It is a confluence of a couple of different things. In no particular order, as I mentioned earlier, take Harmonic out of it, this industry is actually finally waking up to the fact like much of the rest of tech has, the combs that have a virtualization can be extremely powerful. The concept of Edge processing and the network can be extremely powerful. And by powerful I mean, something that can open up tremendous scalability, as well as cost efficiency. So that kind of a hard is hitting the industry, I mean we are certainly helping it, but it is not just coming from us. That's extrapolation in this industry of things that have happened elsewhere. So, we are confident that - we are increasingly confident that Cable is not going to be some kind of a isolated part of the broader tech landscape, but that is immune to the power of virtualization and the power edge processing. So, I think that is one reason and the Kagan data we cited earlier, I think speaks to that. Look, every day that goes forward and every day we move forward - we get more experienced with our own technology. We’ve become more excited about it, more convinced in inspiring capability. That comes out of four on lab, but I think just as importantly it comes out of our customer’s labs and their evaluations. And then third, by virtue of not just discussions, but the real substantive work that we are doing with early deployments and in the field, not our CMT solutions isolation, but fully integrated with the broader ecosystem. We are really seeing tremendous progress and the customers are working with that are actually seeing validation of some of the promise that it was alluded to earlier. The benefit of virtualization, the benefits of Edge processing in a distributed scenario. So, I characterize it is more than just discussion, customers are starting themselves to have a tangible aha moment saying wow, this stuff works. This stuff is real. Looks like my benefit, my business is going to benefit in this way that way and this way. So all of those things, I mean we have still got a long way to go and I don’t want to make it sound like it is done in by any means, but you look at all of those data points and yes we are feeling increasingly comfortable and confident. The risk I am gathering on, let me add one more thing, which is what I also alluded to which is discussions are expanding now to be more customers and particularly with the earlier customers they are becoming more about what volume deployment looks like. And what the forecast is going to look like. So that is kind of a tangible data point, a tangible discussion, it certainly also gives us confidence that what we're doing is real and it is something that we can, with increasing confidence bake into our plan.
