If it's an Ernest, there should be a EPROM which has a label with some numbers and letters on it. That will tell what board it is.
You need the program T2 which is a DOS based program to talk to the board. There was a display that connects to the board so one can program the board in the telephone with the touch pad. Ernest made a 7C, a 7D and a 7D3 board. They all programmed the same, but had different features and were designed for different dial pads (AT&T, GTE, etc.)
As far as rates are concerned, Rates Technology supplied the rates for a given area code. However, one can program the Ernest for simple coin deposit and time limits per call and that can be zero all the way to $10 a minute. The key is to find the model number. It will be on the board.

OK, so the phone is actually turns out to be an Ernest Telecom. And I'm most likely going to keep it after replacing the damaged handset in shipping. My questions are:
I'm not sure of exact model number of it, how to find it?
Is this a good reliable long lasting phone?
How to program it?
Currently, it seems to dial out 7 digit local calls unlimited time or at least 7 mins that i had a call active for,for a quarter, 10 digit it asks $2.65 for 4 mins. I really need a few area codes to work with a quarter, is this possible out that would apply to all 10 digit numbers?
How expensive is it to maintain one down a road of a few years?
