Contains Bellcore's proposed generic requirements for User-to-User Signalling (UUS) in an Integrated Services Digital Network (ISDN). UUS Signalling with Call Control (UUSCC) is a service that allows user equipment to exchange user information in the Call Request phase, Call Confirmation phase, and or Call Clearing phase of a call. This feature is applicable for point to point, on demand, circuit switched, and packet-mode calls. Issue 1, Bulletin 1: This bulletin announces the intention of Telcordia to revise the generic requirements in the document for the interswitch indication that UUS information has been discarded by the network. Issue 1, Supplement 1: This supplement provides supplemental information necessary to obtain compatible ISDN.
