Demand test descriptions and error codes - Avaya Support

Maintenance Demand Tests
a. This error may affect users if the failure is on the active tone generator. When this type
failure is detected, the system will attempt to move the tone generation function to the
alternate IPSI or Tone-Clock circuit pack, if one is present in the affected port network.
When the tone generation facility fails in this way, especially in a port network without
duplicated IPSI or Tone-Clock circuit packs, the faulty IPSI or Tone-Clock circuit pack should
be replaced promptly.
b. This error is almost transparent to the user. When this type failure is detected, the system
will attempt to move the tone generation function to the alternate IPSI or Tone-Clock circuit
pack, if one is present in the affected port network. Users may or may not hear any noisy
tones. This type of failure affects maintenance on other objects. Maintenance may not be
able to run on other objects which use the tone generation facility (that is, Tone Detector
circuit maintenance). In this case, the IPSI or Tone-Clock circuit pack can be replaced as
suitable to the customer.
c. Error code 115 may also be caused by TDM bus corruption. There may be 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.
Enter 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 or Tone-Clock circuit pack retested. If this does not clear the
problem, the IPSI or Tone-Clock circuit pack should be replaced and the new one tested. If
the problem persists, follow the instructions for TDM-BUS (TDM Bus).
Tone Generator Update/Audit Test (#41)
This test refreshes the active tone generation facility with all the time slot tone information. This
test also triggers inline error messages the IPSI or Tone-Clock circuit pack generates when it
detects problems by itself.
A check is 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 screen may imply that a TN780 is required.
This test runs on the following maintenance objects:
● TDM-CLK (TDM Bus Clock)
● TONE-BD (Tone-Clock Circuit Pack)
● TONE-PT (Tone Generator)
