Note You can find the most current Cisco IOS documentation on Cisco Connection Online
(CCO). These electronic documents may contain updates and modification made after the
hardcopy documents were printed.
These release notes for the Cisco MC3810 multiservice access concentrator describe the enhancements provided in Cisco IOS Release 12.1(5)T. These release notes are updated as necessary.
For a list of software caveats that apply to Cisco IOS Release 12.1(5)T, see Caveats for Cisco I OS R elease 12.1 T that accompanies these release notes. The caveats document is updated for every maintenance release and is located on CCO and the Documentation CD-ROM.
The Cisco MC3810 multiservice access concentrator is fully supported by Cisco IOS software for multiprotocol routing, bridging, and Systems Network Architecture (SNA). As part of an enterprise backbone or as customer premises equipment (CPE) to serve provider-managed network services, the Cisco MC3810 reduces operating costs and complexity, and increases network throughput and performance.
The Cisco MC3810 provides a complete file system for software images, message files, and reports. The standard Flash memory size is 8 MB, and a 16-MB upgrade option is available. The 16-MB version can hold two code images simultaneously for fail-safe upgrades.
Management and configuration of the Cisco MC3810 should be familiar to the Cisco IOS user and compatible with existing management systems. As such, it provides a superset of the Cisco command-line interface (CLI). The Cisco MC3810 can be managed by standard Cisco management platforms and facilities such as CiscoView and the native remote log-in facilities provided by Telnet and rlogin. Three types of configuration interfaces are provided:
Cisco CLI
HTTP-based configuration server
SNMP-based Management Information Base (MIB)
The HTTP-based interface allows configuration from any web browser such as Netscape Navigator or Microsoft Explorer. The SNMP MIB allows management of the Cisco MC3810 from SNMP managers (for example, HP OpenView).
For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1(5)T, see the "New and Changed Information" section on page 42 and the "Related Documentation" section on page 56.

Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Network Layer Encryption (40-bit or Export Controlled 56-bit DES)
The following is a list of the new hardware and software features supported by the Cisco MC3810 for Cisco IOS Release 12.1(5)T.
New Hardware Features in Release 12.1(5)T
The following new hardware feature is supported by the Cisco MC3810 in Cisco IOS Release 12.1(5)T.
MC3810-BVM4-NT/TE
The ISDN BRI Voice Module (BVM4-NT/TE) for the Cisco MC3810 enables Cisco IOS software to replicate the public switched network interface to a PBX that is compatible with European Telecommunications Standards Institute (ETSI) NET3 and QSIG switch types.
New Hardware Features in Release 12.1(3a)T1
There are no new hardware features supported by the Cisco MC3810 in Cisco IOS Release 12.1(3a)T1.
New Hardware Features in Release 12.1(2)T
The following new hardware feature is supported by the Cisco MC3810 in Cisco IOS Release 12.1(2)T.
High-Performance Compression Module
The high-performance compression module (HCM) enables the Cisco MC3810 to provide greater density for voice calls. There are two types of high-performance compression modules, the HCM2 and the HCM6, and each provides voice compression according to the codec specified when the Cisco MC3810 is configured. Table 7 shows the number of voice channels each type of compression module can support.

New Software Features in Release 12.1(5)T
The following new software features are supported by the Cisco MC3810 in Cisco IOS Release 12.1(5)T.
