equipment is a label that contains, among other information, the FCC registration
number and ringer equivalence number (REN) for this equipment. If requested,
this information must be provided to the telephone company.
The modem jack of this equipment complies with Sub-part F of Part 68 of FCC
The REN is used to determine the quantity of devices which may be connected to
the telephone line. Excessive RENs on the telephone line may result in the devices
not ringing in response to an incoming call. In most, but not all, areas the sum of
the RENs should not exceed five (5.0). To be certain of the number of devices that
may be connected to the line, as determined by the total RENs, contact the
telephone company to determine the maximum REN for the calling areas.
If the terminal equipment causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of service may
be required. But if advance notice isn't practical, the telephone company will notify
the customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it necessary.
