Notes:
a. A 1 error indicates that there has been 8 or more Processor Port Network
circuit pack removals in less than 15 minutes. This action may be forced
manually by removing power to a port carrier or pulling out at least 8 port
circuit packs within 15 minutes. The generation of this error may indicate
that there is a problem with the Switch Control circuit on the MSSNET
circuit pack or that there is a problem with the TDM bus. Three successful
completions of the Control Channel test (#94) will resolve the MAJOR
alarm caused by this error.

b. A 2 error indicates that the Switch Control Channel Transmission test (#94)
failed. This error may not cause a Switch Control alarm if Error Type 769 is
also present since this error may actually be caused by the loss of clock

After a spontaneous SPE interchange has occurred, the Alarm Log retains for three hours a record of any
MAJOR ON-BOARD alarm against an SPE component that took place before the interchange. If a
spontaneous interchange has occurred (as indicated by STBY-SPE error type 103 or the display
initcauses screen), and such an alarm is logged against SW-CTL, then replace the standby MSSNET
circuit pack using the "lock-and-power-down" procedure described in
