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 7-1shows 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.
