Description

Overview

The Cisco 2500 Series Router model 2523 is a versatile, high-performance router designed for small to medium sized networks that still rely on legacy Token Ring and ISDN connections. This single-slot router combines a Token Ring interface, a 10-Mbps Ethernet port, a serial interface and an ISDN BRI port in a compact chassis, making it an ideal bridge between older network technologies and modern IP-based environments.

Key Features

Integrated Token Ring (802.5) interface for legacy LAN support
10-Mbps Ethernet port for fast LAN connectivity
Serial interface for WAN links such as T1/E1
ISDN BRI port for voice and data over ISDN lines
Modular software architecture with IOS for flexible routing protocols
Built-in security features including ACLs and basic firewall capabilities
Compact 1U rack-mountable design for space-constrained installations

Technical Specifications

Model/Part Number: 2523
Processor: 16 MHz 68EC030
Memory: 8 MB RAM, 2 MB flash
Interfaces: 1 Token Ring (4 Mbps), 1 Ethernet (10 Mbps), 1 Serial (V.35), 1 ISDN BRI
Operating temperature: 0 to 40 deg C (32 to 104 deg F)
Power supply: 110/220 V AC, 50/60 Hz
Dimensions: 1.75 in (height) x 17.5 in (width) x 13.5 in (depth)
Weight: 7 lbs (approx)

Applications

This router is well suited for organizations that need to maintain Token Ring segments while transitioning to Ethernet, remote offices that use ISDN for voice and data, and sites that require a reliable serial WAN connection. Typical deployments include:

Legacy corporate LANs that still operate Token Ring devices
Branch offices with limited broadband options relying on ISDN
Small data centers that need a cost-effective edge router
Educational institutions with mixed network environments
Industrial sites where rugged, compact routing hardware is required

By integrating multiple interface types into a single platform, the Cisco 2523 simplifies network architecture, reduces cabling complexity, and provides a reliable bridge between old and new technologies.
