E1/T1 GSM Gateway / E1/T1 GSM Channel Bank
~Application 1: E1*2 in , GSM*31 out
When you do call terminal, DMT-2 can accept incoming call from 2 E1/T1 PRI and choose one GSM channel to dial out according to the prefix of the destination mobile number
~Application 2: E1*1 in, GSM*31 and E1*1 out.
DMT-2 is connected between PSTN and PBX using the E1/PRI interface. It routes the mobile calls from PBX through mobile channels instead of going directly to the PSTN, hence reduces higher rate charge for fix to mobile calls. If the call is not a mobile call, it just goes directly to the PSTN. On the other side, the calls come from PSTN will be passed to the PBX. Thus the DMT-2 can perform the LCR(Least Cost Route) function. (More detail as follows)

 Catalog (502KB ) | | | | System Application | | Application 1 |  | | | | Application 2 | .gif) | | | | Mechanism |  | | | | |  | | The DMT-2 contains 2 E1/PRI interfaces and 31 mobile channels. One E1/PRI connects to PSTN while the other E1/PRI connects to PBX. The MCU of DMT-2 decodes the signal and retrieve the called number to determine whether this call should go through mobile channel or E1/PRI channel. There are 8 MTIC cards, and each MTIC card contains 4 mobile channels. The last port on the last MTIC card is spared for system use. Therefore, total number of mobile channels is 31 ports. | | | | | DMT-2 dimensions: 19" standard cabinet; Height 5U, Depth 42cm. 1U in the bottom of DMT-2 is MCU, The upper 4U consists of these PCB modules: 8 x MTIC,2 x E1 Trunk, 3 x 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 ports GSM. | | (2) LED GSM status display. |
