System Topology
In NC-SI each physical endpoint (NC package) can have several logical slaves (NC
channels).
NC-SI defines that one management controller and up to four network controller
packages can be connected to the same NC-SI link.
Figure 52
example the NC package has two NC channels.

NC Channel
Refer to operations where more than one of the network controller
channels can be enabled to transmit pass-through packets to the MC
at the same time, where arbitration of access to the RXD, CRS_DV,
and RX_ER signal lines is accomplished either by software of
hardware means.
Refers to the state of the network controller wherein pass-through
traffic is able/unable to flow through the sideband interface to and
from the management controller, as a result of issuing Enable/Disable
Channel command.
Defined as the direction of ingress traffic on the external network
controller interface
Defined as the direction of egress traffic on the external network
controller interface
Defined as the direction of ingress traffic on the sideband enhanced
NC-SI Interface with respect to the network controller.
Defined as the direction of egress traffic on the sideband enhanced
NC-SI Interface with respect to the network controller.
