Connector/Indicator Function

RX-TX Female DB-15 connector for XMT and RCV E1.

RX BNC connector for receive E1 line.

TX BNC connector for transmit E1 line.

LOS light (red) Indicates loss of signal at the local end.

Red alarm light Indicates loss of local frame alignment. On an NTM, Red indicates loss of packet

alignment.

Yellow alarm light Indicates loss offrame alignment at remote end. Onan NTM, Yellowalarm indicates loss of

packet alignment.

AIS light (green) Indicates the presence of all ones on the line.

MFRA light (red) Indicates loss of multiframe alignment (E1 only).

MFYA light (yellow) Indicates loss of multiframe at remote end (E1 only).

Fail light (red) Indicates an error. Reset the card withresetcd f. If the LED comes on again, call the TAC.

Active: light (green) Indicates the card is in service with active circuits.
