4 Installation Instructions

Cabinet Requirement: Ensure the cabinet is well-ventilated and strong enough to bear the device's weight. The required cabinet width is 482.6mm (19 inches).

ESD Protection: Wear an anti-static wrist strap when installing MTG1000/MTG2000(B).

Power Supply: MTG200 accepts DC 12V. Other MTG models accept AC voltage of 100-240V. Using a UPS (uninterruptible power system) is recommended.

Device Grounding: Ensure the gateway is properly grounded. Earth resistance should be less than 2Ω to avoid interference.

Temperature and Humidity: Install the gateway in an equipment room with appropriate temperature and humidity. The room should be clean and ventilated for heat dissipation.

Anti-jamming: Keep MTG devices away from high-powered transmitters, radar stations, and large-current devices to reduce interference.

6 Wire Sequence of RJ48(E1/T1) Cable

The E1/T1 ports of MTG trunk gateways are connected with RJ48 cables. An RJ48 cable has two PINs, and the wire sequence of each PIN is shown below:

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.

7 Modify PC's IP Address

To log in the Web Management System of the trunk gateway, you need to modify the IP address of the PC first to make it at the same network segment with the gateway. Connect the PC with the gateway, and then set an IP address 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 (e.g., '192.168.11.XXX' or '192.168.1.XXX') and Subnet mask (e.g., 255.255.255.0).

8 Log in Web Management System

Open a web browser and enter the IP address of the trunk gateway. 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 admin@123#.

Note: PC and the connected network port must be at the same network segment.

9 Modify IP Address of Network Port for Services

After logging into the trunk gateway, modify the IP address of the network port for services. If a public static IP address is available, configure it here. If the SIP server is on a private network, the network port for services should be on the same network segment as the SIP server. Restart the gateway for changes to take effect.

The network port for management is for local management, while the network port for services is for voice and signaling interaction.

10 Configure PRI/SS7 Trunk

Configure PRI Trunk

On the PRI Config → PRI Trunk interface, add a PRI trunk. The 'Channel ID' of the PRI trunk should match the peer switch. If the peer switch is configured as 'User Side', configure the PRI trunk as 'Network Side', and vice versa.

Configure SS7 Trunk

SS7 Trunk Configuration: On the SS7 Config → SS7 Trunk interface, add an SS7 trunk. Consult your service provider for Protocol Type (TUP/ISUP), OPC, and DPC information.

SS7 MTP Link Configuration: On the SS7 Config → SS7 MTP Link interface, add an SS7 signaling link. Consult your service provider for 'E1/T1 Port No.', 'Channel No.', and 'Caller Type'.

SS7 Circuit Configuration: On the SS7 Config → SS7 CIC interface, add an SS7 circuit. An E1 port typically has 32 channels, and a T1 port has 24 channels. Consult your service provider for the 'Start CIC No.'.

11 Configure E1/T1 Frame Mode

On the PSTN Group Config → E1/T1 Parameter interface, modify the frame mode of the E1/T1 port to match that of the peer device.

12 Configure SIP Trunk

On the SIP Config → SIP Trunk interface, enter the IP address of the peer device (remote address) and the remote port. Other parameters can be retained as default settings.

15 Trouble Shooting

Issue: E1/T1 indicator is still dull after connection.

• Scenario A (Direct Connection): Check if the peer device has a standard RJ48C interface and if the E1/T1 cable wire sequence is correct.
• Scenario B (Connection via Switch): Check if the BNC transit box connector works and if the RX and TX ends are connected properly.
• Scenario C (Cable Fault): Exchange the E1/T1 cable with a known working one to test the port.

Issue: E1/T1 indicator flashes after connection.

Log into the web management system to modify the E1/T1 port's frame mode. If the indicator continues to flash, it indicates physical link error codes. Contact service provider for assistance.

Issue: Forgotten IP address of the trunk gateway.

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

Issue: Forgotten username and password.

Connect the gateway's console port to a PC via an RS232 serial cable and contact online technical support.
