[j-nsp] My first juniper... kinda...

[Jason Lixfeld]

Looking at Juniper again after about 5 years, and I'd like some  
feedback.  I have a client who has a requirement to drive a 100MB link  
(so receive 100MB on one interface and transmit 100MB on another) on a  
1U device that is cheap.  I've heard great things about the J series.   
Based on the specs, a J2320 fits, however it doesn't support FE PIMs,  
FE EPIMs or GE EPIMS.  It does, however, appear to support a GE UPIM.   
What is the difference between a PIM/EPIM and a UPIM?  Throughput?  Is  
the latter a layer 2 module only, and you can't route over them?
