B Drop Bus Port n Remote Payload Defect Indication: A 1 indicates
that a remote payload defect alarm has been detected (bits 5, 6 and 7 in
K4 (Z7) byte are equal to 010). The number of consecutive events used
for detection and recovery is determined by control bit V5AL10.
B Drop Bus Port n Remote Connectivity Defect Indication: A 1 indi-
cates that a remote connectivity defect alarm has been detected (bits 5,
6 and 7 in K4 (Z7) byte are equal to 110). The number of consecutive
events used for detection and recovery is determined by control bit
V5AL10.
Unused: These bits read out as zero.
B Drop Bus Port n J2 Loss Of Lock Alarm: Enabled when control bit
J2nSIZE is a 0, and control bit J2nCOM is a 1. A 1 indication occurs
when the alignment of the 16-byte J2 trace identifier label (message) has
not been established.
B Drop Bus Port n J2 Trail Trace Mismatch Alarm: Enabled when
control bit J2nSIZE is a 0, and control bit J2nCOM is a 1. A 1 indicates
that the stable 16-byte message did not match for one message time.
Recovery occurs when the J2 state machine loses lock and then
acquires lock with a 16-byte stable J2 message that matches the J2
comparison message written by the microprocessor.
Unused: These bits read out as zero.
B Drop Bus Port n Receive K4 (Z7) Byte: The eight bits in this register
position correspond to the K4 (Z7) byte received for the TU/VT selected.
Bit 7 corresponds to bit 1 in the K4 (Z7) byte.
B Drop Bus Port n Receive O-bits: The two nibbles (bits 7-4 and 3-0)
in this register correspond to the two sets of four overhead communica-
tion bits received in the TU/VT selected. Bit 7 corresponds to bit 3 in the
second justification control byte, while bit 0 corresponds to bit 6 in the
first justification control byte. The two nibbles written into this register
location will be from the same frame.
Same alarms as the following address locations (7-1), except that these
alarm states are latched.
Unused: This bit reads out as indeterminate.
