In the case described above then your PSTN line is plumbed into a
DSLAM/MSAN if it is in sycn but it sounds like it hasn't been
provisioned correctly by BT Wholesale. If your CPE is sending out PPP
discovery packets (be it PPPoA or PPPoE) and getting no response, and
not receiving any incomming PPP packets, something is wrong in BT
land. Your VAR/Wholesaler needs to speak with BT Wholesale support,
your CPE should be asked to authenticate after LCP sends out a CONFREQ
packet and this is picked up by the BRAS.
