Hi there,

Just phoned up Vodafone and asked if what they use technically is any different to Telecom's.
They told me that Vodafone broadband is more reliable because they use 2 ports comapred to Teleocm only using 1 port. Does anyone know what they are talking about?
Vodafone also told me that they have their own equipment installed at the exchange that they shares with Telecom. Is this true?

Are they saying they are using bonded DSL, first I have heard, and unless they/you pay for two pairs from Chorus, which is unlikely as the cost would make it a deal breaker, otherwise no real difference.

Any real difference's are, possibly slightly higher sync speeds due to lower noise margin target, but often the reality is not all that much, maybe 10% at most, and probably better aggregation backhaul capacity, how much of an advantage this is is debatable, if you are on a Telecom wholesale connection on ADSL2+ then typically the local aggregation capacity is probably not issue, but depending on where you are ymmv.

Its not 2 DSL ports the card on the Dslam have 1dsl and 1voice port only

Its no different to how TCNZ set them up really,

The advantages Vodafone have on the red network the Dslams are made by the same company as the modem / routers

Thanks John

Red Network... 


- Red network has a more aggressive noise margin of 6dB which means you'll get higher sync rates for the same distance compared to a connection to Telecom wholesale gear in the exchange.

- Vodafone claim better/lower contention ratio's on their backhaul, at least they did when the network came out.

Not so good: 

- No Vodafone gear in cabinets yet (sub loop unbundling), if you're in a cabinet zone or will be you will be better off on plan provided over Telecom wholesale gear.

- Lower Noise Margin may result in more stability problems if you have bad wiring / dodgy lines in your house / area

Keeping on topic - the Vodafone sales person told you incorrect information to get the sale. Consider what you want with Broadband, data useage, and telephone services.
