| Nothing to do with MPLS
Would you kids go back to playing Xbox, this has nothing to do with MPLS and had everything to do with carrier level speeds. Most carriers run OC-192's (10gig)interfaces, this allows AT&T carry more customers on a single fiber than before. Sure you can combine multiple OC-192's to achieve 40g speeds but over 4 different fibers.
Some of you need to read alittle more before running off at the mouth.

I know you think you are better than everyone because you have those letters and numbers after your name.. but last I checked CCIE does not certify you to be a HUGE DICK. |

Is your fiber grounded?

Last time I checked the Cisco 454 ROADM platform can multiplex 32 10Gig wavelengths over a single fiber pair.
Infinera can handle as many 80 10Gig wavelengths across a single fiber pair.

The Cisco 15454 ROADM platform can also handle 80 10Gig wavelengths over a single pair of fibers. |

Ok I knew this was coming. You have to de-mux at some point when you use DWDM. So if you would like a 40 gig link you need to have 4 fiber xenpack (go ahead google it) 10g interfaces at each end. With the new OC-768 you only need one physical interface.
I doubt you've even come close to touching an ONS from Cisco. |

Too bad the 15454 still is still limited by 4 high speed slots per chassis, which makes it all but worthless for 10GigE aggregation. |

15454 ROADM does not use the XC or XC10G cards, the backplane is only used for power and configuring the cards in a ROADM shelf. There is no high speed card limit for a ROADM config.
It can take 12 10Gig wavelength cards per chassis, or 6 40Gig wavelength cards. |

Of course the waves have to be muxed and demuxed somewhere...I'm not arguing that point.
However, you original post makes it sound as if AT&T only ran a single 10Gbps wavelength across a pair of fiber through the network's core. (The core is what the article is talking about.)
Certainly a carrier as large as AT&T has been leveraging DWDM technologies throughout the core of its network for years.

Newark, DE | We could go down the this road of features and commands from the ONS line-up, but Im sure you'd just google the answers.
As I said before where is your number? |

Is that your stock answer any time someone dares to challenge you? Besides, what does a CCIE number have to do with installing a 454 chassis?
Congratulations on obtaining your CCIE. Now that you have your "number" you sir are clearly a superior human specimen. We should all bow before your super inflated ego.
I have read and heard stories about guys like you. You know the story I'm talking about...A hardworking network engineer passes the IE lab, and ten seconds later he become a total jerk. (It's really sad, you probably used to be a nice guy.)
I've met a number of CCIEs over the past few years and you are the first CCIE I've come across that was a total ass. On the bright side, you did manage to confirm the story. |

| Dude..give me something to work with here. Any kid off the street can screw in a chassis. What nodes/rings have you built? what type? etc.. "installing" a chassis just doesn't cut it. I'm not a jerk, just sick of the wannabes throwing out lies about AT&T, Cisco and any other stuff they want to make up. |

Mike, we do plenty of sonet and ROADM in Charter, as charter_hsd is telling you. Give it a rest. He's no wannabe. |
