dialup users trouble

[paltel]

HI,

i have clients with modem type PCTel have troubles when they want to access the network through AS (Cisco 3640), the problem that the credential verification took too many time and afterthat the AS will disconnect them, they have to repeat more than 3 or 4 times to have access. I will turn the debug on.

But, is there is any idea about this problem, or i need to add this modem type to the AS database?

Thanks in advance

After you make a reverse Telnet connection to the modem, you need to test the connection. Send the modem the AT command to request its attention. It should respond with OK. For example:

at

OK

If the modem does not reply to the AT command, check the following:

Look at the output of the show line 1 command. If it displays "no CTS" for the modem hardware state, the modem is not connected or powered on, and is waiting for data; or the modem might not be configured for hardware flow control.

Check your cabling and the modem configuration (echo or result codes might be off). Enter the appropriate AT modem command to view the modem configuration, or enter the command at&f to return to factory defaults. Refer to your modem documentation to learn the appropriate AT command to view your modem configuration
