DMT: E1 PRI / T1 PRI GSM / CDMA Channel Bank
DMT and DMT-V can combine GSM and CDMA in one device
Interface:
( 1) E1 PRI or T1 PRI interface that you can connect with PBX or PSTN or Trunk gateway
( 2) GSM*31 or CDMA2000 (800mhz) *31
DMT-V: 30 ports VOIP GSM / CDMA Gateway
~Interface: (1) VOIP Card (support SIP and H. 323) , (2) GSM*31 or CDMA2000 (800mhz) *31
~ provide CDR
~ Has LCR
~ 4 sims / 32 sims per GSM Channel
~ SMS sending and receiving
~ Use AT Command to send USSD
~ Support Remote Monitor traffic via VNC
DMT accepts incoming call from E1 / T1 PRI of PSTN or PBX or VOIP 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.
* ISDN PRI interface: 1 port or VOIP Card*1
* GSM interface: 31 ports
* Optional external SCE-900: Expands SIM card upto 32 pieces per GSM channel.
* each E1 channel will connect to the corresponding output GSM Port.
* Auto-routing for the same network: system will search for the GSM port of the same network to dial out, according to the prefix of the out-dialing number from the incoming E1 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 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 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.
