lines, inform them of:
T
The telephone number to which this unit is connected
T
The ringer equivalence number (see the modem label)
T
The USOC jack required.
T
The FCC Registration number (see the modem label).
The ringer equivalence (REN) is used to determine how many devices can be connected to
your telephone line. In most areas, the sum of the RENs of all devices on any one line
should not exceed five (5). If too many devices are attached, they may not ring properly.
