Re: PPPoE session from Montreal terminating in Toronto???
The modem is the one that came with the service Aztech 605EU.
Sounds like a DSLAM - modem incompatibility that gives the strange readings. |

| Your modem is good, actually.
I tried many other modems on same scenario(My DSL) and some (old ones) don't work at all or hardly sync at 1-2M
The Bell technician's yellow diagnostics tool didn't sync at all, either.
Otherwise, my and your DSL is considered as good ones 
And they are!
Thanks. |

In fact, since you sound like you are able to do it, could you please post the more complete stats:
telnet, then:
cat /proc/*/*m_s*
Thanks! |

You are the first to confirm what looks like a way for Aztech modem users to identity IKNS DSLAM devices.
Thank you! |

| And now explain IKNS... I've seen IKNS mentioned in the forum a couple of times but I don't know of any DSLAM called IKNS, although I only know Alcatel and Ericsson so I might be lost. |

| It should be some abbreviation but the meaning is type (brand) of CO equipment used in DSL . I think, it is Canadian made
For some reason, it behaves different than classic ones and creates some support troubles, as you see.
I am trying to find any official information on that as many people do.
On Bell site I've seen discussions where they claim that all IKNS-reported problems were minor and fixable by other means (something like this).
In two words:
The user is very close to CO but upstream is not synchronizing at full 800 and/or NM is shown very low, say 6dB.
Some strange interleave modem reporting on AL1 profiles and/or higher pings.
Unfortunately, 70% of cases I open recently seem to be in this category.
Best regards.
