• Insertion of VC-AIS cells in forward direction for each VCC of this VPC. This informs all users
• Declaration of AIS/RDI
At the originating endpoint of the VPC the following actions are perfomed:
• Discard of VP-RDI cells (see
• Execution of the RDI state diagram shown in
• Declaration of RDI failure state after 3.5 seconds (standard) duration of RDI defect state.
The AIS state diagram executed at the sink endpoint of a connection is shown in
that in accordance for the anomaly-defect-failure mechanism only transitions to and from failure
state are notified to the microprocessor. This avoids unnecessary interrupts.
Data Sheet
VPC about the failure. RDI makes sense in cases where the failure of the line affects only one
direction. The automatic RDI generation in backward direction assumes bi-directional
connections with the same identifier (LCI) in both directions (see
sharing this VPC about the failure in the network (see
