the program will route the call accordingly, to the operator of the
PBX, to a certain local extension or will provide DISA tone.
DISA – direct inward access – alows callers to select the extension
they want without help from an operator, via DTMF codes. Also, they
can dial out of the exchange.
If the incoming ID is missing, the default routing options apply.
With the “Nr. of Dialed Digits” option MobiLInk makes the call
immediately after receiving the last digit, any digit sent afterwards
will be ignored.
5.2. Modes of connection
Here you have a few examples of connecting the MobiLink
equipment to an ISDN phone exchange.
The ISDN 2 GSM interface can be connected either as TE, when it
acts as a terminal equipment, or as NT, when it simulates ISDN
network.
Also, it may be used as a pass-through device that is “transparent”
for the calls. In this case the MobiLink ISDN 2 GSM equipment is
inserted between the public ISDN network and the PBX.
These three basic modes of connecting MobiLink can be combined
in different ways, as shown further.
5.2.1 MobiLink connected via NT to a TE junction of the
PABX
NT connector of the GSM-2-ISDN linked to TE of the PABX, TE of
the PABX goes to the public ISND. You may use the TE interface
to get the clock signal for synchronization, as shown below.
