The 3311 Automatic Ringdown Unit enables two telephones to ring one another and communicate. Lifting the handset of one telephone will ring the other until answered or the initiating telephone hangs up. Anytime both telephones are off-hook a talk path is established. A ringback tone is provided to the initiating telephone.
For multi-application environments, Algo also offers an Automatic Ringdown Circuit card. The 3311R Automatic Ringdown Circuit card is installed in Algo's 3500 Rack Mount Shelf which can hold up to 16 circuit cards.
The 3500 Rack Mount Shelf has wiring accommodation on the back of the unit with 25 pair connectors. Designed for 19" racks, the shelf requires 3 mounting spaces and comes with a power supply.
