Abstract
Abstract A method and portable panel structure for carrying out the method serve to restore rapidly telephone service to customers after a telephone cable connecting the customers'' lines to a central office has been inadvertently severed. Arbitrary connections from the severed portion of the cable extending from the central office are made to central office jacks in the panel and arbitrary connections from the severed cable portion extending from the customer''s premises are connected to customer jacks on the panel. A tester''s plug or answer cord together with a voltage source, ringing generator, and test unit are provided in the panel and enable a tester to identify a customer''s telephone number and patch the same with one of several patch cords to the proper central office jack thereby immediately restoring service.
