S/UNI®-8x155 ASSP Telecom Standard Product Data Sheet
Released
When TIMODE is high, RTIUV is set low during the stable state which is declared after
having received the same trace byte for 48 consecutive SONET/SDH frames. The stable
byte is declared the accepted byte. RTIUV is set high when mismatches between the
accepted byte and the received byte have been detected for three consecutive 16 byte
windows. The 16 byte windows do not overlap and start immediately after the 48th
persistent byte.
RTIUI:
The RTIUI bit is a logic one when stable/unstable status of the trace identifier framer
changes state. When RTIUV changes value, RTIUI is set high. This bit is cleared when this
register is read.
UNEQV:
The unequipped value status bit (UNEQV) is indicates the equip status of the path signal
label. The functionality of this register is controlled by the PSLMODE register.
When PSLMODE is set low, UNEQV is set high when the accepted path signal label
indicates that the path connection is unequipped. UNEQV is set low when the accepted
path signal label indicates the path connection is not unequipped.
When PSLMODE is set high, UNEQV is set high upon the reception of five consecutive
frames with an unequipped (0x00) label. The bit is set low when five consecutive frames
are received with a label other than the unequipped label. The five consecutive labels
needed to lower the alarm do not need to be the same. The assertion of UNEQV will
automatically prevent a path signal label mismatch alarm.
UNEQI:
The UNEQI bit is a logic one when unequipped status of the trace identifier framer changes
state. When UNEQV changes value, UNEQI is set high. This bit is cleared when this
register is read.
