i can see the one i am connected too out my front window.it is about 20m away as the seagull flies

How do you know it hasn't been overhauled? Some cabs only require a few hours to make changes inside, others may take a little longer.

is there downtime involved in this?

Peter_ · 12-01-2012, 19:17

The average downtime is around 4 hours but it can be offline from 8am to 6pm.

They don't have to be overhauled if they're performing OK

I'm guessing customers get warned before hand ?

is the cab upgrades part of this speed upgrade or separate, can it function properly without the cabs being upgrades or will each area get upgraded cabs before the speed goes through?

Sephiroth · 12-01-2012, 19:47

The cabs (apart from optical nodes) house amplifiers. These amplifiers are hooked up to the 48 or 16 (according to cab size) local users and the next cab further away from the optical node. Some of these amps are 15 or more years old and are thus potentially phutted.

The cabhave to be done in daylight and I've never seen VM give a warning.

The optical nodes may need more node devices fitted, more fibre pulled and tired lasers renewed. They deduce this from the SNR stats they collect.

The CMTSs at the VM end need the new higher capacity line cards and in some areas, new CMTSs have to be added to handle load.

Can 100 meg function without the cab upgrade? Badly, IMO, where a cab upgrade is needed. But prolly the optical node is more critical to 100 meg than the coax street cab.

Hope that explains more. Igni can amplify or correct anything I'bve not got right.

Every single cabinet is being done without any exceptions hence the timescale.

They are getting whatever work is required, be it a full replacement, tidy up or refurb, but each and everyone of the 11000+ cabinets is having some form of upgrade work done them, it is on our intranet and they proudly like to keep us updated as to the progress of the work with photographs showing before and after.

Some are even being moved if required.

sharing is caring... after all they're proud of their work.. please share

unless theres a security threat then don't bother... I'll get my shotgun

thanks for that Sephiroth

The same intranet that tells you to use Internet Explorer as a speed test then can't tell the difference between megabits and megabytes per second?

Yeah I'll take that with a pinch of salt, thanks. Especially since everything interesting or useful is never dissemminated, I'd rather take Seph's word over someone who's demonstrated complete incompetance at understanding technological concepts.

Martin_D · 12-01-2012, 20:19

i have called technical support but they say they don't give support for upload ???

I know more about the cabinet upgrades than you or him could ever know but then again you have a thing for me.[img]Download Failed (1)[/img][img]Download Failed (1)[/img][img]Download Failed (1)[/img]

Yes, you keep claiming that, and you also keep claiming you know more than everyone else despite being repeatedly proven otherwise. There's a word for that somewhere...

It's funny how you go from saying I'm wrong, and I should listen to the experts like Seph, then say Seph's wrong and I'm a stalker for agreeing. Bigot.
