DTM-V VoIP GSM Channel Bank

DMT-V: 8/16/24/31 ports VoIP GSM Gateway (support SIP and H.323)
~ with CDR,LCR,Remote Monitor
~ GSM ,CDMA can be combined in one DMT-V

DMT can provide Call Detail Record (CDR) for traffic and accounting management. User can remote monitor traffic via VNC

DTM E1 PRI GSM Channel Bank

DMT accepts incoming call from E1/T1 PRI of PSTN or PBX and choose one GSM channel to dial out according to the prefix of the destination mobile number. In this way, we can have least cost routing. DMT can provide Call Detail Record (CDR) for traffic and accounting management.
*Besides PRI to GSM,you maybe also apply GSM to PRI (two ways).
GSM Frequecny:
Quad Band:900/1800/1900/850MHZ

DTM-2  E1 PRI 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)
