GDS-1280N - General Description
1
General Description - Introduction
The General Description section contains an easy to understand overview of the HYBREX®GDS-1280
Enterprise Communication System. It is the intent of this document to provide both technical and non technical
readers with information pertaining to the system building blocks, capabilities, key highlights, electrical, physical
and environmental characteristics of the HYBREX GDS-1280 Enterprise Class Communication System.
FCC Rules and Regulation
In compliance with the requirements of Part 68 of the Federal Communications Commission Rules and
Regulations for connection of terminal system equipment to the telephone network and for your convenience, the
following information is presented.
FCC Registration Number
The HYBREX GDS-1280 is registered with the FCC in a dual registration capacity enabling the system to
operate as a key system only or as a hybrid system. The FCC Registration Numbers are US: 3A7MF03BGDS-
600 for key systems registration and US: 3A7KF03BGDS-600 for hybrid operation.
Ringer Equivalence Number
Ringer Equivalence 0.3B.
Notification of the Telephone Company
Customers connecting terminal equipment to the telephone network shall, upon request of the
Telephone Company, inform the Telephone Company of the particular line(s) to which such
connection is made, the FCC registration number and ringer equivalence number (REN) of the
registered terminal equipment.
The REN is useful to determine the quantity of devices you may connect to your telephone line
and still have all of those devices ring when your telephone number is called. In most, but not
all areas, the sum of the REN's of all devices connected to one line should not exceed five
(5.0). To be certain of the number of devices you may connect to your line, as determined by
the REN, you should contact your local telephone company to determine the maximum REN
for your calling area.
This equipment is capable of providing users access to Interstate providers of operator
services through the use of access codes. Modification of this equipment by call aggregators to
block access dialing codes is a violation of the Telephone Operator Consumers Act of 1990.
Direct Connection to a Party-Line or Coin Operated Telephone Line is Prohibited.
Incidence of Harm to the Telephone Lines
Should terminal equipment cause harm to the Telephone Network, the Telephone Company shall, where
practical, notify the customer that service may be temporarily discontinued. However, where prior notice is not
practical, the Telephone Company may temporarily discontinue service, if such action is reasonable in the
circumstances. In case of such un-notified temporary discontinuance of service, the Telephone Company shall:
(a) Promptly notify the customer of such temporary discontinuance of service.
(b) Afford the customer the opportunity to correct the situation which gave rise to the temporary
discontinuance.
(c) Inform the customer of the right to bring a complaint to the FCC pursuant to the procedures set
out in Subpart E of Part 68 of FCC Telephone Equipment Rules.

2
Compatibility of the Telephone Network and Terminal Equipment.
(a) Availability of telephone interface information.
Technical information concerning interface parameters and specifications not specified in FCC
Rules, including the number of Ringers which may be connected to a particular line, which is
needed to permit Terminal Equipment to operate in a manner compatible with Telephone
Company communications facilities, shall be provided by the Telephone Company upon
customer's request.
(b) Changes in Telephone Company Communications Facilities, Equipment, Operations and
Procedures.
The Telephone Company may make changes in its communications facilities, equipment, operations or
procedures where such action is reasonably required in the operation of its business and is not inconsistent with
the rules and regulations in FCC Part 68 of the FCC Rules and Regulations. If such changes can be reasonably
expected to render any customer Terminal Equipment incompatible with Telephone Company Communications
Facilities, or require modification or alteration of such Terminal Equipment, or otherwise materially affect its use
or performance, the customer shall be given adequate notice in writing to allow the customer an opportunity to
maintain uninterrupted service.
Radio Frequency Interference
This equipment generates and uses radio frequency energy and if not installed and used properly and in strict
accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has
been type-tested and found to comply with the limits for a Class A computing device in accordance with the
specification in Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against
such interference in a residential installation. However, this is no guarantee that interference will not occur in a
particular installation. If this equipment does cause interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
Re-orient the receiving antenna.
Relocate the equipment with respect to the receiver.
Move the equipment away from the receiver.
Plug the equipment into a different outlet so that equipment and receiver are on different branch
circuits.
CTR 21 (98/482/EC) Declaration Network Compatibility
CTR 21 (98/482/EC) Declaration Network Compatibility, the equipment has been approved in accordance with
Council Decision 98/482/EC for pan-European single terminal connection to the public switched telephone
network (PSTN). However, due to differences between the individual PSTNs provided in different countries, the
approval does not, of itself, give an unconditional assurance of successful operation on every PSTN network
termination point. In the event of problem, you should contact your equipment supplier in the first instance.’
ISDN Installation
For the ISDN unit (G2-SIU/G2-PIU), GDS-1280 only offers ISDN S/T interface connection behind NT1 device. It
could not be connected to “U” interface directly.
