As already reported Openreach commenced roll-out of G.INP to their ECI estate in March 2016
We have been following progress of the roll-out and for the vast majority of lines, this appears to have been successful with most users have seen an increase in their sync rates.
However, it became apparent a few days ago that some lines were seeing behaviour that looks suspiciously like the ECI modem - Issue 1 problem
. Affected lines are able to sync but not get a valid PPP session.
Openreach have identified those lines which they suspect could be susceptible to this particular fault and as a precaution have suspended roll-out of g.inp for those affected lines only.
Retransmission has also been removed from any lines which have an increased risk of developing this fault, regardless if they were affected or not. Discussion re: Suspension of G.INP on ECI cabs for affected lines
