This standard provides network-to-customer installation (CI) interface requirements for the connection of a Public Safety Answering Point (PSAP) CI to a network providing access to an Enhanced 911 switching system. The inter-face uses loop reverse-battery signaling with a CI-provided battery source. The inter-face allows users of the En-hanced 911 system to communicate with the PSAP CI and allows the Enhanced 911 system to transmit the caller’s emergency service identification (CESID) information to the PSAP CI.
