Descriptions and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. For example, by clearing error codes associated with the
Service State Audit test (#256), you may also clear errors generated from other
tests in the testing sequence.
Order of Investigation
Signaling Link State Check test (#1251)
Service State Audit test (#256)
Call State Audit test (#257)
ISDN Test Call test (#258)
1. Destructive; ND = Nondestructive
Signaling Link State (#1251)
This test is nondestructive.
This test checks the current state of the signaling link. The test looks at the
board-level translations, checks that the board is physically inserted, gets the
state of the D channel and service state of the port.
The test passes if the signaling link (D channel) is connected and operating
normally. The test fails if the board is not installed, the signaling link is
disconnected, or if the port is out of service. The test aborts otherwise.
