ISDN Calling Line Identification Enhancement
The ISDN Calling Line Identification Enhancement allows the choice of
National and Local prefixes. This is applicable to connected numbers
received from a ISDN BRI terminal and sent over a ISDN trunk.
EuroISDN Continuation
The EuroISDN Continuation capability adds National and Local prefixes to
the connected number being sent. This is programmed on a route basis and is
applicable to connected numbers received from a ISDN BRI terminal and sent
over a ISDN trunk.
DPNSS/DASS2
The mapping of the connected number information element in a connect
message from or to a ISDN BRI terminal and the connected line identification
in a CRM message from or to a DPNSS or DASS2 interface is supported.
Feature packaging
ISDN Basic Rate Interface Connected Line Presentation/Restriction requires
the following packages:
— Basic Rate Interface Line Application (BRIL) package 235,
— Basic Rate Interface (BRI) package 216, and
— Extended Peripheral Equipment (XPE) package 203.
Feature operation
Connected Line Identification Presentation (COLP)
The number dialed and the connected number may not be the same due to call
diversion.
The COLP service is disregarded if the connected party's ISDN BRI terminal
has COLR enabled to 'presentation restricted'. As an example, assume that
Set A, the calling party, has connected line presentation enabled (COLP =
YES) and calls Set B. Set B has enabled 'presentation restricted'. Set A's
request for connected line presentation is denied. In situations where the
calling party has configured COLP = YES and the connected party has
requested 'presentation restricted', the connected party's restriction request
prevails.
