Cisco 837 help please

Hi all,
I'm trying to implement a network connection to a building that's 2 miles away from our network hub. We don't have fiber running to the building, and we currently have telco going there. We are using a standard twisted pair rj11 to carry the signal to the building, but we don't have anything to push the actual network signal that far.

Our Cisco rep said to purchase 2 Cisco 837's and connect them back to back.

Only problem is that there's no documentation that I found that explains how to do this. I know that I have to set one for a CO signal and another one for a CPE signal, but after that I'm completley clueless as to how to go about it. I've contacted Cisco TAC, but they don't have a clue as to what I'm going on about.

Can anyone give any insight?!?

Please?

Hi Norm,

Sounds a bit odd to me. A Cisco 837 is an ADSL router, so if you have got ADSL to both buildings you could set up a VPN between them. That would work and be quite easy, but you have to go through the phone system, you can't just back to back 837's on one long cable.

Cheers
 
If you have an end-to-end copper cable between the two buildings (i.e. it doesn't go through the telephone exchange) then you could use some line drivers and a pair of routers connected on the back of them:


There are lots of line drivers available some of which have built-in ethernet bridging capabilities so you don't even need additional routers. I would however put a pair of routers in to isolate the two networks but it's up to you.

Hellbabe,
According to Cisco, these should work back to back with just copper cable going between them. Without a DSLAM. But I'm having doubts because of the lack of documentation.

ADB100,
I'd love to be able to use these, but we would have to use what we have, not purchase additional equipment. It's a copper line going from the MDF to the outlying buildings. It's all contained within our network, currently we are using hdsl signals to get the information out there. We are using adsl signals also, and according to everything that I've been reading, hdsl and adsl don't work together due to the signaling issue.

I appreciate the posts though. I've got a call in to our local cisco rep to see if I can get him out to our site, since he's the one that suggested it to us.
