Re: Gateway replacement, new speed upgrades? fastpath?

Looking at the profiles, it makes sense that one would need pair bonding for the new speed tiers, regardless of what your sync rate is. The 8d profile is only capable of a 50 Mbit/sec transmission at the most, which would not be nearly enough for a 45 Mbit/sec service on say a 50 Mbit/sec profile, which would leave absolutely no overhead above the profile. That just isn't workable. Until they change to a profile with a wider frequency range, it won't be possible to do 45 Mbit/sec on a single line, regardless of the max sync rate.

Very good point, overlooked on my part...

Your assumption is that the profile will stay on 8d. I don't think that is the case. I think if a loop qualifies it will get a profile of at least 12a here in the near term to support a 45Meg synch rate on a single pair. Pair bonding may be required on the 12a profile to support the 45Meg Power tier with Uverse TV, depending on how they budget the bandwidth. Otherwise, pair bonding should generally not be required for a 45Meg Internet only Uverse connection with a line that currently supports the 32Meg profile.

It sounds like they will eventually go to the 17a profile maybe within the next year to support 100Meg and potentially up to 200Meg with pair bonding.

The question is if the existing hardware can support these new profiles with simple firmware upgrades. If so, depending on the average copper quality in the ground, they could keep iterating on this model for some time to come. Then it is just a matter of where the limits of physics start to go well beyond the average quality of existing copper in the ground.

hahaha...can u just imagine, in 100 years the advancement, ATT could literally roll out a massive "rope" of bonded copper from the VRAD and just light up the dark fiber they have hidden everywhere...
