Avaya M5502-AOC12MMF ATM OC12 Interface Module

Avaya M5502-AOC12MMF is an ATM OC12 interface module for Avaya-Lucent P550 ATM switches within the M5500 family. It provides an OC12 multimode fiber ATM interface to connect the P550 switch to ATM networks, enabling OC12-rate transport over MMF fiber. The module is listed under part numbers such as 530-0058-566 and appears in Avaya-Lucent catalogs as M5502-AOC12MMF for the P550 ATM OC12 interface. Designed for integration into the M5500-series backplane, it serves as the high-capacity link between the P550 and OC12 networks, suitable for enterprise backbone or telecom-edge deployments that rely on ATM services over multimode fiber. The MMF designation confirms multimode fiber compatibility and OC12 transport within the Avaya Lucent platform. Common applications include linking a P550 ATM switch to an OC12-based backbone or access network to carry ATM traffic for legacy services alongside newer network frameworks.