AutoInstall Using DHCP for LAN Interfaces
The AutoInstall Using DHCP for LAN Interfaces feature replaces the use of the Bootstrap Protocol (BOOTP) with the use of the Dynamic Host Configuration Protocol (DHCP) for Cisco IOS AutoInstall over LAN interfaces. AutoInstall is a Cisco IOS software feature which provides for the configuration of a new routing device automatically when the device is initialized. DHCP (defined in RFC 2131) is based on the Bootstrap Protocol, which provides the framework for passing configuration information to hosts on a TCP/IP network. DHCP adds the capability of automatic allocation of reusable network addresses and additional configuration options. In Cisco IOS release 12.1(5)T, the IP address procurement phase of the AutoInstall process is now accomplished using DHCP for Ethernet, Token Ring, and FDDI interfaces. Prior to this release, IP addresses for LAN interfaces were obtained using BOOTP during the AutoInstall process. The AutoInstall Using DHCP for LAN Interfaces feature also allows the routing device to recognize IP address allocation messages coming from regular BOOTP servers, providing a seamless transition for those devices already using BOOTP servers for AutoInstall. Additionally, this feature allows for the uploading of configuration files using unicast TFTP. For further details, please see the following document: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121t/121t5/dt_dhcpa.htm
Closed User Group Selection Facility Suppress Option
A closed user group (CUG) selection facility is a specific encoding element that allows a destination data terminal equipment (DTE) to identify the CUG to which the source and destination DTEs belong. The Closed User Group Selection Facility Suppress Option feature enables a user to configure an X.25 data communications equipment (DCE) interface or X.25 profile with a DCE station type to remove the CUG selection facility from incoming call packets destined for the preferential CUG only or for all CUGs. You can also remove the selection facility from a CUG with outgoing access (CUG/OA).
Frame Relay Switching Diagnostics and Troubleshooting
The Frame Relay Switching Diagnostics and Troubleshooting feature enhances Frame Relay switching functionality by providing tools to diagnose problems in switched Frame Relay networks. The show frame-relay pvc command has been enhanced to display detailed reasons why packets were dropped from switched PVCs. The command will also display the local status, the Network-to-Network (NNI) status, and the overall status of NNI PVCs. If a network problem is observed, the new debug frame-relay switching command can be used to display the status of packets on switched PVCs at regular intervals. This new debug command displays information such as the number of packets that were switched, why packets were dropped, and changes in status of physical links and PVCs.
Interworking Signaling Enhancements for H.323 and SIP VoIP
The Interworking Signaling Enhancements for H.323 and SIP VoIP feature enables VoIP networks to properly signal the setup and tear-down of calls when interworking with PSTN networks. These enhancements ensure that in-band tones and announcements are generated when needed so that the voice path is cut-through at the appropriate point of call setup and that early alerting (ringing) does not occur. In addition, support for network-side ISDN and the reducing of speech clipping is addressed.
NAT—Support for NetMeeting Directory (Internet Locator Service—ILS)
Microsoft NetMeeting is a Windows-based application that enables multi-user interaction and collaboration from a users PC over the Internet or an intranet. Support for the NetMeeting Directory (ILS) allows connections by name from the directory built into the NetMeeting application. Destination IP addresses do not need to be known in order for a connection to be made.
NTP MIB
The Network Time Protocol (NTP) is used to synchronize timekeeping among a set of distributed time servers and clients. The Cisco NTP MIB enables users to remotely monitor an NTP server using the Simple Network Management Protocol (SNMP), provided the MIB itself is implemented on that server. Use of the NTP MIB to monitor the NTP status of routing devices is accomplished using software on a Network Management System (NMS). There are no new or modified Cisco IOS software commands associated with this feature.
The Cisco implementation of the NTP MIB is based on NTP version 3 (RFC-1305). The MIB objects are all read-only. SNMP requests are processed by reading the corresponding variables from the NTP subsystem and returning them in the response. The NTP MIB defines a set of NTP server system objects, including an NTP server peers table and an NTP server filter register table. For complete details on the Cisco implementation of the NTP MIB, see the MIB file itself ("CISCO-NTP-MIB.my", available through Cisco Connection Online at http://www.cisco.com/public/mibs/v2/).
Parser Cache
The Parser Cache feature optimizes the parsing (translation) of Cisco IOS software configuration command lines by remembering how to parse recently encountered command lines. This feature was developed to improve the scalability of the Cisco IOS software command-line interface (CLI) parser when processing large configuration files. This improvement is especially useful for those cases in which thousands of virtual circuits must be configured for interfaces, or hundreds of access lists (ACLs) are required. The parser chain cache can rapidly recognize and translate configuration lines which differ slightly from previously used configuration lines (for example, pvc 0/100, pvc 0/101, and so on). Testing indicates an improvement to load time of between 30% and 36% for large configuration files when using the parser cache.
