Figure 11: 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 or trunk.
Some examples of signaling commands are as follows:
• off hook/on hook
• ringing signal on/off
• message waiting lamp on/off
Maintenance data is data relating to the configuration and operation of the IPE card, and is
carried on the card LAN link. Some examples of maintenance data are as follows:
• polling
• reporting of self-test status
