Note that following alarms can be indicated by LP/ALM blinking on: LOS, OOF, AIS, RED, FERF.

Note：if atm interface is shutdown, both LINK/ACT and LP/ALM will be off.

4.12.4 Interface Cable

The interface that the Router 1-Port T3 ATM FIC provides uses two SMB sockets for data transmitting and receiving respectively. The ports adopt the 75-ohm unbalanced transmission mode and are connected to the peer device using a pair of 75-ohm unbalanced coaxial cables as shown in Figure 4-38.Several cable length options are available.

Note:

The Router 1-Port T3 ATM FIC and 8.8 Router 1-Port E3 ATM FIC cards use the same type of cables for connection, which are called E3/T3 cables in this manual.

4.12.5 Connecting the Interface Cable

Caution:

By design, the Router 1-Port T3 ATM FIC is protected against lightning strikes. But when outdoor cabling is involved, you are recommended to add a special lightning arrester at the input end of the E3/T3 cable for better protection.
