[AusNOG] Anyone run across any incompatibilities between Telstra's NEC DSLAM's and Cisco ADSL routers?

[Bill Walker]

It would certainly be worth upgrading the IOS to the latest version
in case its a bug. I know we had issues when Telecom moved to ADSL2 in
NZ due to a driver issue for the DSL chipset in 877's. 

Cheers, 

Bill

Hi Justin,


We have more than 100 Cisco 87x units out there and they all work fine
with no issues. The bulk of them are on Telstra Business Broadband
connections. 

We *did* have an issue with the first release of Cisco
857 series routers, which was related to a firmware problem. Cisco was
engaged, a firmware update was provided, and Telstra agreed to upgrade
all our clients running the 857 series units to the new firmware. 

This
resolved an issue where the DSL service would reset due to attentuation
issue in the firmware, however the router would never reconnect. 

We
were sometimes able to force a service reconnect by tearing down the
tunnel between Telstra and the client site, however the best way to fix
was to hard reset the router at each site, which was very painful and
ended up consuming a full time person on our helpdesk to ring everyone
and manage the restarts. 

So to answer your question, on the 87x
routers we have no issues, but on the 857 series units we had many
issues until the firmware was upgraded. 

Hope this helps. 

Cheers.

Hi, 

Seen something similar in Kalgoorlie WA about 5-6 years
ago. 

A provider had rolled out about 30-40 Cisco 8xx's, unfortunately
I didn't know what DSLAM gear was in the exchanges but they quickly had
us run around and deploy Dlink ADSL routers& return the cisco's. 


Later down the track the provider installed its own DSLAM's so I never
found out the cause of the problem.  

Possibly it was just a large cock
up on the providers behalf as I had plenty of other customers running on
Telstra based DSLAM equipment with Cisco's at the time and the provider
had not applied a firmware update to the DSL interface. 

It was just
really odd though that they replaced the lot with DLINK's and then
rolled out their own DSLAM's.

Hi guys (&gals!) 

Just wondering if
anyone else has run across issues with ADSL reliability between
Telstra's NEC DSLAM's and Cisco ADSL routers? 

Got a client down in
Henderson WA who's having all sorts of reliability issues and Telstra
have come back and advised that the Cisco ADSL router (877) is
conflicting with the NEC gear in the Exchange… 

Personally, just sounds
like Telstra's trying to fob off the customer to me (given, if someone
asked me for a reliable rock-solid ADSL router, I'd point them to the
877 (or above)) but just thought I'd double check before going to the
hassle of configuring a non-cisco device for the site… 

Off-list
responses are probably better and I'll summarise to the list if it's
suitable to do so…
