Jan 7th, 2008

hello,

On cisco 3640 RAS I have a channel issue, users are deconneted intempesively.

With the modem debug I have this message:

Jan 7 09:25:15: CSM: MODEM_REPORT rcvd DEV_IDLE for call_id 0x14D, modem

not found due to wrong b channel number or b channel is deallocated

Jan 7 09:25:15: TTY44: DSR was dropped

Jan 7 09:25:15: tty44: Modem: READY->HANGUP

Jan 7 09:25:15: TTY44: dropping DTR, hanging up

Jan 7 09:25:15: Modem 1/11 CSM: (CSM_PROC_IDLE)<--ASYNC_DTR_DOWN

Jan 7 09:25:15: tty44: Modem: HANGUP->IDLE

Jan 7 09:25:16: TTY44: cleanup pending. Delaying DTR

Jan 7 09:25:16: TTY44: cleanup pending. Delaying DTR

Jan 7 09:25:16: Modem 1/11 Mica: PPP escape_map: Tx map = FFFFFFFF, Rx map

= 0

Jan 7 09:25:16: %LINK-5-CHANGED: Interface Async44, changed state to reset

Is it a configure problème, a hardware or a telecom compagny issue.

thanks for your helps.

Bests regards

Omar

better authenticate the dial-up clients before telnetting the device
