Did they specifically mention DOCSIS? No idea why you were told that.

BT's Ebbsfleet trial is not DOCSIS 3, its using GPON. Gigabit Passive Optical Network, which carries a variation of SDH/PoS. STM-16 downstream, STM-4 upstream to each PON splitter. Tad pointless throwing DOCSIS down there.

DOCSIS is an access network technology, not a core network technology and is used exclusively for delivery of bandwidth down HFC networks as they are uniquely constrained by having to deliver their bandwidth in 6/8MHz slices. It's completely pointless using it for FTTK/P networks, why cripple an unchannelised network with GHz of bandwidth by forcing it to use bonded 6/8MHz channels? You can send 2.4Gbit/s down GPON to a single customer, rather pointless sharing 200Mbit between them using DOCSIS.

The tech that VM will use will be EuroDOCSIS 3 Silver certified. The original trials in Ashford along with the equipment until certification was Pre-DOCSIS 3, which btw means that it hadn't passed the certification testing. I believe that the modems will be firmware upgradeable to EuroDOCSIS 3 Gold, as would the CMTS.

Just going by what ask4 supervisor told me

Learn something new everyday, rep given.

Yep, got told docsis3 gold, did question it at the time but i got put through to a manager (?) who was adament the network was docsis3!

Apologies for the confusion but I'm not sure who you spoke to or why they told you that. If you'd been put through to the manager that would have been myself. Strange

thats all im sure others have seen their area has "completed" status!

so true...so true...

"In terms of ‘uploading’ speeds and details of our traffic management policy, these are still being worked on."

Does this mean they might actually be considering an upload speed that handles the overhead of 50Mbps downloads?

1.5Mbit upload...

traffic management policy and upload speeds thats what im very interesting it..

any news on this yet?

Upload speed is 1.5Mbit (business package has been confirmed as 2Mbit upload and they always get more so...)

50Mbit has STM/Traffic management applied at the end of the trial.

The limits for this are low...20mins usage max as with other stm tiers.

What does it reduce to?

Currently 10Mbit (512K upload).

Though i feel this will go upto 20Mbit at launch due to their HD service requiring 20Mbit minimum.