The parser cache is enabled by default on all platforms using Cisco IOS 12.1(5)T or later. A new command, [no] parser cache, allows the disabling or re enabling of this feature.
RSVP Support for Frame Relay
Queueing manages congestion on a router interface or a virtual circuit (VC). In a Frame Relay environment, the congestion point may not be the interface itself, but it may be the VC because of the committed information rate (CIR). For real-time traffic (voice flows) to be transmitted in a timely manner, the data rate must not exceed the CIR or packets might be dropped causing voice quality issues. Frame Relay traffic shaping (FRTS) is configured on the interfaces to control the outbound traffic rate by preventing the router from exceeding the CIR. This means that fancy queueing such as class-based weighted fair queueing (CBWFQ), low latency queueing (LLQ), and weighted fair queueing (WFQ), can run on the VC to provide the quality of service (QoS) guarantees for the traffic.
Previously, RSVP reservations were not constrained by the CIR of the flow's outbound VC. As a result, oversubscription could occur when the sum of the RSVP traffic and other traffic exceeded the CIR.
The RSVP support for Frame Relay feature allows RSVP to work with per VC (data link connection identifier (DLCI)) queueing for voice-like flows. Traffic shaping must be enabled in a Frame Relay environment for accurate admission control of resources (bandwidth and queues) at the congestion point; that is, the VC itself. Specifically, RSVP can work with VCs defined at the interface and subinterface levels. There is no limit to the number of VCs that can be configured per interface or subinterface.
SDLC SNRM Timer and Window Size Enhancements
The SDLC SNRM Timer and Window Size Enhancements feature introduces a new window size setting for SDLC configurations, and a new timeout setting for the SNRM frame. These enhancements change the operation of SDLC processing on a multidrop line.
Window Size Se1tting
Prior to this feature, all SDLC addresses on the multidrop had the same window count. Now the window count can be configured on a Physical Unit (PU) or SDLC address level. This enhancement gives a controller a different window size than other devices on the interface, and allows devices attached to the multidrop to be sized individually.
Timeout Setting for SNRM frame
Cisco IOS software SDLC implementation currently utilizes a common response timer (T1) for all outstanding commands. Calculating the maximum frame size and line speed produces a minimum time of 3.5 seconds for receiving acknowledgments; thus, polling stations used for link activation utilize this 3.5-second timer. This is a problem on a multidrop, because stations that do not respond to the SNRM will have 3.5 seconds of downtime-waiting before the next station that is active is polled. This enhancement reduces the time to stations that are waiting idle, as opposed to those that are active.
VIC-2BRI-NT/TE, MC3810-BVM4-NT/TE
The ISDN BRI NT/TE voice interface card (VIC-2BRI-NT/TE) for the Cisco 2600 and Cisco 3600 series and the ISDN BRI Voice Module (BVM4-NT/TE) for the Cisco MC3810 enable Cisco IOS software to replicate the public switched network interface to a PBX that is compatible with European Telecommunications Standards Institute (ETSI) NET3 and QSIG switch types.
Before this feature, customers with PBXs that implement only the BRI TE interface, have had to make substantial hardware and software changes on the PBX to implement the NT interface. The implementation of an NT interface on the router allows the customer to connect ISDN PBXs and Key Systems to a multiservice network with a minimum of configuration changes on the PBX.
VoIP Call Admission Control using RSVP
The VoIP Call Admission Control using RSVP feature synchronizes Resource Reservation Protocol (RSVP) procedures with H.323 Version 2 (Fast Connect) setup procedures to guarantee that the required Quality of Service (QoS) for VoIP calls is maintained across the IP network. Prior to Cisco IOS Release 12.1(3)XI, VoIP gateways used H.323 Version 1 (Slow Connect) procedures when initiating calls requiring bandwidth reservation. This feature, which is enabled by default, allows gateways to use H.323 Version 2 (Fast Connect) for all calls, including those requiring RSVP.
