[AusNOG] Soul DDFM Services

[Nathan Sullivan]

Yea I had a play with a Powertel SHDSL link (I believe they used the term
SHDSL.Bis) running at 10M/10M over 6 copper pairs. Was at about 3.5Km from
the exchange, ran very nicely :) The Hatteras boxes had 2 RJ45 ports,
allowing up to 8 pairs total. On shorter lines they claim the speeds you
said (5.7Mbps) and they usually set it up in an N+1 arrangement with copper
to allow for a pair going dead (hello techs who steal pairs with no
dialtones :P happened at least twice over a 6-12mth period). When Powertels
contractors came out they preterminated all 8 pairs/2 RJ45s from the
Hatteras back to a Krone disconnect module at the MDF, so additional pairs
could be connected as required to ramp up the link speed. We saw very little
outages when pairs were added or dropped, it aggregated them quite well :)
Since it was a Layer2 P-to-P service we just saw 2 Ethernet links either end
really, nothing much more to it. Could also see each SHDSL lines sync lights
on the back of the Hatteras if there were any issues.
