ISDN Features
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.
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 System.
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 Addressing 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.)
Event-Based CCIS
This feature allows a PBX customer who does not have a tie line (or when a customer cannot use the
tie line due to busy or fault of the line), to use the various CCIS feature by using the ISDN line as a
CCIS virtual tie line, on the IMX to NEAX2000 IPS connection or the NEAX2000 IPS to IPS
connection.
ISDN Terminal
This feature provides the system with an ISDN Terminal or Terminal Adapter (TA). ISDN Terminal
to ISDN Terminal, ISDN Terminal to ISDN Trunk, ISDN Trunk to ISDN Terminal, ISDN Terminal
to Single Line Telephone, ISDN Terminal to Multiline Terminal, and ISDN Terminal to PS
connections are available.
