    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.

    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.

    Time Division Switch
    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 deviation) can be the
    base clock of the PLO. The source clock of the subordinate office is either the digital clock supply (DCS) or the
    digital interface clock (DIU0 - DIU3). When the clock source failure has occurred, the PLO chooses another
    clock source automatically in the order of:
    1DCS0

    3. DIU0

    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. The
    TONE ROM located on this circuit card contains the audible tone, and the hold tone is supplied from the
    EMA card. In addition, the designated time slot of PCM (Speech Path Memory: SPM) can be inserted as a
    tone/music voice prompt. (For example, you can join the SPM and a DAT port by the nailed down
    connection, and the DATs voice prompt is given to the system instead of ordinary tone/music.)
    Additionally, this circuit card supports the CFT (3-Party Conference) function and is equipped with eight
    (8) circuits of 3-Party Conference Trunk.
