Cisco AS5200 Universal Access Server Overview
The Cisco AS5200 access server is a versatile data communications platform that provides the functions of an access server, a router, and digital modems in a modular chassis.
The Cisco AS5200 provides the greatest benefit for mid-sized organizations that need to centralize processing capabilities for mobile users and telecommuters.
The Cisco AS5200 is optimized for high-speed modem access and is ideally suited for all traditional dial-up applications, such as access to a host, electronic mail, file transfer, and dial-in access to a LAN.
The Cisco AS5200 accommodates up to three feature cards---one or two WAN cards and one or two modem carrier cards. The choice of cards is as follows:
A blank slot cover is installed over any unused slots.
The Cisco AS5200 can be managed with software ranging from a simple terminal command line interface for device configuration to a simple network management protocol (SNMP) network manager. For more information about managing the Cisco AS5200 using a network manager, refer to the Cisco AS5200 Manager Guide publication.
The Cisco AS5200 access server consists of the following components:

Two Cisco AS5200 power supplies provide AC or DC power input and supply DC power to the installed cards via connectors in the backplane. Either the AC or DC power supply is required in the chassis.
The Cisco AS5200 can contain 12, 24, 36, or 48 modem ports installed on two carrier cards in the chassis card slots. Each modem carrier card can hold two 12-port modem cards. The modem cards connect through the carrier card and the system backplane to the dual T1 PRI card. Transmission or reception is then accomplished on T1 lines connected to the dual T1 PRI card.
Each modem supports V.42bis data compression and uses the Hayes Smartmodem AT and V.25bis command sets. The Microcom Networking Protocol (MNP) and V.42 error-correction protocol standards provide error-free performance. The modem offers MNP Class 10 with Adverse Channel Enhancements (ACE). MNP 10 includes:
Each modem supports the following protocol and modulation standards:
The dual T1 PRI card routes incoming digital T1 lines to the modem cards. The dual T1 PRI card provides RJ-48C connector(s) to terminate at the trunk(s). The dual T1 PRI card performs all necessary autoequalization and autogain functions to support 6000 feet of 24-gauge shielded cable. This card complies with all Bell Core standards relating to T1 (ANSI T1.403) alarms, loopbacks, error detection, and so forth. The dual T1 PRI card is equipped with an integrated CSU.
The dual T1 PRI card handles up to 48 digital signal level 0 (DS-0) channels from two trunks. Each channel carries either a pulse code modulation (PCM)--encoded voice channel or digital data. The dual T1 PRI card supports 64-kbps clear channel operation for data channels and feature group B operation for voice channels.
The dual T1 PRI card allows the Cisco AS5200 to use DNIS and ANI information provided by the public 950 services, feature groups B and D, and enhanced 800 services to route data. With this call information, the Cisco AS5200 independently routes the individual DS-0 channels of the T1 signal to specific modems.
The specifications of the Cisco AS5200 are listed in Table 1-1.
