Tip
For an external synchronisation line you can use a standard
cable with an RJ45 connector. To disconnect the Rx wires just
release the defined jumpers on the PRI 2 interface on the PRI
board.
Simultaneous Use of PRI ISDN and VoIP Cards
The GSM gateway enables the VoIP and PRI ISDN interfaces to be used at the same
time. This configuration requires additional incoming/outgoing call routing settings.
Figure: Installation with SIP proxy (Cisco Call Manager).
Licence Limitations
Some of the 2N products have time–limited software licences (e.g. DSS1 signalling,
etc.). Moreover, every gateway restart adds one hour to the internal licence counter.
To see the current licence status, use the CPU web interface (the standard licence
validity is 850 hours).
You are recommended to contact your dealer before licence expiration to request for a
new licence key to increase the gateway using time.
To upload a new licence code, use the CPU web interface.
Caution
A gateway with an expired licence fails to accept calls from the
VoIP/GSM/UMTS/PRI interface because the call control layer is
deactivated.
