These are the minimum and maximum thresholds
values for the per channel receive direction align-
ment FIFOs. If and when the minimum or maximum
threshold value is violated by a particular channel,
then the interrupt event
“
FIFO aligner threshold
error
”
will be generated for that channel and latched
as a
“
FIFO aligner threshold error flag
”
in the
respective per STS-12 interrupt alarm register.
The allowable range for minimum threshold values
is 1 to 23.
The allowable range for maximum threshold values
is 0 to 22.
Note that the minimum and maximum FIFO aligner
threshold values apply to all four channels.
These three per device control signals are used in
conjunction with the per channel
“
a1 a2 error insert
command
”
control bits to force A1 A2 errors in the
transmit direction.
If a particular channel
’
s
“
a1 a2 error insert com-
mand
”
control bit is set to the value 1 then the
“
A1
and A2 error insert values
”
will be inserted into that
channels respective A1 and A2 bytes. The number
of consecutive frames to be corrupted is deter-
mined by the
“
number of consecutive A1 A2 errors
to generate[0:3]
”
control bits.
The error insertion is based on a rising edge detec-
tor. As such the control must be set to value 0
before trying to initiate a second a1 a2 corruption.
