Private Network Access
8 —Private Networking Features
Private Network Access
Allows calls to other systems in a private network. These calls do not use the public
network. They are routed over your dedicated facilities.
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 ARS 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 allows 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 Number instead of a Route Pattern.
ATM-Port Network Connectivity
(ATM-PNC)
ATM Port Network Connectivity (ATM-PNC) provides an alternative to either the direct
connect or Center Stage Switch configurations for connecting the Processor Port
Network (PPN) to one or more Expansion Port Networks (EPNs). ATM PNC replaces the
Center Stage Switch in a DEFINITY R8r network with an Asynchronous Transfer Mode
(ATM) switch. ATM PNC is available with all three DEFINITY ECS reliability options —
standard, high, and critical.
ATM PNC integrates delivery of voice, video, and data via ATM over a common large
bandwidth LAN, providing reduced infrastructure cost and improved network
manageability. ATM PNC uses standards-based open interfaces that can be provisioned
with either new or existing DEFINITY ECS systems and is ATM-ready for future
expansion.
