a. All the failure Error Codes marked with (a) 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. See warning below.
b. All the failure Error Codes marked with (b) are almost transparent to the user. Again, 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. 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 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 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 or Tone-Clock 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 screen may imply that a TN780 is required.
