carpets or other surfaces which

its surfaces.

How many phones can you have?
All items of telephone equipment have
a Ringer Equivalence Number (REN),
which is used to calculate the number
of items which may be connected to
any one telephone line. The Synergy
2120 has a REN of 1. Any other
instrument provided by BT may be
assumed to have a REN of 1 unless
otherwise stated. A total REN of 4 is
allowed.
Connection to the BT telephone

provide Multi-frequency (Touch Tone)

It may be connected to Direct Exchange
Lines and switchboards (PBXs) with
new plan (plug and socket)
arrangements.
Connecting to switchboards
Synergy 2120 is only approved for use
with a compatible switchboard
including those which do not provide
