Abstract

A serial link interface unit includes serialized data stream interfaces configured to receive a serialized data stream having a data rate and set of timeslots; an aggregate serialized data stream interface configured to communicate an aggregate serialized data stream having aggregate data rate and plurality of aggregate timeslot sets each coming sequentially in time, wherein a second aggregate timeslot set comes after a first aggregate timeslot set; and wherein the serial link interface unit interleaves data from the different serialized data streams received at the plurality of first interfaces by mapping data from a first timeslot from each different serialized data stream to the first aggregate timeslot set in the aggregate serialized data stream and mapping data from a second timeslot from each different serialized data stream to the second aggregate timeslot set in the aggregate serialized data stream.

First claim

What is claimed is:

1 . A summing unit within a telecommunication system, the summing unit comprising:
at least one port configured to receive first multiplexed digital data from a multiplexing unit, the multiplexed digital data including first digital data from a first device multiplexed with second digital data; and at least one summer function configured to sum the first digital data with other digital data to generate summed digital data for conversion to radio frequency signals and transmission at an antenna.

2 . The summing unit of claim 1 , further comprising:
at least a second port configured to receive the other digital data from another device.

3 . The summing unit of claim 1 , further comprising at least a second port configured to transmit the summed digital data to a remote antenna unit, the remote antenna unit configured to convert at least a portion of the summed digital data into the radio frequency signals within at least one radio frequency band, the remote antenna unit further configured to transmit the radio frequency signals within the at least one radio frequency band from an antenna of a remote unit to at least one subscriber unit.

4 . The summing unit of claim 1 , wherein the second digital data is from a second device.

5 . The summing unit of claim 1 , wherein the multiplexing unit is configured to generate the multiplexed digital data by multiplexing the first digital data from the first device with the second digital data.

6 . The summing unit of claim 1 , wherein an Ethernet switch is positioned within a signal path between the first device and the summing unit.

7 . The summing unit of claim 1 , wherein the summing unit is remotely located from the multiplexing unit.

8 . The summing unit of claim 1 , wherein the telecommunications system is a distributed antenna system.

9 . A method for communication within a telecommunication system, the method comprising:
receiving first multiplexed digital data at a summing unit from a multiplexing unit, the first multiplexed digital data including first digital data from a first device multiplexed with second digital data; and summing the first digital data with other digital data at the summing unit to generate summed digital data for conversion to radio frequency signals and transmission at an antenna.

10 . The method of claim 9 , further comprising:
receiving the other digital data from at the summing unit from another device.

11 . The method of claim 9 , further comprising:
converting at least a portion of the summed digital data into the radio frequency signals within at least one radio frequency band at a remote unit; and transmitting the radio frequency signals within the at least one radio frequency band from an antenna of a remote unit to at least one subscriber unit.

12 . The method of claim 9 , wherein the second digital data is from a second device.

13 . The method of claim 9 , wherein the summing unit is remotely located from the multiplexing unit.
