Introduction
As part of an enterprise backbone or as customer premises equipment (CPE) to service provider-managed network services, the Cisco MC3810 multiservice access concentrator reduces operating costs and complexity, and increases network throughput and performance. Cisco IOS software fully supports the Cisco MC3810 for multiprotocol routing, bridging, and Systems Network Architecture (SNA).
To make file management easier, the Cisco MC3810 provides a complete file system for software images, message files, and reports. The standard Flash memory size is either 8 MB or 16 MB, with 16-MB or 32-MB upgrade options that can simultaneously hold two code images for fail-safe upgrades.
You can manage the Cisco MC3810 by using 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:
•
•
•
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, such as HP OpenView.

Cisco IOS File System
To make file management easy, 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 can simultaneously hold two code images for fail-safe upgrades.
New and Changed Information
The following sections list new information about the Cisco MC3810 in Cisco IOS Release 12.0(7)XK3.
New Features in Cisco IOS Release 12.0(7)XK3

New Features in Release 12.0(7)XK
The following hardware and software enhancements are available for the Cisco MC3810 in Cisco IOS Release 12.0(7)XK.
Transparent CCS and Frame Forwarding Enhancements on the Cisco MC3810
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 pre-configured route to the destination. Transparent CCS is implemented in two ways:
•
•
Note
The Transparent CCS feature only affects the functionality related to the D channel signaling interface (serial 1:23 for T1 and serial 1:15 for E1). This feature does not change the bearer channel (B channel) functionality for Frame Relay that was implemented in earlier Cisco IOS releases.
For details, see the online feature module.
QSIG Protocol Support on Cisco MC3810, 7200, 2600, and 3600 Series Routers
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 inter-operability 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).
The Cisco voice packet network appears to the traditional QSIG PBXs as a distributed transit PBX that can establish calls to any PBX, non-QSIG PBX, or other telephony endpoint served by a Cisco gateway, including non-QSIG endpoints. When originating and terminating on QSIG endpoints, the QSIG messages are passed transparently across the network; the PBXs are responsible for processing and provisioning the supplementary services. When linking QSIG and non-QSIG endpoints served by a Cisco packet voice gateway, only basic calls are supported. In addition, all switched voice connections must be established and torn down in response to QSIG control messages.
QSIG support includes the following capabilities:
•

For details, see the online feature module.
Voice over Frame Relay Using FRF.11 and FRF.12
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 differed depending on the router platform used.
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.
In Cisco IOS releases prior to release 12.0(5)XE, the Cisco 7200 could only act as a tandem router in Voice over Frame Relay topologies, and could not terminate VoFR calls. Beginning in Cisco IOS Release 12.0(5)XE and 12.1(1)T, the Cisco 7200 can terminate VoFR calls.
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), as well as a Multiflex Trunk Module (MFT). 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.
VoIP is supported by the following images only:
•
•
•
•
Voice Port Enhancements
The Cisco 2600, 3600, and MC3810 series routers and concentrators all 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 platforms have been extended to additional platforms, and differences in configuration commands have been reduced or eliminated.
•
This feature allows the user to configure a voice-port connection mode and destination telephone number for permanent connections. This feature was unified across the Cisco MC3810, 2600, and 3600 platforms in IOS Release 12.0(7)XK3.
•
This feature enables the user to specify on and off times for ringing pulses on an FXS voice port The ability to specify ring cadence is a new feature on the Cisco 2600 and 3600 platforms, and the syntax for configuring the ring cadence is new in IOS Release 12.0(7)XK3.
•
This feature makes it possible to disable or enable the auto-cut-through feature on E&M voice ports. When enabled, this feature makes call completion possible when a PBX does not provide an M-lead response. This feature is enabled by default on E&M voice ports. This is a new feature on the Cisco 2600 and 3600 platforms in IOS Release 12.0(7)XK3.
•
This feature allows the user to modify the functioning of transmit and receive signaling bits for E&M and E&M MELCAS voice signaling.These are new features on the Cisco 2600 and 3600 platforms in IOS Release 12.0(7)XK3.
•
This feature provides the ability to force individual transmit and receive signaling bit states on any voice port type. This is a new feature on the Cisco 2600 and 3600 platforms in IOS Release 12.0(7)XK3.
•
This feature supports configuring an FXS or FXS Melcas voice port to return an acknowledgment upon receipt of a disconnect signal. This is a new feature on the Cisco 2600 and 3600 platforms in IOS Release 12.0(7)XK3.
•
This feature enables the tuning of the playout buffer to accommodate packet jitter caused by switches in the WAN. This is a new feature on the Cisco 2600 and 3600 platforms in IOS Release 12.0(7)XK3.
•
This feature allows the user to change various timing characteristics on voice ports, including:

