Product Introduction
1.1 Product Introduction
Zed-3 GS8 is a Modular Gateway which has prefect performance, rich interfaces, and interface
cards plug capacity. GS8 supports GSM/CDMA, SIP, FXO interface, so it can be connected with
GSM/CDMA, VoIP and PSTN networks, allows calls to freely transfer between these interfaces.
GS8 permits flexible call routing and call restriction settings to provide users calling strategy
based on their own requirements. The web-based management platform dramatically reduces
complication of users' operations.
GS8 are compatible with most SIP-based IP-PBX and traditional telephony system. When there
is no PBX, it can be deployed alone or in a group. At the same time, this product can be connected
to local PSTN network directly since it supports most countries and areas' telephone protocols.
Zed-3 sales GS8 and provides technical supports over the world.

Chapter 2
Device Installation
Unpack the unit and verify shipment content with the packing list :
•One GS8 equipment.
•One power adapter and one power cable.
•One Ethernet cable.
•One copy of quick start guide.
•One copy of e-manual.
•One Zed-3 pen as a gift.
•Accessories package: six M6 screws, eight M4 screws, two GS8 fixers.
Note: If there is any missing or damage, contact the seller or Zed-3 sales immediately and save
all packages for the repackaging if need.
2.1 Installation Requirements
2.1.1 Power Requirements
•Power-off before installation, dismantlement or movement.
•The electric outlet shall be installed near the equitment and shall be easily accessible in case
of emergency.
2.1.2 Anti-static Requirements
•If the device's power line connects to external cable, take necessary anti-static actions please.
•Anti-static Requirements
- Static will damage the circuit or the whole machine seriously if static exceed the limitation,
so make sure the ground bus well enough.

2. Device Installation
8
- Static inside body will result in damage too, so please wear anti-static wristband if you
have.
2.1.3 Environment Requirements
2.1.3.1 Basic Conditions
Keep the GS8 equipment in a room which has proper control of temperature and humidity, watch
out the conductivity of the shelf. Too high or too low humidity will cause short circuit or fire. At the
same time, the conductive property of rack is also considerable.
Place the equipment on a rack (if possible) which is near stable and liable power in an anti-fire,
anti-humidity, anti-dust, and anti-thief room.
2.1.3.2 Temperature, Humidity, and Illumination
Suggestions:
•Temperature: 0 ~ 40
•Relative humidity: 5~ 95RH without coagulation
•Illumination: light, 500 ~750 lx, light enough for operations.
High humidity will affect the insulating efficiency of insulating materials and also cause the rust of
metals. Low humidity will make insulating gasket shrink, loose the fixed bolts, and scrape up
static. Long period of high temperature will accelerate components' aging, lower the reliability and
reduce the useful time dramatically.
2.1.3.3 Air Quality
The air particulate may enter the equipment through ventholes. Too much dust will cause
short-circuit, so the suggestion is less than 180mg/m3. In machinery room, printer and
Photocopiers shall be placed away from the power provider in case of floating particulate. Please
put it in the diagonal corner.
Keep the room clean, for the dust will cause static and bad connections between little
components
2.1.3.4 Ventilation Requirements
There are thermal discharge holes in the back and side side, so keep more than 100mm from
other stuffs for thermal discharging.
2.1.3.5 Safety
There must be some safety precautions like securities or other effective anti-thief actions. The
lightning rod is well connected to the ground, the ground bus' diameter must be more than 5mm.
For seismal zones, there must be anti-earthquake measurements, like fixed balustrade for the
rack.

2. Device Installation

2.2 Preparations
2.2.1 Network Resources
GS8 shall be connected with intra-company network or Internet for different usages. Test your
network connectivity and provide a port for this equipment. It is usually connected to a switch or
a router.
2.2.2 IP Address
Get an IP address for your GS8. the setting of IP address, see 3.1.1set GS8's IP address.
Note: Static IP address is recommended, no matter public or private address. (except DDNS ).
2.2.3 Ethernet Cable
Get a standard RJ-45 cable for GS8.
2.2.4 External Line
2FXO card is necessary if you want to call PSTN from GS8, connect its FXO port with PSTN with
a cable.
Prepare a GSM card if you want to call mobile phones from GS8.
2.2.5 Other Soft-switch Accounts
Ask for soft switch accounts and register information like phone number, password, register proxy
address, proxy address, register port, external proxy address, register expiration time etc.
2.2.6 Network Topology
Build your network topology based on GS8's location and connectivities.
2.2.7 Line Adjustment
Extend the external lines and cables to reach GS8's ports, if they are too far from the equipment.
2.3 Installation Procedures
GS8 equipment shall be placed on a table or a rack, install it as below steps.

2. Device Installation
10
Note: Do not put any heavy thing on the equipment to avoid any damage of the base.
2.3.1 Network Connection
Connect the cable with Ethernet LAN port on the back side.
2.3.2 Connect out Line
•Connect analog line with the port of 2FXO card on GS8
•If there is a GSM/CDMA card, connect an antenna with GSM/CDMA port. Better way is with
a coaxial cable.
•If there are several wireless cards, these cards may share one public antenna.
2.3.3 Power Connection
1. Connect the power line with the power port on the back side.
2. Connect the other end with outlet nearby.
2.3.4 Power On
After all these steps, power on.
All LED indicators are off at the beginning, then the power indicator is green all the time.

3. Web Management System

Chapter 3
Web Management System
3.1 Login
Login to GS8 Web Server with IE browser (1024*768 recommended) and make configurations
like this:
1. Open IE browser and enter IP address in the address field.
GS8 has a default address: 192.168.0.100. If the default address has been changed, gain it like
below: ( if you can not login, see 3.1.1 change GS8's IP address)
•Dail “***” and input password "23646" when you hear the dialing tone of AA after calling
in through FXO port of GS8, and the equipment will show you the IP address. the
SpreeCode and password used here are default, you may change them on the page of
AA at Call Settings-System Settings after loging into the web management system.
•Or Press Reset button for 6 seconds and reset the configurations to the factory default
(including the IP address recovered to default 192.168.0.100 ).
Note: The Reset button will reset all configurations, not only the IP address.
2. Input user name and password in the pop-up window. ( see figure 3-1)

3. Web Management System

•Administrator: the default user name and password is "admin".
Change administrator's password in the Adminstration > Change Password menu after login.
3.1.1 Change GS8's IP Addresss
Any operation (including initialization) on configurations shall be made in the GS8's web
management system. You can not login to the system if your PC's IP address does not belong to
the same network segment as the equipment's. So the simplest way is to change your PC's IP
address.
As below:
1. Change your PC's IP address to the same network segment (for example: 192.168.0.120 )
2. Login to GS8: visit the default "192.168.0.100" with IE browser and login with "admin".
3. Click and enter Administration> Network Setting menu, change the IP Address, Net
mask, Default gateway and DNS based on your real situation.

4.2 Line Status
Trunk lines are very important basic resources for GS8 system. All calls must have trunk lines to
be made. GS8 has two kinds of trunk line: IP line and interface card line. You must use SIP
protocol to make a call on IP line, you may add, delete, or modify IP line by yourself. Maximal
capacity is 10 register IP lines and 10 unregister IP lines. Interface card line is the lines which
provided by interface card. Now we have GSM/CDMA and FXO cards. The number of interface
card lines is fixed since the card is fixed, so you can not add, or delete any interface card lines,
but only change the settings.
The system will monitor all these lines' status, and provide monitor information to the
administrator for management.
Monitor > Line Status menu monitors all trunk lines, and classifies them into IP Line, PSTN Line
and GSM/CDMA line as figure 4-2.
