ADSL upload speed increase in June

May 29, 2008

We previously covered the proposed Telkom ADSL upload speed increase trial in our post in February, news posted today confirms that the ADSL line speed on the 4 Mb/s ADSL service will be increased to an upload speed of 512 kbps from the end of June. This is a marginal increase from the current 384 kbps, but will allow for better throughput for 2 way services like VOIP and ADSL VPN.

So, using a VOIP example:

If you use the G729a VOIP codec (40kbps per voice channel) you will be able to have 12 simultaneous voice channels, previously you could only engage 9 channels safely with an upload speed of 384 kbps. So for no extra cost you will now get an extra 3!

ADSL 4Mbps service = 384Kbps upload. (Current)
to
ADSL 4Mbps service = 512Kbps upload. (end June)
