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 8 MB, and a 16-MB upgrade option 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:
•
Cisco CLI
•
•
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.

4 Applicable to data-only interfaces.
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(5)XK1.
New Features in Release 12.0(5)XK1
The following hardware and software enhancements are available for the Cisco MC3810 in Cisco IOS Release 12.0(5)XK1.
Video over ATM SVCs and PVCs
Video over ATM switched virtual circuits (SVCs) expands the capabilities of the Cisco MC3810 multiservice access concentrator to provide cost-effective, dynamic, and flexible video conferencing system support. By using a plug-in video dialing module (VDM) to provide an RS-366 dialing interface to an H.320 video codec, the Cisco MC3810 automatically accepts dial-out requests from the video system. The codec connects to either of the Cisco MC3810 serial ports and also to the Cisco MC3810 RS-366 dial-up port.
The current feature also improves permanent virtual circuit (PVC) support by permitting PVC connections with automatic connection through a serial port. Each codec must place a call to the other video conferencing system before the expiration of the video codec time-out period (set on the codec, usually one minute). By using a video dial map, each system reconciles the dialed number with a PVC that has already been configured, allowing fast connectivity.
FRF.5 Enhancement for the Cisco MC3810
The Frame Relay-ATM Network Interworking (FRF.5) feature that was first introduced in 11.3(1)MA has been enhanced to allow setting the mode of the Discard Eligibility and Cell Loss Priority fields as defined in the FRF.5 implementation agreement.
Network Interworking (FRF.5) allows the transparent tunneling of Frame Relay user traffic and PVCs over ATM. This function is often used to link Frame Relay networks over an ATM backbone. The most distant nodes must be configured to interoperate with one another—in contrast to Service Interworking—because intact Frame Relay frames are sent over the ATM network. The ATM backbone is used as an alternative to a leased line and provides cost savings over leased lines. There can be a one-to-one relationship between Frame Relay and ATM PVCs, or multiple Frame Relay PVCs can be multiplexed into a single ATM PVC.
FRF.8 for the Cisco MC3810
FRF.8 Frame Relay to Asynchronous Transfer Mode (ATM) Service Interworking allows connection of Frame Relay traffic across high-speed ATM trunks using ATM standard Network and Service Interworking. Cisco IOS Release 12.0(5)XK introduces Frame Relay-to-ATM Service Interworking for data transfer, outlined in Frame Relay Forum implementation agreement FRF.8 and designed for the Cisco MC3810 multiservice access concentrator.
Service Interworking connects a Frame Relay network to an ATM network while the networks function independently, allows bidirectional PVC protocol conversion functions, and provides a standards-based solution for service providers, enterprises, and end users.
This feature supports two modes of operation of the interworking function (IWF) for upper-layer user protocol encapsulation—transparent mode and translation mode:
•
•
Multimedia Conference Manager (MCM H323)
Use the Multimedia Conference Manager to enable your current internetwork to route bit-intensive data, such as audio telephony, video and audio telephony, and data conferencing by using existing telephone and ISDN links—without degrading the network's current level of service. The Multimedia Conference Manager feature provides H.323 application options previously unavailable. By using Multimedia Conference Manager, you can implement H.323-compliant applications on existing networks in an incremental fashion without upgrades. This feature also provides a rich list of networking capability, including:
•
•
The Multimedia Conference Manager feature provides network administration mechanisms to support H.323 applications without impacting the mission critical applications running on today's networks. Multimedia Conference Manager is implemented on Cisco IOS software. Multimedia Conference Manager provides the network administrator with these abilities:
•
•
•
•
•
Multimedia Conference Manager has two principal functions: gatekeeper and proxy. These functions are unique to Multimedia Conference Manager. Similar robust features are currently not available in other vendor solutions.
Gatekeeper subsystems provide:
•
•
•
•
•
Starting with Cisco IOS Releases 11.3(6)Q and 11.3(7)NA and later releases, you can configure Cisco gatekeepers to use the Cisco Hot Standby Routing Protocol (HSRP), so that when one gatekeeper fails, the standby gatekeeper assumes its role.
Proxy subsystems provide:
•
•
•
•
Voice and Data over ATM Switched Virtual Circuits
VoATM SVCs allow the Cisco MC3810 to transfer voice and data dynamically and as needed—without tying up the resources required for static, manually provisioned permanent virtual circuits (PVCs). An SVC connection is initiated for each call, and each request includes bandwidth and quality-of-service (QoS) information required for the connection. SVCs are ideal for networks that are highly interconnected, where scalability is essential, and in situations where traffic is sporadic. In addition, service providers often proffer more advantageous, use-based pricing options for SVCs.
VoATM (voice over ATM) using SVCs on the Cisco MC3810 includes all of the voice features that the Cisco MC3810 supports for PVCs and for Frame Relay transport. Like other Cisco voice implementations, VoATM is based on dial peers and uses ATM Adaptation Layer 5 (AAL5). ATM SVC service operates much like X.25 SVC service, although ATM allows much higher throughput. It requires a signaling protocol between a router or multiservice access concentrator and ATM switch. The ATM signaling software provides a method of dynamically establishing, maintaining, and clearing ATM connections at the User-Network Interface (UNI). In UNI, the router serves as the user and the ATM switch is considered the network. The router does not perform call-level routing. Instead, the ATM switch does the ATM call routing, and the router directs packets through the resulting circuit.
Important Notes
This section contains important information about the use of your Cisco IOS Release 12.0(5)XK1 software.
Cisco IOS release 12.0(5)XK1 is supported on all Cisco 2600, 3600, and MC3810 platforms and incorporates a number of bug fixes and enhancements. These include improvements to the echo canceller located within the DSP firmware. These improvements result in better performance during off-net calls and within noisy environments.
Refer to the Caveats section for details on individual bug fixes found within this release.

