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