2.4 System Overview
The IES chassis, cards, and modules function together as follows:
• The management card transmits services upstream, receives downstream traffic into the IES,
and manages the system.
• Different management cards provide different upstream ports.
• The output power to the backplane which transmits the power to the fan module, line cards, and
management card.
• Subscriber devices connect to the IES line cards through subscriber cables, and to the IP network
through the management card.
• Different line cards provide different subscriber services (ALC1132G-51, VLC1132G-51, and
VOP1164G-61).
• Connect the public switched telephone network (PSTN/ISDN) or a VOP1164G-61's port to the
POTS port on an xDSL line card to provide voice and DSL service to the line card's subscribers.
• The management card connects to and monitors the fan module through the backplane.
