Power Switch
1. General Function
This circuit card is a power supply card that supplies DC -48 V operating power to the circuit cards mounted
in the TSWM.  It also provides the DC-DC converter function which generates output power DC +5 V, -5
V, and +12 V to MISC slots.
The two PWR SWs cards make the power supply redundant.

PH-SW10
Time Division Switch
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 IMX
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.

Figure 2-48 shows the clock signal routing around the Phase Locked Oscillator (PLO).
Figure 2-48   PLO Function Diagram
When the system operates as the clock source office of the digital network, the OSC (PA-CK14) card is required,
and the OSC supplies the high-precision clock signals (±0.3ppm deviation) for the base clock of the PLO. When
the system operates as the clock subordinate office, the TSW internal oscillator (±5ppm...

Time Division Switch
The PLO can output the clock signals (CLK) and the frame head signals (FH) as follows:
32.768MHz CLK
8KHz FH
5 msec × “n” FH (for wireless module).
The MUX performs multiplexing/de-multiplexing of the 2 Mbps PCM highways running in PIM 0, and it
sends/receives the PCM to/from the TSW, and operates like the MUX card of PIM 1/2/3. 
This circuit card includes the Digital Tone Generator (DTG) and hold tone (MUSIC) insertion circuit....
