Thanks, Brant, why don’t I take the first part of that and Joe will take the second. If I look at the foundation that we have now and this is very, very deliberate what we focused on when we began rebuilding the company if you will after the telco collapse in 2002. One of the things we wanted to do is to build a broader based company. Now, easily said, but challenging to do. It requires two basic things; one, a broader product offering and two, a broader customer base. And I think we have been working diligently at that over the last few years. Both of which are challenging, but I think we are in a position now where from a portfolio point of view around our specialty FlexSelect Architecture, I think we have made very good progress on that. On the customer base side, I would put it into two categories, Brant. I would say, if you look at our sort of Tier-1 major telco carriers, we have got a fair base of those now. So that if in any one quarter what we have been able to do in achieving 11 sequential quarters of growth when one is digesting, installation, etcetera, another one is ordering and trying to get a broad balance between that is clearly the endeavor. I mean if you look at our customer base now in North America, it's Sprint, Qwest, it's BellSouth, it's AT&T, it's Verizon, etcetera. We've got a strong customer base there. In the international with British Telecom, with TELMEX, with Korea Telecom, etcetera, we've got a broadening base now. And so that enables us I think to have more confidence around being able to deliver better than market performance. The other thing that I'd turn to is what I have talked about in some of my earlier comments, which is we see strong growth and there have been newer sectors, if you will, of government, research and education, some of the enterprise verticals, which are new to Ciena, and certainly some of the position in the cable space where we have seven of the top ten cable cos in North America. It gives us some diversity across all of that, but again makes us stronger as a business and allows us, I think, both more visibility and a more stable business model.
