"routers" and PPP

I`ve noticed that for user,pass they seem to use a username with an
@ like

(E-Mail Removed)

is that always the case?
anybody know why?

I am in the UK, the ones I Have seen have all been PPPoA. Is it only
PPPoA that have that?

With some USB modems the PPP is done in windows. Is that still
PPPoA ?
(I am guessing so, since isn`t A for ATM , which is to do with the
service provider)

Yet This link here
http://www.udel.edu/topics/connect/ppp/XP/index.html
shows a windows screen that suggests that USB modems use PPPoE, and
that the username does not have an @.
I can guess that they use PPPoA in UK, and PPPoE in america.

Is it also the case that PPPoA tends to use an @, and PPPoE tends not
to ?

Is there a name for a device whose function is PPP? I am guessing
not. I guess it is another function they bundle into the device
called a "home router". I know with dial up modems it is always
windows that does it. And I have heard that a router can be put in
bridge mode and then PPP can be done in windows. Is that right?

Yep. That's the way a RADIUS server wants to see user names. Most
ISP's have multiple domains running on the same system. Each domain
could have duplicated user names. For example:
(E-Mail Removed)
(E-Mail Removed)
(E-Mail Removed)
are all different accounts. If it were just "jeffl", there would be
no way for the RADIUS server to distinguish between them.

No. PPPoE also uses the same system. Not all DSL systems use PPPoE
or PPPoA. However, the one's that do usually require some form of
authentication.

Duh. I don't know. This is a wireless newsgroup and not a DSL
newsgroup. You would probably get a better answer if you asked in a
DSL specific newsgroup.

That's for a dialup connection to a university. The university has
only one domain. All the user names would end in the same domain name
(udel.edu). Therfore, all users names would need to be unique for
authentication. Usually, universities use the student or instructor
ID number instead of potentially duplicated names.

Dunno. Your questions has nothing to do with wireless. Try asking in
a DSL newsgroup.
