Communication Manager Maintenance Object Repair Procedures<br />

10. Replace the circuit packs one at a time, and wait at least 1 hour to determine if the problem<br />

has gone away. This procedure is disruptive and should be done after hours if possible.<br />

Instead of replacing the EI and SNI in systems where the PNC is duplicated, perform a PNC<br />

interchange using reset pnc interchange. If the problem goes away, replace either<br />

the EI or the SNI on the previously active PNC. Replace one at a time and make the PNC<br />

active again to see if the problem is fixed.<br />

Instead of replacing the Tone-Clock circuit pack in systems where the Tone-Clocks are<br />

duplicated, run set tone-clock to interchange Tone-Clocks. If the problem goes away,<br />

replace the previously active Tone-Clock.<br />

Also, before replacing a Switch Node Clock circuit pack, use set switch-node-clock if<br />

SNCs are duplicated in the carrier. If the problem goes away, replace the previously active<br />

SNC.<br />

11. Use the following steps to disable and enable synchronization to the same source. This<br />

may, in some instances, reset where a port network gets its timing.<br />

a. Use the status synchronization command to determine where synchronization is<br />

currently being obtained.<br />

b. Use the disable synchronization command to temporarily disable the current<br />

synchronization source.<br />

c. Use the set synchronization command to set synchronization source to where it<br />

was before it was disabled. See step a above.<br />

d. Use the enable synchronization command to enable synchronization.<br />

Verify whether or not slips continue.<br />

12. Onsite personnel can determine whether an IPSI or Tone Clock is providing timing by<br />

observing the amber LED on the faceplate.<br />

- If the LED is on 75 percent of the time and off 25 percent of the time, the IPSI or Tone<br />

Clock is externally synchronized to a master clock source.<br />

- If the LED is off 75 percent of the time and on 25 percent of the time, the IPSI or Tone<br />

Clock is providing timing.<br />

Facility Fault Sectionalization<br />

DS1 facility fault sectionalization involves looping around the DS1 signal at on-site access<br />

points to localize the source of the problem to equipment and wiring on either the near side or<br />

far side of the looparound point.<br />

WARNING: The<br />

! WARNING:<br />

facility fault sectionalization technique disrupts service. When you perform<br />

the looparound on a facility, make sure it is not the on-line synchronization<br />

reference or a system outage will occur.<br />
