New Features In Version 10.x.x SPE Firmware
This section contains feature information for NextPort SPE firmware version 10.x.x.
NextPort Dual-Filter G.168 Echo Canceller
Dual-filter G.168 echo canceller capability has been added to the CSMV6 dial feature card (DFC) for NextPort platforms. The NextPort dual-filter G.168 echo canceller (EC) improves voice quality in VoIP connections by providing relatively less residual echo leakage, better non-linear processing (NLP) timing, less clipping, and better comfort noise generation (CNG) in most environments.
The dual-filter G.168 echo canceller features two concurrently operating adaptive filters (which control echo tail coverage) and two double-talk detection functions. In addition, the comfort noise model uses "Hoth noise" spectrum shaping to better replicate the true noise spectrum.
The NextPort dual-filter G.168 echo canceller uses the same voice-tuning (VCtune) interface for configuring voicecap parameters as the Cisco-proprietary G.164 echo canceller. Adjusting the dual-filter echo canceller is carried out by using a voicecap or by using the Cisco IOS command-line interface (CLI) during configuration.
For more information about the dual-filter G.168 echo canceller, see the following documents:

NextPort SPE Firmware Caveats
This section describes known problems and resolved caveats with NextPort firmware and NextPort SPE firmware:
Caveats for Release 10.9
Resolved 10.9 Caveats
•
Symptom: SPE crashes when modemcap applied to modems in a Cisco AS5400.
Condition: This was found on a Cisco AS5400 running Cisco IOS12.4.7b image.
Workaround: There is no workaround.
•
Symptom: NextPort seems to connect with a different modulation than specified in s64 register setting, by using the S64 register, NextPort is forced to try ONLY the standard specified in S64. The only exception is if S64 is set to 1(V.90) where, due to the V.8 specification, a fallback to V.34 is allowed.
Conditions: Dailout using NextPort with a modemcap that has s64 set.
Workaround: There is no workaround other than not using s64 in the modemcap and having the default automode enabled.
•
Symptom: NextPort does not handle non-zero CC field in RTP header correctly.
Conditions: Non-zero values in the CC field of the RTP header.
Workaround: There is no workaround.
Caveats for Release 10.8
Resolved 10.8 Caveats
•
Symptoms: The Cisco AS5850 is sending the incorrect duration for DTMF digit relay to the PSTN. Unable to measure DTMF digit relay locally on the Cisco AS5850.
Conditions: Trying to measure duration played out by 5850 towards PSTN side. The setup is as follows:
[A] ----{ip}----- 5850 ----{tdm}--- [B]The Cisco 5850 is controlled by a CA using MGCP.
[A] sends 2833 telephony events with Event Duration of 800 for 3 RTP packets with 'End of Event' (which should be equivalent to 100msec). At [B], the customer put on an analyzer and measured digit duration to be around 50-55msec.
Workaround: There is no workaround.
•
Symptoms: A sound is heard when barging into vxml prompt by saying the option.
Conditions: This only seems to happen while barging in with voice not DTMF.
Workaround: There is no workaround.
•
Symptoms: A clicking sound is heard at the beginning of the vxml script on the Cisco AS5400.
Conditions: Calls are not lost and clicking sound does not repeat later in the call.
Workaround: There is no workaround.
Caveats for Release 10.7
Resolved 10.7 Caveats
•
Symptoms: The customer is running Slip on POS modem:
CPOS (POS modem) <---->PSTN <---> AS5350 <----> CXI (POS server)
The connection ends because the CPOS sent a packet that never arrived at the CXI server. Because the CPOS does not retry in this case, it times out when the CXI server does not respond (since it did not get the packet) and ends the connection.
Workaround: This problem is not seen on the Cisco 3725 running Cisco MICA. Use non-NextPort-based platform like the Cisco 3725.
•
Symptoms: T.38 fax may fail with certain third party fax servers communicating with certain client fax machines due to missing EOLs.
Conditions: This occurs only when third party fax servers and certain client fax machines with non-ECM calls are used.
Workaround: Use ECM for fax calls.
•
Symptoms: Not all DTMF digits are being decoded correctly by ASR server.
Workaround: There is no workaround.
•
Symptoms: Layer 2 error control protocol MNP window size failure requires Mindspeed fix from CSMv12 to be ported into CSMv6. WIthout the protocol correction, NextPort is unable to interoperate with client transactions using MNP4.
Conditions: This problem is experienced with legacy MNP client Ryder16. Mindspeed has ported an initial correction into the v6 which allows the protocol to establish and exchange data but if at any time there is an abnormal disconnect the only recovery mechanism is to reload the SPE.