New Software Features in Release 12.1(3a)T1
The following new software features are supported by the Cisco MC3810 in Cisco IOS Release 12.1(3a)T1.
Caller ID
Caller ID (sometimes called CLID or ICLID for incoming call line identification) is an analog service offered by a Central Office (CO), which supplies calling party information to subscribers. Typically, the calling party number, and sometimes the name, appears on a station (also called extension) device such as a PC telephony software application screen or the display on a telephone. Type 1 Caller ID provides the calling party information while the call is ringing, and Type 2 Caller ID provides the additional convenience of calling number display while the recipient is on another call. In this release, Cisco provides only Type 1 Caller ID support.
Event MIB
The Event MIB is an asynchronous notification mechanism standardized for use by network management systems using Simple Network Management Protocol (SNMP). The Event MIB provides the ability to monitor Management Information Base (MIB) objects on a local or remote system using SNMP and initiate simple actions whenever a trigger condition is met (for example, an SNMP trap can be generated when an object is modified). By allowing notifications based on events, the Network Management System (NMS) does not need to constantly poll managed devices to find out if something has changed. When combined with the Expression MIB support introduced in Cisco IOS Release 12.0(5)T, Event MIB support in Cisco IOS software provides a flexible and efficient way to monitor complex conditions on network devices.
Trunk Conditioning for FRF.11 and Cisco Trunks
Trunk Conditioning for FRF.11 and Cisco Trunks is an enhancement that adds the following capabilities to the trunk conditioning feature on the Cisco 2600 and 3600 series routers and Cisco MC3810 series concentrators:
Busyout of ports interfacing with a local PBX if a network trunk is out of service (OOS)
Suppression of voice traffic when no calls are in progress or when the network trunk is OOS
This feature applies to analog telephony connections and digital T1/E1 using CAS/robbed-bit "ABCD" signaling. It does not apply to digital T1/E1 connections using CCS type signaling.
PSTN Fallback
PSTN Fallback provides a mechanism to monitor congestion in the IP network and either redirect calls to the PSTN or reject calls based on the network congestion. PSTN Fallback does not provide assurances that a call that proceeds over the IP network is protected from the effects of congestion. This is the function of the other QoS mechanisms such as IP RTP Priority or LLQ (low latency queueing).
PPP Over ATM SVC
PPP over ATM SVC implements standards-based PPP over ATM AAL5.
RSVP Support for LLQ
RSVP Support for LLQ (low latency queueing) is a network-control protocol that provides a means for reserving network resources—primarily bandwidth—to guarantee that applications transmitting end-to-end across networks achieve the desired quality of service (QoS).
RSVP enables real-time traffic (which includes voice flows) to reserve resources necessary for low latency and bandwidth guarantees. RSVP uses weighted fair queuing (WFQ) to provide fairness among flows and to assign a low weight to a packet to attain priority. However, the preferential treatment provided by RSVP is insufficient to minimize the jitter because of the nature of the queuing algorithm itself. As a result, the low latency and jitter requirements of voice flows might not be met in the prior implementation of RSVP and WFQ.
Consequently, a new queuing implementation, referred to as LLQ, was put in place. However, this new queuing implementation, by itself, is not sufficient to provide QoS for VoIP calls. Since the priority queue (PQ) in the queuing system does not distinguish between a VoIP packet of an existing call and a new call (as the queue does not keep the flow state), the queue may drop the packet of the existing call and service the packet of the new call due to strict policing. This means that RSVP is needed to perform admission control to avoid oversubscription of the priority queues.
