Repeater Extender
Informazioni
The T-BERD T1 Repeater Extender is a hand-held circuit card
extender packaged in a rugged plastic case, which provides
easy test access toTl signals at span repeater housings. The
T-BERD T1 Repeater Extender is designed to work in
conjunction with a T-Berd 107
107A, 209,209A, or 211
T-Carrier Analyzer to perform out-of-service testing or
monitoring of T1 signals along repeatered spans.
Through the use of switches and jacks, the T-BERD T1
Repeater Extender enables you to monitor T1 signals at
repeater inputs and outputs without disrupting the simplex
current. The T-BERD T1 Repeater Extender also further
sectionalizes span lines by performing signal loopbacks at
the repeater and by terminating repeater outputs.
1.3 STANDARD FEATURES
Four test access jacks permit monitoring of test signals at
the input and output of T1 repeaters. These jacks also
provide direct access to the T1 span for Time Domain
Reflectometer (TDR) and DC testing.
SIGNAL and CURRENT path switches enable the T-BERD T1
Repeater Extender to perform signal and current loopbacks at
span repeater housings.
The TRANSMIT switch terminates the SIDE 1 or SIDE 2 output
of a repeater with a 100-ohm load and allows test signal
insertion at any span repeater location without affecting
the simplex current.
SIDE 1 and SIDE 2 CURRENT SENSE TEST POINTS provide access
for an external volt-ohmmeter.
