Telephone Visual Ring Indication
Visual ring indication of a telephone is important for the hearing impaired, for use in noisy locations (or where ear protection is used), for fast or critical response environments, or for locations where audible ring volumes need to be lower to minimize disruptions. It is also important in multi-cubicle open concept office environments where it is often difficult to tell from a distance whether one's phone is ringing.
Typical applications requiring visual ring indication include:
- Recording studios, Broadcasting stations
- Hospitals, Nurseries
- Firehalls, Ambulance Dispatch, 911 centers
- Machine shops, Factory floors
- Nightclubs
- Facilities for the hearing impaired
- Busy/noisy offices
Algo offers a number of solutions for Visual Ring indication that are compatible with telephone technologies that include SIP, analog, Nortel, and Meridian Digital Centrex. In most cases, these solutions are made up of two parts: the "visual" part (the lights), and the "connecting" part (the interface device that allows you to connect to various telephone technologies).
