ATM interface cards (including 1-port OC-3 ATM MM SC, 1-port OC-3 ATM SM
SC 15km, and 1-port OC-3 ATM SM SC 30km) function in the system primarily to
provide ATM interfaces for the Router. 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.
