Check out Greybar (can't find an online presence). Plenum (fire retardant) cable can be bought for $60-70 for 1000ft. A definent must if you're looking at running power over ethernet. Good powered networking gear (Cisco Catalyst switches) will power down the port if they try and draw too many amps (see it happen when bad runs were causing power loss along the way). I'd hate to see what happens with cheaper gear.
True phone lines aren't a problem, however 10Base-T is not 100Base-TX. Furthermore, when he upgrades to 1000Base-TX NICs, he'll be totally out of luck if he goes out of spec or has the slightest interference. AC power can be a big problem.
Don't come near power lines and even more importantly fluorescent lights. Anything with a large power draw or heat source (HVAC units). Another thing to consider is that for the most part you might not have a problem, but when you run high amp items, you might notice problems if you're close. Items like microwave ovens, toaster ovens, and whereever you'd plug in a vacuum (huge amp draw).
As I support someone intelligent users, we allow the files through, but modify the extension to add DEFANGED-, so that they can scan and rename them if they like.

It's really not that hard to find info. Get Halabi's Internet Routing Architectures book to start with the fundamentals. Then find LISTSERVs for your local IPSs. They're out there, you just have to look. Here are some generic vendor-specific Provider lists: http://puck.nether.net/lists/
To start with, I'd connect with UUNET, as they're everywhere worldwide, easy to work with, and very professional. Once you've been through the process one time, you can work your way through less helpful ISPs.
To "prove" you need the hosts, you just come up with a BS network diagram and list of hosts. It's not hard, it's just an ethical problem.
ISPs ignore smaller than/19 out of classic Class A and B address space. Since Class C space is by its very nature/24 blocks, they cannot filter that without cutting off a large portion of the internet. Since 63/8 and 64/8 were given back, those also are not filtered beyond/24 for any clueful ISP.
The bulk of the IPs you'll get are from classic Class C space, 63/8, or 64/8. Providers know this, and if you tell them you want blocks to multi-home with, they'll assign them from one of those ranges.
You AC trolling twit. He provided an excellent link to a FAQ of written by one of the top internet backbone architects (Freedman is on of the top brains for Akamai's routing infrastructure, and an investor/advisor for Havenco). Anyone who doesn't know the terms or how to do this should just look into that (which is where the original poster should have gone).
RAM is still very much an issue. Every single router for a decent provider has to carry a full BGP table. That's 128mb, minimum. Which, yes, you can get RAM cheap, but not Cisco-approved RAM (and, yes, Cisco now only supports Cisco-approved RAM if you call into TAC).
BGP4 route tables are transmitted once when a router comes online. So long as things are stable and links aren't flapping, the routes aren't retransmitted.
As nice as it is to have Provider Independant IP Space, as you've found out it's virtually impossible to get without paying through the nose (you can just BS how many hosts you have, if you want to fork over the cash to pay US$2,500/year for a/20 block from ARIN here in the USA). Then there are less clueful orginizations that don't even know they have some, because the current IT staff didn't get along with their predecesor (for instance this block I found for my own local City).
However, it's not required to multihome. Really what you require to multihome is an Autonomous System Number (ASN) and a/24 block from either traditional Class C space, or the 63/8 or 64/8 Class A blocks that were returned a bit ago. No one with a clue should be filtering a/24 from either location.
The biggest downside to using your upstream providers IP space is that it pins you to a single ISP as you must use their IP space, and leaving them requires renumbering (but can be done without downtime within a reasonable transition timeframe of a few days). What we did was pick the largest ISP out there (UUNET), and then one of the top 10 (Sprint) and use both IP space (although we could have chosen to only use UUNET's). We use both provider's IP space on any important box (email, mainly) so that if we were to disconnect from one ISP (not likely), we only have to remove their IPs from our DNS, and the other IPS's IPs are already there and live (plus it gets around odd local routing problems outside of our control, where one remote site can reach one ISP but not the other).
We announce both blocks out both ISPs (to announce UUNET's blocks out Sprint and have them come back the shortest route, we had to get UUNET to "punch a hole" in their larger block and announce the smaller block we had so that both UUNET and Sprint would be announcing equally specific blocks for us... same is true of Sprint announcing their own assignment to us more specifically so they'll route to Sprint or UUNET, as if we only announcing the smaller block out UUNET, then all traffic would go that way unless our UUNET connection was down).
You don't need a huge router to be multihomed. Even a 2501 would work (as you just take default routes announcements from both ISPs, with the point being to advertise out your own blocks). If you want to take full routes from two ISPs, a 2650 with 128mb of RAM will work fine. If you want to take defaults + ISP-direct-customers, a 2610 with 64mb of RAM will work (it handles ISP-direct-customers from Sprint and UUNET just fine for us).
Lastly, never forget that site redundancy is just as important as internet redundancy. If a backhoe takes out the fiber or copper pairs going to your neck of the woods, more than likely it'll be both ISPs.
Normally I'd never mention my certs, but here they're relevent:
I'm a CCNP (next step past CCNA) and CCDP (next step past CCDA). I've been working for an IT Consulting/Integrater firm for 4 years (help desk positions 3 years before), and we also have our own little ISP on the side. I've worked with all the top 10 ISPs (and plenty of the Tier2/Tier3 folks), and set up a couple hundred of multihomed sites, so I'm not just quoting what I read in a book somewhere.
Someone posted very early on how to get the file without having to download it each time (faking client as Quicktime). Mirror of the files out so far (limited to 3 anonymous users until after 7pm PST):
Funny how this somewhat lacking story gets approved, but yet my post with some actual substance, was rejected last week.
Anyway, here's was my original post:
I was sitting around last night and came up a pipe dream of sharing my ADSL with the rest of my low-income neighbors. I'd like some practical feedback from those of you with experience with Linksys gear (or advise another economical brand, but they seem to be pretty decent as far as low-end 5 port switches and also routers).
My main concern is being able to control any sort of topology loops (STP is used in standard bridging/switching, what about wireless?). How can I control which Linksys acting as a Bridge connects to which other bridges?
Any other design concerns in my little pilot test? What about scaling this to homes beyond... how many Bridges can be connected in series before problems occur?
It all depends on the codecs they run. g.729a can get voice down to 12kbps with another 12kbps of protocol overhead (if you're running frame relay with FRF.11 you can use compressed TCP headers and keep it about 16kbps). Vast improvement over g.711 64kbps standard PSTN calls use.
Cisco's way ahead of the game on all of this. Their 79x0 line of phones with CallManager on the backend rocks. Granted, it's not as bloated as the AT&T phone looks to be, but it's got XML and basic graphics capabilities built-in.
The also have a "soft phone" as well that runs great when you're not near you regular desk phone (so you can pick up calls remotely).
Someone was mentioning fear of tapping VoIP packets. Why even go that far? Until everything is on VoIP, you still need to have a connection to the PSTN, and that's where they'll be tapping things for a long while. If you're concerned about sniffing VoIP packets, run a VPN with encryption back to your office's PSTN... of course they can still use a classic wiretap once you hit the office PRI and on to the PSTN.
I'd like to see a pricetag on these phones and the backend servers they're talking about. Cisco's solution isn't cheap, and you know the telco's aren't going to be any better priced. Of course, they want you hooked up to their servers and paying monthly fees, not taking a free ride.
I like my local DJs, as they usually respond to email within an hour or so (even if they don't use a spell-checker *g*):
