QSIG global networking
Lucent Technologies is the first vendor to provide compatibility with the QSIG
global networking protocol. This means you can connect the system with other
systems throughout the world. QSIG Global Networking was developed 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 system to system as long as both systems support the
same protocol.
QSIG is the generic name for a family of signaling protocols. The Q-reference
point or interface is the logical point where signaling is passed between two peer
entities in a private network.
DEFINITY BCS and GuestWorks supports only the QSIG Basic features, which
are voice and data basic call setup with Number Identification and Transit
Counter. QSIG Number Identification allows a switch to send and receive the call-
ing number, and displays up to 15 digits for the calling and connected numbers
across ISDN-PRI interfaces.
World Class Routing
The system has been designed to be a world-class system that meets the needs
of all customers. One capability essential in meeting those needs is the ability to
dial any location in the world, regardless of the dial plan used at that location. In
recognition of this requirement, the system has been designed with World Class
Routing.
World Class Routing is a powerful enhancement to the system’s call-routing capa-
bilities. ARS links several call-routing features to build a communications network
capable of providing flexible call routing for any type of dialing plan, while accom-
modating changes in both international and local dialing plans.
The following are key components of World Class Routing:
■ Digit Conversion converts a dialed public network number into a private
network number and vice versa. Dialed numbers matching entries in the
digit conversion tables are treated and converted. Converted calls can be
routed via the most optimum route, resulting in reduced network charges
and appropriate use of the private network.
■ Toll Analysis compares a dialed number to entries in the system’s list.
Based on the results, calls may be restricted from completion.
■ Automatic Route Selection digit analysis compares a dialed public network
number with entries in the system’s tables, mapping the number to a
selected public network routing pattern.
