A typical lineman's handset integrates an earpiece, a mouthpiece, a dialing interface, and a set of test leads for connecting to the telephone circuit. Originally, lineman's handsets featured a rotary dial, but modern sets use some variant of the standard 12-button DTMFkeypad and also employ an amplifier for speaker use. Most handsets are designed to be used with analog "POTS" lines, and have limited or no function with digital circuits. Older telephone linemen also referred to the handset as a "Goat".
In addition to the basic features listed above, handsets often include one or more of:
A mechanical hook for hanging the set from a tool belt. On some sets, it may be moved to the receiver side, mouthpiece side, or removed altogether.
Typical useedit
A lineman's handset typically connects via a pair of test leads, not the modular connector found on most consumer telephone equipment. The test leads will feature some combination of alligator clips (to connect to bare wires), a piercing spike or "bed-of-nails" (for insulated wires), and something designed to fit a punch block. Adapters designed to fit other punch block types, heat coil sockets, or modular jacks may also be used.
When connected to a line, a lineman's handset is essentially indistinguishable from regular subscriber equipment. The technician can do one or more of monitor an active call, answer incoming calls, and make outgoing calls. Common tests include checking for dial tone, using ANAC to identify the line, and using a ringback number.
