this doesnt bode well for us on eci cabs.
Retransmission can operate in both downstream and upstream channels simultaneously, although ECI equipment (either modems or DSLAMS) doesn’t currently support upstream retransmission.
* Any infrastructure that doesn’t support retransmission in the upstream will default to interleaving, increasing upstream latency by approx. 8ms.
I assume there is a reason g.inp cannot be one way only just on the downstream? so upstream left on fast path.
IF so openreach should leave fast path as the default on ECI cabinets and only use g.inp on unstable lines.
Kitz I suspected this issue would affect ECI cabs and it looks like I am right based on the ispreview article.
I also wonder how many isp's will tell end users this, and we only been made aware due to someone leaking it to ispreview.
I might email joe garner myself to stress they shouldnt replace fast path with this junk, only interleaving.
