Setting
Overall state of the DS3 line, which can be any of the
following states:
active—Line is enabled and a multipoint connection is
established.
does-not-exist—Link is not physically on the trunk
module.
disabled—Line is disabled.
loss-of-signal—Near end has loss of signal.
loss-of-frame—Near end has loss of frame (also
known as a Red Alarm).
yellow-alarm—Near end is receiving a Yellow Alarm
from the far end, indicating a loss of framing.
ais-receive—Near end is receiving an Alarm
Indication signal (AIS).
Redundant peer of this trunk port. If the current port is the
primary trunk port, the value identifies its spare
(secondary) trunk port. If the current port is the secondary
trunk, the value identifies the primary trunk port.
State of the redundancy function. The sparing-none value
indicates that redundancy is not enabled. If redundancy is
enabled and the current port is the primary trunk port, the
value can be primary-active or primary-inactive. If
redundancy is enabled and the current port is the secondary
trunk port, the value can be secondary-active or
secondary-inactive.
Current valid VCI range configured for the port.
Array of VPIs used for virtual channel switching.
For internal use only.
Number of F-bit errors. If three or more errors occur in up
to 16 consecutive F-bits in a DS3 M-frame, a DS3
out-of-frame defect is detected. If an out-of-frame defect is
consistent for up to 10 seconds, a DS3 loss-of-frame defect
is detected.
Number of P-bit parity errors. These errors occur when the
system receives P-bit code on a DS3 M-frame that is not
identical to the corresponding P-bit code that was calculated
locally.
Number of CP-bit parity errors.
Number of far-end C-bit coding violations reported through
the far-end block error count.
Number of bipolar violation (BPV) errors. BPV errors can
indicate that the line sent consecutive one bits with the
same polarity. It could also mean that three or more
consecutive zeroes were sent.
