Typical IPE analog line card architecture
DS-30X loops The line interfaces provided by the line cards connect
to conventional 2-wire (tip and ring) line facilities. IPE analog line cards
convert the incoming analog voice and signaling information to digital form
and route it to the Call Server over DS-30X network loops. Conversely,
digital voice and signaling information from the Call Server is sent over
DS-30X network loops to the analog line cards where it is converted to
analog form and applied to the line facility.
