I would put broadband Internet access in at all locations and run VPNs from the small offices back to the central office. Most Internet providers can help you with the gear selection. Nortel, for example makes some boxes which are a small firewall/router for the remote location and a larger capacity unit (to handle multiple simultaneous calls) for the central office.

If that is not possible, then how about setting up your users to dial-in, with either ISDN or analogue. You could install a PRI in the central office along with an access server (Cisco makes some that are perffect for this). You will need a module which can handle BOTH analogue and ISDN. Then have your remote users setup with their choice (or depending upon availability) ananalogue or ISDN dial-out service.

In theory, you could run just plain old Ethernet (fibre or even copper) or Token Ring, but you would need repeaters. Repeaters need power, and physical security against vandalism. The biggest issue is that in most parts of the world there are regulatory issues preventing just anybody from laying cables down the public rights of way.

Apart from the suggestions by ebob regarding ISDN (or other dialup) you could think of infra-redlaser / radar connections from your client locations to your office. However, this would mean a clear-sight range between the clients and the office. Theadvantage is that you skip the official regulations regarding cable-digging!

If you don't want to make use of the Internet you can use a private dialin solution like RAS to establish the connection. It depends on the frequency / duration of the clients if this is suitable for 13 clients.

hello,
I think that "E" has cover all the bases but beside plain Dial-up and ISDN. U can have a xdsl connection via the PSTN. U by a DSL concentrator and each client will have his router connected to your concentrator. This solution is both permanent connection and dial-up you and your client can agree on what it should be. Furyther more these connection could sopport more users in each location without have to invest once more. For that purpose u can use Lucent pipelines (20, 50 75 or even 130), CISCO, Nortel, Pairgain. Every brand has xdsl line so just make up ur mind and pick one.

Another possibility you might want to consider is to use spread-spectrum wireless networking products. You'd only need one access point since all your locations are within a 2 KM radius. Check out products from suppliers like www.wilan.com, www.breezecom.com, etc.. The 900 MHz and 2.4 GHz units would work well for your short-range requirements.

Your best bet is to wireless if L.O.S. is not an issue.
