Re: Small CMTS installsfor what its worth -- your c7609 chassis looks like a c6509 chassis in this drawing. more appropriate to use a 6509v-e chassis for accuracy's sake. q. |

Funny you mention that. IIRC we were using 6509s with the SUP720 (in effect making them 7609 routers). I cant remember if they were VE chassis or not though...I'll have to dig into my photo album and see if I can find some pics of it. That diagram is 7-10 years old. |

Cool can you go into the bonding on D3? is it still upconverted later or does D3 require the combo cards that can self upconvert? if its up/down converted later do the channels that will be bonded have to be programed in as to port 1, 3, ect or does it use them as a port group or something? |

I haven't done any D3 installs on the Cisco UBR7246 chassis, but from what I understand, the only card that supports D3 is the MC88V. It has built in upconversion, and outputs 4 QAMs per DS port. Any of D3 CMTSs that I've worked with (Cisco 10K, Arris C4, CASA) all had "Upconverted" RF outputs where you selected the Downstream frequencies and QAM(64/256) on the box (or on the EQAM in the case of the cisco 10K when using linecards like the 3g60 and manual depi sessions). |

And it has a mighty pretty price attached to it too, lol. Cheapest i have seen is 25k a card. At 100k for 4 cards, and then reserve cards to boot, that is what is keeping us from upgrading to d3. |

$25k/card is not a bad price -- all things considered. most of the d/c work that i do requires n7k-m132 cards -- list of about $45k/card. and you have to buy two chassis if you want all of the neat features.
i'm sure that if you get in touch with your friendly cisco se -- they can work something out with you.

q. As small of a system as we are, at 25k a card it would far surpass a return doing the retro... but i could always dream |

said by TomS_:Who pays list price though... Only fools. thats for sure. the enterprise customers i've worked with have received anywhere between 50 and 65% off -- with nearly 67% off smarnet in some cases. of course -- these customers are buying 15-20million at a time -- so cisco can bend over a little bit for them. q. |