HSRP Support for ICMP Redirect Messages (CSCdp37610)
The HSRP (Hot Standby Router Protocol) Support for ICMP Redirect Message feature enables ICMP redirects on interfaces configured with HSRP. This functionality works by filtering outgoing ICMP redirect messages through HSRP, where the next-hop IP address may be changed to an HSRP virtual IP address.
FXO Supervisory Disconnect Tone (CSCdr29301)
If the FXO Supervisory Disconnect Tone feature is configured and a detectable tone from the PSTN or PBX is detected by the digital signal processor (DSP), the analog FXO port goes on-hook. This feature prevents an analog FXO port from remaining in an off-hook state after an incoming call is ended. You can configure a voice port to detect either of the following tone types:
Disconnect tones from the PBX or PSTN—You can configure the FXO Supervisory Disconnect Tone feature to function in either of the following ways:
Continuously throughout the call duration
Before a call is answered
As part of the tone detection process by the DSP, a DSP event is reported to the host software.
Any tone received from the PBX or PSTN
Detection of any tone is effective only during call set-up (before a call is answered), and echo cancellation must be enabled to prevent disconnection due to detection of the router's own ringback tone.
New Software Features in Release 12.1(2)T
The following new software features are supported by the Cisco MC3810 in Cisco IOS Release 12.1(2)T.
AAA Server Group Deadtimer
The AAA Server Group Deadtimer feature allows each authentication, authorization, and accounting (AAA) server to be fully configured in the server group. Thus, it allows you to direct AAA traffic to separate groups of servers that have different operational characteristics.
With the introduction of this feature, deadtime has been added as a new attribute to the server group structure. In addition, a separate timer has been attached to each server host in every server group. Therefore, when a server is found to be unresponsive after numerous retransmissions and time-outs, the server is assumed to be dead. The timers attached to each server host in all server groups are triggered. In essence, the timers are checked and subsequent requests to a server (once it is assumed to be dead) are directed to alternate timers, if configured. When the network access server receives a reply from the server, it checks and stops all configured timers (if running) for that server in all server groups.
If the timer has expired, only the server to which the timer is attached is assumed to be alive. This becomes the only server that can be tried for later AAA requests using the server groups to which the timer belongs.
Dial Peer Enhancements
The dial peer configuration enhancements were previously implemented in 12.1(1)T for Voice over IP on several platforms. In the 12.1(2)T release, these same enhancements are now supported on additional platforms for Voice over Frame Relay and Voice over ATM. In addition, these enhancements are now supported on the Cisco MC3810 for Voice over IP.
The Ecosystem Gatekeeper Interoperability Enhancements, Phase 2 feature supplements the existing support for alternate gatekeepers and adds support for the alternate gatekeeper field (altGKInfo) to the admission rejection (ARJ). This allows a gateway to move between gatekeepers during the admission request (ARQ) phase.
QSIG Protocol Support
QSIG protocol support allows Cisco voice switching services to connect private branch exchanges (PBXs), key systems (KTs), and central office switches (COs) that communicate by using the QSIG protocol, which is becoming the standard for PBX interoperability in Europe and North America. QSIG is a variant of ISDN D-channel signaling. With QSIG, Cisco networks emulate the functionality of the Public-Switched Telephone Network (PSTN), and QSIG signaling messages allow the dynamic establishment of voice connections across a Cisco wide-area network (WAN) to a peer router, which can then transport the signaling and voice packets to a second Private Integrated Services Network Exchange (PINX). In addition, QSIG support can enable a toll-bypass application.
Simple Gateway Control Protocol Support on the Cisco MC3810 and Cisco 3600 Series Routers
Simple Gateway Control Protocol (SGCP) enables intelligent external call agents to control gateways in Voice over IP (VoIP) environments. Gateways include trunking and residential gateways. Call agents include Telecordia Technologies (formerly Bellcore) SM 1.5 and third-party products. This release supports SGCP Version 1.1+.
SGCP is intended for use in large IP networks typical of Competitive Local Exchange Carriers (CLECs) and Internet Exchange Carriers (IXCs).
