Abstract
Network terminations are made available to a customer and installed by a network operator of a digital communications network. The customer is responsible for the supply of power to the network terminations. In the event of a power failure, a network termination of the digital communications network sends an error message (FM) to the customer who is responsible for correcting the power failure. The error message (FM) is sent in the payload of the digital message signals. The network termination (NT) includes a power supply (USV) which in the event of the power failure can sustain output for a predetermined period of time, in which the error can be signaled. To signal the error, the payload may be overwritten with a predetermined bit pattern (BM).
