TONE-BD (Tone-Clock Circuit)
Issue 1 June 2005
2351
 
Notes:
a. See 
on page 2539 for descriptions of 
these tests.
b. See 
on page 2353 for descriptions of these tests.
c. See 
on page 2252 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 
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.
