2Quick Installation
2.1 Preparations before Installation
2.1.1 Attentions for Installation
The attentions for installing MTG2000B include:
⚫To guarantee MTG2000B works normally and to lengthen the service life of the
device, the humidity of the equipment room where MTG2000B 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 MTG2000B 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 MTG2000B;
⚫Please wear anti-static wrist strap when installing MTG2000B;
⚫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
MTG2000B. 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
MTG2000B is connected to the IP network through the standard 10/100/1000M
Ethernet port.
⚫Socket
Ensure the socket of MTG2000B is a three-pin socket, and power supply is
grounded well.

MTG2000B Trunk Gateway User Manual | Dinstar

2.1.3 Installation Tools
⚫Screwdriver
⚫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 MTG2000B
2.2.1 Put MTG2000B into Shelf
1. Use screws to fix a flank on the left and the right of MTG2000B respectively;
2. Put the MTG2000B device into the shelf horizontally;
3. Fix the flanks of MTG2000B on the cabinet by using screws.
2.2.2 Connect Grounding wire to MTG2000B
Connect one end of the Grounding wire to the grounding lug on the back of MTG2000B
and then connect the other end to the grounding bar of the shelf.
2.2.3 Connect MTG2000B to Ethernet
MTG2000B 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 MTG2000B, but only GE1 is
put in use generally. GE0 is used when there is a need to separate the management on
MTG2000B from the service processing of the MTG2000B. As shown below：

MTG2000B Trunk Gateway User Manual | Dinstar

2.2.4 Connect MTG2000B to PSTN
Generally, a distribution frame needs to be used for the connection between MTG2000B
and PSTN. Firstly, connect one end of E1 cable to one of the E1/T1 ports of MTG2000B,
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.

MTG2000B Trunk Gateway User Manual | Dinstar

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 above 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 MTG2000B
device, and users have no need to make RJ-48 joints by themselves.

3Basic Operation
3.1 Configuration of IP Address
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 MTG2000B to a PC by using a network cable.
2. 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 MTG2000B trunk gateway provides a standard RJ45
console port, which has a Baud rate of 115200bps. Users can log in the MTG2000B to carry
out maintenance-related configurations through the console port.

MTG2000B Trunk Gateway User Manual | Dinstar
12
3.2.1 Example: Log in MTG2000B 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 line to
connect the serial cable to the PC.
Step 3: Connect the M port of the serial cable to the console port of MTG2000B
Step 4: Conduct configurations on login software.
Herein we take the PuTTY as an example. Detailed configurations are as follows
(COM1 is an example. Please enter correct serial line according to actual conditions.)
After finishing the above configuration, click the Open button to enter the following
interface.

Enter username and password, which are the same with the username and password of the
Web of MTG2000B. And then you will see a Linux platform where you can carry out
maintenance-related configurations.
Note：
For commands to query MTG2000B information, make reference
to Chapter 6.
3.3 Query IP
If you have changed the default IP address of GE1 or GE0 to a new IP address but forget it,
you can carry out the following procedures to query the IP address.
1. Use a serial line to connect the console port of MTG2000B with a PC;
2. Modify the baud rate to 115200;
3. Click OK, and then enter ‘ifconfig’, and the IP address of GE1 or GE0 of MTG2000B
will be displayed.
