The ADTRAN Total Access DS0 Dataport is a single port access module used in the TA 750, 850 or 1500 platforms. It serves as an interface to the basic DDS DSO (64kbps) signal to a T-carrier line. The DSO DP is generally located in either a hub or intermediate office. It is used in conjunction with an ADTRAN All-Rate Office Channel Unit (OCU) dataport or Total Reach DDS dataport located at the end office to extend the DDS network to an end office which has exclusively-served voice channels.

In the receive direction, the DS0 DP converts 2.4, 4.8, 9.6, 19.2, and 56kbps PCM data from the Bank Controller Unit (BCU) at the 64kbps rate to DDS-formatted 64kbps signals for transmission. In the transmit direction, it converts the DDS-formatted 64kbps line signals to 2.4, 4.8, 9.6, 19.2, and 56kbps PCM data at the 64kbps rate for handoff to the BCU. Provisioning is accomplished by utilizing the craft interface on the BCU or SCU, or by selecting the appropriate options using dip switches. Subrate error correction, Zero Code Suppression, and latching loopback are all available. The DS0 DP can also be optioned to operate as a Clear Channel Unit (CCU). Remote latching loopback is activated using the automated testing capability of the Service Test Center (STC) or the faceplate test connector(s) with the portable TPI 108/109 or equivalent DS0 test set.
