Abstract
A method and apparatus for aligning a digital communication data stream across a cell network, wherein plurality of timeslot samples are generated by sampling the digital communication data stream transferred over a first circuit-switching communication link. The timeslot samples are assembled into a series of communication cells in a bit or byte skewed arrangement. An align flag in the header of a communication cell indicates that the communication cell contains an aligned timeslot sample.

A method for aligning a digital communication data stream across a cell network, comprising the steps of:
- generating a plurality of samples by sampling the digital communication data stream on a first circuit-switching communication link;
- assembling the samples into at least one communication cell, and setting an align flag in the communication cell if the communication cell contains an aligned sample;
- transferring the communication cell over a cell network according to a packet-switching communication protocol;
- sampling the communication cell over the cell network, and disassembling the communication cell;
- aligning the samples on a second circuit-switching communication link if the align flag is set, and transferring the samples over the second circuit-switching communication link.
An apparatus for aligning a digital communication data stream across a cell network, comprising:
- means for generating a plurality of samples by sampling the digital communication data stream on a first circuit-switching communication link;
- means for assembling the samples into at least one communication cell, and setting an align flag in the communication cell if the communication cell contains an aligned sample;
- means for transferring the communication cell over a cell network according to a packet-switching communication protocol;
- means for sampling the communication cell over the cell network, and disassembling the communication cell;
- means for aligning the samples on a second circuit-switching communication link if the align flag is set, and transferring the samples over the second circuit-switching communication link.
