If requested, this information must be provided to the telephone company. The 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) . To be certain of the number of devices that may be connected to the line, as determined by the total RENs, contact the telephone company to determine the maximum REN for the calling area.  \nThis equipment uses the following USOC jacks: RJ11C.  \nAn FCC-compliant telephone cord and modular plug is provided with this equipment. This equipment is designed tobe connected to the telephone network or  \npremises wiring using a compatible modular jack which is Part 68 compliant.
