PBX Networking
PBX Networking
Forum 5004/5008/5012 provides all the features necessary for PBX
networking. You need PBX networking in the following cases:
●
To operate the Forum 5004/5008/5012 as a subsidiary system on
another PBX. This will also allow you to use the Forum 5004/5008/
5012 as a DECT server, for example.
●
To network several Forum 5004/5008/5012s into a PBX system.
●
To use flexible configuration possibilities of trunk lines for a Forum 5004/
5008/5012.
All settings that affect the configuration of PBX networking can be found in
the Configurator menu
Telephony: Trunks
and in the
Telephony: Settings
dialogue under
QSIG linking
. Refer also refer to the corresponding help topics
in the Forum 5004/5008/5012 online help.
You can use ISDN point-to-point connections (Q.SIG or DSS1 protocol) or IP
connections (Q.SIG-IP or SIP tie line protocol) for TK system networking.
Note:
If you do not need the features of PBX networking, the
simplified configuration is sufficient in most cases. For this
purpose, assign the preconfigured truck group (bundles)
Multi-
terminal access
or
System access
to the ports. The precon-
figured route called
External trunk
now makes it possible to
seize an external line immediately or by first dialling the prefix
“0”. You can rename the preconfigured bundle and the precon-
figured route if required, but you cannot delete them.
