Abstract
In signal-splitting equipment for multiple subscribers, circuitry is disposed on a signal-splitter card which connects with a back plane providing physical support and electrical connection to other splitter cards and to distant sites, as well as to an interface with a system conducting automatic testing of DSL circuits. Each splitter card also carries a separate relay card with signal-routing relay circuitry, the relay card being affixed by means of a switching connector having bypass circuitry which ensures normal communication of DSL signals and audio signals in the event that a relay card is disconnected from its signal-splitter card. During a testing of the equipment, the system operates the relays of the relay cards of the respective signal-splitter cards for a connection of test equipment to various equipment associated with a specific subscriber.
