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

[Darren Moss]

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...
