PH-SW10

Time Divisio n Switch
1. General Function

This circuit card combines the Time Division Switch (TSW) with INT, PLO, MUX, and CFT.

The TSW capacity is 2048×2048 time slots, and it allows non-block switching for the maximum IPX

configuration. The INT is an intermediate circuit of the CPR which controls and administrates the Port

Microprocessor (PM) of line/trunk circuit cards via the PM BUS.
