1Product Description
1.1 Overview
MTG3000 is a new-generation intelligent VoIP trunk gateway, featuring high integration
and large-capacity concurrency. Focusing on a concept of maintainable, manageable and
operable, it provides carrier-grade VoIP, FoIP and Modem/POS services, as well as value-
added functions such as smart voice recognition, signal encryption and flexible dialing rules.
It supports supports the conversion of multiple coding methods such as G.711A/U, G.723.1,
G.729A/B, iLBC and AMR. It has good compatibility with Huawei SoftX3000, and other
softswitches and IMS systems from ZTE, Cisco, and VOS.
Compared with similar gateways, MTG3000 trunk gateway has more advantages in terms
of performance, system reliability and interoperability. Its high-efficient design and strong
DSP processor ensure the interconversion of PCM voice signal and IP packets, although
the gateway has been fully loaded. It can be connected with multiple devices such as
softswitch, PBX and those servers equipped with digital trunk boards.

2Quick Installation
2.1 Preparations before Installation
2.1.1 Attentions for Installation
The attentions for installing MTG3000 include:
⚫To guarantee MTG3000 works normally and to lengthen the service life of the
device, the humidity of the equipment room where MTG3000 is installed should
be maintained at 10%-90% (non-condensing), and temperature should be 0 ℃ ~
45 ℃;
⚫Ensure the equipment room is well-ventilated and clean;
⚫Power supply of MTG3000 should be 100 ~ 240V AC, and its socket is a three-
pin socket which should be grounded well;
⚫It's suggested that personnel who has experience or who has received related
training be responsible for installing and maintaining MTG3000;
⚫Please wear anti-static wrist strap when installing MTG3000;
⚫It's advised to adopt uninterruptible power supply.
2.1.2 Preparations about Installation Site
⚫Equipment Cabinet
Ensure the cabinet is well-ventilated and strong enough to bear the weight of
MTG3000. It's required that the width of the shelf should be 19 inches.
⚫Trunk
Ensure telecom operator has approved to open a trunk.
⚫IP Network
Ensure Ethernet PBX or router under IP network has been prepared, since
MTG3000 is connected to the IP network through the standard 10/100/1000M
Ethernet port.
⚫Socket
Ensure the socket of MTG3000 is a three-pin socket, and power supply is
grounded well.
2.1.3 Installation Tools
⚫Screwdriver

MTG3000 Trunk Gateway User Manual | Dinstar
9
⚫Anti-static wrist strap
⚫Ethernet cables, power wires, telephone wires
⚫Hub, telephone set, fax, and PBX
⚫Terminal (can be a PC which is equipped with hyper terminal simulation software)
2.2 Installation of MTG3000
2.2.1 Put MTG3000 into Shelf
1. Use screws to fix a flank on the left and the right of MTG3000 respectively;
2. Put the MTG3000 device into the shelf horizontally;
3. Fix the flanks of MTG3000 on the cabinet by using screws.
2.2.2 Connect Grounding wire to MTG3000
Connect one end of the Grounding wire to the grounding lug on the back of MTG3000 and
then connect the other end to the grounding bar of the shelf.
2.2.3 Connect MTG3000 to Ethernet
MTG3000 has two network ports, namely the gigabit Ethernet port for services (GE1) and
the gigabit Ethernet port for network management (GE0). It is advised to connect GE1 to
the IP network.
Both GE1 and GE0 can be used to carry out management on MTG3000, but only GE1 is
put in use generally. GE0 is used when there is a need to separate the management on
MTG3000 from the service processing of the MTG3000. As shown below：
2.2.4 Connect MTG3000 to PSTN
Generally, a distribution frame needs to be used for the connection between MTG3000 and
PSTN. Firstly, connect one end of E1 cable to one of the E1/T1 ports of MTG3000, and
then connect other end to the E1 port of the distribution frame. Second, connect one end of
the cable to the distribution frame, and then connect the other end to the exchanger or PBX
under the PSTN.

2.3 Cabling of E1/T1 Port
If there is a need to deploy multiple cables, it had better to make a mark on each cable and
write down IP address and destination port in order to simplify the follow-up connection,
debugging and maintenance.
2.3.1 How to make RJ-48 joint for E1/T1 Cable
1. Prepare a twisted-pair cable with a length of at least 0.6 meters, and then remove the shuck
of the cable as follows:
2. Sequence the lines of the cable according to the following figure.
PIN1: orange & white, orange, green & white, blue, blue & white, green, brown &
white, brown.
PIN2: blue, blue & white, green & white, orange & white, orange, green, brown &
white, brown.
3. Put the lines into two pins of RJ-48 joint according to the mentioned sequence of the lines.
4. Use a RJ-48 wire crimper to crimp the RJ-48 joint.

Note：
Generally, a RJ-48 cable will be provided together with the MTG3000 device,
and users have no need to make RJ-48 joints by themselves.
2.4 Troubleshooting
When the MTG has been connected to the optical transceiver, but light 0 on the SDH board
is still dull or it flashes, please check according to the following steps.
a. Check whether the MTG3000 gateway is properly connected to the optical fiber.
b. Switch the Tx port with the Rx port of MTG3000
c. Check whether the numbers of the two ends of the optical fiber are the same.
d. Carry out a loopback test.
MTG3000 provides three methods for loopback test:
1. Loopback within a single DTU board: loopback between the front 8 virtual E1/T1
ports and back 8 virtual E1/T1 ports.
2. Loopback between DTU boards: loopback between DTU0 and DTU1; loopback
between DTU1 and DTU3.
3. User-defined loopback: loopback based on actual needs. (As for this loopback test,
