There should be information available from the vendor of an arbitrary short-haul modem telling you what speed it can push how far (longer distance-> lower speed). We were frustrated and slightly amused when we called the person who was the official Point-of-Contact for our campus asking what the milage was on one of our lines and got the reply that they didn't know and had never heard the question before. Gene the easiest answer to this question is to simply short out the line and use an ohmmeter. the number is ~6k ohm/mile but look in the aprop telco documents for the exact number. (you could also use a TDR if you happen to have on hanging around... that is also the only easy way to be sure that they didn't leave the loading coils on the line.)
