Here is a free idea to any company out there to make this thing. EMS week is comming soon to a shopping mall or school near you. For our local EMS week display we'd like to have a place where people can pick up a real phone and dial 911 and talk to a real 911 dispatcher. The folks could watch the dispatcher answer the call and interview the caller to send the proper help. (EMS is Emergency Medical Services system) For obvious reasons we don't want to use a PSTN line for this trick. Here is my idea for a product for this trick. A card to fit into a PC clone that will supply battery and supervisory tones to a normal phone, and a second jack for the heaset phone for the dispatcher. With this would be a piece of software to simulate a PSAP screen for the dispatcher. If one could make this card for a reasonable price ($100 - 150) they could be marketed to the 911 agencies across the country as a teaching aid for the public. At present I suppose I could borrow a small PBX (SX50) and program it to have a port with the extension 911.

Proctor & Associates makes a special version of the 49200 Telephone Demonstrator that simulates 9-1-1 trunks. Two of the lines are originating telephones, in two different simulated C.O.s, and the other two lines are incoming 9-1-1 trunks tied to the simulated C.O.s. The two POTS lines can call each other, or dial 9-1-1. The calls ring into the 9-1-1 jacks, and can be answered with plain old telephones, or a 9-1-1 console. Going off hook on an idle 9-1-1 trunk produces a 120 BT, just like a real 9-1-1 trunk. This is just like the 49200 Telephone Demonstrator, which simulates four telephone lines, but it has special software for simulating two B911 trunks. It does not forward any ANI, but it can be used with a special version of the Proctor Call Logger to simulate ANI.
