DMT-V: 30 ports VoIP GSM Gateway (support SIP and H.323)

~with CDR,LCR,Remote Monitor
~GSM ,CDMA can be combined in one DMT-V

Frequecny:
Quad Band:900/1800/1900/850MHZ
3G/UMTS: for all world and Japan (SoftBank ,Docomo)
3G:EDGE/GPRS 850, 900, 1800, 1900 MHz / HSDPA/UMTS 850, 1900, 2100 MHz
CDMA 2000(800/1900MHZ)

<<Functions>> 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. 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: Gateway's E1/T1 port connects DMT's E1/T1 port.     *Optional external SCE-900,adapts 992 SIM cards.(Expands SIM card upto 32 pieces per GSM channel. )   SCE-900 connects DMT via RS-232. The application software heaps the calling time of per SIM card. If it need to change SIM card, DMT will command SCE to change. Dimensions: 19” standard cabinet. Height 2U. Depth 26 cm.       *Optional external SCBox,adapts124 SIM cards.(Expands SIM card upto 4 pieces per GSM channel.)
<<System architecture>>
One set of DMT connects one ISDN E1/PRI. MCU decodes the signal and receives the called number code. MCU sends the called number code to MTIC. MTIC send out GSM voice channel and connect with E1 PRI voice channel.DMT is designed on the principle of “One to One” connection. The first channel of E1 / PRI will connect with the first MTIC GSM Module。One MTIC includes 4 ports. (One PCB module provides 4 ports of GSM Module). The last 1 ports on the last MTIC are idle. Therefore, total qty of GSM modules is 31 ports.
<<Mechanism>>
DMT dimensions: 19” standard cabinet; Height 5U, Depth 42cm. 1U in the top of DMT is MCU, The lower 4Uconsists of these PCB modules: 8 x MTIC, 1x E1 Trunk, Ctrl, IMS and Power MTIC: 4 LED on the front plate indicates status of each port. 4 outlets are for 4 antennas.
GSM spec in the MTIC：   MTIC (1) Providing 4 port GSM. (2) LED GSM status display.   GSM Frequency : Dual Band EGSM 900 and GSM 1800(GSM Phase 2+) (1) GSM Frequency bands:Dual Band EGSM 900 and GSM 1800(GSM Phase 2+) (2) GSM class:Small MS (3) Transmit power:Class 4(2W) for EGSM 900 (4) Class 1(1W) for GSM 1800 (5) SIM card reader :External - connected via interface connector (6) Antenna:50 Ohm antenna coaxial connector (7) Temperature range :Normal operation: -20℃ to +55℃ (8) Restricted operation: -25℃ to -20℃ and +55℃ to 70℃ (9) Storage:-40℃ to +85℃   E1/T1 Trunk(ISDN E1/T1 PRI)         CONTROL CARD   (1) Providing Digital Tone Source required in the RACK. (2) ±15dB Gain Adjustment。   IMS：512*512 Digital Switch   Power   (1) Input Voltage：AC90-135V，AC180-264V，50Hz~60Hz。 (2) Input Current：8A for 115VAC，5A for 230VAC (3) Type：Switching。 (4) Output：+3.3V_28A，+5V_30A，+12V_15A，-5V_0.5A，-12V_1A，+5VSB_2A。 (5) Total Power：300W
Antenna collecting Box: Base equipment.
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. More detail..
