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 access server provides the greatest benefit for mid-sized organizations that need to centralize processing capabilities for mobile users and telecommuters.
The access server 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 access server accommodates up to three feature cards---one WAN card 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 access server 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 access server using a network manager, refer to the Cisco AS5200 Manager Guide publication.
The access server consists of the following components:

Two 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 access server can contain 12 to 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 dual E1 PRI card includes an 12-port modem card for a configuration of 60 modems required by two E1 PRI lines.
The modem cards connect through the carrier card and the system backplane to the dual T1 PRI or E1 PRI card. Transmission or reception is then accomplished on T1or E1 lines connected to the dual T1 PRI or E1 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 the trunk(s). The dual T1 PRI card performs all necessary equalization and gain functions to support 6000 feet of 24-gauge unshielded cable. This card complies with all Bell Core standards relating to T1 (ANSI T1.403) alarms, loopbacks, and error detection. 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 or voice channels and feature group B operation for voice channels.
The Dual E1 PRI card is installed in the access server to provide physical termination for two E1 PRI lines. The card is designed to support the E1 cable standard of 30 Bearer (B) channels for voice and data, one Data (D) channel for signaling, and one channel for framing. Each channel transmits at up to 64 kbps for a combined total of 2.048 Mbps for each E1 PRI line. The rear panel of the Dual E1 PRI card is shown in Figure 1-3.

The access server is used to service calls from users accessing remote services using a variety of network protocols. Calls are terminated in the access server through 60 modems installed in the chassis. User data can then be routed through the Ethernet or synchronous serial ports on the access server chassis.
The following list describes the features of the Dual E1 PRI card:
The specifications of the access server are listed in Table 1-1.
