Modem getting NO CARRIER, but works for different locations
Posted on 2005-03-30
We use a payroll software that dials out to other remote locations via dial up modem and pulls the time.
On my computer, I open the software, i select the location and it dials to it, completing the handshake, and then it starts to pull the data.
We have our PCI Modem (Zoom) and it dials to a modem in our time clock.
It can dial to one location and talks to the modem, handshake and all.
It dials to the other location and it starts the handshake, but then it comes up NO CARRIER. You can hear it communicating with the other modem. And I know NO CARRIER usually means the remote modem dropped the connection. Correct?
So.......we had the time clock providers change the receiving time clock modems. Then neither worked. After swapping those clocks around a few times, as stated above, we can only successfully dial completely to one location.
We tried a different line and same results. I then tried it from our server, same unsuccessful results. Lastly, I tried it from my laptop and it pulls both stores fine. Modems talk with no issue.
But, I know after verifying everything, it doesnt sound like its my internal or external modem, phone lines, PC, or software.
Changed the internal modem..................no success
Changed to an external modem...............no success.
Changed settings such as the baud rate...........no success.
Verified the PC sees the modem through the Query...........
Set up IE to dial out. through the modem instead of our T1 lines.........it works fine.
Changed the PC for another PC, same problem, even with a third internal modem.......no success
Had the Telephone company verify the lines are strong...............
Had local phone guy verify the wiring of the jacks and phone box...........
Changed the phone cables and all other hardware...........
Reinstalled the time clock software........no success
I am lost. I tried everything once or twice. It starts to point one way, then it points to another. My personal conclusion is that our modem(internal or external) has a problem with the remote modem. The remote modem having the NO CARRIER issue is set up with its basic functions, nothing changed.
Any suggestions or guidance? Please help it has been three weeks of working around this issue.
