Digital Mobile Trunk
One set 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 fist 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 gty of GSM modules is 31 ports.
