Device connection

When the probe starts, its first action is to open a connection to the TCP/IP port. If the connection is successful, the probe then tries to ping the target adapter module to check that it is active.

When the probe has confirmed that the module is active, it starts to request alert data in the following sequence:

  1. The probe requests all active network element faults.
  2. The fault adapter module returns all the active network element faults to the probe.
  3. The fault adapter enables a reporting feature that forwards new network element faults to the probe at specified time intervals.
  4. The probe requests all active faulty circuits.
  5. The fault adapter module returns all the faulty active circuits to the probe.
  6. The fault adapter enables a reporting feature that forwards new faulty active circuits to the probe at specified time intervals.

Each network element fault or faulty active circuit acquired by the probe is used to generate an alert.
