E1/T1
Configuration
From
the
'E1'
tabs,
the
status
of
each
tributary
port's
signal
status,
Alarm
Indication
Signal
and
performance
(ES
or
Error
Seconds),
can
be
easily
viewed.
There
are
4
items
that
can
be
configured
here
for
each
port.
Service
‐
The
port's
service
can
either
be
enabled
or
disabled.
When
disabled,
no
transmission
occurs
and
no
alarms
are
generated
from
that
port.
The
front
panel
LED
for
that
channel
will
be
OFF.
Line
Code
‐
This
will
configure
the
line
coding
performed
by
the
LIU
(line
interface
unit)
to
HDB3/B8ZS
or
AMI.
Auto
AIS
‐
When
enabled,
a
LOS
of
receive
signal
will
cause
an
AIS
to
be
transmitted.
This
lets
the
remote
side
know
their
transmit
signal
is
broken.
Loopback
‐
The
E1
supports
local,
remote
and
request
remote
loopback.
Refer
to
3.4.11
for
details
of
loopback
operation.
Performance
Monitor
Note
The
only
performance
monitor
parameter
available
in
the
Fiber
Multiplexer
is
ES
or
errored
seconds.
When
a
receive
signal
is
lost
(LOS)
the
ES
counter
will
increment.
The
counters
are
separate
for
each
channel
and
can
be
individually
cleared
by
using
the
"Clear
PM"
check
boxes
followed
by
clicking
"Set
Parameters".
The
"Clear
All
PM
Counter"
button
will
clear
all
the
channel
counters.
