Circuit Startup Process Overview

CTP devices use UDP operational and maintenance (OAM) packets to initially discover the circuit on the remote CTP device, and to verify continued connectivity with the remote device. When a bundle is activated, the CTP device sends OAM packets to the remote circuit until the required number of packets is received. The circuit then changes its state to in-sync, and begins sending data packets.

Circuits continue to send OAM packets to the remote device at a configured rate. If the number of OAM packets that the CTP devices misses reaches a configured number, the state of the circuit changes from in synchronization to no synchronization.

You can also specify how many consecutive packets the IP network must drop before the CTP device restarts the circuit. After the circuit restarts, the CTP device must receive a specified number of in-sequence packets before it transitions the circuit from in-sync to running.
