Installation Instructions

• Cabinet requirement: ensure the cabinet to accommodate MTG1000/MTG2000/MTG2000(B) is well-ventilated and strong enough to bear the weight of the device. It’s required that the width of the cabinet be 482.6mm (19 inches);
• ESD protection: please wear anti-static wrist strap when installing MTG1000/ MTG2000(B);
• Power supply: MTG200 accepts DC 12V power input, while other MTG models accept AC voltage of 100- 240 V. It’s recommended that users use UPS (uninterruptible power system).
• Device grounding: please ensure the gateway is properly grounded. To avoid interference with power source, it’s recommended that the earth resistance be less than 2Ω;
• Temperature and humidity: to avoid any accident that might cause malfunction, it’s advised to install the gateway in an equipment room where temperature and humidity are appropriate; the equipment room should be clean and ventilated enough to facilitate heat dissipation;
• Anti-jamming: to reduce interference, please keep MTG devices away from high-powered transmitter, radar transmitting station and large-current devices .

Modify PC’s IP Address

To log in the Web Management System of the trunk gateway, you need to modify the IP address of PC first to make it at the same network segment with the gateway. Connect PC with the gateway, and then add an IP of 192.168.1.XXX or 192.168.11.XXX on the PC.

1. On the PC, click ‘Network (or Ethernet)→Properties’.

2. Double-click ‘Internet Protocol Version 4 (TCP/IPv4)’.
   

3. Select ‘Use the following IP address’, and then enter an available IP address ‘192.168.11.XXX’ or ‘192.168.1.XXX’ .
   

Log in Web Management System

Open a web browser and enter the IP address of the trunk gateway, and then input the IP address of GE0 or Ge1 which is connected to the PC. Press Enter, and the login GUI will be displayed.

Enter username and password in the displayed login GUI. The default username is admin and default password is ad min@123#.
Note: PC and the connected network port must be at the same network segment.

Modify IP Address of Network Port for Services

After logging in the trunk gateway, user needs to modify the IP address of the network port for services. If there’s a public static IP address, please configure the IP address of the network port into this static IP address. If SIP server is connected to a private network, the network port for services should be at the same network segment with the SIP server. After that, please restart the gateway for the configurations to take effect.
The network port for management is only used for local management, while the network port for services is used for voice and signaling interacting.

Configure PRI/SS7 Trunk

1. Configure PRI Trunk
   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’.
   

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 ‘E1/T1 Port No.’, ‘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 ‘Start CIC No.’.
   

Configure E1/T1 Frame Mode

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

1. On the SIP Config →SIP Trunk interface, 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 & Inbound Routes

1. Configure Outbound Route
   On the Call Routing → IP >PSTN Routing interface, add an outbound route. Select a source trunk and a destination trunk that have been created. If ‘.’ is filled in for Caller Prefix and Callee Prefix, it means any number can be the caller number and callee number of this outbound route.
   

2. Configure Inbound Route
   On the Call Routing → PSTN >IP Routing interface, add an inbound route. Select a source trunk and a destination trunk that have been created. If ‘.’ is filled in for Caller Prefix and Callee Prefix, it means any number can be the caller number and callee number of this inbound route.

Trouble Shooting

1. What if E1/T1 indicator is still dull after the corresponding E1/T1 port has been connected to an E1/T1 cable?
   A. In case that 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 not.
   B. In case that 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 the RX end and TX end are connected properly.
   C. Exchange the E1/T1 cable with another one that works normally, so as to confirm whether the E1/T1 port malfunctions.

2. What if E1/T1 indicator flashes after the corresponding E1/T1 port has been connected to an E1/T1 cable?
   Log into the web management system to modify the frame mode of the E1/T1 port. If the E1/T1 indicator still flashes, it means there are error codes in the physical link. Please contact service provider to check this problem.

3. Forget the IP address of the trunk gateway.
   Connect the trunk gateway’s console port to a PC via an RS232 serial cable. After the command interface is displayed, input ‘show int’ under the ‘ROS#’ mode to query the current IP address of the gateway.

4. Forget username and password.
   Connect the trunk gateway’s console port to a PC via an RS232 serial cable, and then ask for online technical support.
