    1. General Function
    This circuit card controlled by CPU is used for line test of a subscriber’s line. The circuit card supports to
    send Howler Tone to external test equipment, besides the circuit card can detect or send various tones, and
    send PB (DTMF) signal for automatic trunk test.
    Note:A system cannot send Howler Tone during line test. The number of available lines within the line test/au-
    tomatic trunk test at the same time is only one.

    1. General Function
    The PH-PC36 (MUX) circuit card is an interface card for mounting line circuits and/or trunks. In between
    the CPR and the Port Microprocessor (PM) of the line/trunk circuit, this circuit card provides an interface
    for PM control and management by the CPU. Likewise in between the TSW and the line circuit/trunks, this
    circuit card provides an interface for multiplexing/de-multiplexing of voice Pulse Code Modulation (PCM)
    information and digital data information.

    The PCM highway running is illustrated in the figure below. There are sixteen 2Mbps PCM highways
    (HW0 - HW15) in the PIM. Each PCM highway runs from a card slot to the MUX circuit card. For instance,
    highway number zero (HW0) appears in Slot 04 and also Slot 05, thus the HW0 carries the PCM of the
    Group 0, 1, 2 and 3. 
    Likewise, the HW6, 7, 14, 15 cover the Groups 24 through 31. However, the time slots of Groups 24 and
    25 are exclusively used for the Speech Path Memory (SPM).
    All highways in the PIM lead to a MUX card, so 512 time slots (32 time slots per highway × 16 highways
    = 512 time slots) of PCM are multiplexed/de-multiplexed at a MUX and sent/received to/from the TSW
    circuit card across the 32.786Mbps of the Low Voltage Differential Signaling (LVDS).
    Also the MUX card provides the PM bus interface. The CPR controls and administrates the PM of the line/
    trunk circuit card via the TSW and the MUX.
    In addition, this circuit card supports 3-Party Conference (CFT) function and is equipped with eight circuits
    of 3-Party Conference. The CFT appear in time Slots 8 through 31 of the HW13 (Group 21 - 23).
