Generally this telephone may be
connected to switchboards which
support tone signalling and timed
break recall. In the event of any
difficulties please consult your
switchboard service provider.
When you connect your telephone
to a switchboard, you can set the
switchboard's external line access
code so that when you make an
external call using the handset
directory or redial list the code is
automatically dialled before the
number. See your main Diverse
User Guide for details.
