It has taken me far less time than expected to get this running on FTTC - inspite of not using the web interface
There is a noticeable speed increase over the BT Openreach Huawei modem. The estimated download speed from the BT Wholesale DSL Checker was 30.9Mbps with upload at 5.9Mbps.
At the moment, before the training period is up, www.speedtest.net shows downloads at 36.91Mbps and uploads at 7.63Mbps.
Sync is currently at 39719kbps down and 8855kbps up but the Cisco shows the line is capable of even faster connections down;
> Attainable Rate: 45876 kbits/s (down) 8851 kbits/s (up)
It will be interesting to see if the link gets anywhere near that as the service is an "up to 80" from Zen.
We're running with a block of 8 IP addresses and no NAT on the router as that will be handled by a dedicated firewall.
I am absolutely not a Cisco expert but if anyone needs a config for a similar install I am happy to share.
