That volume of re-syncs wouldn't result in DLM taking any action - on the "standard" profile, which is applied to all our FTTC orders, DLM wouldn't take any action based on re-syncs unless it sees around 10 or more within a 48 hour period. If previously your connection has re-sync'd more then DLM has likely applied action to prevent that - including interleaving - and the low level of disconnections you've seen are just typical xDSL operation.
Alternatively, errors, rather than re-syncs, occurring on the line could by why DLM has applied interleaving.
The "standard" profile is the least aggressive DLM profile available, so therefore least-likely to apply interleaving, so if it's applied there aren't any options to address it.
Interleaving can not be disabled on a line, as Openreach don't provide any facility for any ISP to do this. It can be removed from a line through an engineer visit, but that would only occur if a fault was the cause of it being applied (and it wasn't automatically being removed when it should have). If there's no fault condition the engineer visit would be chargeable. We are attempting to get answers from Openreach on why this isn't a customisable option (it is on ADSL services) and if there is no technical limitation on this will push to get this made available.
