Remote controlled far end testing assistance
The perfect companion to the 3MTM Dynatel™ 965DSP Subscriber Loop Analyzer, the 3MTM 1342 Far End Device II (FEDII) provides remote controlled far end testing assistance during subscriber loop testing. Designed to enhance technician productivity, the FEDII connects to the far end on a cable pair to enable diagnostic testing to be performed from the near end controlled by the 3M Dynatel 965DSP.
Support of “auto” test function on Dynatel 965DSP, 965DSP-SA and 965DSP-B to facilitate loss measurement:
Insertion loss to 1.2 MHz
One technician, one test set: Pair Qualification
With a 3M Far End Device II (FEDII), one technician with a 3M™ Dynatel™ 965DSP Subscriber Loop Analyzer can perform end-to-end testing of metallic cable pairs. Commanded by the Dynatel 965DSP, the FEDII provides trace tone to verify cable pair connection, supports the 965DSP auto testing feature and qualifies loop performance up to 1.2 MHz (ADSL).
Controlled by DTMF signaling from the 965DSP, the FEDII can be commanded to remotely power-up, respond to test signaling, transmit tone on technician-selected conductors, or close relays to short the pairs in any combination. The unit can also be powered-up and commanded manually. The new FEDII may be connected in series with a working pair or bridged on to the test pair. In addition, the FEDII may be connected to two separate pairs allowing the end users to test two pairs.
Housed in a rugged, pocket-sized plastic case within a protective Cordura pouch, the 3M Far End Device features a power on/off LED and a test lead. The FED optimizes its replaceable 9V-battery life with an automatic power-down feature.
