ARRIS is displaying its new C4 CMTS 24U Cable Access Module (CAM) at the Cable Show in Chicago. The 24U CAM doubles the C4 CMTS' previous upstream density. The 24U CAM supports DOCSIS 3.0 upstream channel bonding and from 5-42, to 5-65 and 5-85 MHz for upstream services. The 24U CAM is fully supported using today's high-performance C4 control complex and other chassis components, offering investment protection for all C4 CMTS customers.With the 24U CAM, ARRIS continues providing 'hitless' RF sparing fully integrated into the C4 chassis precluding the need for external wiring or added components. Coupled with the recently introduced XD CAM double density downstream module, the C4 CMTS now delivers true high-availability with density equal to or greater than any competitive CMTS offering available, and total cost of ownership equal to or lower than other competitive solutions.
