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;
Please do not hot plug or unplug cables;
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.
Trunk
Ensure telecom operator has approved to open a trunk.
IP Network
Ensure router under IP network has been prepared, since MTG3000 is connected to the IP network
through the standard 10/100/1000M Ethernet port.
Power Supply
Ensure the socket of MTG3000 is a three-pin socket and power supply is grounded well.
2.1.3 Installation Tools
Screwdriver
ESD wrist strap
Ethernet cables, power wires, telephone wires
Hub, telephone set, fax, and PBX
Terminal (can be a PC which is equipped with hyperterminal simulation software)

2.1.4 Unpacking
Open the packing container to check whether the MTG3000 device and all accessories have been in it:
One MTG3000 device
1.8-meter-long of power wire (AC 250V/4A)
Optical fiber
One network cable
One grounding wire
Serial console cable
Mounting ears and screws
2.2 Installation of MTG3000
2.2.1 Put MTG3000 into Shelf
1. Use screws to fix a mounting ear on the left and the right of MTG3000 respectively;
2. Put the MTG3000 device into the shelf horizontally;
3. Fix the mounting ears s of MTG3000 on the cabinet by using screws.
2.2.2 Connect Ground Wire to MTG3000
Connect one end of the ground wire to the grounding port on the back of MTG3000 and then connect the
other end to the grounding bar of the shelf.
2.2.3 Connect MTG3000 to Network
MTG3000 has two network ports, namely the gigabit network port for services (GE1) and the gigabit
network 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.

2.2.4 Connect MTG3000 to PSTN
Use an optical fiber to connect MTG3000 and an optical transceiver which is under the PSTN network. The
optical fiber includes the Tx wire and the Rx wire. The Tx port of MTG3000 is connected to the Tx port of
the optical transceiver, while the Rx port of MTG3000 is connected to the Rx port of the optical transceiver.

2.3 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, user needs to set
mapping relationship on the SDH Config Channel Map interface on Web).

3Basic Operation
3.1 Configuration of IPAddress
The default IP address of GE1 is 192.168.1.111, while that of GE0 is 192.168.11.1.When GE1 is in use, it’s
required that the IP address of GE1 and the IP address of PC are at the same network segment.
1. Connect the GE1 port of MTG3000 to a PC by using a network cable.
2. On the PC, open the TCP/IP Settings interface, click Advanced, and then click Add to add an IP
whose format is 192.168.1.XXX. Or you can open the Internet Protocol (TCP/IP) interface to modify an
existing IP into 192.168.1.XXX.
3.2 Local Maintenance
To ensure easy maintenance, the MTG3000 trunk gateway provides a standard RJ48 console port, which
has a Baud rate of 115200bps. Users can log in the MTG3000 to carry out maintenance-related
configurations through the console port.

Copyright @ 2011-2016 Dinstar
3.2.1 Example: Log in MTG3000 via Console Port
Step 1: Prepare a serial cable.
Step 2: Connect the F port of the serial cable to the COM port of PC.
If the PC does not have a COM port, please use a USB-to-COM converting tool to connect the serial cable
to the PC.
Step 3: Connect the M port of the serial cable to the console port of MTG3000.
Step 4: Conduct configurations on login software.
Herein we take the PuTTY sofeware as an example. Detailed configurations are as follows:
(COM1 is an example. Please enter correct serial line according to actual conditions.)
