Abstract: A system and method for permitting a customer of a telecommunication company, for whom fiber to the premises (FTTP) has been installed, to continue to use the telephone during utility company power failure, by powering both the optical network terminal (ONT) and the customer's telephone(s).

Abstract: A method for generating reliability tests for a telephone system is based upon sampling an orthogonal array which covers various combinations of test parameters. Field data is collected of actual telephone activity on a telephone system. The field data is evaluated so as to determine call-mix characteristics.

These test case scenarios are used to run tests on the telephone system. These tests are preferably performed using automated test scripts. After the test data is collected, reliability metrics are calculated from the test data.
