What is a DEEs Switch

[TelecomHeadache]

I am looking for documentation related to a DEE Switch. All I know is that if the Megalink line goes down you would flip the switch on the DEE connection so the calls can now be routed from the Megalink line to the Analog lines as fail over. But I have no docs on how it does this. I also beleive that the Analog and Megalink feeds to the DEE are directly from the Teleco and after the DEE is internal to the site as it then connects directly to the PBX, not sure exactly about that one. Any help on where I can some further if related on DEE Switches is great, thank you.

This is a power failure switch.
It will not connect to your megalink.
The way these work is you route analog lines through them to the switch, you then route some analog phone sets through them. The analog sets normally work off the switch but if you experience a power failure and the switch goes down it automatically connects those analog sets to the incoming analog lines.
