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.

OL-6670-01
Cisco IOS Software Compatibility
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
Caveats for Release 10.9
Resolved 10.9 Caveats
•
CSCsg66906: SPE crashes when modemcap is applied
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.
•
CSCsh25948: NextPort connects at a different modulation than specified in s64
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.
•
CSCsi47380: NextPort not handling non-zero CC field in RTP header correctly
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
•
CSCse82173: Invalid DTMF relay sent from Cisco AS5850 to PSTN
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.
•
CSCsf08167: Noise heard when barging into a prompt
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.

NextPort SPE Firmware Caveats
•
CSCsf09206: Clicking noise heard at beginning of VXML script
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
•
CSCeg00452: Slip call does not work with NP after upgrade to Cisco IOS 12.3(9)
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.
•
CSCsa88459: T.38 may fail with certain fax machines due to missing EOLs
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.
•
CSCsa82291: Digit redundancy pkts may be interrupted with voice packets
Symptoms: Not all DTMF digits are being decoded correctly by ASR server.
Workaround: There is no workaround.
•
CSCsd49012: Import CSM Protocol Interop Failure with MNP Fix to CSMv6
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.
•
CSCsc51697: Modem CSR and abnormal disconnect rate too high
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.

NextPort SPE Firmware Caveats
•
CSCse01122: NextPort does not reply with OK in the first try after using +++ and ath
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.
•
CSCse31695: NextPort ignores s7 and s37 register settings
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
•
CSCsb21942: Extend T.38 TX level range
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.

Workaround: There is no workaround.
•
CSCef88319: DTMF tones being heard when DTMF relay is configured
Symptoms: DTMF tones being heard in the RTP stream when DTMF relay is configured.
Workaround: There is no workaround.
•
CSCsa57457: Cisco AS5400 using fax relay is corrupting the t30 DCN message
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.
•
CSCsa51298: ISDN data call fails over Clear channels on MGCP Controlled TGW
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.
•
CSCeh14211: Slip with duplicate packets
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.
•
CSCsa95120: Intermittent one-way voice from SIP to PSTN in the Cisco AS5400
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.
•
CSCsb39054: RTP Comfort Noise (CN) frame being sent when VAD disabled
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.
•
CSCsb00457: Nextport fails to dial out with dial modifier and modemcap applied
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.

NextPort SPE Firmware Caveats
Workaround: There is no workaround.
•
CSCsa91021: NextPort does not prefix CONNECT result code with CR LF
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:
– The ATDT dialstring command on the dialing terminal may be overwritten.
– An application expecting the CONNECT result code to be prefixed with <CR><LF> may fail
to recognize the CONNECT
– An application using Windows TAPI may fail to recognize the vendor-specific CONNECT
information (speed, compression, etc.)
Workaround: Modify the dialing application (or TAPI .inf file) so that it does not look for the
<CR><LF> sequence prior to the CONNECT.
•
CSCsc09596: Voice dropouts with G729abr8 codec
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.
•
CSCsc11992: MNP may drop outgoing data
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.
•
CSCsc13646: Infinite Session Hang in EC mode - all modulations - No EC Timer Expiry
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.

CSCeg00452: Slip does not work with nextport after upgrade to 12.3(9) IOS image
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:
– async mode interactive on the Group-Async interface
– autoselect slip on the TTY lines
Workaround: Give the destination host to which Async SLIP dialup clients send IP traffic an IP
address which does not contain 192.
•
CSCeg69837: FAX passthrough fails after few days - NSE changed
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.

•
CSCea86206: NextPort connect at lower speeds than MICA for specific line condition
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.
•
CSCeb61464: Reduced throughput with ARQ blocksize <= 128
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.
•
CSCec62153: VAD threshold with G729r8 packets is incorrect
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.
•
CSCee02179: Nextport unable to trainup with USR client under certain line condition
Symptoms: Under certain pots line conditions, USR client modems are unable to trainup with
NextPort modems.

An emergency is either a condition in which a system is under active attack or a condition for which
a severe and urgent security vulnerability should be reported. All other conditions are considered
nonemergencies.
•
For nonemergencies — [email protected]
In an emergency, you can also reach PSIRT by telephone:

1 877 228-7302
•
1 408 525-6532
We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to
encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been
encrypted with PGP versions 2.x through 9.x.
Never use a revoked encryption key or an expired encryption key. The correct public key to use in your
correspondence with PSIRT is the one linked in the Contact Summary section of the Security
Vulnerability Policy page at this URL:

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (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:
http://www.cisco.com/techsupport/servicerequest
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 2447
For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
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.