Transparent CCS and Frame Forwarding Enhancements
The Transparent CCS (T-CCS) feature provides a way to interconnect private branch exchanges (PBXs), key systems (KTs), and central office switches (COs) when the Private Integrated Services Network Exchange (PINX) does not support QSIG, or when the PINX uses a proprietary solution. Transparent CCS allows the connection of two PBXs with PRI or BRI interfaces that use one CCS protocol without the need for interpretation of CCS signaling for call processing. A PBX PRI group is transported transparently through the data network and the feature preserves proprietary signaling. From the PBX standpoint, this is accomplished through a point-to-point connection. Calls from the PINXs are not routed, but follow a preconfigured route to the destination.
Trunk Conditioning Enhancements
Cisco MC3810 series concentrators support additional trunk-conditioning commands that specify various trunk-conditioning timing, signaling, and transmission options.
These additional commands provide enhanced control over rerouting of calls in cases of trunk failure, and increased bandwidth availability due to suppression of voice packets on out-of-service trunks
Voice Busyout Enhancements
The local voice busyout feature provides a way to busy out a voice port if a monitored network interface changes state. When a monitored interface changes to a specified state—to out-of-service or in-service—the voice port presents a seized/busyout condition to the attached PBX or other customer premises equipment (CPE). The PBX or other CPE can then attempt to select an alternate route.
Local voice busyout is supported on analog and digital voice ports using channel associated signaling (CAS).
This feature allows you to perform the following tasks:
Configure individual voice ports to enter the busyout state whenever specified network interfaces go out of service or come into service
Force individual voice ports into the busyout state
Define the voice-port actions for the busyout state
Force one or more DS0 timeslots on a controller into the busyout state
Voice Port Enhancements
The Cisco 2600 series and 3600 series routers and Cisco MC3810 series multiservice access concentrators support data, voice, and video transport to varying degrees. Numerous voice port commands and features that were previously limited to one or two of these product series have been extended to additional product series, and differences in configuration commands have been reduced or eliminated.
Increase the voice capabilities of the product series gaining new features
Increase the level of interoperability between the product series
Simplify the configuration procedures
Voice Port Testing Enhancements
Voice port testing enhancements expand the capabilities to analyze and troubleshoot voice ports on the Cisco 2600 and 3600 series routers and MC3810 series concentrators.
Voice over ATM with AAL2 Trunking
Voice over ATM with AAL2 trunking enables the Cisco MC3810 series concentrators to carry voice traffic (for example, telephone calls and faxes) over ATM networks using AAL2.
This feature provides the following improvements to the Cisco MC3810 capabilities:
Increased quality of service (QoS) capabilities
Standards-based transport of voice over ATM
Bandwidth-efficiency
Robust architecture
Voice over Frame Relay Using FRF.11 and FRF.12 Configuration Updates
Voice over Frame Relay functionality has been updated in this release, so that configuration on all supported platforms is nearly identical. In Cisco IOS Release 12.0(4)T, when support for Voice over Frame Relay Using FRF.11 and FRF.12 was introduced, configuration procedures were different depending on the router platform used.
Some commands introduced in earlier Cisco IOS releases have been removed or modified. In addition, this release provides support for digital voice calls for Voice over Frame Relay on the Cisco 2600 and 3600 series routers. In previous releases, the Cisco 2600 and 3600 series only supported analog voice calls for Voice over Frame Relay.
Voice over IP
Voice over IP (VoIP) enables a Cisco MC3810 concentrator to carry voice traffic (for example, telephone calls and faxes) over an IP network. Voice over IP is primarily a software feature; however, to support this feature, a Cisco MC3810 must be equipped with a digital voice module (DVM) or an analog voice module (AVM). The Cisco MC3810's LAN/WAN multiservice routing capabilities provide analog and digital (T1/E1) VoIP gateway capabilities for packetized voice traffic.
