Release 1.0 CMTS Commands

interleaver-depth

The interleaver-depthcommand specifies the interleaver depth for an ATDMA or MTDMA channel. This command sets the interleaver minimum latency. A higher interleaver depth provides more protection from bursts errors by spreading out the bits for each codeword over a greater transmission time. However, a higher depth also increases downstream latency, which may slow TCP/IP throughput for some configurations.

DOCSIS 2.0 specifies five different interleaver depths - 128:1 is the highest amount of interleaving and 8:16 is the lowest.

■

128:1 indicates that 128 codewords made up of 128 symbols each will be intermixed on a 1 for 1 basis

8:16 indicates that 16 symbols will be kept in a row per codeword and intermixed with 16 symbols from 7 other codewords.
