USER GUIDE

The PRI status indication consist of 3 fields (see

About the Rear

Panel LED Operation

below for PRI status):

Active – Indicates weather the PRI port is active or not.

Total number of channels – indicates the maximum available

number of simultaneous ISDN slots (calls) per port; typically
30 for an E1 PRI and 8 for an E1 BRI.

Number of free channels – indicates the number of free B-

channels on ISDN.

To view the ISDN PRI status, select the

ISDN status

item of

the Status tab.

About the Rear Panel LED Operation

In addition to the web page indications, the ISDN interface also
contains 4 LEDs, located at the the Entrypoint rear panel.
These LEDs indicate the following PRI status:

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.
