Abstract
A copper wire pair linking network terminating equipment in a home with a relatively localized multiplexer, e.g., in a street cabinet, carring high data rate, e.g., VDSL, signals such as ATM and ISDN, combined at the multiplexer. It is necessary for the multiplexer to be provided with a power supply but, in the event of failure of the power supply, VDSL signals could not be generated in the multiplexer. To provide some fall-back in such a case, a metal link from the local exchange to the network terminating equipment is formed, for example, by using relays, thereby permitting ISDN signals to be received in the home even though the higher data rate ATM has now failed.
