Connection and conditions for use
You can connect your
e
900 to a direct exchange line (DEL) — a line
connected to a local exchange, with its own phone number; to an
extension socket connected to a DEL; or to an extension on an
approved compatible PBX. Do not connect the
e
900 as an extension
to a payphone.
The
ringer equivalence numbers (RENs)
of all instruments (phones,
fax machines, etc.) connected to an exchange line
must not add up to
more than 4
— otherwise, one or more of them may not ring and/or
answer calls correctly. The
e
900 has a REN of 1, and most other
telephones have a REN of 1 unless marked otherwise.
