Digital Mobile Trunk (DMT) accepts incoming call from E1/T1 PRI of PSTN or

PBX (or VoIP) and choose one GSM/CDMA/UMTS 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.

*ISDN PRI interface: 1 port (or VoIP Card)

*GSM/CDMA/UMTS interface: 31 ports

*Optional external SCE-900: Expands SIM card upto 32 pieces per GSM/CDMA/UMTS channel.

*Optional external SCBox: Expands SIM card upto 4 pieces per GSM/CDMA/UMTS channel.

*each E1/VoIP channel will connect to the corresponding output GSM/CDMA/UMTS Port.

*Auto-routing for the same network: system will search for the GSM/CDMA/UMTS port of the same network to dial out, according to the prefix of the out-dialing number from the incoming E1/VoIP channel.

*Password validation: operator has to input the correct password for further setup of the system parameters.

*Hiding the CLID: user can choose whether to hide the CLID of the GSM/CDMA/UMTS port or not.

*Calling time: user can assign the calling time for each sheet of the SIM card. When the time runs out, system will block this GSM/CDMA/UMTS port, or switch to next unused SIM card (in the case that SCE is installed).

*Call detail record (CDR): the CDR is provided for further use of the billing system.

*Backup of CDR: user can set up the path of CDR backup. Simulate ring back tone: user can set up whether to simulate ring back tone or not.

*SCE test: system can auto-test the SIM card switching function to ensure the successful switchover without letting the SIM card be used repeatedly.

*ASR statistics: system will provide a time-varying ASR analyzing report for easy understanding the communication traffic.

*PRI(or VoIP) to GSM/CDMA/UMTS,GSM/CDMA/UMTS to PRI(or VoIP) (two ways).

*If you want to connect extra Outdoor directional antenna or Yigi antenna,you can purchase option Antenna Combiner(AC-32)

*If your control room is usually no body there,you can consider our smart power monitor.

It can remote power on/off ,reboot via PSTN or WEB.
