3.3.2 Three-to-Three Cables

To associate the MDF wire pairs and the MC modem ports, the three-to-three cable remaps the wire pairs from the MC connectors to the MDF connectors. Use the cable in systems with dual-port DMT-2 ATU-C or quad-port xTU-C modules installed in the MC. Table 3-7 lists the backplane connectors and the part numbers for the three-to-three cables connecting the MC to the MDF in a Direct Connect without a PSC configuration.
