Connect 2 routers via POTS

2 different locations each have a regular dialup line (POTS).
How can I connect the two locations together using the POTS lines?

You need a router that connects to a telephone line and can be set up. SMC Barricade could do that, but I don't know if they are still available. This link suggests possibly:

http://www.smc.com/index.cfm?event=viewProduct&cid=1&scid=17&localeCode=EN%5FUSA&pid=858

Otherwise you need a modem with an ethernet connection on the internal side. I don't know of such a modem, but someone might. It would be something like this.

Directly (as you suggested in your question) you cannot do this.

Can you get DSL service installed on these lines?  That will make your job much easier.

Do you mean, like, 56Kb (theoretical) maximum POTS dialup?

The only way I'm aware of is by using something like Wingate.

Which means dedicating a computer on each end to act as a bridge between the POTS modems and routers.

On both ends, in Wingate...
Configure both dialup adapters as the external adapter (and it will have an external IP address from the ISP on both ends).
Configure the NIC on both computers as an internal adapter, with the IP address 10.10.10.10 /24.
Configure both Wingates to use NAT instead of proxy...

Setup the routers to use 10.10.10.1 and 10.10.10.2 on their WAN/internet ports (site 1 and site 2, respectively).  They can use 192.168.1.0 /24 and 192.168.2.0 /24 (respectively) on the LAN side. Unless your VPNs can work with the same network on both ends, anyway.

You should be able to setup Wingate in free mode like that (the three free users are 1.the wingate machine, 2. the dialup adapter, and 3. the internal NIC), though if it works for you like that, you should probably buy a couple licenses.

If I were to use Cisco 1800 routers with WIC cards would that work for a 10MB adsl connection?  Or does that only work if the building have a direct wire between them?

I don't think you can direct connect ADSL this way (but I stand to be corrected). You need the ISP's service to connect them.

With 1800's a WIC-1AM or WIC-1AM-V2 on each end should work instead of using a computer as the bridge.
e.g.

http://www.isptrader.com/network-hardware/cisco/wic-1am-v2/one-port-analog-modem-interface-card

or cheaper is the WIC-2AM
http://www.isptrader.com/network-hardware/cisco/wic-2am/two-port-analog-modem-wan-interface-card
if you want to try bonding 2 phone lines for 64Kb speeds.
The WIC-2AM-V2 modems there are 30x the price of the WIC-2AM's...

So am I correct to say that as long as I'm going  thru the telco (therefore not a direct wire between locations) I can't get anything faster than 56k?

John HurstBusiness Consultant (Owner)Commented:
If you only have dial-up service than 56K is as good as it gets unless you try bonding some lines (need your telco for that).  ... Thinkpads_User

I don't have dial-up, but I was thinking I could have one ADSL device call the other one and establish a connection at 10MB.

John HurstBusiness Consultant (Owner)Commented:
You need to go through your telco to get ADSL. Simply connecting two modems together with a two wire phone cord (long one) is not going to give you ADSL so far as I know (I stand to be corrected). ... Thinkpads_User

Thank you, and I wish you good luck with your connection. ... Thinkpads_User

Actually, without bonding adapters (as with 2 phone lines into a WIC-2AM or WIC-2AM-V2 on each end), the fastest you can get is 33600. 56k modems can DOWNLOAD at up to 56Kb, but can only upload at a maximum of 33.6K, so either direction will be limited to 33600 by the other end's max upload speed.
