Typical IPE trunk card architecture
The switch communicates with IPE modules over two separate interfaces.
Voice and 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
