DEFINITY ECS provides not only powerful voice and data capabilities, but con-
nections to a variety of voice and data networks as well. AT&T/Lucent Technolo-
gies has long been a leader in networking. DEFINITY ECS continues to build on 
those established networking strengths to offer you network management fea-
tures, network interfaces, a variety of private network configurations, and 
end-to-end ISDN capabilities. Lucent Technologies leadership in developing and 
supporting open international networking standards is also apparent in DEFINITY 
ECS’s compatibility with the QSIG global standards.

NOTE:
Some applications and products are unavailable in some countries. Please 
check with your local distributor for further information about which features 
and applications are available to you.

DEFINITY ECS was a pioneer in providing compatibility with the QSIG global net-
working protocol. This means you can connect the DEFINITY ECS with other 
switches throughout the world. Lucent Technologies developed QSIG Global 
Networking feature to comply with the QSIG standards developed by the Euro-
pean 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.

QSIG Global Networking has been continually refined with each DEFINITY ECS 
release. The Lucent Technologies implementation of QSIG features the Name 
Identification supplementary service and the Call Forwarding and Call Transfer 
features.
