Table 8-1 - continued. CM4 Diagnostic Counters
Counter Name (NMS or SCL) Update Rate / Method Severity Effect on System Function & Notes
Accumulated Received Line Code
Violations
NMS: Acum Line Code Violation
Cnt
SCL: ABPV
Accumulated counter is
incr
em
ented by adding
current counter every second.
Minor Low level of Line Code
Violations has a minimal
effect on system if not
accompanied by other
trouble conditions.
Counter reports accumulated
count of Li
ne Code Violations
received at the Common
Module. Line Code Violations
are pulses of incorrect polarity
in the received signal.
Typically, this denotes errors
or noise present in the T1
signal at the multiplexer port or
improper AMI/B8ZS line code
configuration.
Accumulated Received Path Code
Violations
NMS: Acum Path Code Violation
Cnt
SCL: ABERS
Accumulated counter is
incr
em
ented by adding
current counter every second.
Intermediate Low level of Path Code
Violations has a minimal
effect on system if not
accompanied by other
trouble conditions.
Counter reports accumulated
count of Path Code
Violations
received at the Common
Module. Path Code Violations
are bit errors in received signal.
In ESF framing mode this
equals to the CRC6-error
count. In SF mode, it is the
framing bit error count.
Typically, this denotes errors
or noise in the T1 signal at the
multiplexer port or improper
SF/ESF line format
configuration.
Accumulated Received Frame Bit
Error
M-DACS-T1 RFL Electronics Inc.
NMS: Acum Frame Bit Error Cnt
SCL: AMFOS
Accumulated counter is
increm
ented by adding
current counter every second.
Intermediate When Frame Bit Error
condition exists, payload
traffic may be corrupted.
Disturbance may spread to
other nodes.
Reports accumulated count of
Fram
e Bit Error at the
Common Module. Frame Bit
Error is defined as errors in the
framing pattern. Typically, this
denotes bit errors or bad T1
signal at the multiplexer port,
improper SF/ESF line format
setting or improper network
timing configuration.
Accumulated Received E-Bit errors
(E1 only)
NMS: Acun Ebit Cnt
SCL: AEBIT
Counter contains result for
previous 1s inter
val.
Intermediate Payload traffic has been
corrupted. Severity needs
to be checked at receiver
node.
E-Bit errors are returned to the
re
porting CM when it has
transmitted frames which fail
CRC check. This denotes bit
errors on the transmit side.
