The following is a diagram of the end of the TE1 card identifying the LEDs on the card.

LOS
This LED has the following states:
Off No LOS alarm condition
On This could mean the line is disconnection or the receive signal level is too low. The port may be configured for short haul when it should be set for long haul. Note TE1 will transmit a Remote Alarm Indication (RAI) to the remote end in response to a LOS or LFA (Loss of Framing Alignment).

RRA
This LED has the following states:
Off No RRA alarm condition
