Appl. No.:

09/691624

Inventors:

Michael J. Simoes - Fall River MA, US
Stanley Ivas - Mansfield MA, US

International Classification:

H04N007/173

US Classification:

725127, 725111

Abstract:

A cable interface system for a high availability, high frequency cable network. An example embodiment includes a Radio Frequency Matrix Switch which connects N cable head ends with N+1 Cable Modem Termination Systems by a set of coaxial cables having 75 ohm BNC connectors in the forward path and 75 ohm connectors in the return path. Push-on type connectors along with reduced size connectors and cables provide increased access to connection points on interface panels. Angled interface panels on the Radio Frequency Matrix Switch provide increased connector space. Grouping of connection points on a the Radio Frequency Matrix Switch simplifies installation and replacement of cables. The Radio Frequency Matrix Switch can immediately switch a spare Cable Modem Termination System into service as necessary to avoid down time.

Abstract:

A cable management system for electronic patchboard and routing systems. Cables are fabricated in a uniform length with appropriate termination Functional sets of cables are bundled and enclosed in a distinctly identifiable bundling material. Bundles are wrapped around a reel which has features for removable attachment to a cabinet. Reels are removably mounted to the cabinet at locations chosen to facilitate neat cable dressing. Appropriate lengths of cable are unwound from the reel. Cables are connected to associated connection points while leaving excess cable lengths wrapped around the reel.
