Government Requirements
Certain governments require that instructions pertaining to connection to the telephone
network be included in the user documentation. Specific instructions are listed in the
following sections.
United States
Notice to Users of the Telephone Network
This equipment complies with Part 68 of the FCC rules. On the back of the access
carrier is a label that contains, among other information, the FCC registration number for
this equipment. If the unit comes with an integral modem, the Ringer Equivalence
Number (REN) will also be labeled. If requested, please provide this information to your
telephone company.
The REN is used to determine the number of devices that may be connected to the
telephone line. Excessive RENs on the line may result in the devices not ringing in
response to an incoming call. In most, but not all areas, the sum of RENs should not
exceed five (5.0). To be certain of the number of devices that can be connected to the
line, as determined by the total RENs, contact the local telephone company.
If your unit causes harm to the telephone network, the telephone company may
discontinue your service temporarily. If possible, they will notify you in advance. But if
advance notice is not practical, you will be notified as soon as possible. You will be
advised of your right to file a complaint with the FCC.
Your telephone company may make changes in facilities, equipment, operations, or
procedures that could affect the proper operation of your equipment. If so, you will be
given advance notice so as to give you an opportunity to maintain uninterrupted service.
No repairs may be performed by the user. Should you experience difficulty with this
equipment, refer to
Warranty, Sales, Service, and Training Information
on page 20.
For Digital Data Service (DDS) installations, inform the local telephone company of the
appropriate facility interface code for the service you desire.
