b. This error is logged and the port is alarmed when an alarm is raised on the
Announcement circuit pack because of a faulty condition with a common
circuit pack resource. Any one of the following alarmed errors on the

System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the Channel
Administration Memory Array (CAMA) Test, for example, you may also clear
errors generated from other tests in the testing sequence.
Channel Administration Memory Array (CAMA)
Test (#205)
This test is a memory device that stores information used to control the 140AY
device. The Angel asynchronously feeds the CAMA with the control information.
During the CAMA test, the Angel writes patterns into the CAMA, reads them back,
and verifies that they match. If the patterns do not match, the test fails. This test is
run periodically by the switch maintenance and by the Announcement circuit pack
in the background.
