BIBLIOGRAPHY Abstract
Defines the embedded MTA (E-MTA) requirements for the analogue interface and for powering of the E-MTA. It defines a set of requirements that will enable a service that is sufficiently reliable to meet a consumer expectation of essentially constant availability, including, availability during power failure at the customer's premises, and (assuming the service is used to connect to the PSTN), access to emergency services.
