Configuring The Downstream Interleave Depth - Motorola BSR 2000 Configuration And Management Manual

Release 1.0

Configuring the Downstream Interleave Depth

The cable operator can protect the downstream path from excess noise or decrease
latency on the downstream path by setting the interleave depth. A higher interleave
depth provides more protection from noise on the HFC network, but increases
downstream latency. A lower interleave depth decreases downstream latency, but
provides less protection from noise on the HFC network.

Note: The Euro DOCSIS standard requires an interleave depth of 12, 12
Taps, and 17 increments.
