Telephone Butt Set with High Impedance Monitoring Analog
Description:
This telephone butt set is designed for installing, servicing, and maintaining analog telephone lines, offering all essential testing functions, including dial tone detection, call making and receiving, high-impedance monitoring, and both tone and pulse modes.
Features:
Talk, Ring, and Monitor test functions, switchable from the handgrip
Supports signaling via dial tone (DTMF) or dial pulse
High-impedance monitoring prevents disruption of data, conversations, or signals
A bright LED clearly indicates reversed polarity
Last-number redial memory (up to 31 digits)
Built-in voltage protection against surges, ringer signals, and accidental battery/power supply connections
Angled Bed-of-Nails (ABN) clips for secure connections
