4. Interchange the IPSI or Tone-Clock circuits, using set tone-clock location. If the 

command succeeds, the interchange that previously failed has been accomplished and 
the problem has been satisfactorily resolved. If it fails, proceed to the next step. You may 
want to proceed in any case to definitively test all relevant components.

5. Interchange the t/c selector using set expansion-interface. If errors prevent this 

interchange, resolve them first.

6. Attempt again to interchange Tone-Clocks with set tone-clock location.

If the Tone-Clock interchange failed for both t/c selectors, replace the standby 
Tone-Clock circuit pack which could not be interchanged into and return to this step. (See 

on page 2337.) Test the new circuit pack 

as follows:

a. Execute set tone-clock location.
b. Execute set expansion-interface.

c. Execute the set tone-clock location command again.

If these commands successfully complete, the problem has been resolved.

If these commands successfully complete, the problem has been resolved.

If the IPSI or Tone-Clock circuit packs successfully interchange when one EXP-INTF is 
active, but not when the other one is, the t/c-selector circuit pack on the failing side is 
suspect.

d. Replace the EXP-INTF board that is active when the Tone-Clock interchange fails. For 

the Expansion Interface, see 

page 1176. Follow procedures in 

Maintenance Procedures (03-300192), and “Reliability Systems: A Maintenance Aid” 
for the DUPINT circuit pack

e. Make sure the new t/c selector is active and execute set tone-clock location.

f. If both Tone-Clocks can be interchanged into, and interchanges succeed when either 

t/c selector is active, the problem has been resolved.

o. Error Type 3840: this error is not service-affecting and can be ignored. It indicates that the 

circuit pack has received a bad control message from the switch.

p. Error Type 3848: the IPSI or Tone-Clock circuit pack had a loss of clock. If error 2305 is 

also logged, see Note k.

q. Error Type 3856: the IPSI or Tone-Clock circuit pack had a loss of clock. If error 2305 is 

also logged, see the note for Error Type 2305.

r. Error Type 3857 and 3858: these errors are reported by software when an uplink message 

is received from the active IPSI’s Archangel firmware. Both Error Types indicate that a loss 
of one or more clock signals were detected by the archangel, and subsequently restored by 
changing the CLKSEL lead.
