SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
Algorithm 2: PPLMV is set to logic 1 when the accepted PSL does not match, according to
Table 1, the expected PSL. PPLMV is set to logic 0 when the accepted PSL
matches, according to Table 1, the expected PSL.
PUNEQV:
The path unequipped status (PUNEQV) bit indicates the current status of the UNEQ-P defect.
PUNEQV is set to logic 1 when the received PSL indicates unequipped, according to Table 1,
for 3 or 5 consecutive frames (selectable with the PSL5 register bit). An PUNEQV is set to
logic 0 when the received PSL indicates not unequipped, according to Table 1, for 3 or 5
consecutive frames.
PPDIV:
The path payload defect indication status (PPDIV) bit indicates the current status of the PPDI-
P defect.
Algorithm 1: PPDIV is set to logic one when the received PSL is a PDI that does not match,
according to Table 1, the expected PDI for 3 or 5 consecutive frames (selectable
with the PSL5 register bit). PPDIV is set to logic 0 when the received PSL is a
PDI that matches, according to Table 1, the expected PDI for 3 or 5 consecutive
frames.
Algorithm 2: PPDIV is set to logic 1 when the accepted PSL is a PDI that does not match,
according to Table 1, the expected PDI. PPDI is set to logic 0 when the accepted
PSL is a PDI that matches, according to Table 1, the expected PDI.
PRDIV:
The path remote defect indication status (PRDIV) bit indicates the current status of the RDI-P
defect. PRDIV is set to logic 1 when bit 5 of the G1 byte is set high for five or ten consecutive
frames (selectable with the PRDI10 register bit). PRDIV is set to logic 0 when bit 5 of the G1
byte is set low for five or ten consecutive frames.
PERDIV:
The path enhanced remote defect indication status (PERDIV) bit indicates the current status
of the ERDI-P defect. PERDIV is set to logic 1 when the same 010, 100, 101, 110 or 111
pattern is detected in bits 5, 6 and 7 of the G1 byte for five or ten consecutive frames
(selectable with the PRDI10 register bit). PERDIV is set to logic 0 when the same 000, 001
or 011 pattern is detected in bits 5, 6 and 7 of the G1 byte for five or ten consecutive frames.
