Introduction
The Cisco AS5800 access server is a high-density, Integrated Services Digital Network (ISDN), and modem Wide Area Network (WAN) aggregation systems that provide digital and analog call termination. They are 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 and one or two router shelves:
•
The Cisco DS5814 (dial shelf) has 14 slots and can support 1 or 2 dial shelf controller cards and up to 12 feature cards to provide full analog modem, and ISDN coverage. Analog calls are terminated by a feature card that is loaded with integrated modems.
ISDN calls are terminated onboard the trunk card on High-Level Data Link Control (HDLC) controllers. The E1 trunk, T1 trunk, and the CT3 trunk cards include channel service units (CSUs) and have either 12 E1 ports, 12 T1 ports, or 28 T1 ports (within the CT3 trunk) that can operate as Primary Rate Interfaces (PRIs), inter-machine trunks (IMTs), or channelized interfaces in any combination. The specific trunk card limitations are described in Table 2, Part 1.
Note
T1 and E1 cards are not supported in the same box.
•
The Cisco RS7206VXR (router shelf) contains a network processing engine, an I/O controller, and the egress interfaces, such as High-Speed Serial Interface (HSSI), Fast Ethernet (FE), Gigabit Ethernet (GE), and Asynchronous Transfer Mode (ATM), and supports either 280W AC-input or 280W DC-input redundant power. The router shelf also may contain one or two dial shelf interconnect port adapters each with a single RJ-45 receptacle, which is used to connect the router shelf to the Cisco 5814 dial shelf. The interconnect port adapter connects directly to the dial shelf controller card on the dial shelf via a Cisco-proprietary cable, customized with jack screws to secure the connection. You must use this specially designed cable that ships with your interconnect port adapter. Each router shelf can only be connected to one dial shelf controller card.If the dial shelf configured in split mode, it must be connected to two separate router shelves.
Note
The router shelf is only supported for routing data to and from the dial shelf. The router should not be used with multiple port adapter interfaces to route LAN traffic between multiple networks.
The AC-input power shelf is an optional component of the Cisco AS5800 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 AC-input to DC-output connection supplies -48V DC-output power to the dial shelf power entry modules (PEMs). The PEMs receive the -48V 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 W, 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.
Cisco AS5800/Voice Gateway
The Cisco AS5800/Voice Gateway enables highly scalable deployment of toll-quality voice and fax services over data networks. Enhanced with Cisco's IOS software and Service Node (SN) capabilities, the Cisco AS5800 supports features such as prepaid and postpaid calling card, 800 call redirect, voice activated dialing, and voice and fax mail.
The Cisco AS5800 is specifically designed to meet the demands of large service providers such as Post, Telephone, and Telegraphs (PTTs), regional bell operating companies (RBOCs), inter-exchange carriers (IXCs), and large Internet telephony service providers (ITSPs). The physical architecture of the Cisco AS5800 product enhances reliability, availability, and serviceability. Critical features to dial POP administrators include minimizing downtime, service costs, and time to deployment.
The Cisco AS5800 supports up to 2016 ports in a single system, thus offering the highest concentration of VoIP Digital Signal Processors (DSPs) available in a single voice gateway. The Cisco AS5800 offers breakthrough voice quality, density, and scalability, while continuing to provide the rich set of access, VoIP, and QoS services that are part of Cisco IOS software.
For more information on the Cisco AS5800, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-5800-SICG) or the Cisco AS5800 Universal Access Server Hardware Installation Guide (DOC-5800-HICG) that shipped with your system.

RS7206 (NPE-200 based) Router Shelf
With any Cisco AS5800 software image, the maximum hardware configuration with an RS7206 is one CT3 or two T1/E1 trunk cards and three UPCs, five DMMs or 10 HMMs for a maximum of 28 24 T1 / 24 E1 controllers and 720 modems.
If a larger configuration is desired, a second RS7206 router shelf can be configured in split-shelf mode, or a single RS7206 VXR may be used to support up to 1344 modem sessions. Configurations above 1344 modem sessions require two RS7206VXR router shelves in split-shelf mode.
The Cisco AS5800/Voice Gateway can support 672 voice calls per RS7206VXR router shelf. 1344 voice calls require two RS7206VXR router shelves configured in split-shelf mode. RS7206 router shelves do not support voice services.
1 72-port modem card requires 32M DRAM.
2 144-port modem card requires 64M DRAM.
3 High-complexity voice cards (with codecs G.723.1, G.728, or G.729) require greater resources to perform complex coding and decoding that results in Voice-handling capacity reduction. Medium-complexity voice cards (with codecs G.711, G.726, or G.729a) can manage twice the number of Voice channels than high-complexity voice cards can.
Determining the Software Version
To determine the version of Cisco IOS software running on your Cisco AS5800, log in to the Cisco AS5800 and enter the show version EXEC command:
router> show versionCisco Internetwork Operating System SoftwareIOS (tm) 12.1 Software (c5800-p4-mz), Version 12.1(6), RELEASE SOFTWAREUpgrading to a New Software Release
For general information about upgrading to a new software release, refer to Upgrading the Cisco IOS Software Release in Cisco Routers and Modems located at:
http://www.cisco.com/warp/public/130/upgrade_index.shtml
Microcode and Modem Code Software
Microcode software images are bundled with the system software image—with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards.
You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.
The modem code release notes are on Cisco.com and the Documentation CD-ROM.

Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
CautionCisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Important Information
The following section contains important notes about Cisco IOS Release 12.1(6) that can apply to the Cisco AS5800.
Caveat CSCdr91706 and 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 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 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.
Enhancement to ppp ipcp Command
The ppp ipcp command, which supplies Domain Name System (DNS) or Windows Internet Naming Service (WINS) addresses during IP Control Protocol (IPCP) negotiation, has been enhanced with the reject and accept keywords. These keywords allow enabling or disabling support for the Microsoft IPCP extensions defined by RFC 1877.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats and select severity 3 caveats for Cisco IOS Release 12.1 and is located on CCO and the Documentation CD-ROM.
