摘要:
A telecommunications apparatus includes a switching matrix. The telecommunications apparatus also includes a plurality of conductive user output locations and a plurality of conductive network input locations. For any given user output location there exists a conductive path coupling the given user output location to a corresponding network input location. The telecommunications apparatus also includes a plurality of switches. For any given conductive path, a switch is interposed therein, and each switch has a first state in which the given conductive path is unaltered, and a second state in which the given conductive path is altered, so that the given conductive path couples the corresponding user output location to the switching matrix. The aforementioned telecommunications apparatus may be networked with other such telecommunications apparatuses.

A telecommunications system includes a switching matrix having a plurality of conductive switching matrix input locations, a plurality of conductive switching matrix output locations, and a plurality of conductive paths and switches interposed between the switching matrix input and output locations so that any given switching matrix output location may be electrically coupled to any given switching matrix input location. The telecommunications apparatus also includes a cut-over matrix electrically coupled to a first subset of the switching matrix output locations. A cross-connect distribution unit (CDU) is electrically coupled to a second subset of the switching matrix output locations.

Clock Priority Chain Level Systems and Methods are provided. In one embodiment, a method for determining clock priority for a multihost unit distributed antenna system is provided. The method comprises identifying which port of a plurality of ports is receiving a reference clock signal having a highest priority Network Chain Level (NCL) value, wherein the highest priority NCL value indicates a master clock priority level (MCPL) of a host unit providing a Master Clock and a chain level value indicating a chain depth; selecting a system clock reference port from the plurality of ports based on the highest priority NCL value; locking a local clock to a reference clock signal received on the selected system clock reference port; calculating an incremented NCL value based on the highest priority NCL value; and transmitting the incremented NCL value over the plurality of ports.
