In 2009 Bell's infrastructure did not support ADSL2+, while the modems NCF sold then, the Thompson SpeedTouch 516 and 585s, did. Because the modems defaulted to ADSL2+ and not the ADSL1 then in use on Bell's networks the modems would not connect. To fix this problem a number of modems shipped at that time were configured by NCF to force them into ADSL1 mode, which solved the problem. Now that Bell's infrastructure requires ADSL2+ for 15 Mb/s service these modems that were configured that way will not work with 15 Mb/s service unless reconfigured.

The configuration cannot be fixed by doing a factory reset, instead it must be done by Telnet into the modem and changing it via command line. Fortunately this is easy to do.

Accessing Telnet

Linux and Mac

On Linux operating systems you can access telnet by opening a terminal and typing in "telnet" at the prompt.


On Windows XP and Vista operating systems telnet can be accessed by opening "run" and the "cmd" command and entering telnet.

In Windows 7 and 8 you can bring up the command line by entering "cmd" in the search bar.

In any version of Windows you can also run telnet by installing and using the PuTTY free software application.

Configuring the 516 or 585 v7 modem for ADSL2+

The commands are:


User: admin/Administrator
Pass: <your dsl password>

xdsl debug multimode config=t1.413issue2+g992.1_annex_a+g992.3_annex_a+g992.3_annex_l+g992.3_annex_m+g992.5_annex_a+g992.5_annex_m

That "xdsl..." is a single command, so in copy and pasting be careful to copy the entire line without any carriage returns, which would compromise the command.

Configuring the 585 v6 modem for ADSL2+

The commands are:


User: admin/Administrator
Pass: <your dsl password>

adsl config xdsltype = adsl2+

ADSL configuration:

detect-lop = enabled
syslog = disabled

and then to confirm:

adsl info

which should return a result similar to:

Modemstate : Up
xDSL Type : ADSL2+
Bandwidth (Down/Up - kbit/s) : 15455/797
Uptime (days hh:mm:ss) : 0 days, 0:01:11

and then
