    ABSTRACT: This document is a complete guide to Local Exchange Carrier (LEC) Operator Services. The term Operator Services refers to a broad
    range of fully and partially automated, and manual, assistance and information services. For example, Operator Services include
    directory assistance services typically accessed by dialing 411 or 555-1212, 0- assistance services, 0+ alternately billed and handled
    services, coin services, and intercept services. Two popular Operator Services include directory assistance and calling card billing.

    Telcordia Notes on Operator Services is a first of its kind for this industry, defining the wide variety of Operator Services
    architectures, capabilities, features, and signaling in one comprehensive document. This Special Report provides a quick reference to
    current and emerging Operator Services technical information for service providers and equipment suppliers involved with the Operator
    Services and directory assistance industries. In addition, the document describes the Operator Services in a simple, high-level
    manner as compared to the more detailed generic requirements that are referenced throughout the Special Report.

    Telcordia Notes on Operator Services describes both the current environment and the anticipated evolution of this industry. The
    current environment overview describes the existing: Operator Services, dialing sequences, architectures, capabilities, signaling,
    billing information, and force measurements. The evolutionary discussion addresses the evolving services and technologies, including
    the latest speech technology advancements as well as enhanced versions of Directory Assistance services.

    Although Operator Services continues to be a traditional voice-based technology industry, some convergence is occurring with other
