recognizes who the call is for. At users' lines to which fax machines or answering machines
are connected, code calling may not be allowed, since these devices take calls automatically
(see Chapter Setting Up Various Pieces of Equipment (Quick Configuration) on page I-40 in
the Installation and Configuration Manual). The following bell signals are available:
1
one long tone and one short one, pause.
2
one long tone and two short ones, pause.
3
one long tone and three short ones, pause.
4
one long tone and four short ones, pause.
5
one long tone and five short ones, pause.
Initiating code calling:
If you call somebody who is just making a call, you can reach them as soon as possible by
initiating a callback (callback on busy). In this connection, your call and that of other parties
is returned as soon as the other called party replaces the handset.
If you call an internal extension, you can – in addition to callback on busy – initiate a callback
on no response. In this case, you and the other parties are called as soon as your busy
called party has replaced the handset after completing his or her next call.

After replacing the handset, the tele-

With many ISDN telephones, the ringing rhythm is not affected; with others, however, the
system shows the code call on the display.
