Unparalleled Compact CMTS Value and Performance


With the ARRIS C4c compact-chassis CMTS, operators cost-effectively deploy full-featured DOCSIS 3.0-based services into space-constrained head-ends and small -to -medium-size systems. The C4c CMTS is also an ideal choice for MSOs rolling out services incrementally, where the capacity and cost of a full-scale CMTS is not required. For rapid deployment, scalability, and flexible management of DOCSIS 3.0 functions, no competitor’s compact-chassis CMTS can match the C4c CMTS. C4c solutions scale robustly to 10,000 subscriber devices and efficiently support a wide variety of popular and emerging voice and data services. Operators can quickly and profitably respond to subscriber and corporate demand for DOCSIS 3.0 value-added services, IPTV, emerging convergent services, and higher data speeds services that command premium prices and satisfy top-tier customers. Based upon industry-leading ARRIS engineering, the C4c CMTS delivers high port densities, low power consumption, and a small footprint. C4c solutions reduce CAPEX and OPEX through extended head-end life, reduced power and cooling requirements, improved network performance, enhanced reliability, and expanded capacity. The C4c CMTS uses the same software and RF and routing blades of the industry-leading ARRIS C4 CMTS and offers the same superb manageability, capability, and customer-pleasing quality of service.
