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. This chapter also provides
other information related to the Option 11C Mini system installation.
Refer to "Appendix A – General information for the United Kingdom" on
page 347 for additional regulatory information for the UK. Refer to
"Appendix B – Additional information for installations in Germany" on
page 411 for additional regulatory information for Germany.
The Option 11C Mini system complies with Part 68 of the FCC rules. A label
containing the FCC registration number and Ringer Equivalence Number
(REN) for this equipment is on the back of each system chassis. If requested,
you must provide this information to the telephone company.
The FCC regulation label includes the Ringer Equivalence Number (REN).
This number represents the electrical load that will be applied to your
telephone line after the PBX is plugged into the wall jack. The telephone line
serving your premises will not operate correctly if the total ringer load
exceeds the capability of the telephone company's Central Office (CO)
equipment. That is, if too many ringers are connected to the line, there may
not be enough energy to ring your system. If the ringer load is excessive, 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 normal operation of your equipment.
