Digital Mobile Trunk -DMT
Product Model: DMT
Introduction

E1 / T1 PRI ISDN GSM Gateway also known as GSM Channel Banks / GSM Multiplexers / Digital Mobile Trunk (DMT).It accepts incoming call from E1/T1 PRI of ISDN or PBX and chooses one GSM channel to dial out according to the prefix of the destination mobile number. In this way, we can have least cost routing (LCR). DMT can provide Call Detail Record (CDR) for traffic and accounting management.

A compact E1 / T1 PRI ISDN GSM Gateway / GSM channel bank digitally integrates the wireless GSM interfaces and the E1 / T1 interface, therefore no additional GSM equipment is required to connect the T1 to the local GSM wireless network. It provides superior voice technology and enables up to 30 simultaneous calls.

This device is an ideal solution for Call Centers, large organizations with high call traffic to GSM networks or alternative carriers as a call termination tool and corporate head offices with a VoIP network linking remote sites.
 

Feature

1. Each E1 channel will connect to the corresponding output GSM Port.

2. 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. 

3. Hiding the Caller ID:
user can choose whether to hide the CLID of the GSM port or not.

4. 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 (SIM card extender) is installed).

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

6. Backup of CDR:
user can set up the path of CDR backup.

7. Simulate ring back tone:
user can set up whether to simulate ring back tone or not.

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

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

10. VoIP Application:
Gateway's E1/T1 port connects DMT's E1/T1 port.
