Chapter 2: AI2524 Overview

Introduction

This chapter describes the Cisco IOS software features and the AI2524 hardware specifications. The AI2524 multi-protocol router adds the Cisco Internetworking Operating System (IOSTM) routing software to the NEBS compliant AISwitch 180 Series. The AI2524 adds leading edge routing capabilities through TCP/IP and OSI networks to the AI 180 Switch protocol conversion and data port concentration capabili- ties.

The AI2524 is designed for reliable connectivity to a Wide-Area Net- work (WAN). It can provide WAN/DCN connections to centralized operations support systems from central office based LAN/LCN or X.25 networks.

The AI2524 has one Ethernet LAN interface with both a backplane (IRB) port and a 10BaseT port on the front panel. The backplane port provides connections to a large number of interfaces and protocols through a variety of AISwitch interface modules.

The base module accepts two serial interface modules in any combi- nation. The three available modules are:

T1 CSU/DSU

The AI2524-T1 module is an integrated CSU/DSU that supports full or fractional T1 leased line services. It may be remotely managed using Simple Network Management Protocol (SNMP)

Four Wires 56K CSU/DSU

The AI2524-4W56 module is an integrated CSU/DSU that supports

4-wire 56k leased line or switched services. It may be remotely man- aged using Simple Network Management Protocol (SNMP)

5-IN-1 Serial Cable Interface

The AI2524-5N1 module provides a cable interface to a synchronous serial line. It supports full and half duplex operations up to 2.048 MHz, full duplex. Dependent upon the interface, DTE/DCE and NRZ/NRZ1 operations are available. Cables are available for the these interfaces:
