PH-SW10
Time Division 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.
