1. Ensure the cabinet to accommodate MTG1000 is well-ventilated and strong enough to bear the
weight of MTG1000. It’s required that the width of the cabinet should be 482.6mm (19 inches);
2. Please wear anti-static wrist strap when installing MTG1000;
3. Power supply of MTG1000 should be 100 ~240V AC, and its socket is a three-pin socket which
should be grounded well;
4. To guarantee MTG1000 works normally and to lengthen the service life of the device, the humidity
and temperature of the equipment room where MTG1000 is installed should be maintained at an
appropriate scope.
5. Please keep MTG1000 away from high-powered transmitter, radar transmitting station and large-
current devices which may interfere to the running of MTG1000.

Wire Sequence of RJ48 (E1/T1) Cable
6
The E1/T1 ports of MTG1000 trunk gateway are connected with RJ48 cables. A RJ48 cable has two
PINs, and the wire sequence of each PIN is shown as follows:
1 2 3 4 56 7 8
PIN 1
1 2 3 4 56 7 8
PIN 2
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.
Modify PC’s IP Address
7
On the PC, add an IP address of 192.168.1.XXX, to make the PC at the same network segment with
MTG1000, since the default IP address of FE0 of the trunk gateway is 192.168.1.111.
(1) On the PC, click “Network Properties”. (2) Double-click “Internet Protocol (TCP/IPv4)”.

(3) Enter an available IP address which is at the same network segment with “192.168.1.111”.
Open a web browser and enter the IP address of MTG1000 (the default IP of FE0is 192.168.1.111,
while the default IP of FE1is 192.168.11.1 ). Then the login GUI will be displayed. Both the default
username and password are admin.
Log into MTG1000
8
Modify IPAddress of FE1
9
After logging into MTG1000, user needs to modify the IP address of FE1 which is the network port for
services.
If user has a public static IP address, please configure the IP address of FE1 into this public static IP
address; If SIP server is connected to a private network, FE1 should be at the same network segment
with the SIP server. After that, please restart the gateway for the configurations to take effect.
FE0is only used for local management or maintenance, while FE1is used for voice and signaling
interacting.
Configure PRI or SS7 Trunk
10
On the PRI Config PRI Trunk interface, add a PRI trunk. ‘Channel ID’ of the PRI trunk should be
the same with that of the peer switch.
As for the ‘Switch Side’ parameter, if the peer switch is configured as ‘User Side’, the PRI trunk
should be configured as ‘Network Side’;if the peer switch is configured as ‘Network Side’, the PRI
trunk should be configured as ‘User Side’.
(1) Configure PRI Trunk

(2) Configure SS7 Trunk
1. On the SS7 Config SS7 Trunk interface, add an SS7 trunk. Please consult local service provider
about the information of Protocol Type (TUP/ISUP) , OPC and DPC.
2. On the SS7 Config SS7 MTP Link interface, add an SS7 signaling link for the trunk. Please
consult local service provider about the information of E1/T1 Port No. and Channel No. of the SS7
signaling link, as well as caller type.

3. On the SS7 Config SS7 CIC interface, add an SS7 circuit for the SS7 trunk. Generally, an E1 port
contains 32 channels, while a T1 port has 24 channels. Please consult local service provider about the
information of CIC.
Configure E1/T1 Frame Mode
11
2. On the PSTN Group Config E1/T1 Parameter interface, modify the frame mode of E1/T1 port to
make it the same with that of the peer device.

Configure SIP Trunk
12
On the SIP Config SIP Trunk interface, add a SIP trunk. User needs to fill in the IP address of the
peer device (remote address) and remote port. Other parameters can be retained as default settings .
Configure Outbound and Inbound Routes
13
(1) Configure Outbound Route
On the Call Routing IP >PSTN Routing interface, add an outbound route. Select a source type and
a destination type. If ‘.’is filled in for Caller Prefix and Callee Prefix, it means any number can be
caller number and callee number.

(2) Configure Inbound Route
On the Call Routing PSTN >IP Routing interface, add an inbound route. Select a source type and a
destination type. If ‘.’is filled in for Caller Prefix and Callee Prefix, it means any number can be caller
number and callee number.
This document only provides instructions for quick installation and basic configuration. For
detailed explanation of functions and parameters, please make reference to MTG1000 Trunk
Gateway User Manual, or ask for online technical support.
Detailed Configuration & Parameter Explanation
14

1) E1/T1 indicator is still dull after the corresponding E1/T1 port has been connected to an E1/T1 cable.
A. If the E1/T1 port is directly connected to a peer device with a standard RJ48C E1/T1 cable, please
check whether the peer device is equipped with standard RJ48C interface first, and then check whether
the wire sequence of E1/T1 cable is correct or nor.
B. If the E1/T1 port is connected to a switch with E1/T1 cable and coaxial line, please check whether
the connector of BNC transit box works well or not, and then check whether RX end and TX end are
connected properly.
C. Exchange the E1/T1 cable with that of another E1/T1 port that works normally, so as to confirm
whether the E1/T1 port malfunctions.
2）E1/T1 indicator flashes after the corresponding E1/T1 port has been connected to an E1/T1 cable .
A. E1/T1 indicator flashes intermittently
This phenomenon is caused by error code. Please log into the WEB interface to modify the frame mode
of the E1/T1 port. If the E1/T1 indicator still flashes slowly, it means there are error codes in the link.
Please contact service provider to check this problem.
B. E1/T1 indicator flashes fast
This phenomenon occurs as E1/T1 physical link is blocked. In this case, the trunk gateway cannot
receive any data from the peer device. Please contact service provider to check this problem.
3）Forget the IP address of MTG1000
Connect the trunk gateway’s console port to a PC via an RS232 console cable. After entering in the
command interface, input ‘show int’ under the ‘ROS#’ mode to query the current IP address of
MTG1000.
4）Forget username and password
Connect the trunk gateway’s console port to a PC via an RS232 console cable, and then ask for online
technical support.
