4.4.2 Connection between Protocol and Range of Services
Available
The range of services available in a PISN is determined by the protocol used and
the local features of the system. The services offered under QSIG / PSS1 and DSS1
differ only marginally. With virtual networking the range of services available also
still depends on the public network provider. The system supports a multitude of
the ISDN services on offer and combines them effectively with its own features.
Digital networking is based on the ISDN standard and therefore supports both
voice and data traffic.
4.5 Connecting PISN Nodes
The nodes of a PISN (PINX) can be connected via basic, primary-rate or Ethernet
accesses. For short distances the connection can consist of one copper cable with-
out any ancillary equipment. For longer distances transmission equipment or
leased lines of the public network need to be used.
