|Publication Date:||1 September 2008|
This standard defines the interworking relationship between the D-channel layer-3 functions and protocol employed across an ISDN User-Network Interface and an interface using the Session Initiation Protocol (SIP) augmented by the Narrowband Signaling Syntax (NSS) with ANSI Extensions.
This standard defines how the ISDN User-Network Interface and SIP/NSS protocols should be used in combination with call control functions to support the ANSI narrowband services
