These release notes describe new features for the Cisco AS5800 universal access server that support Cisco IOS Release 12.0 T, up to and including Release 12.0(2)T. These release notes are updated with each maintenance release of the Cisco IOS software, which is typically every 6 weeks.
Use these release notes in conjunction with the cross-platform Release Notes for Cisco IOS Release 12.0 T located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
For a list of software caveats that apply to Release 12.0(2)T, refer to the "Caveats" section.
These release notes discuss the following topics:
The Cisco AS5800 is a high-density, ISDN and modem WAN aggregation system that provides digital and analog call termination. It is intended to be used as a service provider dial point-of-presence (POP) or centralized enterprise dial gateway. The Cisco AS5800 consists of a dial shelf, a router shelf, and a system controller:
The Cisco 5814 dial shelf and host Cisco 7206 router shelf communicate over a a dial shelf interconnect cable (DSIC). This nonblocking interconnect supports 10 Mbps, full-duplex data transfer. Data is converted into packets by the feature cards, transmitted to a hub on the dial shelf controller (DSC) card, and from there sent to the router shelf. Conversely, packets from the router shelf are sent to the DSC card, where they are transmitted over the backplane to the modem and trunk cards.
The AC-input power shelf is an optional component of the Cisco AS5800 Universal Access Server and is used to convert AC-input power into DC-output power for the DC-powered Cisco 5814 dial shelf. The AC-input power shelf contains two AC-input power supplies.
The Cisco AS5800 Universal Access Server accepts AC-input power via a separate, self-contained AC-input power shelf, which converts AC-input power into DC-output for use by the DC-powered dial shelf. The AC-input power shelf is rack-mounted and has a safety cover that shields the electrical connections in the power shelf rear.
The AC-input to DC-output connection supplies -48V DC-output power to the dial shelf power entry modules (PEMs). The PEMs receive the -48 volts and transmit power to the filter module. Power flows through the filter module to the backplane where it is distributed to the dial shelf controller card(s) and feature cards.
The AC-input power shelf includes two 2,000-watt AC-input power supplies that plug into a common power backplane in the AC-input power shelf. A single AC-input power supply is capable of powering a fully configured Cisco 5814 dial shelf. The second power supply provides full redundancy.
For more information on the Cisco AS5800, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (Document Number DOC-5800-SICG) or the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (Document Number DOC-5800-HICG) that shipped with your system.
This section describes the system requirements for Release 12.0(1) and includes the following sections:
Table 1 describes the memory requirements for the Cisco AS5800 feature sets supported by Cisco IOS Release 12.0 T. Flash memory is optional for these Cisco AS5800 images.
| System Components | Feature Set | Image Name | Required Flash Memory | Required DRAM Memory | Runs From |
|---|---|---|---|---|---|
Cisco AS5800 Router | IP Plus | c5800-p4-mz | 16 MB Flash | 64 MB DRAM | RAM |
Dial Shelf: Cisco 5814 | IP Plus | dsc-c5800-mz | 8 MB Flash | 32 MB DRAM | RAM |
System Controller: Cisco 3640 | IP Plus | c3640-c2is-mz | 16 MB Flash | 64 MB DRAM | RAM |
The Cisco AS5800 universal access server includes:
Cisco IOS Release 12.0 and later includes bundled modem code, which is the firmware or portware that runs on the Microcom 12-port and MICA 6-port modem cards. Modem code is bundled with the Cisco IOS software image to eliminate the need to store separate modem code. When the access server starts, the Cisco IOS software unpacks the modem code and loads the proper code on the modem cards. Table 2 lists the current bundled modem code versions.
| Modem Module | Current Bundled Modem Code Version | Minimum Cisco IOS Software Release |
Microcom modems | Microcom version 3.1.30 | 11.3(3)T and later |
MICA modems | MICA portware version 2.3.1.0 | 12.0(2)T and later |
The show modem mapping command lists all versions of modem code running on the modem modules, residing in system Flash memory, and bundled with Cisco IOS software. Enter this command to help you decide if you need to update your modem code files.
The modem code release notes are on CCO and on the Documentation CD-ROM.
To determine the version of Cisco IOS software running on your Cisco AS5800 universal access server, log in to the access server and enter the show version user EXEC command:
router> show version
The following is sample output from the show version command. The version number is indicated on the second line as shown below:
Cisco Internetwork Operating System Software IOS (tm) 5800 Software (C5800-p4-mz), Version 12.0.......
Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.
The Cisco AS5800 universal access server contains multiple Cisco IOS software images. Four images are required to run the entire system (see Table 3 ). However, only the first three software images listed require part numbers for ordering.

This section lists the new features supported by the Cisco AS5800 for Cisco IOS in Release 12.0(2)T.
The following new features for the Cisco AS5800 universal access server are available for
Cisco IOS Release 12.0(2)T. Documentation is provided separately for these features.
R2 signaling is an international signaling standard that is common to channelized E1 networks. However, there is no single signaling standard for R2. The ITU-T Q.400-Q.490 recommendation defines R2, but a number of countries and geographic regions implement R2 in entirely different ways. Cisco Systems addresses this challenge by supporting many localized implementations of R2 signaling in its Cisco IOS software.
Cisco System's E1 R2 signaling default is ITU, which supports the following countries: Denmark, Finland, Germany, Russia (ITU variant), Hong Kong (ITU variant), and South Africa (ITU variant). The expression "ITU variant" means there are multiple R2 signaling types in the specified country, but Cisco supports the ITU variant.
The following new features for the Cisco AS5800 universal access server are available for Cisco IOS Release 12.0(1)T. Documentation is also provided for these features.
The Command Line Interface (CLI) String Search feature allows you to search or filter any show or more command's output. This is useful when you need to sort though large amounts of output, or if you want to exclude output that you do not need to see. CLI String Search also allows for searching and filtering at --More-- paging prompts.
With the search function, you can begin unfiltered output at the first line that contains a regular expression you specify. You can specify a maximum of one filter per command to either include or exclude output lines that contain the specified regular expression.
A regular expression is any word, phrase, number, or other type of information that appears in show or more command output.
With the introduction of Easy IP Phase 2, Cisco IOS software also supports Intelligent DHCP Relay functionality. A DHCP Relay Agent is any host that forwards DHCP packets between clients and servers. A DHCP Relay Agent enables the client and server to reside on separate subnets. If the Cisco IOS DHCP server cannot satisfy a DHCP request from its own database, it can forward the DHCP request to one or more secondary DHCP servers defined by the network administrator using standard Cisco IOS ip helper-address functionality.
Layer Two Tunneling Protocol (L2TP) is an emerging Internet Engineering Task Force (IETF) standard that combines the best features of two existing tunneling protocols: Cisco's Layer Two Forwarding (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP). L2TP is an extension to the Point-to-Point Protocol (PPP), which is an important component for Access Virtual Private Networks (VPNs). Access VPNs allow mobile users to connect to their corporate intranets or extranets, thus improving flexibility and reducing costs.
Traditional dial-up networking services only supported registered IP address, which limited the types of applications that could be implemented over Virtual Private Networks (VPNs). L2TP supports multiple protocols and unregistered and privately administered IP addresses over the Internet. This allows the existing access infrastructure, such as the Internet, modems, access servers, and ISDN terminal adaptors (TAs), to be used.
L2TP can be initiated wherever PPTP or L2F is currently deployed and can be operated as a client initiated tunnel, such as PPTP, or a network access server (NAS) initiated tunnel, such as L2F.
