DGW100 SIP-ISDN Gateway Series UserManual
www.redstonesystems.com2-11
2.2 Requirements of installation
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).
Long term high humidity may lead to bad insulation and even cause electricity leakage, and it may
cause metal corrosion,too.
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℃.
High temperature acceralets aging of electrical parts and insulation materials.
Low temperature, however, may destabilize the operation of gateway.
2.2.2 Cleanliness and Ventilation
Dust is very harmful to the safe operation of the gateway. Dust that is adsorbed by static electricity acts as
insulator may cause poor contact between metal components and contacts, 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.
In addition, keep at least 5cm clearance at the air intake and air exhaust vent of the gateway to ensure
perfect ventilation for heat dissipation. The rack for DGW100also must with good ventilation system.
2.2.3 Power Supplier
Check whether the voltage of the power supply system is stable or not, and whether the power rate can
meet with the requirement or not.
The speficiation of DGW100power supply:100V~240V(AC),50~60Hz,1A,or -36V~-72V(DC),2.5A.
2.2.4 Grounding
For AC power supply system
When the installation site without independent grounding system, the AC power supply system must
ensure:
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.
In an installationequipment room that can provideindepedent grounding, the specialized ground
terminalwhich provided by DGW100shall be connected reliably with the independent grounding system
in the equipment room. And this can not only ensure the safety of equipment during operation, but also
can avoid the voice quality being disturbed by the environment.
For DC power supply system
The DC power working ground (the positive pole of the -48V DC power supply or negative pole of the
24V DC power supply) of the communications site should be connected with the indoor collective

DGW100 SIP-ISDN Gateway SeriesUser Manual
Redstone Systems, Inc.
grounding cables nearby, and the grounding cables should meet the requirement for the maximum load of
the equipment.
The power supply equipment of the communications site should be connected with from the collective
ground cable in the communications building (or from the protection grounding bar of the equipment) to
the DC working ground cable.
2.2.5 Electromagnetic Environment
Any possible interference source, wherever it is from, impacts the gateway negatively. In order to
improve the ability of resist the interference and lightning protection of the gateway, make sure that:
Keeping the gateway far from high power wireless radio station, radar station, and high-frequency
large current devices.
The gateway is capable for 2nd class of lightning protection on wires and cables, if there is outdoor
wire,then it must adopts1st class of 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
DGW100requires an installation site withgood air-flow system 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
Be sure to subscribe PSTN lines from local telephone company and activate the lines prior to the

3.3 Connecting Cables
3.3.1 Connecting Console (CON) Port Cables
A CON should be provided by DGW100to 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.
RJ45 Plug is used to connect with the CON cable to connect with one of the CON port of the
gateway,andanother port is applied for DB9 Adapter to insert serial ports of configuration terminal. CON
Ratio: 115200.
Console Port cable installation procedure is as following:
Step1 Choose a terminal (PC).
Step2 Power off the terminal and connect RS232 port with the Console port(CON) of the gateway by
the Console port cable.

3.3.2 Connecting the Ethernet Cable
The DGW100has 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 DGW100has two service interfaces, namely ETH1 and ETH2. 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 steady green or
blinking green, it indicates that the connection is established properly.
The DGW100has two auxiliary interfaces, namely AUX1 and AUX2. In most cases, no connection is
required.
3.3.3 Connecting the T1/E1 Cable
T1/E1 terminal of DGW100provides ISDN port for connection with PBX or PSTN.

DGW100 SIP-ISDN Gateway SeriesUser Manual
