Interleaving

Turning interleaving off will it help improve the sync, or does it only help lower pings?.

Re: Interleaving

There are a some mostly older type router/modem units which when used on an interleaved line do restrict the sync to a lower value.
This is due to complex technical issues of the chipset and processors within them and what differing international ADSL standards they are capable of working to.
One such I personally know of is the BT Voyager 210 - this has a max sync on the 'up to 8Mb service' (ADSLmax) of 8096kbps when the line is interleaved compared to 8128kbps as the max possible normally quoted. When used on a Fast Path line it will do 8128kbps.
When broadband first came out BT stated that the max possible sync on an interleaved line was 7616kbps, but obviously since then router/modem units came out with the ability in their processing power to get round the problem of the data overheads created by the interleaving/error correcting process on the line.

Re: Interleaving

So i guess having it on doesn't do nothing to the sync, it only makes the pings higher.

Hi tomxlisa,
Yes there's not a great deal of impact on the sync but your pings are likely to be a bit higher. Also with regard to your PM, your 10 day training period should finish on the 13th.

Re: Interleaving

Turning interleaving off will improve the sync if your router supports Trellis Coded Modulation.
