richms: Ok, well will those of us not still on ATM ever get to see the end of ATM as part of the customer side connection?


Most EUBA0 connections will still rely on PPPoA as most people do not have modems which support PPPoE.

 
 


I have not come across a modem that does not support PPPoE, so I think most people will have modems that support this no problem. Catch being they will all be set to PPPoA, so you can't just switch on PPPoE only, as everybodies conection would stop working.
You either need to do this on request (as you suggest), or have legacy PPPoA support at the DSLAM (which Vodafone Red network does).
  


Sorry I was getting confused with the added features needed for EUBA40/90/180. EUBA0 PPPoE should be ok for almost all current CPE.

If you're connected to an older ATM connected DSLAM then you have to use PPPoA as these types of DSLAMs are connected via ATM only. The newer Alcatel ISAMs are Ethernet connected.

EUBA (on the ISAM only) gives ISPs the option of going IPoE

Most ISPs stick with PPPoA to the customer modem because it's simplest and works no matter what DSLAM you are connected to. Imagine having to ask your customers to change their modem settings just because they've been cabinetised or because they've moved house?

PenultimateHop: What's the problem? PPPoA is more efficient than PPPoEoA, which is what you end up with since ADSL(2) is inherently ATM based.


For the average user: none
For the power user: bridging

It's tough to bridge PPPoA connections, you need to use hacks like half bridge/ip extension/proxy arp with dhcp spoofing or that Draytek Vigor with PPPoA to PPPoE translation in order to bridge basic ADSL modem with a more advanced router or firewall.

There are very few all in one modem/routers that have the kind of features you can get on pfsense, monowall, DD-WRT, Tomato etc.. most notably usage/traffic accounting.

It is very easy to make use of pfSense even if you are unable to fully bridge the PPPoA. Personally I see no problem with the current setup.

Only with double NAT or NAT + DMZ both of which tend to cause problems for gaming.

Good ADSL modems support RIP/Custom routes, my Linksys WAG200 only connects to my Linux box (via 192.168.0.0/24) which routes without NAT to everything else via various other subnets (n.b. I don't use RIP because I had issues, and haven't tried again recently).  I'd much prefer to just use PPPoE to de-complicate everything and do things my way.

As far as EUBA, my understanding is only upgraded Exchanges can get EUBA and at least one ISP is doing PPPoA on the 'traditional' circuit, and PPPoE on 0/110.  (Can't find the URL right now sorry).
