Hello All,
We manufacture a modem product which has been tested and found to comply with FCC part 68 (& CS03). At a customer site, (a CO in Pittsburg) an installer was setting up our modems on a phone system and the modem would not communicate on the lines. It was determined ( by the site tech) that there was more line current on the phone line than our modem could handle and a resistor (attenuator) had to be put on the lines so it could function normally. Since Part 68 deals only with signal / levels that our equipment imposes onto the network, my question is: Is there a standard out there that: 1) defines what the acceptable line levels are or should be ? 2) defines such requirements for Modems ? 3) prescribes appropriate testing to ensure proper operation at higher than levels ? Am I making sense ?? I would appreciate any help from you. Thanks, George --------- This message is coming from the emc-pstc discussion list.