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 because 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(5)XK1.
For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0 that describes caveats affecting all maintenance releases.
For information on other caveats that also apply to this release, see Caveats for Cisco IOS Release 12.0 T which lists severity 1 and 2 caveats, and is located on CCO and the Documentation CD-ROM

Basic System Services
•
Brings IOS up to RFC 2217 spec. Adds in extra flow control for faxing through IOS. Corrects [now ignores] software flow control issue.
•
Error messages are generated by RSP routers with VIP cards in some cases. The error messages are generally benign, indicating temporarily out of memory situations, which are then recovered from.
•
SegV Exception in peer_list_sum, NTP related
When utilizing ntp private mode and control type messages for remote query, it is possible to see a router crash or traceback messages.
•
If sh run or wr t are issued at exactly the same time from two different VTY, one session may finish before the other and trash a variable that still need to be used by the 1st session which causes a router crash.
Workaround: Don't do sh run at the same time from 2 VTY's.
•
If you have a Vip2-50 with a ESA module for hardware encryption, you might be seeing this problem. Execute show version and look for 12.0.5, if rsp-dsv56i-mz.120-5 show interface stat and look for...

The use of the command backup interface bri 0 breaks the tdm-group command under the T1/E1 controllers in Cisco IOS 12.0(5)XK. Removing the command, saving the config to nvram, and reloading doesn't resolve the problem. The user must either:
write erase and reload
-or-
boot the router ignoring vnram
Reconfigure the router without the faulty command. The work-around is to disable ISDN backup.
IBM Connectivity
•
A Cisco router using Advanced Peer-to-Peer Networking (APPN) may consume excessive CPU while issuing messages during a Locate storm. In particular, message: XXXTPD02_LOGMSG_01 can be issued repetitively.
•
APPN Network Node router fails to allocate the conwinner session of its dual CP-CP session with an adjacent End Node. The conloser session will be setup correctly, but the conwinner sessions fails with sense 80140003 as indicated in the debug appn ss. The problem results after changing an adjacent Network Node to an End Node. The workaround is to cycle the link for this End Node.
•
Router may crash when creating a circuit history for a DLSw lite circuit.
Workaround is to disable circuit history logging by configuring no dlsw history-log.
Interfaces and Bridging
•
If an interface on a HSSI 1 port (PA-H or H1T+) card goes down/down and you see the following error message, you may be experiencing this problem:
%MUSELIX-1-STOPFAIL: XXXX: Stop Failed at disable port (XXXX = the interface affected) %MUSELIX-1-STARTFAIL: XXXX: Start Failed at enable port MUESLIX-1-FAILURE_CAUSE: SerialX/X:This problem is caused by several factors.
Once it falls into this state, execute the following (undocumented) test commands -- (<CR> is a carriage return):
term len 0<CR> sh cont h 1/0<CR> test tpu b<CR> 1/0<CR> g<CR> x<CR> y<CR> r<CR> s<CR> 3<CR> q<CR> test tpu b<CR> 1/1<CR> g<CR> x<CR> y<CR> r<CR> s<CR> 3<CR> q<CR> test len 24<CR>
An example of this process can be obtained by using Bug Navigator II.
Note
Resolved Caveats for Release12.0(5)XK1
All caveats listed in this section are resolved in Release 12.0(5)XK1. This section only describes severity 1 and severity 2 caveats.
•
Crashed happened on routing_svc, switching_svc, and bridging_svc HAWK testing after the configuration is done. It is in version 12.0(5.1)PI6.
The same problem is also seen on 12.0(19990715:065145) [BLD-v120_5_xk_throttle.990714 109] where is stack trace is the same.
•
Regression of BVM (qsig) failed to pass the SETUP to the PBX (i.e., making an outgoing call). Apparently, some code changes for other boxes introduced the problem. A new field called bchan_reassigned is added to the isdn_bri structure. This structure is used to make calls to routines such as process_bri_call. For the MC3810, we have an api (ccsapi.c) to translate ccs api messages to isdn host messages, the person(s) who add this field forgot to initialize the field for this api, and thus contains garbage.
This is causing the "UKNOWN BCHANNEL" problem shown by the regression.
•
Clocking configuration information may be over written if the hw work-around software is running while a clocking config change is made.
•
Cannot configure more than one channel-group on E1.
•
In FRF8, the IWF is setting the DE bit of the FR frame only if the last cell of a AAL5 pack has the CLP bit set. According to the FRF.8 spec, the DE bit should be set if any of the cells of a fragmented AAL5 packet has the CLP bit set.
•
FRF.8 ATM PVCs cannot be removed if the corresponding FR VCs are not configured on the IWF.
