ISDN Basic Rate Interface Connected Line Presentation/Restriction is a
supplementary service that enables the Meridian 1 to either allow or restrict
the presentation of a connected party's ISDN number and sub-address on the
display of an ISDN BRI terminal. The presentation of a ISDN number and
sub-address to the calling party occurs when the connected party's ISDN BRI
terminal answers the call. In addition to the BRI terminal, this service can be
applied to Meridian 1 proprietary and Analog (500/2500 type) sets.
The Connected Line Presentation (COLP) service applies to the calling party.
COLP allows the presentation of the connected party's ISDN number and
sub-address to the calling party.
The Connected Line Restriction (COLR) service applies to the connected
party. COLR restricts the presentation of the connected party's ISDN number
and sub-address to the calling party. COLR is activated on the ISDN BRI
terminal of the connected party.
The connected party's identification is only provided to the calling party, if
the ISDN BRI terminal of the connected party supports this feature.
When COLP/COLR feature is activated, the system monitors the
configuration of the terminal service profiles on the calling and connected
parties ISDN BRI terminals. Depending on this configuration, the system
determines whether or not information is allowed or restricted to the calling
party.
Operating parameters
Through configuration, the Meridian 1 BRI terminal interface controls the
provisioning of the connected party's information on the interface (COLP
prompt). This avoids sending COLP when the terminal does not support this
supplementary information.
With the presentation restricted option activated, some BRI terminals may
not have the capability to restrict the presentation of digits from the connected
party. The Meridian 1 BRI terminal interface has the capability to restrict
sending the connected party information the calling party if COLR is
activated (COLP prompt).