In Voice over IP, the DSP segments the voice signal into frames, which are then coupled in groups of two and stored in voice packets. These voice packets are transported using IP in compliance with ITU-T specification H.323. Because it is a delay-sensitive application, you need to have a well-engineered network end-to-end to successfully use Voice over IP. Fine-tuning your network to adequately support Voice over IP involves a series of protocols and features geared toward quality of service (QoS). Traffic shaping considerations must be taken into account to ensure the reliability of the voice connection.
Software Features No Longer Supported in Release 12.1(2)T
Beginning in Cisco IOS Release 12.1(2)T, the following features previously released for the Cisco MC3810 are no longer supported:
Voice over HDLC
Cisco MC3810-IGX 8400 Interworking
New Hardware Features in Release 12.1(1)T
There are no new hardware features supported by the Cisco MC3810 in Cisco IOS Release 12.1(1)T.
New Software Features in Release 12.1(1)T
The following new software feature is supported by the Cisco MC3810 in Cisco IOS Release 12.1(1)T.
H.323 Version 2 Phase 2 Enhancements
Cisco H.323 Version 2 Phase 2 upgrades Cisco IOS software by adding several optional features of the H.323 Version 2 specification and facilitates customized extensions to the Cisco Gatekeeper.
H.323v2 Fast Connect
The Fast Connect feature allows endpoints to establish media channels without waiting for a separate H.245 connection to be opened. This streamlines the number of messages that are exchanged and the amount of processing that must be done before endpoint connections can be established.
H.245 Tunneling
Through H.245 tunneling, H.245 messages are encapsulated within Q.931 messages without using a separate H.245 TCP connection. When tunneling is enabled, one or more H.245 messages can be encapsulated in any Q.931 message. H.245 tunneling is not supported as a standalone feature; initiation of H.245 tunneling procedures can be initiated only by using the dtmf-relay command, and only from an active Fast Connect call. Furthermore, if dtmf-relay is configured on a Version 2 VoIP dial peer and the active call has been established by using Fast Connect, tunneling procedures initiated by the opposite endpoint are accepted and supported.
H.245 tunneling is backward compatible with H.323 Version 1 configurations.
H.450.2 Call Transfer
Call Transfer allows an H.323 endpoint to redirect an answered call to another H.323 endpoint. Cisco gateways support H.450.2 Call Transfer as the transferred and transferred-to party. The transferring endpoint must be an H.450-capable terminal; the Cisco gateway cannot act as the transferring endpoint. Gatekeeper-controlled or Gatekeeper-initiated Call Transfer is not supported.
Note Certain devices are limited in their support of H.450. The Cisco 1700 and ubr920
platforms do not support Interactive Voice Response (IVR). Therefore, these platforms are
not able to act as H.450 Transferring endpoints.
H.450.3 Call Deflection
Call Deflection is a feature under H.450.3 Call Diversion (Call Forwarding) that allows a called H.323 endpoint to redirect the unanswered call to another H.323 endpoint. Cisco gateways support H.450.3 Call Deflection as the originating, deflecting, and deflected-to gateway. The Cisco gateway as the deflecting gateway will support invocation of Call Deflection only by using an incoming PRI QSIG message (a Call Deflection cannot be invoked by using any other trunk type).
Important Notes
This section contains important information about the use of your Cisco IOS Release 12.1(3a)T1 and Cisco IOS Release 12.1(5)Tsoftware.
CSCdr91706 and Cisco IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the Cisco IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected Cisco IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at
Last Maintenance Release of Cisco IOS Release 12.1T
The last maintenance release of the 12.1T release train is 12.1(5)T. The migration path for customers who need bug fixes for the 12.1T features is the 12.2 mainline release. The 12.2 mainline release has the complete feature content of 12.1T and will eventually reach general deployment (GD).
