Chapter 3. 9500 MXC Nodes
Vol. II-3-114 Alcatel-Lucent
• DAC GE 'C' in INU 2 provides the RWPR ring switch function and hosts the
local LAN. Note that the east, west and local LAN interfaces are all
port-connected; the DAC GE 'C' transport channels are not configured (no
backplane bus access is required).
• The east and west aggregated links are treated as one virtual link by RWPR.
If one link in the aggregated pair fails, ring switching does not occur - both
links must fail to initiate switching.
