I found a previous post I made of the registry settings a

Windows 9x:
\HKLM\System\CurrentControlSet\Services\Class\Net\000x
Windows NT:
\HKLM\System\CurrentControlSet\Services\NTSPPPOE\Parameters
Windows 2000:
\HKLM\System\CurrentControlSet\Control\Class\{xxx}\000x

Where 000x is the enumeration of the NTS PPPoE Adapter.
And {xxx} is the Object Identifier for the Network group on Win2000.

set LCPEchoTimeout to be something like 100 (you haev to send the LCP every
14 secs of below on telecom's network)

LcpEchoTimeout
This parameter defines the amount of time between LCP Echo Requests sent out
by the client. This parameter is defined in PC timer tick counts. For
instance if you need a value of say 3 seconds you have to set the value to
55 (3000/55 ~= 55) . If this parameter is not defined in the registry the
default value for this parameter is set to 30 seconds.

LcpEchoRetries
This parameter defines the amount of retries the client will attempt for
unacknowledged LCP Echo Request. If this parameter is not defined in the
registry the default value for this parameter is set to 3. If this parameter
is set to value of 0 the LCP Echo mechanism from the client is disabled.

LcpMRU
This parameter is used as a part of LCP Configure Request from the client to
notify the server of it MRU size. This is arbitrary number and has no
correlation with MaxFrameSize parameter already present in the registry.
This is just used for LCP negotiation and is not conveyed to protocol stack
etc."
