ARRIS introduced a new module that significantly increases the downstream density of its DOCSIS 3.0 C4 CMTS. The module will provide higher speed service tiers, especially for eight channel bonded services — enabling speeds up to 304 Mbps for North American DOCSIS (Annex B) and 400 Mbps for European DOCSIS (Annex A). 
DOCSIS 3.0 was initially introduced in 2008 on the C4 CMTS with a 16 downstream channel single slot Cable Access Module (CAM). With this second generation DOCSIS 3.0 capability, the capacity of the 16D CAMs can be increased to 32 Annex B or 24 Annex A downstream channels.
ARRIS is also announcing C4 software release 7.4, which provides IPv6 support as well as support for DOCSIS 3.0 Multicast traffic. All these new features build on the highly reliable C4 architecture with its industry-leading redundancy.
