GDS-600 - General Description
3
Key highlights of the GDS-600 series include:
Economy and Efficiency
The base system is equipped to support with no trunk or station interfaces. The system may be configured to a
maximum of Forty (40) CO lines, or 15 VOIP lines (VIU version) OR 40 VOIP lines (ITU version) in the 80 port
and Twenty four (24) CO lines or 15 VOIP lines in the 64 port cabinet / six (6) ISDN BRA’s or Thirty ISDN PRI
Channels. Station cards may be selected to allow practically any combination ranging from all HYBREX DK-X
Digital Sets to all industry standard Single Line Telephone sets, or Hybrex VOIP phones with a combination of the
three types. This makes the system cost effective at the initial phase and when expanded to it's maximum
capacity. This allows a wide variety of applications for the system to work effectively.
Easy Installation
“Factory Ready” - All GDS-600 Telephone systems are "ready to go" right out of the box. A well thought out
default database is factory installed on each system which meets the needs for most installations. This
alleviates hours of on site time, minimizing installation costs for both dealer and customer.
“Small & Compact” - The Key Service Unit's small size takes little space for installation.
Easy Maintenance
Solid-state design minimizes trouble and eliminates periodic maintenance.
Easy Expansion. Various plug in Interface Cards for simple, modular expansion.
Versatile programming and options for ease of setup.
Database Flash Memory Back Up - Customer data is backed up when the power is turned off and there is
no battery to replace.
Battery Back Up (System Operation) - GDS-600 systems can be equipped with an optional battery back up
which keeps the system operational for a minimum 1 hour in the case of a commercial power failure.
Customer Care Programming - Customers and service personnel can easily communicate and perform
programming right over the telephone. HYBREX telephone systems allow programming and voice
conversations to be performed at the same time.
Advanced software upgrades –Through the RS232 / LAN / Internet(TCP/IP) connection, system software
can be upgraded easily without replacing any firmware.
Flexibility of System Applications
Unlike other conventional systems in the GDS-600 size range, the installer will find an unprecedented range of
customer database programmability. In "system parameters" there are extensive options for various timing
settings related to features. An array of parameters are programmable for signaling options on outside lines and
internal single line telephone sets. The installer may Enable/Disable many system wide features. And in class of
service, there are over 30 options for each station providing maximum flexibility for nearly any application.
Varied Extension Alternatives
You can connect an ISDN Modem, ISDN phone, proprietary HYBREX DK series KeyPhones, Voice Over Internet
Protocol (VOIP), Access Control Phones (ACP), Door Phone and conventional industry standard single line
sets –Modem, Answering Machine, Cordless phone, etc. directly to the KSU. This feature provides you with the
choice to select different extension equipment to suit individual applications.

Installation
Caution 1. This system should be installed by qualified service personnel.
2. Do not install the Power Supply unless you have read the following instructions and
completed all the installation and wiring.
3. STATIC SENSITIVE DEVICES! Please handle with care.
Installing the Equipment
Backboard
Be sure to plan and allow enough space to mount and
connect the key service unit, power supply and system
battery back up if applicable.
Key Service Unit
Use the enclosed Hanging Template to locate the
mounting position for the Key Service Unit. Drill
appropriately spaced holes to fix the Hanging Template
and mount the KSU on the wall. When mounting the
KSU, make certain that there is adequate room for the
future system expansion and that the connecting power
cable between the power mains and the KSU. The same
applies for the battery back up unit.
Power Source
Dedicated Power Source - The power cord must be connected to a dedicated AC outlet.
Be sure that the third wire earth ground of the AC circuit is connected to a good electrical ground. If a music
source is installed, it must be connected to a separate AC circuit rather than the system's dedicated AC line cord.
Check Your Voltage Selection Jumper
Verify that the input voltage and input voltage jumper are correct before you power on the system. The input
voltage is set according to the Customer's requirement before shipping. However it is important to verify that the
setting is correct prior to initial system power up.
Power Supply voltage options for the unit:
100-VAC: 100 to 120 V AC (50/60Hz) or 240-VAC: 205 to 265 V AC (50/60Hz).
