    ABSTRACT: GR-506 provides criteria for the direct current (dc) signals and basic alternating current (ac) signals that a Stored Program Control
    System (SPCS) applies to analog interfaces. This document only provides criteria for the basic analog interface signals.

      • Session Information Tones

      • Coin Control Signals

      • Ringback

      • DTMF Signals

      • Coin Deposit Tones

    • Describes an NGN architecture based on ATIS standards.
