[nsp] ONS15454 vs 12000 for the OC-3 demuxing

[Mike Lewinski]

So after having done a bunch of research and having learned quite a bit 
about Sonet vs. SDH, PoS, ATM etc. and realizing the constraints of the 
product we're buying, it seems like if we stay Cisco our two most 
logical choices are the ONS 15454 or a 12000 series.

Right now I'm leaning toward the 12000 mainly because it's a real router 
whereas the ONS 15454 seems like more of an ADM (albeit a fancy one 
that's not limited to a given transport) that's going to leave me still 
needing router interfaces to handle circuits I break down with it.

It certainly looks like this:

CISCO 12000 SERIES 2-PORT CHANNELIZED OC-3/STM-1 (DS1/E1) LINE CARD

...does exactly what I need. No PoS or ATM on this product, just allows 
me to peel of DS1s and supports "1310 nm single-mode (SM)". I can't tell 
if it's got SC or FC connectors, but I'm starting to suspect this is a 
non-issue (I've found at least two sources of convertors, Qwest says 
they are going to give me FC but most of the Cisco stuff I've seen has 
SC- since I have to have my demarc extended I'm assuming I can have my 
wiring contractors just terminate each end appropriately?)

Anyone using the 12000 channelized OC-3 line card who can verify my 
belief that this is going to do the trick for us? Or any arguments for 
the ONS 15454, given that at most we will have two OC-3s at this 
particular site and nothing else for the foreseeable future since we are 
pushing most of our expansion circuits into a different POP not yet fed 
by an ICDF colo?)

Thanks for all the responses! I received a couple privately that also 
indicated I was SOL for the 75xx/72xx channelized OC-3 options (we do 
have some PA-MC-T3s in service on 75xx and they work great btw :)
