7.8 1ATM-OC3MM/1ATM-OC3SM/1ATM-OC3SML

7.8.1 Introduction

ATM interface modules (including 1ATM-OC3MM, 1ATM-OC3SM, and 1ATM-OC3SML)
function in the system primarily to provide ATM interfaces for the Eudemon200. They
can:
Support two frame formats, namely, SDH STM-1 and SONET OC-3.
Allow scrambling in data transmission.
Support both line clock (used when working as DTE interface) and internal clock
(used when working as DCE interface)
Support the test measures of local cell loopback, local payload loopback and
remote loop.
Note:
For the ATM interface configuration procedures, refer to Operation Manual.
