5. 2. 4 Other Trunk Group Functions and Settings
Name of the trunk group
Each trunk group can be given a name. The name's main purpose is to provide orien-
tation It is displayed on some system phones whenever an outgoing connection is set
up.
Tip:
It is a good idea to name trunk groups according to the origin of their lines (e.g. "Public ISDN",
"Analogue", "Leased Line Geneva", etc.). This ensures greater clarity during configuration work.
Generating a Ring-back Tone
With the settings Ring back tone for incoming calls and Ring back tone for outgo-
ing calls the control of the generation of ring back tones on digital trunk connections
can be limited by the system. These settings do not have to be altered in normal oper-
ation.
• In the case of a stand-alone communication server on the public network the ring-
back tone is supplied by the local exchange and does not have to be generated by
the communication server.
• In a PISN with QSIG networking the ring-back tone always has to be generated in
the destination PINX. In this case the setting Ring back tone for incoming calls =
Generate is set permanently and cannot be altered.
Here are two applications in which the settings do have to be adapted:
• In a PISN with networking via DSS1 protocol the ring-back tone is normally also
generated in the destination PINX ( Ring back tone for incoming calls = Gener-
ate). There are however exceptions (e.g. communication server integrated in Cen-
trex
1)
) where the ring-back tone does not have to be generated internally. In these
cases, choose the setting Ring back tone for incoming calls = Do not generate.
• It is possible that the destination does not generate a ring-back tone. (e.g. external
IP gateways). In such cases it is possible to generate the ring-back tone locally. For
this choose the setting Ring back tone for outgoing calls = Generate.
Note:
If several PINXs are cascaded, generate the ring-back tone only once whenever possible
and as close to the called user as possible.
