UPLEC MODEL No. 4403A
The tester detects the presence of an HDB3 encoded digital signal at 2048 Kbit/s and 8448 Kbit/s. Operating in a 75 ohm Digital Line System this signal will be available at a Type 43 connector point. The presence of the signal, having an amplitude of 2.37 volts peak, will cause an LED in the body of the Tester to illuminate. The Tester is not calibrated to any standard and is only used to indicate presence of the specified signal.
The Tester is used to establish signal presence on a particular type 43 connector i.e. for continuity checks or location.
