Legacy QAM Adapter for DAA

Terrace Logo

The Entra Legacy QAM Adapter (LQA) accepts RF from existing Edge QAM equipment, demodulates the QAM carriers, encapsulates in R-DEPI, RTP or UDP and provides unicast/multicast MPTS over Ethernet to the Access Node for re-modulation to RF. The LQA allows operators to leverage the existing installed edge QAM infrastructure for R-PHY and R-MACPHY deployments. The LQA minimizes new headend equipment, mitigates interoperability risk, and easily supports mixed deployments of centralized and distributed access.
