Trouble connecting to modem. Need some help.

Hello: I am new to working with Cisco products and I am trying to setup my 1760 router to make a dialup connection to my ISP with the WIC-1T serial card and an external V.92 modem. I realize it's an involved process and I am trying to read all the Cisco documents that relate to my situation. I'm taking it one step at a time. Right now I can't open a session to the modem to look at it's configuration (I'm doing this in hyperterminal in MS Windows with a console connection). Also I think I have properly put the Serial interface into async mode, but the Serial interface never seems to go into an up state. Slot 0 LED is on, CONN led on the card is on when the modem is on. Power and transmit LED's on the modem are on. There must be some configurations I have missed. Help would be appreciated. Below is some output. Thanks Bill

Hi Bill,

You may wish to investigate Cisco's WIC-1T Sample Configuration:

Hope this helps.

to access the modem, you would use a reverse telnet session.

see Cisco doc

The reason that you attempt to telnet from the router to itself on port 2001 is failing is that the interface

192.10.0.3 is down.

Plug something in to bring it up and that will be one problem out of the way. IF you dont have the facilities to bring up the ethernet port then create a loopback interface with any address you care and use that. Of course the "localhost" address should work (127.0.0.1) but I have had problems with that (not on cisco) and don't trust it.

"When the port is in data terminal equipment (DTE) mode, the CONN LED indicates that Data Set Ready (DSR), Data Carrier Detect (DCD), and Clear To Send (CTS) have been detected. When the port is in data communications equipment (DCE) mode, it indicates that Data Terminal Ready (DTR) and Request To Send (RTS) have been detected."

Yours says: CTS noDSR DTR RTS

I forget what to make of that. Check out the telnet and report back.

show run int se 0/0 woudl be good. also details of the cable(s)

Thank you both for the leads. I was able to telnet to the modem after I connected my laptop to the ethernet port on the router, this brought fastethernet0\\0 up/up. But when I terminated the telnet session IOS told me that the modem autoconfigure failed. I'm wondering if this because the serial interface is still down/down (no matter what I do, proper cables, power all around, IOS configured as cisco recommends). At this point I have taken off the ip address to see if it was causing a problem. Or weather I just have to get to the point where I start a call and it will come up. Any comments on this would be appreciated.

Cisco doc on router modem connections says this is the normal idle state.

I hooked my laptop into the ethernet port and was able to telnet to the modem.

modemcap entry Multitech:MSC=&FS0=1&C4&D3$SB115200 ! ! interface FastEthernet0/0 ip address 192.10.0.3 255.255.255.0 speed auto ! interface Serial0/0 physical-layer async no ip address encapsulation ppp ! ip classless no ip http server no ip http secure-server ! ! control-plane ! ! line con 0 line 1 modem InOut modem autoconfigure type Multitech transport input all stopbits 1 speed 115200 flowcontrol hardware line aux 0 line vty 0 login modem autoconfigure discovery line vty 1 4 login ! end

I checked twice, I have the right cable Cisco CAB-232MT 60 pin at router and 25 pin at modem (males) Is it possible my modem cap is wrong? Should it have the MSC= at the front? When I terminate the telnet session IOS tells me the modem auto configure has failed.

11:31:23: %TTY-3-AUTOCONFIG: TTY1: Modem auto-configuration failed Can you shead some light on that?

Thanks

Sorry not really. I just spotted the telnet thing. I have never used a modem on a router.

nice.

I can just offer general troubshooting advice.

Remove everything you don't need from the config and try basic stuff.

E.g. when you send the modem AT go you get OK back?

Look at the debugs described in the docs.

DEBUG has a few gotchas.

In general possible performane hit is /huge/. Howerer that is not an issue here.

logg buff deb logg buff 30000 logg con

If you are telnetted to the router you need to issue

term mon

term no mon ! to turn off

sh log

In general I don't have console logging on for production.

Please post the complete config as it now stands after you remove the following:

config t

line vty 0 no modem autoconfigure discovery end wri mem

Also for future debugging, suggest you configure:

config t logging buffer 10000 debug no logging console end wri mem

see Cisco doc "Understanding the 1-Port Serial WAN Interface Card (WIC-1T)"

which also referrs one to the following Cisco doc for more info on using the WIC-1T in async mode "If your platform supports async, then use the physical-layer async command for async mode. Such an application is useful to connect an external modem to the router. Refer to the document 2 Port Async/Sync WAN Interface Card (WIC-2A/S) for an example."

see Cisco doc "Configuring Dialout Using a Modem on the AUX Port"

In your case the modem is not on the AUX port but the serial 0/0 which has been configured into async mode op operation

Hi Merv,

They will not need a CCO Login with the following two web page alternatives.
