System approval

Notice for United States installations

Importance of Ringer Equivalence Number

This chapter includes regulatory information for American, Canadian, and
International installations of the Option 11C Mini.
All global markets approve the Option 11C Mini system. The Option 11C
Mini has a regulatory label on the back of each system chassis. This label
contains national and international regulatory information.
The Option 11C Mini system follows Part 68 of the FCC rules. A label
containing the FCC registration number and Ringer Equivalence Number
(REN) for the Option 11C Mini equipment is on the back of each system
chassis. Provide this information to your telephone company, if it requests
FCC registration number and REN information.
The FCC regulation label includes the Ringer Equivalence Number (REN).
This number represents the electrical load applied to your telephone line after
you plug the PBX into the wall jack. The telephone line for your premises
does not operate correctly if the total ringer load exceeds the capability of the
telephone company's Central Office (CO) equipment. If there are too many
ringers connected to the line, there may not be enough energy to ring your
system. If the ringer load exceeds the system's capabilities, you may also
have problems dialing telephone numbers.
For more information about the total REN permitted for your telephone line,
contact your local telephone company. However, as a guideline, a total REN
of five should allow for normal operation of your equipment.
