We seem to be having problems with setting up bonding 2 SHDSL 1Mb lines

using a CISCO1721 w/ WIC-SHDSL-V2. But it doesn't seem to be working.
When we enable both the lines, the service just drops. Our ISP is
Freedom to Surf (F2S) and BT is the wholesale provider. We have spoken
to F2S and they say that some of the BT exchanges are not set up to
support DSL MLPPP. Does anyone have similar experiences or ideas for a
solution?


any thoughts would be grateful

We have had exactly that and opened a TAC case. Normally if the lines are
ordered at the same time they go through the same DSLAM etc and timing is
OK, but in our case the timing fails.

Solution was to avoid MLPPP and uase either multi Home NAT or load sharing
with 2 routes

Well it seems finally Freedom 2 Surf have managed to provide us with 2
x 1Mbs lines bundled together. After plenty of emails/phone calls to
and fro them and BT have made the changes to the DSLAM and their
network. WEYHEY!!