Important Notes
This section contains important information about the use of your Cisco IOS Release 12.0(7)XK3 software. Cisco IOS Release 12.0(7)XK3 is supported on all Cisco 2600, 3600, and MC3810 platforms and incorporates a number of bug fixes and enhancements. Refer to the Caveats section for details on individual caveats closed within this release.
Caveat 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 http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
Using IGX Interworking
With Cisco IOS Release 12.0(7)T and later releases, the IGX Interworking feature is no longer supported by the Cisco MC3810. The following commands used to configure this feature are no longer supported beginning in this release:
•
•
•
•
•
•
•
Using Voice Over HDLC
With Cisco IOS Release 12.0(7)T and later releases, the Voice over HDLC feature is no longer supported by the Cisco MC3810.
Using the Cisco MC3810 with QSIG or BRI
Serial port 1 is restricted to DCE operation when the following occurs:

Using the Cisco MC3810 with the PSTN
This section describes important notes regarding use of the Cisco MC3810 with the Public Switched Telephone Network (PSTN).
Connections to a PSTN
Be careful when connecting switched voice ports on the Cisco MC3810 directly to the PSTN. Improper configurations can expose the corporate network to telephone fraud.
Switched Access from the PSTN
The Cisco MC3810 has the capability to connect a user from the PSTN directly to the corporate wide-area telephone network. Using the Cisco MC3810 as a phone switch, you can configure the access concentrator to switch the 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, you should not connect a switched voice interface on the Cisco MC3810 directly to the PSTN. Instead, connect the interface to a PBX that implements a security scheme that prevents unauthorized use.
Non-Switched Calls
The same opportunity for illicit use does not exist for non-switched 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 a single location specified by the network administrator. For example, you might use a pass-through connection 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 are less serious. This section only contains open and resolved caveats for the current Cisco IOS maintenance release. All caveats in Release 12.0 and Release 12.0 T are also in Release 12.0(7)XK3.

These alignment error messages do not affect connectivity or cause packet loss. There is no workaround.
IP Routing Protocols
•
A Cisco router that has tag switching enabled and is running Cisco IOS Release 12.0(5)T might reload if a tag advertisement appears in a certain time window when a related routing update takes place. An ATM interface transition might cause this condition. There is no workaround.
Miscellaneous
•
When tunneling IPX over an IP tunnel, and when using an extended inbound access list for IP on the tunnel interface, the IPX traffic gets blocked by the access list. As a workaround a "permit gre" statement could be added in the extended access list.
•
When changing the traffic shaping parameter while traffic is going through, NRP might have a software crash. There is already a fix, but not in 11.3(9)DB2. One possible workaround is to shutdown the interface during configuration update.
•
In Cisco IOS Release 12.0 T, Cisco express forwarding (CEF) will not work with bundle virtual circuits (VC)s if you use subinterfaces that are part of the same physical interface. There is no workaround.
Wide-Area Networking
•
If there are calls that are up, and the signaling controller (SC) does a switchover, some existing active calls are dropped on the network access server. The workaround is to upgrade to Cisco IOS Release 12.0(7)T or higher.
Basic System Services
•
There is an issue with mode CAS that will result in some line code violations be detected on the show controller. These errors only appear when the router or the PBX is signaling for a time slot via frames 6 and 18. Because these errors only get clocked during signaling, it does not appear to affect voice quality.
•
On the Cisco MC3810, comfort-noise generation cannot be disabled. A workaround is to disable VAD because comfort-noise is only applicable when VAD is engaged.
•
The command-line interface (CLI) voice class permanent command has been restored. However, the CLI voice class codec command is still not working. There is no workaround.
•
The fax-rate disable command in the dial-peer configuration does not work. Fax-relay is used to carry faxes instead of simple pass-through in the case of G.711 or G.726 adaptive differential pulse code modulation (ADPCM). Use of fax-relay restricts a Cisco MC3810 router to a maximum of 12 calls instead of 24 calls when using G.726. There is no workaround.
•
Voice-drop outs and dialed digit drops can occur in MC3810 systems configured with a large number of dial-peers in which the first one or two digits of the destination-pattern are the same. There is no workaround except to attempt to reduce the number of dial-peers used.
Miscellaneous
•
If voice activity detection (VAD) is enabled on Voice over Frame Relay (VoFR) or Voice over ATM (VoATM) calls on a Cisco 3810 router, significant voice quality degradation might occur.
The workaround is to disable VAD by entering the no vad command in all VoFR or VoATM dial peers.
•
This breaks L2F+MLP under VPDN and Multi-Chassis in 12.0(05.00.02)T01 if it is process switching. The workaround is to make sure it is fast switching out of the tunnel. By setting pak->netowrk_start to the same place pointed to by pak->datagramstart in l2f_coalesce_and_process_pak() will solve this bug.
