Stephen is dead on here. In DOCSIS the downstream communication happens in
one or more normal cable TV channel band, ie 6MHz channels from 54 MHz to
890MHz. The upstreams will be (in most cases) either 1.6 MHz, 3.2 MHz, or
6.4MHz wide and in the 5-42 MHz range.

for a whole host of reasons unrelated to NAT, so
that's a fine red herring you've also brought up.
No, it's not. SBCs can and do a lot more than NAT transversal, but the
reasons that SIP operators of any scale can't live without them is NAT.
