Hi,
at a presentation, we received information from a german Telekom person, and confirmed from a Cisco person also present, that a nationwide DSLAM update (though progressing only slowly) will cause problems with all current 836 routers, preventing them from being able to connect. As this DSLAM update is done to extend the range for the DSL connections, it will be rolled out first in areas where the availability of DSL is low at the moment.
Anyway, the Cisco guy present said it was a problem of the 836, and that a ticket has been opened, no fix available yet.
I have checked with our cisco reseller, as well as a Cisco contact, both haven't heard of that problem yet.
As 836 routers are the main routers we use for our customers (and are and have been recommending due to stability and quality), we are a bit worried of the day when some of our main customer regions are upgraded and suddenly several dozens of customers are left without Internet ...
Has anybody else heard of this, and could even name the ticket# under which this is being worked on by Cisco, as we would like to keep an eye on any progress and especially fixes ...
Thanks, -gg
