya VoIP Monitoring Manager -- aka VMON / VMM, no longer causes one-way and no-way talk paths. Customers should upgrade all their TN2602APs to FV9 before enabling RTCP reporting.
  • Hairpinning now works properly.
  • When TN2602AP was loaded to near capacity using G.729 encoding, voice quality could degrade. FV9 corrects this condition.
  • TN2602AP error reporting has been improved.

Tips for Searching Avaya Support


A good query consists of three things:

 Enclose exact words or phrases in double quotes. Include plus (+) to require words, minus (--) to exclude words, and OR between words. i.e. forwarding OR coverage + "all calls"-- remote

 

Don't include "special" characters in your search (i.e. &, <, >, *, $, / ,\, ....)

 

The more exact the phrases are to the actual title or string of text in a document, the better the results
