Hi all,
Primary WAN link goes down and there is no redundant link at that site. There is no IT staff onsite. An Engineer need to login to the WAN router remotely via a normal PSTN connected to the AUX of the WAN router to debug/troubleshoot as to why it went down. Also, the Engineer needs to access other Cisco device such as Switch stack/PIX to troubleshoot using the same PSTN connected to a modem and/or Access Server.
I had a look at some site and some recommended a PSTN connected to a modem and Cisco AS 2511 which can connect up to 16 devices. But this is now obsolete.

Hello,
A good way which I have used many times before is to use either a NM-16A or NM-32A module into a 2600 or 2800 series router. Then connect your hosts up to these async ports.
You could then dial into the console port of this router, or buy an ISDN or modem WIC.
Hope this helps,
Michael.

Hi,
Thanks for the quick reply.
Could you please provide some documentation links.
We have a Cisco 3700 router as the Gateway and incase the WAN link go down, I need to access this same router via PSTN dialup remote access and also access other Cisco devices.
Thanks

Hello,
I have found some documentation for you.
Firstly, this is the product you can use to dial into your router, called a WIC-1AM-v2 for a 2800 series router:
http://www.cisco.com/en/US/products/ps5854/products_data_sheet09186a00801d66bc.html
or the WIC-1AM for the 2600 series:
http://www.cisco.com/en/US/products/hw/routers/ps274/products_tech_note09186a00800ad45b.shtml
Otherwise, a cheaper solution is to dial directly into the console or aux port of the router:
http://www.cisco.com/warp/public/76/9.html
and the cabling guide for wiring a console to an analog modem:
http://www.cisco.com/warp/public/701/14.html
The NM module you require for the 2800 or 2600 is the NM-16A or NM-32A:
http://www.cisco.com/en/US/products/hw/routers/ps274/products_data_sheet09186a0080091b8b.html
Finally, here is how to configure it all:

Hope this helps,
Michael.

Thanks Michael,
I believe this is called out-of-band console access. Sorry, im new in this field.
GW router is a Cisco 3725 (Cisco IOS Software, 3700 Software (C3725-ADVENTERPRISEK9-M), Version 12.4(7c))
and
VG router is a Cisco 2811 (Cisco IOS Software, 2800 Software (C2800NM-IPVOICEK9-M), Version 12.4(7c))
We'll this modules still apply to our routers?
Thanks again for your help.
