I am trying to toubleshoot a Router dialup connection where a user dails into the router to connect to the the Corporate network.
The User gets an error msg " remote computer didnot respond " when he tries to connec the router through a modem connected to the cisco 2600 async interface.whe i tried to reverse telnet to the Modem, the connection opens but junk characters keep coming and the modem don't respond to AT commands.I tried changing the speed in Line config mode.
When i tried calling the phone number of the Modem( Router end), i get a continous ring and the modem don't respond.
try "debug confmodem" and configure the line that the modem is connected to with either "modem autoconfigure type " (where is the modemtype as listed by show modemcap) or "modem autoconfigure discovery" (if your modem type is not listed).
I am happy to inform you that the problem is solved.I connected the Modem on a different Interface(Int s0/0) with ths same configuration & modem and it started working.
After that i configured this interface(Int S0/1) as sync interface and connected a Leased line RAD modem.The moment the cable(V.35) is connected to the interface, the router seems to be hanging and i lose connectivity on the Leased Line (S0/2).
I am 500Miles away from the place where the problem is and am trying to troubleshoot it through telnet.The Cisco 2610 router with 1 Serial and 2 low speed Sync/Async interfaces.2 Leased lines and one Router dialup.Now one LL is down as i am using this interface(S0/0) for Router Dial-up.
Could this be a Hardware problem.If so how can i confirm.Any of the show commands help in this.
