Abstract
A bunching block and method of operation is disclosed wherein the bunching block is adapted for use in a public utility central office to interconnect a plurality of user loops in series with a supervisory McCulloh receiver, the bunching block including separate connectors for respective connection in series with the receiver and with the respective user loops, separate switches having a normal operating position for connecting the user loops in series with the receiver, the switches being selectively operable at the public utility central office for facilitating rapid location of a fault in the series interconnected user loops. With a number of bunching blocks being employed in series at different central offices, additional switches are preferably provided which operate similarly for selectively isolating all of the user loops in a respective central office from the series connection with the McCulloh receiver.
