[nsp] Suggestions on terminating a bunch of T1's

[Richard J. Sears]

We currently terminate between 400 and 500 T1s utilizing two 7513s with
Dual RSP4s, Vip2-50s with PA-MC-2T3s and it works great. 

Is there any way to bring them native in on CT3s as opposed to copper
and having to run them through an M13...?