At the request of Mindspeed, a subsequent defect for the protocol failures will be chained from this defect to address each aspect individually. See CSCsd49012.
Workaround: Replace the Cisco AS5350 and Cisco AS5400s with a Cisco 2811 with CSMv12. No NextPort workaround exists.
•
Symptoms: Modem connection performance needs to be improved including call success rate and abnormal disconnection rate with some particular client modems.
Workaround: There is no workaround.
•
Symptoms: NextPort does not reply with "OK" in the first try after using the +++ and ath commands.
Conditions: After entering the ath command, there is initially no modem response to additional commands. Entering the additional command a second works.
Workaround: There is no workaround.
•
Symptoms: If the answering modem (or called modem) does not answer the call (go OFFHOOK), the calling Nextport modem will continue to ring endlessly and will not terminate the call with a "NO ANSWER."
Conditions: Access server platforms with NextPort modem (Cisco AS5350, Cisco AS5400, and Cisco AS5850) dialing a modem that does not answer will never time out. This problem is seen in Cisco IOS software release 12.4(7a) with SPE version np.0.10.3.1.spe and np.0.10.6.0.spe.
For example, if you enter ats7=12s37=12dt1234567890, the request will never time out if the called modem does not answer the call (go offhook).
Workaround: There is no workaround
•
Symptoms: Faxes are not coming through customer networks because T.38 levels change throughout the Cisco AS5400 Gateways. Calls enter from the PSTN at the correct signal levels and exit to the PSTN with the incorrect levels.
Conditions: This only happens to fax calls and looks like the gateways are changing the level without any configuration to do so. By using the Telecom Faxright service it is possible to get a report on the Signal levels and all T.38 Fax calls are reported to have a level of -10.5dBm. The correct level should be about -17.5dBm. It has been confirmed that the correct levels are seen on the incoming call but leave with the incorrect levels. Voice calls are fine and a test 2khz tone was used to verify the levels are not being modified by the gateways. When using the test tone and adjusting the output attenuation the levels are adjusted on the output side which is correct. This problem is only experienced with T.38 Fax calls with a level of -10.5dBm and can be replicated every time with a fax test. Could there be a problem in the IOS code that limits or sets the Signal Level to -10.5dBm and not allowing it to be the level that it receives? The signal level should be -17.5dbm. Hardware is Cisco AS5400s with E1 SS7 circuits to the Telecom (carrier). The Cisco IOS software version that is running on these access servers is 12.3(8)T8.
Workaround: There is no workaround.
Open 10.7 Caveats
There are no open caveats in this release.
Caveats for Release 10.6
Resolved 10.6 Caveats
•
Symptoms: Modem calls are dropped and the following error message is seen:
%NP_SSM-3-RUNTIME_ERROR: SSM(6/64): Session Runtime Error Code = 6, RecoveryAction = 2.Conditions: This error is seen on Cisco AS5400s running the Cisco IOS Release 12.3 (20040913:160920) software image with SPE version 8.11.1.
Workaround: There is no workaround.
•
Symptoms: DTMF tones being heard in the RTP stream when DTMF relay is configured.
Workaround: There is no workaround.
•
Symptoms: Fax relay t30 DCN message is being corrupted on egress from AS5400. This stops certain faxes and fax severs from working correctly.
Conditions: This problem occurs during fax relay between a Cisco 3745 and a Cisco AS5400.
Workaround: There is no workaround.
•
Symptoms: Calls that require a clear channel codec on a Cisco Voice Gateway controlled with MGCP by a Call Agent (MGC) may experience user failure.
Conditions: This problem occurs only to calls that require the clear channel codec.
Workaround: There is no workaround.
•
Symptoms: Previous SLIP calling client TFTP requests get dumped from a Cisco AS5350 when the new SLIP calling client is connected to the same async interface.
Workaround: After each file transfer, enter the clear spe command.
•
Symptoms: One-way voice on from SIP to PSTN (the PSTN user cannot hear the SIP user) happens randomly for calls going through a Cisco AS5400 gateway; the call is established properly and both parties can hear each other, but eventually one-way voice periods of 10-20 seconds occur from the IP user to the PSTN user.
Conditions: No packets are lost in the de-jitter buffer during faulty calls.
Workaround: There is no workaround.
•
Symptoms: In the Session Description Protocol (SDP) of an "Invite" message, there is no advertisement of payload type 13 or 19 for comfort noise. The media information in the SIP 200 OK shows that no comfort noise was negotiated. However, in the RTP media stream, comfort noise packets are being propagated.
