Maintenance Object Repair Procedure
c. Error code 115 may also be caused by TDM bus corruption. This normally
means a physical problem with bent backplane pins, TDM/LAN bus
cabling, or TDM/LAN bus terminators. Such physical problems should
especially be suspected if board replacement or other physical activity has
occurred just before this error is observed.
Use display errors to look for errors on other circuit packs in the carriers of
the same port network as the indicated Tone-Clock circuit. If any are
found, they should be resolved if possible, and the IPSI circuit pack
retested. If this does not clear the problem, the IPSI circuit pack should be
replaced and the new one tested. If the problem persists, follow
instructions for TDM bus maintenance in this manual.
Tone Generator Update/Audit Test (#41)
The active tone generation facility is refreshed with all the time slot tone
information. This test also triggers in-line error messages the IPSI circuit pack
generates when it detects problems by itself.
A check is also made between the type of Tone-Clock being tested and the type of
Tone-Clock needed based on system administration. The administration on the
system-parameters country-options form may imply that a TN780 is required.

8-1194 Issue 1 May 2002
Description / Recommendation
The system was not able to allocate all the resources needed for
this test.
System resources required for this test are not available.
The system requires a TN2312 Tone-Clock circuit to support the
administered country-options tone-generation parameters.
1. Check the administration on the system-parameters
country-option form. Specifically, the Base Tone Generation
Set on page 1 and any custom tone administration beginning
on page 2.
2. Replace any existing Tone-Clock circuits with a TN2312.
The tone generation facility has been successfully refreshed with
its time-slot translation and system administration is consistent with
this type of Tone-Clock.
1. Display the Hardware Error Log via the display errors
command to make sure this circuit pack did not generate new
errors.
