This is the worst case spec. Usuall lines come in with better end to end response. The "standard" way of testing a remote line used to be to make up a 16dB loss H pad and install it between the base and the remote to set the levels. Then remove the pad, connect the line, hook the remote to the other end and usually things worked out fine. Always figure a bit of extra loss since lines do change spec in various weather conditions.

So your total loss will be 18 +- 2 dB. I need to find my tone remote manual to get the answers to your other questions.

I usually set -10 dbm @ 1000 hz for +/- 3 khz deviation. ). 0 dBm for max deviation. and let the tone levels fall into place as you have indicated. If the line measures 6 db of loss @ 1000 hz, you may want to move the hold tone from -20 dBm to -17 or -14 dBm and the remainder accordingly. Also loss may vary with tone frequency, so loss at 1000 hz may be far different from loss at 2175 hz.
