Adtran Total Access 1000 TDM Commons

The Total Access 1000 commons elements in the TDM configuration comprise what is essentially the main architecture of the TDM configuration. The Total Access 1000 Remote Terminal system is comprised of an outside plant (OSP) housing, HDSL Line Interface Unit (HLIU), Power Supply Unit/Ring Generator (PSU/RGU), Bank Controller Unit (BCU), and POTS or ISDN access modules.

The OSP housing contains all external terminations including the HDSL interface, auxiliary powering interface, bypass pair termination, subscriber loop termination, and grounding terminations. The OSP housing also provides surge protection for the network and subscriber interfaces. The network and subscriber interface terminations are insulation displacement type.
