1. This equipment complies with Part 68 of the FCC
rules. On the equipment is a label that contains,
among other information, the FCC registration
number and ringer equivalence number (REN) for
this equipment. The label is located on the circuit

2. The Universal Service Order Code (USOC) for
Permissive mode is RJ21X. The Canadian
equivalent to the USOC is CA21A.

3. The Ringer Equivalence (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). T o be certain of the number of
devices that may be connected to the line, as
determined by the total RENs, contact the

telephone network, the telephone company will
notify you in advance that temporary
discontinuance of service may be required. But if
advance notice is not practical, the telephone
company will notify the customer as soon as
possible. Also, you will be advised of your right to

page of the transmission, the date and time it is
sent, and an identification of the business, or other
entity , or other individual sending the message,
and the telephone number of such business, or
