47 CFR Part 68 Telecom
1.
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA. Located
on this equipment is a label that contains, among other information, the FCC registration number and ringer
equivalence number (REN) for this equipment or a product identifier in the format US:AAAEQ##TXXXX. If
requested, this number must be provided to the telephone company.
2.
A plug and jack used to connect this equipment to the premises wiring and telephone network must comply
with the applicable FCC Part 68 rules and requirements adopted by the ACTA. It’s designed to be connected
to a compatible modular jack that is also compliant.
3.
The ringer equivalence number (REN) is used to determine the number of devices that may be connected to
a telephone line. Excessive RENs on a telephone 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 may be connected to a line, as determined by the total RENs, contact the local
telephone company. For products approved after July 23, 2001, the REN for this product is part of the
product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN
without a decimal point (
e.g.
, 03 is a REN of 0.3). For earlier products, the REN is separately shown on the
label.
