Insert Allows for the switching time of the optical bypass switch. In this state, an

insert request is sent to the optical bypass switch. The ECM state remains

as Insert until the optical bypass switch has completed switching.

Check Used to conﬁrm that both the primary and secondary optical bypass switches

Local_b The B port is inserted into a local path and the A port is not.

Local_ab Both the A and B ports are inserted into a local path.

Wrap_a The secondary path is wrapped to the A port.

Wrap_b The primary path is wrapped to the B port.

C_wrap_a The primary path and secondary paths are joined internal to the node and