Conditions: This problem occurs on a Cisco AS5400HPX and VAD is disabled on the VoIP dial peers.
Workaround: There is no workaround.
•
Symptoms: Nextport modems do not connect to V.22bis/2400bps modems when in originate mode. The Nextport state will go to connect, then link, and then it will disconnect.
Conditions: Setting up s29=4 and s64=6 to force it to do V.22bis only, turning off EC (s23=s24=0) and setting max or minimum connect speed to 2400 bps (s30=s31=2400) has no effect.
Workaround: There is no workaround.
•
Symptoms: When dialing out using a NextPort modem, the CONNECT result code is not prefixed with a <CR><LF> sequence. As a result, the following occurs:
–
–
–
Workaround: Modify the dialing application (or TAPI .inf file) so that it does not look for the <CR><LF> sequence prior to the CONNECT.
•
Symptoms: When using the g729abr8 codec with Voice Activity Detection (VAD), users may experience an approximate -10dB decrease in VAD capability possibly triggering Comfort Noise Generation (CNG) where voice activity should be present.
Conditions: This problem occurs in voice gateway to voice gateway environments using G729abr8 codecs in their dial peers. This is specifically present in the 0.10.4.0 & 0.10.5.0 SPE code versions.
Workaround: There is no workaround.
•
Symptoms: Nextport modem does not relay a second packet over MNP to an INGENICO ETP if this packet arrives more than one second after the first one.
Workaround: Use a Cisco Mica-based platform instead.
•
Symptoms: NextPort hangs in Error Control Negotiation and never progresses to Steady State when a non error control client tries to connect to Nextport with error control enabled. It is likely that Nextport's timer for error control fails to expire.
Conditions: This problem occurs when a client with no EC forces a connection with Nextport with EC-enabled.
Workaround: There is no workaround.
Caveats for Release 10.4.1
•
Resolved 10.4.1 Caveats - NextPort SPE Firmware
•
Symptoms: Issue was found to be due to race condition between ISDN call-teardown and DCN message being sent. This change allows the DCN message latency to be reduced via an API.
Conditions: Fax relay between 3745 and AS5400. Certain faxes fail.
Workaround: There is no workaround.
Caveats for Release 10.4.0
•
Resolved 10.4.0 Caveats - NextPort SPE Firmware
•
Symptoms: COT test fails with loopback and contest modes in 12.3(9.8)T.
Workaround: There is no workaround.
•
Symptoms: A Cisco AS5400 discards SLIP traffic received from an Async dialup client when the IP destination address contains 192.
Conditions: The Cisco AS5400 is configured for Async SLIP dial-in. For example:
–
–
Workaround: Give the destination host to which Async SLIP dialup clients send IP traffic an IP address which does not contain 192.
•
Symptoms: When the Cisco 5350 voice gateway is receiving faxes from PSTN and is connecting to an ATA 186, the fax transmission may start failing after a few days.
Conditions: This was reported on a Cisco 5350 running Cisco IOS Release 12.3(11)T The values sent by the Cisco 5350 when the fax does not work is an NSE value different from 100.
Workaround: Implement voice class and assign a higher priority to g729 and the next highest priority to g711.
•
Symptoms: Cisco AS5400 running Cisco IOS 123-4T6 might have voice quality issue (noise) with Cisco IP (SIP) phones 7960.
Workaround: There is no workaround.
•
Symptoms: When upgrading to SPE version 10.2.2, the following messages are seen from time to time:
Jan 3 17:30:26.882: %NP_EST-6-RUNTIME_ERR_NTF: (NP address 4/0/0/5), SessionID=0x01D0, Error=INVALID_SPE_RESPONSE, Data format=ASCII, Data len=73, Data=GWSERV_Workaround: There is no workaround.
•
Symptoms: Testing w/ multiple fax passthrough (FPT) calls on one SPE shows degraded fax success rates when compared to previous code releases.
Conditions: Basic testing info:
OS (for all tests recorded here):12.3(20040722:195955) [daqi-8_11_2_rel 100]. Test run using QSA, generate 6 FPT calls at 14400, ECM, 10 iterations
0.8.8.1 100% CSR, 100% FSR0.8.9.1 100% CSR 100% FSR0.8.10.0 100% CSR 80% FSR 9 fallbacks to 12000, 6 successful0.8.11.1 100% CSR 81% FSR- 12 fallbacks to 12000, 5 successful, 1 fallback to 96000.8.11.2 100% CSR 77% FSR 10 fallbacks to 12000, 3 successful, 3 fallbacks to 9600-0 successfulWorkaround: Drop back to earlier code release which did not see problem. Keep in mind that the problem was seen only w/ 6 FPT calls running on one SPE, which has a relatively low chance of occurrence outside of a testing environment.
