4.1.6.1 Description of PRI Alarms

A PRI cable consists of four wires (2 pairs of wires): One pair for Transmit (TX) and one pair for Receive (RX) signals.

Red Alarm

Red alarm or Loss of signal (LOS) means that there is no signal and thus no framing info received. (This has same effect as pulling out the PRI cable).

Yellow Alarm

Yellow alarm or Remote Alarm Indicator (RAI) means that the TANDBERG Gateway is receiving framing info, but in this framing info the other side tells the TANDBERG Gateway that it is not reading the TANDBERG Gateway’s transmitted framing info. Typically, this may be a broken connector in the TX part of the TANDBERG Gateway PRI cable. This could also indicate weak or noisy signal in the TX part of the TANDBERG Gateway PRI cable.

Blue Alarm

Blue alarm means that network on the far side of the CSU is unavailable.
