Cisco 2511 show line result

[tuks]

We employ 2 Cisco 2511 routers as our dial-up routers. Our users always complain of slow response. Recently I found out one command to check the status of the lines. I use the "sho line" command to check it out.

The result is this:

Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns

A 16 TTY 9600/9600 F inout - - - 1055 17460 1/40

Can somebody tell where does that noise comes from ? Is it from our carrier or is it our modems or is it the interfaces ??

Hope someone gives an explanation

regards

I have only seen noise on the interface when the equipment
was not hooked up correctly. For example if a stop bit or a bit rate are set wrong. It would receive noises and would not activate the session. J.Fisher CCNA
