Release Notes for the Cisco MC3810 for Cisco IOS Release 12.0(3)XG

Release Notes for the Cisco MC3810 for Cisco IOS Release 12.0(3)XG

March 29, 1999

These release notes describe new features and significant software components that support Cisco IOS Release 12.0(3)XG for the Cisco MC3810 multiservice access concentrator. Cisco IOS Release 12.0(3)XG is based on Cisco IOS Release 12.0(3)T.

Use these release notes with the cross-platform Release Notes for Cisco IOS Release  12.0 located on Cisco Connection Online (CCO) and the Documentation CD-ROM. 

For a list of software caveats that apply to Release 12.0(3)XG, refer to the "Caveats" section.

Contents

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:

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(3)XG.

New Features in Release 12.0(3)XG

The following hardware and software enhancements are available for the Cisco MC3810 in Cisco IOS Release 12.0(3)XG.

ISDN BRI Voice on the Cisco MC3810

With the optional BRI voice module (BVM) installed, the Cisco MC3810 multiservice access concentrator provides four ISDN Basic Rate Interface (BRI) ports for connection to ISDN PBXs (PINXs). The BVM has four ISDN BRI ports for voice traffic. Each BRI port supports two voice channels (ISDN B channels) and one signaling channel (ISDN D channel). The BRI voice ports have the following features:

Voice over Frame Relay Using FRF.11 and FRF.12

The Voice over Frame Relay (VoFR) capabilities that were introduced on the Cisco MC3810 multiservice access concentrator beginning with IOS Release 11.3 are now extended to the Cisco 2600, 3600, and 7200 series router platforms.

The following additional functionality is supported in Release 12.0(3)XG:

When VoFR is implemented on a Cisco router, the router is able to carry voice traffic, such as telephone calls and faxes over a Frame Relay network.

This feature also adds support for full FRF.11 and FRF.12 compliance to the Cisco MC3810 and is backward-compatible with earlier versions of the Cisco MC3810, which used a fragmentation format based on an early draft version of FRF.12.

Important Notes

This section contains important information about the use of your Cisco IOS Release 12.0(3)XG software.

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

This section contains open caveats for the current Cisco IOS maintenance release only. Caveats describe unexpected behavior or defects in Cisco IOS software releases. The caveats listed below are severity 3, moderately serious, with the exception of CSCdk74350, as noted in the description.

For information on caveats in Cisco IOS Release 12.0, refer to the document Caveats for Cisco IOS Release 12.0  that describes caveats affecting all maintenance releases. Because Release 12.0(3)XG is based on Release 12.0, all caveats in Release 12.0 are also in Release 12.0(3)XG.

Cisco IOS Release 12.0(3)XG is also based on Cisco IOS Release 12.0(3)T. For information on other caveats that also apply to this release, refer to the Caveats for Cisco IOS Release 12.0 T document. This caveats document lists severity 1 and 2 caveats for Release 12.0 T. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. From CCO, log in and click on this path: Service & Support: Online Technical Support: Software Bug Toolkit. You can also find Bug Navigator II at http://www.cisco.com/support/bugtools.
This is a severity 2 caveat. On permanent calls (cisco-trunk or frf11-trunk) between two Cisco MC3810 units, the Calling and Called fields within the Call Detail Record (CDR) are empty.
When making a fax call through a permanent connection using either a frf11-trunk or cisco-trunk, some brands of fax machine may report an error at the end of the fax call, even though the fax was transmitted correctly.
The problem is caused by a slightly premature on-hook signal going to the fax machine at the end of the call. This causes the final fax T.30 DCN (disconnect message) to the receiving fax machine to be chopped off.
At this point the transmission of the fax image is complete, but some fax machines may report an error as a result of the missing DCN message. The fax machine continues to operate correctly after this and can receive and send additional fax messages.
The router may crash unexpectedly if the voice mode for a frame-relay permanent virtual circuit (PVC) is changed too quickly while voice connections are active on the PVC.
Workarounds: Shut down the voice connections using the PVC (for example, by executing no connection trunk on the voice port) before attempting to change the PVC voice mode from vofr to vofr cisco. The router does generate a warning message, informing the user that connections are active, when the command no vofr is entered.
Alternatively, simply wait for about 30 seconds after issuing the no vofr command and before entering the command vofr cisco, giving the voice connections time to be torn down completely and avoid this problem.
The DTMF detector used for DTMF digit relay is designed to meet the requirements of EIA-464, which are: "The receiver should register DTMF signals having a power per frequency of -25 to 0 dBm."
With this range, one would expect the DTMF digit-relay feature to correctly handle digits generated by a PBX or CO for call routing on trunks or tie lines. However, this range may not be sufficient to handle DTMF digits sent after call setup over long distance---for example, when accessing a voice mail system---where the total call path has a significant amount of attenuation.
