ISDN Feature Descriptions

Addressing

The UNIVERGE NEAX 2000 IPS supports E.164 numbering plan as Type of Number (TON) / Numbering Plan Identifier (NPI) combination in Calling and Called Party Number Information Element for ISDN calls.

Advice of Charge - Display

When an outgoing connection is made on the ISDN trunk, this feature provides the call originator with the charge information form the network. The information will be displayed on the calling Dterm LCD for six seconds after the station has been released, and be output to the SMDR port.

Call-By-Call Service Selection

Services can be selected on a call-by-call basis to all channels of a single PRI interface according to applications. Services may be used on any available channel, unlike Trunk Provisioning Service, in which services are assigned to specific channels.

Called Party Recognition Service (Direct-In Termination (DIT))

This feature provides an incoming Direct-In Termination (DIT) call via an ISDN trunk to be connected to a predetermined station. This application can be used for a station or modem.

Channel Negotiation

When collisions of data occur between an outgoing call to ISDN and an incoming call from ISDN, the B channel that 2000 IPS specified will be busy on the network and the network will specify another B channel. This feature provides negotiation for the selection of a B-channel between the 2000 IPS and the network, when the SETUP message is delivered.

Connected Line Identification Presentation (COLP) / Connected

Line Identification Restriction (COLR)

Connected Line Identification Presentation (COLP) provides the 2000 IPS to send the ISDN number of the connected party in the 2000 IPS, to the calling party. Connected Line Identification Restriction (COLR) provides the 2000 IPS to restrict presentation of the connected party’s ISDN number in the 2000 IPS, to the calling party.

CPN To Network–Present

This feature allows the ISDN network to be informed of the Calling Party Number (CPN) when a call originates from a terminal connected to the UNIVERGE NEAX 2000 IPS.

CPN To Terminating User–Display

This feature provides a visual display of the originating station’s number and sub-address information on a Multiline Terminal for incoming ISDN calls. This provides the terminal user with a quick and accurate way to identify the originating station’s number (Calling Number).

DID Addressing

This feature allows incoming ISDN-PRI calls to terminate to stations, Attendant Console, Automated Attendant, etc., based on the Called Party number. Direct Inward Dial trunks will be terminated to programmed destinations without Attendant assistance.

DID and DOD Addressing

This feature allows the system to use DID and DOD on the same B-Channels. Trunk Provisioning Service election is not required. (B-Channels can be used for DID and DOD without separating the trunk routes.)
