ENTRA

electronic communications hardware and software for the delivery of broadband data and video services over hybrid fiber coaxial cable, passive optical networks, and direct Ethernet, namely, strand, wall, or pedestal mounted access nodes with an integrated bi-directional Ethernet switch used to convert internet protocol signals transported using the Ethernet standard to digital signals over fiber-optic cable using passive optical network standards; strand, wall, or pedestal mounted access nodes with an integrated bi-directional Ethernet switch used to convert internet protocol signals transported using the Ethernet standard to digital signals over fiber-optic cable or copper cable using Ethernet standards; strand, wall, or pedestal mounted access nodes with an integrated bi-directional Ethernet switch used to convert internet protocol signals transported using the Ethernet standard to quadrature amplitude modulated or orthogonal frequency-division-multiplexed signals that are transported over fiber-optic cable or copper cable using the Data Over Cable Service Interface Specification; indoor rack mounted legacy QAM adapters used to convert quadrature amplitude modulation signals traditionally transported over hybrid fiber-optic coaxial cable to internet protocol signals transported using the Ethernet standard; software used to configure and monitor the aforementioned access nodes and legacy adapters with application program interfaces to support connections with operations support systems and business support systems
