@NewtronStar:
It was the crosstalk effect after the DSLAM update, Upstream SNRM back to normal same as connection speed after turning off modem and then back on again this evening
Accept that after a DSLAM outage for whatever reason it's going to be a race on re-instatement between all the serviced devices to attain synch and some form of pecking order is bound to be established, however, as I was reporting on 3 different lines on 3 different DSLAM's I thought that the S/W change may have been a factor in the increased US synch rates recorded, most likely not the case.
I won't be forcing re-synch's on the lines as in all cases there have been speed improvements and have not noted any significant increase in error rates, DLM will intervene if deemed necessary and yes, it's most likely that the synch speeds would return to pre-DSLAM outage state if/when this occurs or the lines re-synch for whatever reason.
@jelv:
The BTw Performance Tester URL I have always used is:
http://www.speedtest.btwholesale.com/I always run this with Pale Moon browser in view of the known issue with Firefox, my normal browser.
Until recently, this has offered the option, after initial speed test, to proceed to "Further Diagnostics", enter phone number and obtain line BRAS profiles, no longer the case.
Have tried the URL you provided, yes it does work but as NewtronStar has said the reported speeds are completely incorrect with FF browser and the test won't complete with Pale Moon browser, advises that a temporary IP & domain name change are required to complete.
