Using the XE1414B in the US
All equipment connected to the public telephone network in the
United States must have FCC Part 68 Registration. Part 68
registration certifies that the device will not cause harm to the
telephone network. The XE1414B provides a user transferable
FCC Registration. This permits XE1414B customers to use
our FCC registration number without submitting their systems
for additional testing. Call Xecom technical support at 408-
945-6640 with any questions on whether your system qualifies
to use Xecom's FCC Registration Number.
In your operating instructions you must provide certain infor-
mation to the end user of the modem. The instructions should
include most of the instructions shown below. Only the
information regarding the mounting of the device in the final
assembly should be omitted.
FCC Instructions:
This product complies with Part 68 of the FCC Rules and
Regulations. On each device shipped, there is a label which
contains, among other information, the FCC Registration
Number and Ringer Equivalence Number (REN) for this
product. You must, upon request, provide this information to
your telephone company.
The mounting of this device in the final assembly must be made
in such a manner as to preserve the high voltage protection
between the TIP/RING Connection and the rest of the system.
Typically, this may be accomplished by maintaining a minimum
spacing .100 mils between the TIP/RING Traces to the RJ-11C
Jack and low voltage portion of the system. No additional
circuitry may be attached between TIP/RING and the telephone
line connection, unless specifically allowed in the rules.
Your telephone company may make changes in its facilities,
equipment, operations or procedures that could affect proper
functioning of your equipment. If they do, you will be notified
in advance to give you an opportunity to maintain uninter-
rupted telephone service.
If you experience trouble with this device, please contact
XECOM at (408) 945-6640 for assistance. The telephone
company may ask you to disconnect this device from the
network until the problem has been corrected or until you are
sure that the device is not malfunctioning.
The device may not be used on coin service lines provided by
the telephone company (this does not apply to private coin
telephone applications which use standard telephone lines).
Connection to party lines is subject to state tariffs.
FCC Labels:
FCC rules also require a label which is visible from the outside
of the equipment. The label should display Xecom's name as
holder of the FCC Registration, the FCC Registration Number
and Ringer Equivalence of the modem. This is the same
information which appears on the top of each XE1414B
module.
The REN is useful to determine the quantity of devices you
may connect to a telephone line and still have all of these
devices ring when the number is called. In most, but not all
areas, the sum of the RENs 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 the line, as determined by the REN,
you should contact the local telephone company to determine
the maximum REN for your calling area.
If your system causes harm to the telephone network, the
telephone company may discontinue service temporarily. If
possible, they will notify you in advance. If advance notifica-
tion is not practical, you will be notified as soon as possible.
