Scalability
ARRIS offers a number of combinations of downstream to upstream channel ratios to improve scalability. With the ability
to accommodate many configurations, the C4 CMTS can grow to meet evolving subscriber traffic considerations along with
reducing inter-shelf cabling. This leads to lower cost for installation, operations, and maintenance.
