BRI Features

By using Basic Rate Interface (BRI) lines, the MERLIN LEGEND system can use
features offered by the 5ESS central office. The BRI features described below
are supported by the MERLIN LEGEND system. The Multi-Level Precedence and
Preemption (MLPP) feature can be used only on a private configured network
and, therefore, is used primarily by the Federal Government.
NOTE:
All BRI features are ordered from the central office (CO) at the time of
subscription for BRI lines. Depending on the CO, the features may be available
under a different name and voice prompts may vary.
All-Call Privacy/Per-Call Privacy
The All-Call Privacy feature prevents or allows the Calling Party Number/Billing
Number (CPN/BN) to be sent by the central office when an outgoing call is made
on a BRI line. If All-Call Privacy is activated for that line, the CPN/BN is not sent.
If All-Call Privacy is not activated, the CPN/BN is sent.
Per-Call Privacy overrides the All-Call Privacy status for the next call only. For
example, if Per-Call Privacy is used on a line that has All-Call Privacy activated
(preventing a number being sent), the number is sent for the next call only.
Calling Party Number/Billing Number
The Calling Party Number/Billing Number (CPN/BN) feature provides incoming
calling party number information that identifies the originator of a call in the call-
handling displays of MLX telephones. If the MERLIN LEGEND system
subscribes to this BRI feature, each incoming call to the system over a BRI line
can be accompanied either by the calling party number or by the billing number
of the calling party supplied by the network. The billing number is the telephone
billing number for the department or company.
Preference for a calling party number or a billing number can be specified
during subscription to the BRI features.
NOTE:
If the calling party subscribes to the 5ESS feature All-Call Privacy, no number is
received.
