Hello! I have an interesting problem. We had a new phone system installed at our office.
The basic issue is that we have four internal Macintosh modems (set to only send faxes - the modem doesn't receive any faxes) and one fax machine connected to a single fax line. If all five devices are connected to the line then no calls can be made or received. After unplugging the devices one by one then the problem starts to clear up. Two modems were identified as causing troubles on the line. With these two modems unplugged, then calls can be made and received. Note that the two modems which now cause the trouble are the only ones that sent faxes before the new phone system was installed. If one of the two "bad" modems are plugged into the fax line, then when the line is called the incoming call receives a busy signal. If the "bad" modem is unplugged then the call will come into the fax machine properly. Then this modem was unplugged again and left off line. If the second modem is plugged into the line, when the line is called it rings approximately 1 1/2 times. The call is then answered and dropped immediately. If the "bad" modem is unplugged then the call will come into the fax machine properly. So to bypass any trouble that may be on the fax line, a line was removed from their telephone system and wired to the two "bad" modems only. When both of the test were performed again, one by one, then we received the same results. It should also be noted that there was a new telephone system installed at this site. The old system was an Avaya Partner telephone system. The telephones that were on the old system had analog ports attached to the bottom of them. The modems were plugged in directly to the analog ports on the phones, and not into direct dial tone as they are now. The new telephone system does not have these analog ports on the bottom of the telephone. Is it possible that by using the analog ports on the old system it was masking an existing problem? If anyone has any ideas or solutions they would be greatly appreciated. Thanks, Leah ________________________ Leah Dienes Fearless Designs 622 E.
