Technology
Data over Cable Service Interface Specifications (aka DOCSIS) 3.0 is standard technology certified by Cable labs. The
DOCSIS 3.0 (Annex B) standard provides 42 Mbit/s per channel (theoretically) and 37 Mpbs (practically) downstream per channel. Downstream can bond up to eight channels, which increases the downstream throughput up to (37 × 8) and 27 Mbit/s upstream bandwidth per channel. This is the standard cable modem protocol established by MCNS for
