The following table describes the LEDs on the card panel.

Table 16 LED description of 1-port T3 FIC

LINK	OFF means the link is not connected and ON means the link is connected.
ACT	OFF means no data is being transceived on the interface and blinking means data
	is being transceived.

Interface Cable 1-port Channelized T3 FIC and 1-port E3 FIC use the same type of interface cables and make the connection in the same way.

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.
