Release Notes for Cisco MC3810 for Cisco IOS Release 12.1

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 support Cisco IOS Release 12.1, up to and including Release 12.1(4). These release notes are updated as needed to describe new features, memory recommendations, hardware support, software platform deferrals, and changes to related documents.

For a list of software caveats that apply to Cisco IOS Release 12.1(4), refer to the document Caveats for Cisco IOS Release 12.1 that accompanies these release notes. The caveats document is updated for every maintenance release and is located on Cisco Connection Online (CCO) and the Documentation CD-ROM.

Use these release notes with the cross-platform Release Notes for Cisco IOS Release 12.1 located on Cisco Connection Online (CCO) and the Documentation CD-ROM.

These release notes describe the following topics:

Introduction

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).

System Requirements

This section describes the system requirements for Cisco IOS Release12.1(4):

Hardware Supported

Cisco IOS Release12.1(4) supports the Cisco MC3810 multiservice access concentrator. The Cisco MC3810 base chassis is a semi-fixed configuration router that can be customized for a specific application at the factory or in the field by a qualified technician. The base chassis includes the following components:

One fixed Ethernet LAN port
A console port and an auxiliary port
Two synchronous serial ports
Five mounting areas for functional modules that support additional capabilities
AC, DC, or redundant power supply option

Cisco MC3810 series concentrators are supplied in various standard hardware configurations. These are equipped with different sets of functional modules to provide specific functional capability. Many configurations are possible, but they are all variations of the basic categories described in Table 2. Supported hardware is shown in Table 3. The chassis opening for any mounting area not equipped with a functional module is closed off with a removable cover plate.

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.

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 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.

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 is located on CCO and the Documentation CD-ROM.

Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. From the CCO home page, log in and click on this path: Software Center: Cisco IOS Software: Cisco IOS Bug Toolkit: Cisco Bug Navigator II. You can also find Bug Navigator II at
http://www.cisco.com/support/bugtools

The following sections describe the documentation available for the Cisco MC3810. Typically, these documents consist of hardware and software installation guides, Cisco IOS configuration and command references, system error messages, feature modules, and other documents.

Documentation is available as printed manuals or electronic documents, except for feature modules, which are available online on CCO and the Documentation CD-ROM.

Use these release notes with the documents listed in the following sections:
