The purpose of this standard is to enable a wireline exchange carrier (EC) entity and an interexchange carrier (IC), international carrier (INC), or consolidated carrier entity to provide interconnecting equipment that operates compatibly. This standard gives individual-channel signaling protocol requirements for the interface located between a public-switched EC network within an access area and an IC, INC, or consolidated carrier network. The characteristics of the interface are (1) the connection between the first EC and IC switching systems interconnected at the interface is on a trunk-signaling basis, (2) the calling user provides the carrier access code (either explicitly or implicitly) and, in most cases, the called-line identification in one, noninteractive, dialing sequence, and (3) the EC sends the calling- and called-line information when required to the IC, INC, or consolidated carrier at the times and in the order specified by the signaling protocols given in this standard.
