18 SPE Mapper Functional Description
(continued)
I
SPE_J1MONMODE[2:0] = 101: the user will program the 16 expected values of J1 in
SPE_RJ1DEXP[1
—
16][7:0] in SDH framing mode, where the first byte of the message has the MSB set to 1.
The SPE mapper compares the incoming J1 sequence with the stored expected value, setting the state bit,
SPE_RTIM if they
’
re different. Any change in state is reported in bit SPE_RTIMD, using interrupt mask bit
SPE_RTIMM.
I
SPE_J1MONMODE[1:0] = 110 and 111 are currently undefined.
I
Unless bit PAIS_TIMINH (
Table 149
) is set, bit SPE_RTIMD contributes to the AUTO AIS control signal from the
SPE mapper to the VT mapper).
I
Unless mask bit SPE_RTIMM is set, bit SPE_RTIMD can generate an interrupt.
Table 536. J1 Monitor
18.14.3 B3 BIP-8 Check
A B3 BIP-8 even parity is computed over all the incoming bits of the TUG-3 frame, after descrambling, and com-
pared to the B3 byte received in the next frame. The total number of B3 BIP-8 bit errors (raw count) or block errors
is counted (selected through SPE_B3BITBLKCNT (
Table 149
)). Upon a performance monitor (PM) interval, the
internal running counter is placed into SPE_B3ECNT[15:0] (
) and then cleared. Depending on the value
of microprocessor bit SMPR_SAT_ROLLOVER (
Table 67
), the internal counter will roll over or stay at its maximum
value until cleared.
