Chapter 5 — Regulatory information

This chapter includes regulatory information for American, Canadian, and

International installations of the Option 11C Mini.

System approval

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.

Notice for United States installations

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.

Importance of Ringer Equivalence Number

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.
