Typical IPE trunk cardarchitecture
The switch communicates with IPE modules over two separate interfaces.
Voiceand signaling data are sent and received over DS-30X loops and
maintenance data is sent over a separate asynchronous communication
link called the card LAN link.
Signaling data is information directly related to the operation of the
telephone line. Some examples of signaling commands are as follows:
•off hook/on hook
•ringing signal on/off
•message waiting lamp on/off
