    The cable connections between the MUX and the TSW are shown in Figure 2-39. As seen in this illustration,
    the cable connected to the front of the MUX leads to the “MUX###” connector on the Back Wired Board (BWB)
    of the TSWM. See the NEAX2400 IMX Installation Manual for more details.

    1. General Function
    This circuit card simultaneously provides all the Attendant Consoles (ATTs) in the system (except the 1-
    IMG system) with information such as the termination/answer/release (abandoned) information of ATT
    calls, or the station idle/busy information through the TSW system link.

    Note:
    MG = 01/03/05/07, Unit = 2, Group = 25, Level = 6-7 are used to input the information into TSW by the
    DLKC.

    Emergency Alarm Controller
    1. General Function
    The PH-PC40 (EMA) circuit card detects various kinds of alarms which might occur in the system, and
    sends out information about the detected alarm to the circuits concerned. This circuit card can activate the
    system MJ/MN LEDs on the TOPU. Additionally, this card can control the active/stand-by status of the
    CPU in the case of dual configuration. For the 1 IMG system, this circuit card has the Music-On-Hold
    sending function.
