TANDBERG ENTRYPOINT USER GUIDE
About the Rear Panel LED Operation | Connectors, Switches, Display, and Buttons |
•Green: Normal operation.
•Red Alarm or Loss of Signal (LoS) indicates that there is no signal and thus no framing information received. A defective or unplugged 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 information. 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.
