CAB-EXFR (emergency transfer)
Issue 1 June 2005 743
PASS System software has control of Emergency Transfer within this cabinet. If
Emergency Transfer is currently invoked (the emergency transfer LED is
on), the cause could be a major alarm.
1. The following shows the error types that can cause Emergency
Transfer. If any of these errors appear in the log, then see TONE-BD
(Tone-Clock Circuit) on page 2327, and resolve these error types first:
● Error Type 3848, Aux Data 0
● Error Type 2305, Aux Data 0
These errors indicate the loss of one or more clock signals from the
reported TN2312BP circuit pack.
a. Examine the Hardware Error Log for errors reported against circuit
packs in the same port network, especially TDM-CLK, TONE-BD,
and EXP-INTF. Follow the repair or replacement procedures
indicated for any such errors found.
b. If the error is not corrected by resolving errors found in step 1, the
TN2312BP circuit pack should be replaced. See Replacing the IPSI
or Tone-Clock Circuit Pack on page 2337.
2. If none of the previous errors appear in the log, then check the
Emergency Transfer hardware.
