DEFINITY ONE DCS networks
If your company has two or more sites with DEFINITY ONE, you can network them
together using the DCS over ISDN-PRI feature (DCS+). This requires a system to use
ISDN-PRI signaling. The network connections can be either ISDN-PRI or DS1
private-network dedicated facilities. Figure 7-1 shows a network using ISDN-PRI
signaling.

QSIG global networking
DEFINITY ONE is a pioneer in providing compatibility with the QSIG global
networking protocol. This means that you can connect DEFINITY ONE with other
switches throughout the world. Avaya developed the QSIG Global Networking
feature to comply with the QSIG standards developed by the European Computer
Manufacturer’s Association and the International Standardization Organization. It
supports the ISDN-Primary Rate Interface connection from switch to switch as long
as both switches support the same protocol.
Avaya’simplementation of QSIG features the Name Identification supplementary
service and the Call Forwarding and Call Transfer features. QSIG enables the system
to move calls from their original paths to new paths that cost less or use resources
more efficiently. New paths can be set up after a call has been transferred or after a
call has been forwarded using the Diversion with Rerouting feature. DEFINITY
ONE’s implementation of QSIG also supports the ISO QSIG private network
diversion supplementary service, as described in the QSIG standard.
