Teltone’s Telephone Line Simulators (TLS) make it easy to test or demonstrate equipment that connects to the North American telephone network (POTS), without requiring a phone company connection. Everything you need is in a compact, portable, AC-powered unit. The Teltone TLS-3 is a two-line version with Caller ID signaling.

Like a miniature central office or PBX, Teltone’s simulators provide accurate dial tone, audible ring, and busy signals to the telephones or other devices connected to them. Many functions of the TLS-3 are easily programmed with a touchtone phone.
