Connection and conditions for use
You can connect your iDECT X2 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 iDECT X2 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 iDECT X2 has a REN of 1, and most other
telephones have a REN of 1 unless marked otherwise.