The last maintenance release was renamed from 12.1(4)T to 12.1(5)T to synchronize with its parent software base, the 12.1(5) mainline release, and to reflect that 12.1(5)T has all the bug fixes of the 12.1(5) mainline release. The 12.1T release train is a superset of the 12.1 mainline release; hence any defect fixed in the 12.1 mainline is also fixed in 12.1T. The set of features for 12.1(4)T is the same as that for 12.1(5)T. There was no change in the feature content of the release. The release was renamed so that the releases would be consistent with the Cisco release process.
Cisco IOS Release 12.1(3)T and 12.1(3a)T1 Voice Issues
Because of a number of issues with H.323 and SIP voice support on the Cisco AS5300, Cisco AS5800, Cisco 2600 series, Cisco 3600 series, and Cisco MC3810 which arose in Cisco IOS Release 12.1T, use of 12.1(3)T and 12.1(3a)T1 is strongly discouraged.
Cisco IOS Release 12.1(3)T and 12.1(3a)T1 is being made available for dial applications only. The problems with voice in this release are being tracked in the following DDTS reports:
CSCdr78203 PC-to-phone one way audio problem
CSCdr79120 Some information elements not passed between ISDN and H.323
CSCdr78 A simple call via a SW (T1pri) cannot connect
CSCdr75660 Like CSCdr64591. Alerting but no ringback in ISDN
CSCdr90963 Inband tones/announcements do not propagate for most ISDN switches
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently being migrated into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 8.

Using the Cisco MC3810 with QSIG or BRI
Serial port 1 is restricted to DCE operation when the following occurs:
QSIG is enabled.
BRI voice module (BVM) is installed and BRI is enabled.
BRI S/T backup port is installed and enabled on the MFT.
Using the Cisco MC3810 with the PSTN
This section includes important notes regarding use of the Cisco MC3810 with the Public Switched Telephone Network (PSTN).
Connections to the PSTN
Exercise care when connecting switched voice ports on the Cisco MC3810 directly to the PSTN because improper configurations can expose a corporate network to telephone fraud.
Switched Access from the PSTN
The Cisco MC3810 can connect a user from the PSTN directly to the corporate wide-area telephone network. You can configure the Cisco MC3810 as a phone switch that can switch a user to any location in that network, even to remote locations that are connected again to another PSTN. However, the Cisco MC3810 does not provide any mechanism to restrict users from calling after they are connected. Without proper network design, this condition could result in the unauthorized use of the corporate network for making calls at the corporation's expense. To prevent this from occurring, Cisco does not recommend connecting a switched voice interface on the Cisco MC3810 directly to the PSTN. Instead, it should be connected to a PBX that implements a security scheme that prevents unauthorized use.
Nonswitched Calls
The same opportunity for illicit use does not exist for nonswitched call types such as pass-through connections, although the possibility for fraud does exist at the direct contact point. Pass-through calls create a path to only a single location specified by the network administrator. For example, a pass-through connection might be used to pass a trunk from a PBX to the PSTN. In this case, the trunk on the PBX always passes straight through the Cisco MC3810 to the PSTN. As a result, the necessary security is provided by the PBX.
Caveats
Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
For information about caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats, and select severity 3 caveats, and is located on CCO and the Documentation CD-ROM.
All caveats in Release 12.1 are also in Release 12.1(5)T.
For information on caveats in Cisco IOS Release 12.1(5)T, see Caveats for Cisco IOS Release 12.1 T , which lists severity 1 and 2 caveats and is located on CCO and the documentation CD-ROM.
Open Caveats—Cisco IOS Release 12.1(3a)T1
The caveats listed in this section are open in Release 12.1(3a)T1.
CSCdr62168
Upon system initialization, ATM permanent virtual circuits (PVCs) are left in the inactive state and do not change to the active state unless the user issues a shutdown/no shutdown of the associated ATM interface in configuration mode.
Workaround: Reinitialize the interfaces manually.
CSCdr87083
After a user runs Simple Gateway Control Protocol (SGCP) calls for several minutes, a Cisco router experiences 100 percent CPU usage and cannot process any calls. The router will not reload automatically. The CPU high utilization is at VOIP_RTCP process. There is no workaround.
