INTRODUCTION
The figure below shows an example of the system configuration of NEAX2400 IPX.
PHA : Handles control signals sent to/from an analog terminal connected to Analog Media Con-
verter.
PHD : Handles control signals sent to/from IP terminals such as DtermIP INASET and Dterm SP20.
PHC : Sends/receives CCIS control signal from/to IP network.
IP PAD : Provides interface function between terminals/devices on LAN and conventional network
such as PSTN, ISDN, and private network.
