Notice: The Ringer Equivalence Number (REN) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be
connected to a telephone interface. The termination on an interface may consist of
any combination of devices, subject only to the requirement that the sum of the
Ringer Equivalence Numbers of all the devices does not exceed 5.
The REN for the modem contained in this product does not exceed 1.0.

The modem is intended for only use in the Compaq Internet PC. For the purposes
of BABT approval, the modem is classified as a host-independent product.
The modem is suitable for connection to the Public Switched Telephone Network
(PSTN) direct exchange lines and relevant branch systems (PBXs).
A ringer equivalent number (REN) is a value given to all apparatus to be connected
to the PSTN. Its value can be taken and used to calculate the maximum number of
equipment items that can be connected in parallel without impairing the
performance of the standard bell circuit.
REN = 3/n where n is the maximum number of units that may be used in
1.
parallel.
The maximum REN of a line is 4; therefore, the total REN of all apparatus
2.
connected to the line (obtained by summing the individual REN values) should
not exceed 4. This value includes any BT provided instrument, each of which
is assumed to have REN value of 1.0 unless otherwise stated. Exceeding the
REN value of 4 may cause your telephone(s) to ring weakly or not ring at all.
