Since many networks have their own “personality”, performing first time configuration of the remote
communication sometimes requires tweaking of the modem parameters.
This section describes some trouble shooting techniques if configuring the repeater for remote access
fails.
The illustration below is a simplified schematic of the remote communication between a GSM
modem in a repeater and an analogue modem. The analogue modem in the computer communicates
with the Interworking Function Unit (IFU), which is the GSM network analogue network interface.
The call is routed via the switch centre over the air interface to the data call number in the SIM-card
of the GSM module.
The Control Module is responsible for establishing connections with the Axell Element Manager, and
to answer incoming calls to the repeater.
As described in previous sections, the Control Module only accepts one login at a time, either via
Local Maintenance port (LMT) or modem connection. Hence, when verifying the remote access of
the repeater, it is important to log out from the repeater locally before trying to access the repeater
remotely.
