Two-to-One Cables
You can use two-to-one cables to connect one MC to two PSCs for systems using dual-port or
quad-port ATU-C modules. Quad-port ATU-C modules will be available in a future release.
Table 3-3 lists the backplane connectors and the part numbers for the two-to-one cables connecting
one MC to two PSCs in a Direct Connect with a PSC configuration. In this configuration,
64 POTS splitter ports are used in each PSC, for a total of 128 ports.
Note When you use thetwo-to-one cable, see Table C-2 on page C-4 for portmapping information.
Figure 3-3 shows the two-to-one cable.

Tips If you use 64 POTS splitter ports, tie wrap the PSC 2 connector to the rack. When you expand
your system to 128 POTS splitter ports, the PSC 2 connector will attach to a second PSC.
