I've got a release this morning about Telecom's new Enhanced Unbndled Bitstream  Access:


Telecom launches first next generation mass-market wholesale broadband service
Telecom Wholesale today launched the first of a series of next generation broadband products to telecommunication service providers.

Enhanced Unbundled Bitstream Access has been successfully trialled with both CallPlus and South Island ISP Snap and is now available to other service providers.

“Enhanced UBA is the first of a new family of next generation network products allowing service providers to offer their customers real-time next generation services,” said Telecom Wholesale chief executive Matt Crockett.

“The launch marks the completion of a challenging project with invaluable input from our wholesale customers and a complex build to a tight timeframe.”

Enhanced UBA will be available nationally where Telecom has deployed next generation Ethernet broadband technology, also called ADSL2+.  Today, 56 per cent of fixed line broadband customers are served by ADSL2+ and this will increase to more than 80 per cent in the next three years.

“In an increasingly competitive wholesale market this is a critical first step to offering services to our customers that will bring the concept of IP services to life in New Zealand homes,” Mr Crockett said. 

“The new products will pave the way for service providers to offer their customers multiple digital voice connections, high-quality video conferencing, improved remote working and home security systems, all over a single access in the home.”
Enhanced UBA includes a channel dedicated to real-time IP traffic – such as voice or video – and a second channel specifically for Internet services.  Future variants of the product are expected to include additional dedicated channels built to cater for services, such IPTV or video-on-demand.

Enhanced UBA will initially be available in two variants with real-time channels of 40 Kbps and 90 Kbps.  Two more variants will be added to the Enhanced UBA family in early 2009.  All variants can be provided with or without an active analogue phone service.

Can anybody tell me how the CIR rate for VoIP is actually managed? Does Telecom traffic shape (ie shape all SIP traffic) to ensure VoI has guaranteed bandwidth or is this something handled by the ISP?

Not sure what 40Kbps would support. A high quality VoIP call needs 85Kbps; and then what if you want two calls?




Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?

40kbit will support one horrid compressed g729 call, possibly 2 if its trunked iax which 2talk now support, I have never bothered to measure it since it sounds so bad.

Yep, my point exactly - whats the point? Ya may as well just try you luck over regular DSL for that level of quality.

My understanding - having been involved in the discussions way back when - is that traffic is shaped at the PORT, rather than averaged across the dslam. It's a feature of the ISAM's, which have a fibre connection and features at PORT level. It's what allows me to user 180kbps symmetric guarenteed on Port 1 (Business), and No Shape on port 2. In practise it's all IP, not quite clear on what the upper rateshape limit is Wink

I get a MINIMUM speed of whatever I request - which is the fee I pay - with a specified latency and jitter factor. Rest assured the industry - the awake ones - defined something suitable for G.729 and G.711.

Of course it needs to be put into practise...

Regards
A

coffeebaron: Not sure what 40Kbps would support. A high quality VoIP call needs 85Kbps; and then what if you want two calls?

As per the original announcement:

Enhanced UBA will initially be available in two variants with real-time channels of 40 Kbps and 90 Kbps.

Pretty much tailor-made for G.729 and G.711 respectively don't you think?

If you want to cater for 2 G.711 calls simultaneously, that is going to cost big bucks and having said that, I don't imagine that the 90kbps EUBA plan is going to be cheap either Money mouth

richms: 40kbit will support one horrid compressed g729 call, possibly 2 if its trunked iax which 2talk now support, I have never bothered to measure it since it sounds so bad.

I know you guys look down your noses at G.729, but honestly, it's perfectly acceptable for everyday use, miles better than cellphone quality, which is still fine for most people.  If you want to have phone calls with 30Hz to 20kHz voice bandwidth, and 0.001% THD, then that's your prerogative, but for the rest of us, G.729 is perfectly adequate Tongue out
