Chorus / Telecom Cabinetisation

Telecom have started to install Cabinets in our area to reduce the Local Loop distance. This is to increase ADSL and VDSL line speeds. We are not able to get reliable ADSL2+ in our area due to the distance to the Howick (HCK) Exchange. I have hard set the router to connect at itu-dmt (original ADSL) as it tries to connect at ADSL2+ however the connection is flaky and drops out every hour or so.

According to the Chorus website we will be migrated to the new HCK/AF Cabinet around 7/12/2010.

This blog is to compare the before and after ADSL connection speeds. Hopefully we should get a major speed increase as the new cabinet will not be that far away. I will update this blog again once we have been cutover.


Edit: Its now post cabinetisation and we now have been upgraded. As you can see below we have had a vast improvement in speed. The line is stable which also helps. It didn’t go without it's dramas though, We lost Internet for just more than 24 hours due to a DSLAM (the equipment in the cabinet) was miss configured for my ISP. This website, Shelly Park weather station and my emails when down. The router could receive the ADSL carrier and show the new line rate however it would not establish a PPP connection. Thanks to Maxnet who kept the pressure on Telecom to get the issue resolved.


Below is a dump from our Cisco 877 ADSL2+ capable router (BEFORE):

As you can see the router connects at 5600kbps download and 832kpbs upload.
