<p>A cable interface system for a high availability, high frequency cable network. An example embodiment includes a Radio Frequency Matrix Switch (10) which connects N cable head ends with N + 1 Cable Modem Termination Systems (14) by a set of coaxial cables (12) 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 (24, 26) 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.</p> |
