5.7.5 Troubleshooting Remote Communication
Please also refer to the document Common Command and Attributes for guidance.
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.
