DMT là một E1 GSM Channel Bank / E1 GSM Gateway
- E1 PRI * 1 (T1 PRI * 1), GSM hoặc CDMA hoặc UMTS * 31 (hai chiều)
- GSM, CDMA có thể được kết hợp trong một DMT
DMT (kỹ thuật số di động liên tỉnh) là một kênh E1 GSM Bank chấp nhận cuộc gọi đến E1/T1 PRI PSTN hoặc tổng đài và chọn một kênh GSM để quay số ra theo các tiền tố của số điện thoại di động. Bằng cách này, chúng ta có thể định tuyến LCR. DMT có thể cung cấp Ghi lại chi tiết cuộc gọi (CDR) cho lưu lượng truy cập và quản lý kế toán.
Có thể ứng dụng cuộc gọi 2 chiều từ GSM đến PRI và ngược lại.
Tần số:
Quad Band:850/900/1800/1900MHZ
3G/UMTS: for all world and Japan (SoftBank Mobile,Docomo)
3G/UMTS Version: 3G:EDGE/GPRS 850, 900, 1800, 1900 MHz / HSDPA/UMTS 850, 1900,2100 MHz
CDMA 2000(800MHZ/1900MHZ)
Lưu ý:
1. Most CDMA -2000 operators don't offer Answer signal.
So VoIP to Mobile, DMT-E1 will connect soon.
CDMA -2000 operators will start billing soon. It doesn't wait mobile side answer
2. CDMA Version doesn't support SMS Feature and 180/183 unavailable
3. CDMA version doesn't have Remote SIM feature
4. CDMA version doesn't support DTMF
Chức năng:
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 or SCBox 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.
VoIP Application: VoIP Gateway's E1/T1 port connects DMT's E1/T1 port.

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