Abstract

The telephone line test capability of a craftsperson'"'"'s test set is supplemented by communication/interface circuitry which carries out data communications with a host central office control processor, and contains memory for storing (task assignment) information downloaded from the central office control processor. This task assignment information stored in the test set-communications unit may be coupled from the unit to an associated printer for providing a hard copy of service assignment information to the field technician. In addition to printing out the downloaded task assignment information, the printer unit contains a charging circuit which charges a rechargeable battery in the handset for powering its internal circuitry. During off-duty hours, the test set may be connected to a home dispatch unit installed in the craftsperson'"'"'s home and through which the handset is coupled to a telephone link for providing off-duty communications with the central office processor without technician intervention. The home dispatch unit also contains a battery charging circuit through which the test set'"'"'s internal battery is charged when the test set is coupled to the dispatch unit and communications between the central office and the test set-communication unit are not taking place.
