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 3G Gateway rear panel.
These LEDs indicate the following PRI status:
•
G r e e n : 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 3G Gateway is receiving framing info, but in this framing
info the other side tells the 3G Gateway 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.
