11.1.4 Administrative and Service States
OCHCCs, OCH trails, and OCHNCs occupy three different optical layers. Each OCH circuit has its own
administrative and service states. The OCHCCs impose additional restrictions on changes that can be
made to client card port administrative state.
The OCHCC service state is the sum of the OCHCC service state and the OCH trail service state. When
creating an OCHCC circuit, you can specify an initial state for both the OCHCC and the OCH trail
layers, including the source and destination port states. The ANSI/ETSI administrative states for the
OCHCC circuits and connections are:
•
•
•
OCHCC service states and source and destination port states can be changed independently. You can
manually modify client card port states in all traffic conditions. Setting an OCHCC circuit to
OOS,DSBLD/Locked,disabled state has no effect on OCHCC client card ports.
An OCH trail is created automatically when you create an OCHCC. OCH trails can be created
independently between OCH-10G cards and GE_XP and 10GE_XP when they are provisioned in
Layer 2 Over DWDM mode. The OCH trail ANSI/ETSI administrative states include:
