Avaya IP600 DCS networks
If your company has two or more sites with Avaya IP600, you can network them
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 6 shows a network using ISDN-PRI
signaling.

QSIG global networking
Avaya IP600 is a pioneer in providing compatibility with the QSIG global networking
protocol. This means that you can connect Avaya IP600 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-PRI connection from switch to switch as long as both switches
support the same protocol.
Avaya’s implementation 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. Avaya IP600’s
implementation of QSIG also supports the ISO QSIG private network diversion
supplementary service, as described in the QSIG standard.
