Interface Between Carriers and Customer Installations - Analog Voicegrade Enhanced 911 Switched Access Using Network Provided Reverse-Battery Signaling

This standard provides interface requirements for the interconnection of Customer Installations (Cls), such as Private Branch Exchanges, to Enhanced 911 systems. The interface allows the CI to transmit the caller's emergency service identification information to an Enhanced 911 system in applications where multiple terminals share Enhanced 911 switched access. These requirements are intended to assist carriers, end-users, and manufacturers.
