Overview
Card LAN link
Maintenance communication is the exchange of control
and status data between IPE line or trunk cards and the CE CPU by way
of the NT8D01 Controller Card. Maintenance data is transported via the
card LAN link. This link is composed of two asynchronous serial buses
(called the Async card LAN link in
Figure 11 "Typical IPE trunk card
). The output bus is used by the controller for output
of control data to the trunk card.The input bus is used by the controller for
input of trunk card status data.
