That would be called a milliwatt generator. It likely exists in their central office, but its typically used by their technicians to ensure new installations meet specs and sometimes in troubleshooting. Call your telco repair number and see if they will give you the telephone number for it.

milliwatt generator. (Obviously its not as good as using a CO milliwatt as now you have to take into consideration the loss from the second pstn line, but it is a way to get a handle on the transmission loss values, etc.) Would the txgain on the 2nd line also come into play? I guess
