Provisioning
On
initial
installation,
the
TR
DDS
‐
DP
is
provisioned
according
to
the
factory
default
settings.
False Loopback Immunity
ADTRAN’s
Protected
Loopback
family
of
channel
units
includes
an
algorithm
compatible
with
SARTS,
Hekimian,
TPI,
and
other
test
systems
that
virtually
eliminate
false
latching
loopbacks.
Immunity
is
automatically
enabled
at
64
kbps.
In
addition,
ADTRAN’s
Protected
Loopback
family
features
a
protected
loopback
mode
for
further
false
latching
loopback
protection.
Latching Loopback
Latching
loopbacks
are
always
enabled
except
when
temporarily
disabled
via
the
protect
loopback
features.
When
64
kbps
is
enabled,
placing
SW1-3 (PLB)
to
OFF
will
permit
the
TR
DDS
‐
DP
to
respond
to
the
legacy
latching
loopback
sequence
as
described
in
TR62310
and
ANSI
T1.107.
At
64
kbps,
placing
SW1-3
to
ON,
the
TR
DDS
‐
DP
will
enable
ADTRAN’s
Protected
Loopback
mode.
Control Protocol
Remote
access
to
provisioning
and
status
information
is
accomplished
using
either
ADTRAN
Digital
System
6
Message
protocol
defined
in
Control
and
Diagnostic
Procedures
Practice,
Section
6032991
‐
6,
or
through
the
craft
interface
on
the
Total
Access
1500
SCU.
Digital
System
6
is
supported
by
the
TPI
108/109
and
105
portable
test
sets
and
is
supported
by
Hekimian
React
2001
Revision
1900
remote
test
system.
The
TR
DDS
‐
DP
network
elements
comply
with
ANSI
T1.107
‐
1995,
“Digital
Hierarchy
Format
Specifications
Annex
G”
which
allows
remote
provisioning,
querying,
and
performance
monitoring
via
in
‐
band
control
of
network
elements.
NOTE
The
REACT
2001
GUI
software
Release
1.900
supports
ANSI
T1.107
‐
1995.
Remote
access
is
accomplished
using
a
defined
set
of
in
‐
band
DS0
byte
sequences
similar
to
the
latching
loopback
sequence.
Commands
issued
via
the
test
system
are
recognized
by
the
individual
channel
unit
which
responds
with
the
appropriate
byte
sequences.
These
in
‐
band
commands
can
be
used
to
verify
options
via
dialogs
with
REACT
2001,
TPI
108/109
and
TPI
105
test
sets.
Unit
CLEI,
serial
number,
provisioning,
and
performance
information
can
be
retrieved
remotely
using
the
Digital
System
6
protocol.
