FURTHER INFO: Poster posting about low upstream ADSL

Hi,

To the poster (and anyone else / others) who was mentioning about problems
with VoIP due to low upstream bandwidth on their ADSL.

I happened to notice recently again that in fact the minimum upstream
bandwidth on ADSL services is actually 64 kbp/s. This suggests to me that
you are actually having problems due to something other than "line length"
per se.

I.e. other a very high error rate effectively reducing throughput or more
likely some other issue (either on your side - e.g. could be any of a large
range of factors, filters, modem, software, hardware, configuration; or on
your ISP's side - bandwidth / capacity limits, contention, etc.).

Thus, I would definitely check with your ISP - I think the problem may well
lie their. However, in short, it should not really be an issue of bandwidth
per se (although even the minimum ADSL rate of 64 kbp/s is still a little to
low / to low for some [including a number of the mainstream] codecs).
Further, if this is "effective" reduced bandwidth / throughput due to errors
then you should notice and would be very likely to experience other
anomalies, problems or other obvious manifestations of abnormality when
using VoIP - e.g. audio dropping out, corruption, etc. Hence, if this is an
error related issue, it may be something that is not "line related" or
bandwidth related "per se".

Hope this helps.

Best wishes,

Hi,

Not sure if I totally followed you their.

The minimum is: 64 kbp/s
Yours: 288 kbp/s
High(s): 844 kbp/s

I believe 256 kbp/s is the standard for the fixed speed 512, 1mb and 2mb
services (or 288 kbp/s synch speed - I would imagine).

Thanks for your message. Nice upload speed
