Private Networking Features
Issue 5 January 1998 A-47555-230-024
Extension Number Portability
Gives you the ability to assign any extension to any system in a subne twork. Sta-
tions can be moved across systems while retaining the original extension num-
ber, as long as the systems are part of a defined subnetwork. This feature is used
in conjunction with Automatic Alternate Routing and Un iform Dial Plan.
Inter-PBX Attendant Calls
Allows attendants for multiple branches to be concentrated at a ma in location.
Incoming trunk calls to the branch, as well as attendant-seek ing voice-terminal
calls, route over tie trunks to the main location.
Node Number Routing
Allows you to specify the route pattern associated with each node in a private
network. It is a required capability for Extension Number Portability and is used in
conjunction with Automatic Route Selection, AAR and A RS Partitioning, Private
Networking, and Uniform Dial Plan. Uniform Dial Plan extensions can be routed
to a specified node using its associated pattern. Node Number Routing all ows a
Uniform Dial Plan route pattern based on node numbers or on location codes. On
the AAR and ARS Digit Analysis Tables, you also can specify a Node N umber
instead of a Route Pattern.
Private Network Access
Allows calls to other systems in a private network. Thes e calls do not use the
public network. They are routed over your dedicated facilities.
QSIG
QSIG provides compliance to the International Organizat ion for Standardization
(ISO) ISDN-PRI private-networking specifications. QSIG is defined by ISO as the
worldwide standard for private networks.
QSIG is the generic name for a family of signaling protoco ls. The Q-reference
point or interface is the logical point where signaling is passed betwee n 2 peer
entities in a private network. QSIG signaling can provide fe ature transparency in
a single-vendor or multi-vendor environment.
QSIG provides call-related supplementary services. Thes e are services that go
beyond voice or data connectivity and number transport and display. Exam ples
of supplementary services include Name Identification, Call Forwarding
(Diversion), and Call Transfer.
