A Drop Bus Port n Tandem Connection OEI Counter: An 8-bit counter
which counts the number of OEI errors detected in bit 6 in the N2 (Z6)
byte for the TU/VT selected when the tandem connection feature is
enabled. The counter saturates at full count and is cleared when it is
read.
A Drop Bus Port n Receive V4 Byte: When control bit V4EN is 1, the
eight bits in this register position correspond to the V4 byte received in
the TU/VT selected. Bit 7 corresponds to bit 1 in the V4 byte.
Same alarms as the following address locations (7-0), except that these
alarm states are latched.
B Drop Bus Port n TU/VT AIS Alarm: A 1 indicates that an AIS has
been detected in the V1/V2 pointer bytes for the TU/VT selected.
B Drop Bus Port n Loss Of TU/VT Pointer Alarm: A 1 indicates that a
loss of pointer has been detected in the V1/V2 pointer bytes for the
TU/VT selected.
B Drop Bus Port n TU/VT Pointer Size Error Indication: A 1 indicates
that the receive size indicator in the pointer (Bits 5 and 6 in the V1
pointer byte) is not 10 for the TU/VT selected. The detection and recov-
ery time is immediate.
B Drop Bus Port n New Data Flag Indication: A 1 indicates that a New
Data Flag (1001 or 0001/1101/1011/1000) has been detected in the V1
pointer byte for the TU/VT selected (i.e., bits 1-4 in the V1 byte are the
inverse of the normal 0110 pattern or differ in only one bit, with a correct
size indicator and a valid pointer value).
B Drop Bus Port n Remote Server Defect Indication: A 1 indicates
that either a remote server defect alarm has been detected (bits 5, 6 and
7 in K4 (Z7) byte are equal to 101), or an RDI has been detected coming
from older equipment (bit 8 in V5 byte equals 1 when bits 6 and 7 in K4
(Z7) byte are equal to 00 or 11). The number of consecutive events used
for detection and recovery is determined by control bit V5AL10.
B Drop Bus Port n Remote Failure Indication: A 1 indicates that bit 4
in the V5 byte is equal to 1 for the TU/VT selected. The detection and
recovery time is immediate.
