2N - ISDN BRI GSM Enterprise Gateway
4.3. 2N – ISDN BRI GSM Enterprise Point-to-Multipoint
Connection
All terminals (connected to the same NT, TE) must be connected
with non-crossed four-wire cables. If you connect a remote ISDN
terminal, terminate the bus with a terminating circuit (see Fig. 24).
Each ISDN telephone connected to the subscriber bus can call
to the GSM network via the GSM gateway using the GSM
gateway DDI.

4.4. 2N – ISDN BRI GSM Enterprise as Pass-Through
Router
Fig. 25 shows how to save one BRI port to the PBX where the
GSM gateway is set to operate as a pass-through gateway with
respect to incoming calls while outgoing calls are routed according
to the ISDN BRI GSM gateway LCR table.
Fig. 26 shows the ISDN BRI GSM gateway as a pass-through
router for a Point-to-Multipoint connection. Calls are routed
automatically to the GSM network or ISDN according to the GSM
gateway LCR table. The GSM gateway DTMF is not needed
in this arrangement.
