’1’ ignores CRC of AAL1 byte
’1’ ignores parity bit of AAL1 byte
’1’ ignores sequence number of AAL1 byte
status bit indicating CRC error
status bit indicating parity error
status bit indicating single cell loss
status bit indicating multiple cell loss
status bit indicating a cell misinsertion error
status bit indicating interval since last cell exceeds
time_out_period (0828h) (reset when timeout
ceases)
status bit indicating the interval between two cells
has exceeded the time_out_period (0828h)
status bit indicating the interval between remote
SRTS values received was too short and one was
lost
status bit indicating the interval between local
SRTS values received was too short and one was
lost
Interrupt Enables
timing reference (usually ref_vca or ref_vcb), see
Table 28.
selects fnxi input, see Table 28.
time-out period between two cells (units - 1024
mclk cycles)
"keep 1 point out of X" and write to external
memory
pclk must be divided by K in order to match the
interval of 8 SRTS carrying cells, where K = P/Q,
P is normally the number of frames in the
scheduler, i.e. 375 for fully filled structured AAL1
Q is the number of channels open
