1.General Function

The main functions of the PH-M22 circuit card are as follows:

to collect key setting information on the TOPU of the ISW and send the information to the ISW/the other LNs, depending on the ISEL key setting on the ISW. (for IPX-U system)

to collect various alarm information from all the IMGs/ISW and activate MJ/MN LED on the TOPU display. (for IPX-U system)

to send out the key information to EMA within the same LMG (for IPX-UMG system)

to collect the external MJ/MN alarm information output by EMA in each LMG (for IPX-UMG system)

This circuit card is used for the IPX-U/IPX-UMG system.
