Abstract:
1. A method for interleaving a plurality of data frames for transmission via a plurality of modems in a modem pool, where each of said data frames includes a plurality of code words having a predefined level of error corrections the method comprising: assigning said plurality of data frames to a corresponding plurality of modem time frames, wherein a plurality of code word symbols in each of said data frames is assigned to a plurality of time slots in said modems in said corresponding time frames such that said predefined level of error correction is sufficient to correct error or loss caused to any of said symbols given a predefined level of modem loss or malfunction; and moving any of said code word symbols assigned to one of said time frames to another of said time frames such that said predefined level of error correction is sufficient to correct error or loss caused to any of said symbols given a predefined level of cross-modem error burst while preserving said predefined level of error correction sufficient to correct error or loss caused to any of said symbols given said predefined level of modem loss or malfunction.
