ADTRAN 1430017L2D4D1DK3D4OCU OCU Channel Unit DA Port

ADTRAN 1430017L2D4D1DK3D4OCU OCU Channel Unit DA Port is a D4 Office Channel Unit module that provides a dedicated Data Port (DA) interface for data transmission within legacy carrier networks. This OCU Channel Unit is designed to be installed in ADTRAN Total Access equipment that accepts D4 OCUs, enabling a data-path connection across the channel bank for digital data services. The DA Port designation indicates a Dataport interface used for interfacing data traffic with the OCU channel unit, supporting the all-rate data path configurations characteristic of D4-OCU deployments. The specific part number 1430017L2D4D1DK3D4OCU identifies this exact OCU/DA-port configuration, ensuring compatibility with a range of D4 OCUs and their supporting chassis within the Total Access family. Typical applications include terminating and routing data signals within legacy DDS/D4-based networks, where a dedicated channel-unit datapath is required for reliable data service delivery.
