Claims
- 1. An apparatus for coupling a first plurality of channels received over a first telecommunications line to a pair of lower capacity telecommunications lines, in which a total capacity of the pair of lower capacity telecommunications lines exceeds the capacity of the first telecommunications line, said apparatus comprising:
- a) a high capacity interface to the first telecommunications line for receiving the first plurality of channels in a first predetermined format;
- b) two low capacity interfaces, one to each of the lower capacity telecommunications lines for outputting a subset of the first plurality of channels to each of the pair of telecommunications lines in a second predetermined format; and
- c) a digital channel interface for receiving a plurality of digital channels, wherein a total number of digital channels is less than or equal to a difference in the total capacity of the pair of lower capacity telecommunications lines and the capacity of the first telecommunications line;
- d) a multiplexer being coupled between the high capacity interface and the two low capacity interfaces and selectively assigning channels from the first plurality of channels and the plurality of digital channels to each of the low capacity interfaces; and
- e) an inverse multiplexer being coupled between the high capacity interface and the two low capacity interfaces and demultiplexing a plurality of digital channels received from the two low capacity interfaces and forming a plurality of channels from any remaining channels and outputting them to the high capacity interface.
