The Sage Instruments 930A Communications Test Set combines the functions of a Voiceband Transmission Measurement Set, Return Loss Measurement Set, and a Dial Pulse, Touch Tone (DTMF), and Multi-Frequency (MF) Sender in one lightweight package. The test set also provides Talk Battery to enable the user to talk over the trunk under test.

This test set, while of general purpose in nature, is particularly useful for DEMARC and Central Office testing, as well as PBX and Digital Switch installation testing. It is capable of performing all transmission and signaling tests required at these locations, including those for Feature Groups A - D (Equal Access). The 930A can completely simulate either a PBX or Central Office switch (Local or Toll).
