locally either via the keypad, in the case of the SOPHO-SET or SOPHO-LAM or interactively
from the keyboard of the data terminal.
It is also possible to program the option from the ISPBX. As the automatic answering option

The call forwarding facilities offered for voice calls are also available for data calls, see Facility
Implementation Manual, Voice Facilities.

CALL WAITING INDICATION
The call waiting facility is available for both voice and data calls, see Facility Implementation
Manual, Voice Facilities.
Note: A data terminal user cannot hear the call waiting tone burst and even the receipt of such
a tone burst by a data terminal can disturb the synchronisation of the connection. The tone
will not be sent to a busy terminal when the call of the busy DNR is data protected. A call
can be data protected in 3 different ways as discussed in the `data protected' facility.
Not only the call waiting tone burst is not sent towards the data terminal, it is even not
possible to break in or listen in on the connection by either operator or other extension
users.
When FCM 35 (call waiting protected) is assigned to a DNR the call waiting tone burst is
also not sent to the extension in case a call waiting is initiated for the busy extension.
Break-in by the operator is still possible and if the operator dials the extension the tone
burst is still sent.
