About the Rear Panel LED Operation
Green: Normal operation
Red Alarm
or Loss of signal (LOS) indicates that there is
no signal and thus no framing info received. A defect or
unplugging the PRI cable will produce the same effect.
Yellow Alarm
or
Remote Alarm Indicator
(RAI) means that the
Entrypoint is receiving framing info, but in this framing info
the other side tells the Entrypoint that it is not reading the
Gateway's transmitted framing info. Typically, this may be a
broken connector in the transmit (TX) part of the PRI cable.
This could also indicate weak or noisy signal in the transmit
(TX) part of the PRI cable.
Blue Alarm
indicates that the received frames are not
synchronized properly.
No LED's
illuminate, indicates that layer one framing is
working (right protocol like for example EURO ISDN selected),
however there is a problem at layer 2 caused by for example
a CRC4 configuration mismatch.
