36 Identification Elements
syd-0200/3.0 – I7.9 – 11.2009
Calls with the Internal ringing pattern:
• Calls from internal users
• Calls from the public network if Ringing pattern = single ringing tone is set in the
terminal configuration (setting for analogue terminals only).
Calls from users from the private network (PISN users):
– Calls from the private leased-line network
– Calls from virtual network PISN users
• An enquiry call from a user with an exchange call on hold if the parameterRing-
ing pattern at enquiry destination = internal is set in the common settings of the
user configuration (see "Hold (enquiry call)", page 349).
Calls with the External ringing pattern:
• Calls from the public network
– if they do not originate from a virtual network PISN user and
–if Ringing pattern = automatic is set in the terminal configuration (setting for
analogue terminals only).
• An enquiry call from a user with an exchange call on hold if the parameterRing-
ing pattern at enquiry destination = external is set in the common settings (see
"Hold (enquiry call)", page 349).
The Ringing pattern at enquiry destination setting is valid throughout the system.
Note:
Certain terminals which automatically answer calls (e. g. fax machines)
are not able to interpret the double ringing tone correctly. With these ter-
minals the configuration Ringing pattern = automatic can be used to force
a situation where the single ringing tone is always used for all calls.
