US Patent:

39718913, Jul 27, 1976

Filed:

Mar 14, 1975

Appl. No.:

5/558605

Inventors:

John R. Wolcott - Orlando FL

Assignee:

Martin Marietta Corporation - Rockville MD

International Classification:

H03K 1322
H04J 300
H04L 300
G06F 500

US Classification:

179 15AP

Abstract:

A switching network is disclosed that is capable of handling analog, PCM and CVSD signals connected to said network via loops or trunks. All signals are converted into CVSD format, synchronized to the network clocks, and switching is carried out on a time divided basis by shifting bits from one channel slot in the frame format on the input side of the switching circuit to a different channel slot in the frame format on the output side of the switching circuit. The multiplexing and demultiplexing of data on the input and output sides of the channel shifting mechanism is controlled by words in a random access memory. Thus, the mux-demux operation is easily varied by changing the word storage in the random access memory. The channel shifting is controlled by the words stored in a second random access memory. Thus, channel shifting is also easily varied.

International Classification:

H04W 76/28
H04B 1/401
H04B 5/02
H04W 76/14

Abstract:

Embodiments discussed herein refer to systems, methods, and circuits for establishing EHF contactless communications links. The EHF contactless communication link may serve as an alternative to conventional board-to-board and device-to-device connectors. The link may be a low-latency protocol-transparent communication link capable of supporting a range of data rates. The link may be established through a close proximity coupling between devices, each including at least one EHF communication unit. Each EHF unit involved in establishing an EHF communication link may progress through a series of steps before data can be transferred between the devices. These steps may be controlled by one or more state machines that are being implemented in each EHF communication unit.
