Intelligent routing
Bi-directional bridge bet-
ween ISDN BRI and GSM
networks, the QuesCom 50
can route calls from one of
these networks to the other
one in the two directions
according to advanced rou-
ting rules.
Thus, if all of the GSM mod-
ules are busy, the QuesCom
50 can be configured to
send overflow calls to the
fixed network.
Capacity and 
interoperability
The QuesCom 50 has 2 bi-
band GSM channels
enabling  2 GSM simultane-
ous calls to mobiles.
Each channel supports 900
and 1800Mhz SIM types
from different operators.
Equipped with 2 ISDN ports
and 1 “Synchro” port, the
QuesCom 50 interoperates
with all BRI ports of ISDN
No need to touch
PBX. All operations
are transparent.
This makes installa-
tion a snap.
