T-BERD Outside Plant Tester
Smart Loopback/Command Code Option
This option enables the T-BERD Outside
PlantTester to send and receive
commandsfor maintenance switch
operation to minimize circuit downtime
and query performance data. This option
supports Teltrend
and Westell equip-
ment. In addition, this option enables
the user to utilize intelligent repeater
technology to qualify and isolate
troubles on outside plant spans.
The use of preprogrammed loopcodes
for intelligent repeaters enables the
T-BERD Outside Plant Tester to section-
alize span problemsprior to dispatching
maintenance personnel. It supports
Teltrend
, Westell, Wescom
, XEL
,
and TxPort
equipment. Please refer
to figure 1.
Test local loop for
HDSL/ISDN/DDS circuits
When equipped with the ‘HDSL/ISDN/
DDSMeasurement Option’, the T-BERD
Outside PlantTester is able to perform
loss measurements at 28 kHz, 40 kHz,
48 kHz, 82 kHz, 163 kHz, 196 kHz, and
392 kHz to assure proper signal level at
equipment inputs for HDSL, BRI, and
DDScircuits. In addition, the user can
ensure that the local loop does not
exceed the customer service agree-
ment requirements for maximum loop
length, including bridged tap length,
when provisioning HDSL, BRI, and
DDScircuits. This option also includes
preprogrammed HTU-C, HTU-R, and
doubler loop codes, which enable the
T-BERD Outside Plant Tester to quickly
sectionalize transmission troubles.
The option supports PairGain
,
Tellabs
, Adtran
,Westell, and
ADC
equipment. Please refer to
figures 2 and 3.
Turn Up and Troubleshoot DLC systems
The DLC/DS0 Analyzer Lid Option is a
tool for verifying DLC/DS0 circuitsand
contains features thatperform the
following functions:
Full duplexchannelmonitor
The T-BERD Outside PlantTester can
decode signaling bits in both direc-
tions on allchannels simultaneously.
The technician can listen to either
one or both directions of a VF circuit
by dropping the channel(s) to the
internal speaker or an externalTIMS.
Channelinsert
Channel insert allows an internal
test tone or voice and digits from
an external butt-setto be inserted
and controls signaling bits without
disrupting the remaining active
channels.
