Pseudo always-on is of course possible with ISDN.

Either The ISP can dial your router direct - or it can dial, your router
refuses the call but recognises the CID and dials straight back.

BUT. it really requires several things to make it work. Static IP
addresses,
the ISP to "know" your phone number, and hardware to make the
outgoing
calls.. All of which make it impractical on a national scale. Remember Most
ISPs that offer dial-in access do so via someone else's (BT!) dial
infrastructure via 1 fat pipe and dont actually have their own dial-out/in
hardware at all. It requires resonable control of the configuration either
end aswell.

It can be done for specific groups (Corporates for example) but not easily
(i.e. cheaply) at the consumer level. In fact my connection to work is
pseudo always-on in this sense, the connection can be initiated from either
side but they dial me back so I dont have to pick up the tab.

The Mid-band trick was allegedly to use the B (signalling) channel but
again
they seem to have had problems scaling it for a national consumer
application.

Why it was annouced before testing was obviously complete is the bit that
baffles me :-(

Trust me Mark - it will.  Somehow, and maybe at a price, but it will
come, misquoting Field of Dreams.

When Midband works as the liars originally said it would, it'll be
close enough for most folks not to notice the difference.  Its a tad
frustrating.  An ex-ISP operative of my aquaintence had pseudo-always-
on internet using ISDN back in the twentieth, but, and its a big but,
you needed to pick up the call charges.  The software to do this was
in routers years ago.  What Midband offers is a price cap.  So where
have BT screwed up this time.....?
