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.
