The Motorola kit needs new line cards. The original ones can't do more than 8 channels per MAC domain.
The Cisco and Arris platforms move towards
CCAP.
The SPA installs would be
these 3Gb cards.
You would be using the upstream ports on the card. The downstream dealt with by the SPAs.
Unsure what you are referring to with regard to the rest. The frequencies used are simply working downwards from the existing 323MHz range. Single MAC domain, modems load balanced within that domain.
CMTS load balances within a single MAC domain by changing the MDD modems receive when they come online. With 16 channels simply send some 8 channel modems to the lower 8, some to the upper 8, 16+ channel devices get the whole lot. With 12 channels some get the lower 8, some get the upper 8, and load balancing across the channels takes care of the rest even though 4 of the channels have all modems on them.