•
Symptoms: Incorrect Signal Levels are shown in dBm shown in the show spe fax active x y command output.
Conditions: This is seen on Cisco AS5400, Cisco AS5850, and Cisco AS5350 using T37 onramp.
Workaround: Use GLCOMM or other test equipment to measure
•
Symptoms: A NextPort modem is unable to train in Bell103 modulation when dialing out.
Workaround: Downgrade to NextPort 7.11 firmware. Use the following modem configuration
s64=11s15=0s16=0s17=0s21=0s22=0s23=0s24=0•
Symptoms: This issue is due to the support of Bell103 first introduced in 8.11.1.SPE. We added a bit to support this feature, but broken No Circuit Tone in China 1's and Japan SIT tone. The root cause has been identified. Need open this DDTS to track the fix. This likely will not affect US users.
Conditions: SPE firmware versions 8.11.1 to 10.2.2 will have this issue.
Workaround: There is no workaround.
Caveats for Release 10.3.1
This section describes known problems and resolved caveats with NextPort Firmware and NextPort SPE firmware.
•
Resolved 10.3.1 Caveats - NextPort SPE Firmware
•
Symptoms: The Cisco AS5350, Cisco AS5400, and Cisco AS5850 gateways are unable to generate the first several DTMF digits in DTMF relay with g723ar53, g723ar63, g723r53, or g723r63 codecs configured.
Conditions: This occurs with NextPort firmware version 4.24.10.3 (version obtained with show next mm) or SPE firmware version 10.3 (version obtained with show spe ver) with g723ar53, g723ar63, g723r53, or g723r63 codec configured and DTMF relay is used.
Workaround: Use an SPE version other than 10.3. SPE firmware can be downloaded from the following link: http://www.cisco.com/cgi-bin/tablebuild.pl/nextport-spe
•
Symptoms: Cisco AS5400 gateways are seeing a higher than normal amount of voice call failures (No path confirm [first & subsq]) while testing in E1R2.
Conditions: This occurs on the Cisco AS5400 with NextPort firmware version 4.24.10.3 (version obtained with show next mm) or SPE firmware version 10.3 (version obtained with show spe ver) with mixed codecs, VAD on or off, E1 with R2-digital or R2-compelled.
Workaround: Use an SPE version other than 10.3. SPE firmware can be downloaded from the following link: http://www.cisco.com/cgi-bin/tablebuild.pl/nextport-spe
•
Symptoms: When client modems dial into a Cisco AS5400 via certain dual-codec circuit paths, the modems may train at a significantly lower data rate than is seen when a Cisco AS5300 is used.
Workaround: There is no workaround.
•
Symptoms: Need to change the default for selective reject to enabled.
Conditions: This is related to the original addition of the selective reject code, which had the default setting as disabled. This was fixed in CSCdx03968. On a Cisco AS5xxx with nextport technology, reduced throughput may observed in the modem service with certain client modems.
Workaround: There is no workaround.
•
Symptoms: The default VAD threshold for a call should be at -38dbm. However, while running with codec G729r8 on a VoIP session, the VAD seems to disengage at a value lower than -38dbm.
Conditions: The bandwidth used for the session may be higher than typically expected with VAD enabled.
Workaround: The impact seems to be minimized when using the G729br codec instead.
•
Symptoms: Under certain pots line conditions, USR client modems are unable to trainup with NextPort modems.
Conditions: This issue is strictly due to the combination of certain PBX POTS lines and old USR client modem.
Workaround: Change the POTS line or change the USR modem to the latest version.
•
Symptoms: Onramp store and forward fax calls are failing in 12.3(7)T and the same calls are working in 12.2(15)XB5. Single page fax call shows up at the mail server but the fax machine shows transmission error. For multiple page fax calls, only the first page goes through.
Workaround: There is no workaround.
•
Symptoms: Mis-detection of V.21 messages after T.4 high speed data transfer with low signal from line.
Workaround: Apply a 6db boost to the receiving signal.
•
Symptoms: 7001 session abort notices with auto recovery are seen once a week.
Workaround: There is no workaround.
•
Symptoms: COT test fails with loopback and contest modes in 12.3(9.8)T
Workaround: There is no workaround.
•
Symptoms: In certain IVR environments, NextPort DSPs may pause playout for excessive periods of time.
Workaround: There is no workaround.

(S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411
Australia: 1 800 805 227
EMEA: +32 2 704 55 55
USA: 1 800 553 2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
