Help configuring old Cisco 837 ISDN Router

Hi All,

Bit of a nightmare here, One of our sites' ADSL has gone down, and I've been tasked with getting their ISDN fax line working as a data connection too. We have an 837 at the customer's site, and one of them at our end with an ISDN-2 at each side, I have a config of their site's 837 router, but need some help as to what to program the router at our end with, in order to get it working.

Remote 837

What do I need to do with the router it connects to at Head Office?

Many Thanks
Andy

Before we go anywhere, could you tell us if data services enabled by telco for this ISDN lines? If so, what kind of signaling will CO (telco) switch will work with.

Here is a pretty nice guide how to configure remote access ntworking using BRI dialers

They were originally used for data before ISDN so yes I assume so, as this has been done in the past in the event of ADSL failure.

Regarding the signalling, I have no idea am afraid :-(

BTW, I'm wandering where do you connect the BRI port of Cisco? What kind of adaptors for your FAX do you have?

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

i'd confirm with the telco that the ISDN service is set to Point-to-multipoint  VS  Point-to-Point.
