Appendix C - Regulatory Information

FCC Regulations for Telephone Line Interconnection

1.This equipment complies with Part 68 of the FCC rules. On the outside surface of this equipment is a label that contains, among other information, the FCC registration number and ringer equivalence number (REN). If requested, this information must be provided to the telephone company.

2.As indicated below, the suitable jack (USOC) connecting arrangement for this equipment is shown in Appendix B. If applicable, the facility interface codes (FIC) and service order codes (SOC) are also indicated.

3.The ringer equivalence number (REN) is used to determine the quantity of devices which may be connected to the telephone line. Excessive REN’s 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 REN’s should not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as determined by the total REN’s, contact the telephone company to determine the maximum REN for the calling area.

4.If this equipment causes harm to the telephone network, the telephone company will notify you in advance. But if advance notice isn’t practical, the telephone company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.

5.The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the equipment.
