Woof, bow-wow, grrrrr....
Some un-named person once sent me email suggesting that anything more
than a single sentence is too long and complicated. So, here's DSL in
one sentence.
DSL seperates the low POTS frequencies, from the higher DSL data
frequencies, which are run through an adaptive equalizer, echo
canceler, and directional isolators, upon which an ATM permanent
virtual circuit is established between the ADSL modem/bridge and the
telco DSLAM, which is then fed to the ISP via a different ATM
permanent virtual circuit, terminating in the ISP's Redback ATM
router, where both the router and the ADSL modem/bridge extract the
ecapsulated TCP/IP packets, and therefore deliver IP packets between
the ISP and the customer.
See? Isn't that simpler?
