CHAPTER 2 ND-70182 (E) Page 88 Revision 4.0 PH-PC36 Multiplexer 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.

CHAPTER 2 ND-70182 (E) Page 90 Revision 4.0 PH-PC20 Data Link Controller PH-PC20 Data Link Controller 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. Figure 2-40 Location of PC-PH20 in the System Note: MG = 01/03/05/07, Unit = 2, Group = 25, Level = 6-7 are used to input the information into TSW by the DLKC. 2.

ND-70182 (E) CHAPTER 2 Page 93 Revision 4.0 PH-PC40 Emergency Alarm Controller PH-PC40 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.
