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 (IOS
TM
) 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:
