ABSTRACT:
In operational environments where local loop generation equipment is used, communication interruptions between a central office and a customer premises device is minimized by using a dedicated communications link between the local loop generation equipment and the central office. A processing mechanism at the central office determines if, when, and under what circumstances the customer premises device will be notified in response to the activation of local loop generation equipment. This eliminates the need to place local loop generation equipment in series with a communications path that runs between the central office and the customer premises. The central office may provide the dedicated communications link in the form of a telephone line which is equipped to place outgoing local calls, but not equipped to receive incoming calls, and not equipped to place long-distance calls.
