Ensure a successful configuration by observing the modem LED as described below.
For GSM modem LED descriptions, refer to
0 4.1.
Verify the remote communication either by having someone attempting to integrate the repeater
from the Axell Element Manager, or by dialing the repeater using the Repeater Maintenance Console.
NOTE: It is very important to dial the data number of the SIM. In case the voice number is dialled, the call is
answered, but almost immediately the call will be hung up.
3.10.2.5 SIM-card Using Single Numbering Scheme
If the network is configured using Single Numbering Scheme (SNS), some special considerations
apply.
The repeaters are by default configured so that networks using SNS always will have calls routed to
the data service in the modem. When dialling from within the network to a repeater having an SNS-
configured SIM will operate normally, since the call originator informs the system that the bearer is
of type DATA. However, when dialling from outside the network trying to connect to the repeater can
be difficult. Depending on the interface to the roaming network or to the PSTN network if an
analogue modem is used, the bearer type can default to voice. If the bearer is set to voice, the data
service cannot be converted to DATA, and a call setup cannot be completed.
NOTE: This is not a repeater related problem; the solution is to verify how the external network interfaces
handles the VOICE vs. DATA bearer type.
3.10.3 Communication via PSTN (Fixed) Modem
Also for PSTN modems data call shall be used.
