FCC Part 68: Requirements For End Users
This equipment complies with Part 68 of the FCC regulations. On the bottom of the unit is an
equipment label that contains, among other information, the FCC registration number (AP3USA-
61274-DD-N) and Ringer Equivalence Number (REN) which is 0.2B for the Analog IDBU. If
requested, provide this information to your telephone company.
The REN is useful to determine the quantity of devices you may connect to your telephone line
and still have all of those devices ring when your number is called. In most but not all areas, the
sum of the RENs of all devices should not exceed five (5.0). To be certain of the number of
devices you may connect to your line, as determined by the REN, call your local telephone
company to determine the maximum REN for your calling area.
Before connecting your unit to the lines, you must inform your local telephone company of the
jack (connector), Facility Interface Code (FIC), and Service Order Code (SOC) required for your
unit, as follows:
Operation Jack
FIC SOC
