Abstract
In locating a faulty regenerator, a fault locating filter is used in a T1 or T1C Carrier Repeater Apparatus Case or Office Repeater Bay (ORB) to select the appropriate fault locate sinusoid from the output winding of the repeater. This process uses three different filter types at twelve different frequencies. Conventional filter design requires a different filter for each frequency leading to the need to stock 36 different filters. This patent covers the design of a filter which may be optioned to provide all three types and twelve frequencies within a single unit, reducing the required inventory of such filters by a substantial amount.
