MIM-1ATM-OC3
Introduction
The 1-port ATM (Asynchronous Transfer Mode) 155 Mbps optical interface module (MIM-1ATM-OC3)
provides ATM interfaces for routers. It provides the following features:
• Two frame formats: SDH STM-1 and SONET OC-3;
• Scrambling in data transmission;
• Both line clock (when working as DTE interface), and internal clock (when working as DCE
interface);
• Three types of test measures: local cell loopback, local payload loopback, and remote
loopback.
