Re: VM on Watchdog
qas they extorniote that you have to go from a £26 inc vat package to £40 exc vat to be able to get the £5 addon. Plus £5 per month for an ip is also expensive.
Also DLM doesnt cope with anything, it reacts after the event. It can over react, it can under react. Not to mention DLM requires a resync to work which in itself causes an outage to the user.
I think to say SRA cant cope with large swings you talking to the wrong guy, you talking to someone who had severe swings of noise bursts to the point its the largest tbb had ever seen on a connection, eg. BT's DLM would put my line on its most conservative profile of 15db and interleaving and the noise still took out my connection, plus for the rest of the day when the noise wasnt there my line was severely capped.
SRA will throttle your connection live with 'no' drop, then immediatly when the noise stops the throttle is gone again with no outage. DLM doesnt even come close to SRA. DLM I see as just a cost cutting measure, to reduce man hours by the isp in manually configuring connections. BE and ukonline got alot of their business from people just wanting to escape DLM. This is why I am so dissapointed it still exists as its just a messy hack.
SRA can stick to a target noise margin or work based on error count. Remember the idea of SRA is to stop interruptions to the connection, DLM cannot work without an interruption. I went from 10+ disconnections a week to having over a year uptime in my adsl days with SRA.
The downside of SRA is its apparently hard to get working right, BE attempted it twice and aborted both times. Even on ukonline it only worked with a small set of routers. But when it works DLM doesnt even get close.
Hopefully tho my line wont have issues and DLM will stay quiet without flip flopping.
