1 Introduction This supplement to American National Standard for Telecommunications T1 .641-1995 (R2000), Calling Name Identification Presentation, addresses certain regulatory requirements’ that may exist regarding Caller ldentification services. Such regulations may require the service provider to conceal the name of a caller when the calling party number is to be concealed.

An update to some references is also included.
2 Changes to T1.641-1995 (R2000)
2.1 Add the following references to clause 2 (Normative references): T1.625-1993 (R 1999), Integrated services digital network (ISDN) – Calling line presentation and restriction supplementary services.

2 2.2 Replace clause
4.1 with the following:
4.1 Description The Calling Name ldentification Presentation service provides Name Information or Redirecting Name Information to the called party. The storage and delivery of the calling party name are network functions. The calling party takes no actions to activate, initiate, or in any manner provide Calling Name Identification Presentation. The called party, when subscribed to Calling Name Identification Presentation, automatically receives the Name Information. Delivery of a Calling Name may be affected by a subscriber of the Calling Name Identification Restriction service. For example, a subscriber of Calling Narne Identification Restriction who forces the Calling Name “private” when initiating a call would cause an indication of “private” to be delivered to a Calling Name Identification Presentation subscriber. Certain regulatory jurisdictions may require the service provider to inhibit the delivery of the caller’s name when Calling Line ldentification Restriction (CLIR) applies to a call. In such cases, the Calling Name ldentification Presentation subscriber will receive an indication of “private” instead of the caller’s name.
