Notes:
a. Refer to XXX-BD for descriptions of these tests.
b. Refer to TONE-PT for descriptions of these tests.
c. Refer to TDM-CLK for descriptions of these tests.
d. This test runs only on the standby Tone-Clock circuit pack in a Port
Network with duplicated Tone-Clocks (High or Critical Reliability systems).
The circuit pack must be a TN780 with firmware version 2 or above.
Clock Health Inquiry Test (#46)
This inquiry reads special data stored in memory to determine if this Tone-Clock
circuit pack had a loss of any of three clock types:
■ SYSCLK
■ SYSFM
■ SYSDCLK
If this data indicates this Tone-Clock circuit pack had a loss of any of these
clocks, the inquiry reports FAIL. In addition, if TDM-CLK error 1 is at threshold,
this test will FAIL. TDM-CLK error 1 indicates a suspect clock is at the edge of its
specified frequency. If the circuit pack did not have a loss of clock or TDM-CLK
error 1 at threshold, the inquiry reports PASS.
This is not really a test, in the sense that it simply reports status held by the
system, and does not generate new information or raise alarms. If this test fails
with no error code, there is at least one Major alarm against a Tone-Clock circuit
pack. If this test fails with an error code of 1, there is at least one Minor off-board
alarm against a TDM-CLK.
