BABT/SITS/82/005S/D
a. The modem is suitable for connection to the Public Switched Telephone Network
(PSTN) provided by British Telecommunications plc or Kingston Communications
(Hull) plc. Circuit supply by British Communications, Mercury Communication, or
Hull City Council. Only direct exchange lines may be used, not shared service.
b. The modem is suitable for household, office, and similar general indoor use. It is
not suitable for use as an extension to a pay phone.
c. BT lines supplied must support either loop disconnect or multifrequency tone
signaling.
d. REN (Ringer Equivalence Number).
The REN value of a unit is calculated from 3/n where n is the total number of units
which can be connected in parallel which will still cause the standard bell (as
defined in BS6305 Appendix D) to ring.
REN values of less than 0.3 cannot be assigned.
For apparatus which is not capable of forming part of multiple installation, a REN
value of 3 is assigned.
REN = 1
If a telephone or other device is connected in parallel with the modem, the
combined REN must not exceed 4. A BT supplied telephone may be assumed to
have REN of 1.0 unless otherwise noted.
The approval of this modem for connection to the British Telecom public switched

ii. external control software or external control apparatus which cause the operation
of the modem associated call set-up equipment to contravene the requirements
