1 Overview
1.1 Product Introduction
The TGWxE1 Trunking Gateway (hereinafter referred to as the TGWxE1) is one of VoIP product series
developed by Tadiran Telecom.It uses the SIP and T1/E1 interfaces for the inter-conversion of IP packets
and PCM signals, allowing the interworking of the IP-based new-generation voice network to legacy
Public Switched Telephone Network (PSTN), and the private branch exchange (PBX) of an enterprise.
As a carrier-class VoIP gateway, the TGWXE1 is designed under the requirements of telecom operators,
integrators, value-added service providers as well as large and medium-sized enterprises for VoIP
services. The TGWXE1 has distinctive advantages over other similar products in terms of performance,
system reliability, compatibility and cost performance. In addition, the TGWXE1 has efficient
software/hardware architecture and powerful DSP processing capabilities, ensuring the realization of
major functions (including the conversion between PCM signals and IP packets, G.711 or G.729A
encoding and decoding of voice signal, and echo cancellation, etc.) even under full load conditions.
By supporting the ISDN PRI signalling, the TGWXE1 can control its calls with the PSTN or PBX. The
call control between the TGWXE1 and media gateway controller (softswitch) is carried out through
Session Initiation Protocol (SIP). By now, the TGWXE1 has successfully passed the interoperability test
with various popular softswitch platforms and IP PBX products.
1.2 Features

2 Installation Preparation
For avoidance of personal injury and device damage, please read this chapter carefully before installation.
2.1 Installation Precautions
For your safety, please follow the precautions when TGWXE1 is installed and used.
Keep the site far from the heat and humidity
Take precautions with use of high-voltage electricity
Please let the experienced or trained operator to install and maintain TGWXE1
Wear static discharge wrist strap
Ensure the proper electric ground of installed equipment
Properly connect the power cable to TGWXE1
Do not plug the power cable when in use
UPS is advised
2.2 Site Requirements
2.2.1 Temperature and Humidity
Check the temperature and humidity of equipment room. To ensure the normal operation and long service
life of the gateway, the temperature and humidity in the room should be kept at the proper range.
The humidity in the equipment room should be kept between 10% and 90% (non-condensing). Abnormal
humidity condition may cause problems to the gateway:
Long term high humidity may lead to bad insulation and even cause electricity leakage, mechanical
property change and corrosion.
Low humidity is likely to leave captive screws to loose due to static electricity built up and the
insulation washer shrunk.
The temperature in the equipment room should be kept between 0℃and 40℃. Abnormal temperature
condition may cause problems to the gateway:
High temperature acceralets aging of electrical parts and insulation materials.
Low temperature, however, may destabilize the operation of gateway.

TGWxE1 Gateway Series UserManual
Tadiran Technologies, Inc. 2-7
2.2.2 Cleanliness
Dust is very harmful to the safe operation of the gateway. Dust that is adsorbed by static electricity acts as
insulator, which not only affects the service life of the gateway but also leads to communication failure.
Therefore, the room for the gateway must be kept clean.
To ensure adequate ventilation to keep the gateway from overheating, there should be adequate clearance
for the air intake and the air exhaust vents. Keep at least 6 cm clearance at the left and right side of the
chassis where the air intake is and at least 15 cm clearance at the rear of the chassis where the exhaust
vents located.
The rack for TGWXE1 should have a good ventilation system.
2.2.3 Power Supplier
Check the power supply system against the electrical specification of the gateway.
2.2.4 Grounding
To maintain good voice quality, proper grounding of the AC supply is critical to minimize the noise from
the AC interference. Therefore, the following conditions must be ensured:
The AC power outlet has a protection ground contact.
The ground contact of AC supplier must be grounded properly.
Avoid sharing the multi-outlet power strip with other devices that may generate electrical interference.
TGWXE1 is chassis based with ground tab.
In a site that can provide ground for the chassis, the ground tab at the rear panel of chassis for TGWXE1
must be properly grounded.
2.2.5 Electromagnetic Environment
Any possible interference source, wherever it is from, impacts the gateway negatively. To resist the
interference, make sure that:
Keeping the gateway far from radio transimitting station, radar station, and high-frequency devices.
Use electromagnetic shielding when necessary.
The gateway is capable for secondary lighten protection on wires and cables that connected to outside
buildings.The site must provide the primary lighten protection.
The power supply system should be used independently as much as possible and effective measures of
preventing electric grid from interference should be adopted.
Ensure a good power grounding effect of equipment or add a lightning protector.
2.2.6 Other Facilities
Rack/Workbench
TGWXE1 is designed to be installed in a standard 19-inch rack, which should provide adequate
air-flow to cool down the gateway, and should be firm enough to support the weight of the gateway. It
is also recommended the rack is earth grounded properly.
PSTN Line
If the gateway is equipped with T1/E1 interface, be sure to subscribe PSTN lines from local telephone
company and activate the lines prior to the installation.
IP Network

TGWxE1 Gateway Series UserManual

3.3 Installing Cables
3.3.1 Connecting Console Port
A CON should be provided by TGWXE1 to check errors of the device. Connect the CON with
computer’s RS232 serial ports, then local computers can interwork with the device through simulating
terminal program.
As to TGWXE1, RJ45 Plug is used. One port is applied for connecting CON, while the other is applied
for DB9 Adapter to insert serial ports of configuration terminal. CON Ratio: 115200.
Console Port cable installation procedure is as followed:
Step1 Choose a terminal (PC).
Step2 Power off the terminal and connect RS232 port with the Console port.

3.3.2 Connecting the Ethernet Cable
The TGWXE1 has the dual-network-interface redundancy function. When one of the network interfaces
is disconnected or does not work well, traffic services can be switched seamlessly to the other one.
The TGWXE1 has two service interfaces, namely ETH1 and ETH2 for your choice. These two interfaces
need to be connected to the same hub, LAN, or WAN. Only one of them works at a time. After Ethernet
cables are inserted, check the indicator state of the interface that is connected first. If the indicator is long
green or blinking green, it indicates that the connection is established properly.
The TGWXE1 has two auxiliary interfaces, namely AUX1 and AUX2. In most cases, no connection is
required for auxiliary interfaces.
3.3.3 Connecting the T1/E1 Cable
TGWXE1 offers RJ45 jack as T1/E1 connector for making ISDN connection with PBX or PSTN.
Please identify the connector type and interface impedance of the other side equipment before making
T1/E1 connection.
If the other side equipment offers same RJ45 jack, use CAT5 cable with RJ45 plugs on both side to make
T1/E1 cable connection. Be sure to mach TX and PX pair according to the PIN specification when
making the CAT5 cable.
If the other side equipment offers separate TX/RX coax connectors for T1/E1connection, use
RJ45-Balum-Coax cable sets and follow the figure to make the connection.
