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 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, y
ou should contact your equipment supplier in the first instance.’
ISDN Installation
For the ISDN unit (G2-SIU), GDS-600 only offers ISDN S/T interface connection behind an NT1 device. It
can not be connected to a “U” interface directly.
