ARS Node Identities

Purpose:

The ARS Node Identities form provides a means of assigning a directory number or identifier, and synonyms of that directory number, to systems operating as tandem switches with line terminations. Incoming digit strings are analyzed for the node identifiers defined in the top part of this form. If the primary node identifier or one of the synonyms for the system is detected, the call is routed to the appropriate local station; otherwise, the call is forwarded to the next node. The lower part of the form contains the mapping between leading digits supplied by the network, and the digits that must be dialed on this node to reach the other node.

Use this form when performing the following tasks:

Field Descriptions

Parameter

Description

Default Value

Directory Number (DN)

The Primary DN (Directory Number 1) displays the Primary Node Identifier (PNI) for this system.  

You can enter the Primary DN (Directory Number 1) and any secondary node identifiers, for a total of up to five entries. Each entry can contain up to 7 digits. The Local ID Index, Remote Node Leading Digit, or ARS Digits can contain digits from 0 to 9, and #. Note that the # character should only be used when the network consists entirely of MITEL systems.

The PNI must be unique at each non-clustered element in the network. However, in a given cluster, the clustered elements share the same PNI. You should only assign PNIs to a cluster if the cluster is connected in a MSDN/DPNSS network.

A PNI cannot appear as a directory number or as an ARS string on any of the systems in the network. Use the "Locate Number" maintenance command to determine if the PNI is a number that is already used on any of the other elements in the network.

You can also enter the PNI from the

  • Cluster Elements form for clustered elements

  • Network Elements form for the local element if the local element does not belong to a cluster.

System Default

Node ID Index

System-generated, protected field. Uniquely identifies the entry.

 

Remote Node Leading Digits

Enter the leading digits supplied by the DPNSS network for each remote node/system in the network. Up to 50 entries may be made, and there may be more than one entry for each node.

Blank

ARS Digits

Enter the actual digits that must be dialed in order to reach the specified remote node from this node. If there are alternative ARS Digits for the same node, another entry must be made.
