The Upstream Cable Access Module 2 (UCAM-2) is the second generation line card for the E6000 CER that provides upstream RF functionality. The UCAM-2 is designed to deliver hardware support for both SC-QAMs (i.e. DOCSIS 3.0) and OFDMA (i.e. DOCSIS 3.1) on a per-connector basis. From a hardware perspective, the UCAM-2 is capable of supporting an average of 12 SC-QAMs plus two blocks of 96 MHz OFDMA on each physical port. Migration to UCAM-2 for the existing E6000 deployed base is very simple. UCAM-2 utilizes the same Upstream Physical Interface Card (UPIC) as the Gen 1 UCAM, so no disconnecting of RF cables is required during the upgrade activity.
