About Us

Welcome to Technical Excellent entry control system manufacture-American Communication & Networks Corp.!

We are a company with a rich history and an even brighter future. Our origins date back to 1993, when a group of ex-Bell Labs MTSs founded American Computer & Networks Corp. in Lisle, Illinois. Since then, we have been dedicated to providing our customers with the most advanced and reliable products and services possible.

In 1994, we acquired a PBX division, and in the process of adding an entry control system to the PBXtra ACD (Automatic Call Distributor) and CCS (Computer Control Switch), we realized that there was a need for a universal compatible entry system that would work with any PBX, Key System, or FXO’s devices. And so our flagship product, the DoorBell Fon, was born.

The DoorBell Fon is the most versatile entry control system on the market today, and it is trusted by interconnect company, electricians, alarm companies, security firms, home automation contractors, lock smiths, and entry control contractors around the world. If you’re looking for a reliable and easy-to-use entry control system for your business or home, look no further than Technical Excellent DoorBell Fon!
