Note that for modems which can measure Signal-to-Noise Ratios, 37 dB is the *best* that can be obtained on a connection through any form of 64Kbps/channel PCM digital carrier. The specification for a voice grade telephone line is only 24 dB. 28.8Kbps to 33.6Kbps (ITU-T V.34 protocol) Indicates the line is so close Camden 56k , Camden, NJ 56k CamdenCamden , 56k New Jersey, Camden 56k
