TONE-BD (Tone-Clock Circuit)
Issue 1 May 2002 8-1679 555-233-143
Notes:
a. See ‘‘XXX-BD (Common Port Circuit Pack)’’ on page 8-1872 for
descriptions of these tests.
b. See ‘‘TONE-PT (Tone Generator)’’ on page 8-1682 for descriptions of
these tests.
c. See ‘‘TDM-CLK (TDM Bus Clock)’’ on page 8-1604 for descriptions of
these tests.
d. This test runs only on the standby IPSI or Tone-Clock circuit 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.
e. See ‘‘ETR-PT (Enhanced Tone Receiver Port)’’ on page 8-755 for
descriptions of these tests.
Clock Health Inquiry Test (#46)
This inquiry reads special data stored in memory to determine if this IPSI or
Tone-Clock circuit pack had a loss of any of three clock types:
■
SYSCLK
■
SYSFM
■
SYSDCLK
If this data indicates this IPSI or 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 an IPSI or 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.
