Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE         A switching system is disclosed in which a plurality of incoming highways are multiplexed in time division cells that have arrived are written into a buffer memory, the cells thus written are read in an appropriate order, separated in a multiplex way and distributed among a plurality of outgoing highways thereby to perform an exchange operation.  An FIFO (First In First Out) buffer stores an empty address of the buffer memory.  The address in busy state is controlled in a manner corresponding to the outgoing highways.  When a cell is written in the buffer memory, the empty address is taken out of the data output of the FIFO buffer.  When the cell is read of the buffer memory the address already read is returned to the data input of the FIFO buffer by an idle address chain.

Title: Jackfield with split-front panel
Inventor: LAU FREDERICK L
IPC: H01R24/58
Filed: 1988-10-03
Granted: 1992-04-14
Abstract: Abstract of the Disclosure A jackfield with a split front panel so that it can be removed to provide access to jack modules without breaking patch cord interconnections between jacks.  Each jack module includes a printed circuit board having a lamp assembly and a tri-jack connected to the front and extending forwardly.          The printed circuit boards are hard wired at the back of the jackfield and the printed circuit boards route the circuits to the tri-jack and the lamp assembly.  To remove just a tri-jack, it is pulled forwardly after the split front panel is removed.  A lateral bracket retains the printed circuit board to prevent it from being pulled forwardly.  To remove the entire jack module, the wire wraps are disconnected from the back of the printed circuit board and the retaining bracket is removed.  Then, the entire module can be slid forwardly in its guide slot.  When a module is inserted, conductor pads on the printed circuit board automatically align and electrically mate with slidably engageable bus terminals to provide -48 volts DC and ground for lighting the lamp.
