ABSTRACT:
A remotely controlled cross-connection switching matrix, particularly suited for telephone systems, has a jumper pin picker and placement mechanism selectively movable along each of three axes under the control of a single drive motor translating a single drive cable over a series of pulleys. Movement along the selected axis is effected by braking movement along the other two axes. The system provides a "soft dial tone" to prospective telephone subscribers' premises having cable pairs permanently connected to the matrix. The cable pair for the calling prospective subscriber is automatically identified at the matrix in response to an off-hook status for that prospective subscriber, and the cable pair identification data is automatically transmitted to the telephone business office. Stored information at the business office for the premises of the identified cable pair is automatically displayed for the telephone company representative responding to a request for service by the calling prospective subscriber. The matrix also permits remote selective connection of unused telephone lines to a test bus connected between the matrix and the central office, thereby permitting automatic, remotely controlled testing of those lines. Improved security of the facility containing the matrix is provided by a feature permitting remote control over the facility door lock.
