E1/T1 GSM Gateway / E1/T1 GSM Channel Bank
~Application 1: E1*2 in , GSM*31 out
When you do call terminal, DMT-2 can accept incoming call from 2 E1/T1 PRI and choose one GSM channel to dial out according to the prefix of the destination mobile number
~Application 2: E1*1 in, GSM*31 and E1*1 out.
DMT-2 is connected between PSTN and PBX using the E1/PRI interface. It routes the mobile calls from PBX through mobile channels instead of going directly to the PSTN, hence reduces higher rate charge for fix to mobile calls. If the call is not a mobile call, it just goes directly to the PSTN. On the other side, the calls come from PSTN will be passed to the PBX. Thus the DMT-2 can perform the LCR(Least Cost Route) function. (More detail as follows) |
