[c-nsp] High Density T1 Question

[Richard J. Sears]

We currently utilize Cisco 7513s with VIP2-50 and PA-MC-2T3 PAs to
terminate almost 500 T1s

We continue to grow and now I am getting ready to accept an OC48 from
one of my carriers as opposed to accepting DS3s from them. 

We operate ONS 15454 boxes to manage out OC48 backbones and was going to
bring the OC48 into the ONS box, and bring it out DS3 back into my 7513s.

My question is that I would like to come out of the ONS box with say an
OC3 or OC12 interface and plug that into a PA or whatever would handle
T1s at that level.

I have a combination of GSR12Ks, 6509's, 7513s, and 7206VXRs I am using
to terminate GIG, OC3, DS3 and T1 customers. T1s are by far my greatest
growth problem and 7513s take a lot of space :-)

I am looking for advice on how to pull an optical circuit from the ONS
box and terminate it optically into a card (or cards) to do my T1s.

Thanks !!
