8.1.2 Features in the Private Network
Here describes subscriber-related features in a PISN.
Standardized Operation and Signalling
The way in which a feature is actuated on the terminal and its signalling are iden-
tical whatever the network used (local, PISN or public network).
Scope of Performance
The range of services in a PISN is determined by the following criteria:
• Local features of the system
• Type of networking (QSIG or virtual with DSS1)
• Offer available from the public network provider
Networking with QSIG
The standardized QSIG protocol supports a wide range of basic and supplemen-
tary services. The system supports the following services:
•Call diversion
• Call transfer
•Hold
• Conference (three-party conference, variable conference, preconfigured con-
ference)
•Brokering
• Enquiry call
• Callback if busy
• Call forwarding
• Do not disturb
•Recall
Under QSIG the activated feature is displayed on the system terminals (excl.
Office 10 and Office 20), e.g. "On hold" or "Conference".
