Connecting to switchboards
The Diverse 2000 Executive Handset is
only approved for use with a base which
is compatible with switchboards,
including those which do not provide
secondary proceed indication. If you
would like a list of suitable switchboards,
contact BT on 0800 800 154. If you
do have a compatible switchboard, it
cannot be guaranteed that the telephone
will operate correctly under all possible
conditions of connection. If you have any
difficulties, contact BT as above or the
Diverse Helpdesk 0345 90 80 70.
Generally Diverse systems can be
connected to any switchboard where a
simple modern telephone can be used
to make and receive calls. The Diverse
system is suitable for connection to
switchboards which return secondary
proceed indication.
