Abstract: A system for transporting data in a Distributed Antenna System (DAS) includes at least one Digital Access Unit (DAU) and a plurality of Digital Remote Units (DRUs) coupled to the at least one DAU. The plurality of DRUs are operable to transport signals between the plurality of DRUs and the at least one DAU. The at least one DAU includes: a data transport coder comprising: a framer, an encoder, a scrambler, and a serializer and a data transport decoder comprising: a deserializer, a decoder, a descrambler, a frame synchronizer, and a deframer.

Abstract: A system for routing signals in a Distributed Antenna System includes a plurality of Digital Access Units (DAUs) and a plurality of Digital Remote Units (DRUs). The plurality of DAUs are coupled and operable to route signals between the plurality of DAUs. The plurality of DRUs are coupled to the plurality of DAUs and operable to transport signals between DRUs and DAUs. The system also includes a plurality of Base Transceiver Stations (BTS) and a plurality of Base Transceiver Station sector RF connections coupled to the plurality of DAUs and operable to route signals between the plurality of DAUs and the plurality of Base Transceiver Stations sector RF port connections. The system further includes one or more delay compensation merge units operable to delay signals transmitted from or received by each of the plurality of DRUs.
