A1) Yes but they won't do it because potentially it affects their load balancing on your cable segment/node so only Level2/Networks or possibly retentions will do it, if you know who specifically to talk to (which of course you won't).

A2) Any Leve1 (except offshore) can inform you or depending on the network log/SHub model then some error stanza's will contain the CMTS-mac
address from which the 3 high order octets will reveal the NIC type for the CMTS which can be resolved to CMTS type. Reverse DNS Host address will also yield a clue.

A3) First off Level1 callcentre (except offshore may iinvolve some time wasting), otherwise UK Retentions (Thinking of Leaving us option) 150 option 5-4? during office hours have more flexibility if you're negotiating a degraded service on that basis.

Go to the top of the page here and click on connection.

Oops my bad - should have read the question properly! :( Once the node is configured to CMTS they only have some latitude excluding some CM's from load balancing groups and/or balancing across different mac domains but not on different CMTS unless the whole node is switched (probably easier for the OP to move house? :dunce: ). Cheers again for correction.

When your speed was 'upgraded' all that happened was a new config file was sent to your SH. Nothing else, No change of CTMS, No nothing.

There is no possible place your cable could go via a different route to your neighbour to the CTMS.

Both cables will go via the same ducting to the cabinet and the same way to the CTMS.

Thanks.

Good to know it is possible even if it will be a battle to find the right person and then persuade them to revert it.

I am happy that they are working to fix the over utilisation but am disappointed that they upgraded my broadband when they knew it was likely to cause a degradation in service. It's also no good being given a fix date which isn't a fix date.

If there is nothing they can do I will need to look to terminate the contract, though I have little desire to do this after 15 years of generally good service.

Edit: didn't see the extra page!!





So what the faults guy told me about moving to another CMTS when my speed was 'upgraded' will be incorrect? Or I could have misinterpreted what he said.

Do you have any recommended reading so that I can understand a bit more about how the VM cable network works? Or would you be able to give me a brief outline of the route a cable connection takes to the CMTS and the possible places it could take a different route compared to a neighbour?

The only way it would have been put onto a new CMTS port is if any type of reseg work occurred beforehand. If it was put onto a new CMTS it would have been done anyway as part of the E6000 upgrade nothing to do with speeds.

The only way it would take a different route was if you were on the nodal area boundary. I have been on a couple of jobs where the cable has been pulled to the pit to the right of the house rather than left, which was actually fed from a different node.

Basically the feed into your house is RF. Your signal will travel through various bits of coax and through a couple of amps, then back to a fibre node. The fibres run back to the headend/hub site, goes through various splits and conversions to back to RF and it ends up at the CMTS

There are some diagrams and explanation in this thread:

Whether you're on an Arris E6000 CMTS now, or still on a Motorola or Cisco, you can find out by googling your CMTS MAC (see your hub stats if you have a hub 3) as has already been suggested.
