PRI Endpoint

Last Updated : Oct 29, 2012 |

Administers PRI Endpoints for the Wideband Switching feature.

Note:

A PRI Endpoint with a width greater than 1 can be administered only if Wideband Switching has been enabled for the system.

A PRI Endpoint is an endpoint application connected to line-side ISDN-PRI facilities and has standard ISDN-PRI signaling interfaces to the system.

A PRI Endpoint is defined as 1 to 31 adjacent DS0s/B-channels, addressable via a single extension, and signaled via a D-channel (Signaling Group) over a standard T1 or E1 ISDN-PRI interface.

Example command: add pri-endpoint n, where n is the extension number.

COR

Valid Entry

Usage

0 to 995

The class of restriction (COR) used to determine calling and called party privileges.

COS

Valid Entry

Usage

0 to 15

The Class of Service (COS) used to determine the features that can be activated by, or on behalf of, the endpoint.

Extension

The extension number used to access the PRI endpoint.

Maintenance Tests

If enabled, runs hourly maintenance tests on this PRI Endpoint.

Name

The name of the endpoint. Accepts up to 27 alphanumeric characters.

Originating Auto Restoration

If enabled, automatically restores calls originating from this PRI Endpoint (while maintaining endpoint call status) in the case of network failure if the call is over SDDN network facilities.

Signaling Group

Valid Entry

Usage

digits or blank

The D-channel or D-channel pair that provides the signaling information for the set of B-channels that make up the PRI Endpoint. For the maximum allowed entry, see Avaya Aura® Communication Manager System Capacities Table.

Simultaneous Calls

If enabled, specifies that multiple simultaneous calls can be placed to/from the PRI Endpoint.

TN

Use this field to specify a tenant number. You can enter a value from 1 to 250.

Width

Valid Entry

Usage

1 to 31

The number of adjacent DS0 ports beginning with the administered Starting Port, that make up the PRI Endpoint. This field cannot be blank. A width of 6 defines a PRI Endpoint that can support data rates up to 384 Kbps.

WIDEBAND SUPPORT OPTIONS

Contiguous

Available only if “N by DS-zero” (NXDS0) multi-rate service is enabled.

Valid Entry

Usage

y

Specifies the floating scheme. NXDS0 calls are placed on a contiguous group of B-channels large enough to satisfy the requested bandwidth without constraint on the starting channel (no fixed starting point trunk). Unavailable with H0 ISDN information transfer rate.

n

Specifies the flexible scheme. NXDS0 calls are placed on any set of B-channels on the same facility as long as the requested bandwidth is satisfied. There are no constraints, such as contiguity of B-channels or fixed starting points

H0

If enabled, specifies the ISDN information transfer rate for 384 Kbps of data, which is comprised of six B-channels. When a PRI Endpoint is administered to support H0, the hunt algorithm to satisfy a call requiring 384 Kbps of bandwidth uses a fixed allocation scheme.

H11

If enabled, specifies the ISDN information transfer rate for 1536 Kbps of data, which is comprised of 24 B-channels. When a PRI Endpoint is administered to support H11, the hunt algorithm to satisfy a call requiring 1536 Kbps of bandwidth uses a fixed allocation scheme.

H12

If enabled, specifies the ISDN information transfer rate for 1920 Kbps data, which includes 30 B-channels. When a PE is administered to support H12, the hunt algorithm to satisfy a call requiring 1920 Kbps of bandwidth uses a fixed allocation scheme.

NXDS0

If enabled, specifies the NXDS0 multi-rate service.
