Applications

This module was used in enterprise ATM switching environments, particularly in telecommunications and data center infrastructure from the 1990s through early 2000s. The MCP function manages control and signaling for the switch fabric, while the 4-port module handles ATM cell switching. These systems supported legacy telecom networks and high-speed data switching before Ethernet dominance.

Condition: Used
This Bay Networks Nortel 5724M ATM Switch MCP Host Module was pulled from a working network environment and has been visually inspected. The PCB and components appear to be in good condition with no obvious physical damage. The faceplate shows light wear consistent with rack service. The board carries date codes of 9729–9730, placing manufacture in late 1997. No bench-testing has been performed at our facility. Module only — no chassis or cables are included. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
