E1/T1/VoIP
GSM/CDMA Gateway
E1/T1/VoIP GSM/CDMA Channel Bank
~E1*1(or VoIP) , GSM*31 (two ways)
Digital
Mobile Trunk (DMT)
accepts incoming call from E1/T1 PRI of PSTN or PBX
and choose one GSM channel to dial out according to
the prefix of the destination mobile number. In this
way, we can have least cost routing. DMT can provide
Call Detail Record (CDR) for traffic and accounting
management.
*Besides PRI to GSM,you maybe also apply GSM to PRI
(two ways).
GSM
Frequecny:
Dual BAND:900/1800 MHZ
Tri Band: 900/1800/1900MHZ
Tri Band: 850/1800/1900MHZ
Quad Band:900/1800/1900/850MHZ
CDMA
2000(800MHZ)

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¡COne 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. |

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. |

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.
