Description

The Bell SBI-145 is a state of the art Craftsperson’s test set. It employs the latest and most advanced circuit designs making it possible to combine the following signaling methods in a simple, easy to use “butt set”: Touch Tone (TT), Dial Pulse (DP), and Meridian Digital Centrex (MDC*) dialing. MDC is also called Meridian Business Set (MBS*) and Enhanced Business Service (EBS). The SBI-145 does not work on ISDN or other fully digital lines. MDC is used with Nortel M5000 series sets.

The SBI-145 is very light, self contained and line powered. It provides tip and ring identification and audio/visual indication of POTS ringing. Last number redial and a nine number, twenty three digit repertoire memory facilitate dialing. High impedance monitoring, microphone muting, and ground start features are standard and packed in a rugged, easy to use case.
