Outgoing from PABX
The PABX unit verifies the number dialed and routes the call for the
public network thru the dedicated interface and the call for the
mobile network thru the MobiLink's NT interface. The MobiLink unit
selects one mobile network operator to send the call.
Incoming to PABX
Calls get into PABX via TE connector. When an incoming GSM call
comes in, if the setting in the GSM window is Operator, the call will
go to the local extension from Target. From the PABX the call is
considered to be a local call!
If the setting is DISA, the caller gets a DISA tone and he can dial
any local subscriber he wishes. Also, he can make calls from the
public network, acting as a local subscriber.
5.2.3 MobiLink connected to PBX on NT interface and to
public ISDN via TE interface
The public ISDN network is connected directly to the Topex
MobiLink equipment via TE interface. The NT connector is used to
link to a TE junction of the PABX.
