I saw the 10-minute outage with what, we presume, was the upgrade of the DSLAM to support G.INP.
However, my modem (Huawei HG612, on firmware new enough to support G.INP) came back up with standard settings - which, for me, meant no DLM intervention. Previous to this, the line ran at around 60 ES's per day, so was well under any DLM intervention point (in fact, probably low enough to get DLM to reduce/remove any intervention if there were any). After the resync, the ES rate was unchanged...
The line eventually underwent an automatic resync around 3 weeks later, with a regular outage of around 30 seconds. This activated G.INP on the line; sync speeds stayed at 80/20, and latency stayed roughly the same. The attainable speed jumped by around 6/2, and the ES's disappeared.
My only conclusions are:
- Upgrade of the cab only marks the starting point at which G.INP may be activated on a line, but does not force it.
- Activation of G.INP is coming to every line; if not every line, it must be nearly every one.
