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.
