This the “home-grown” back office lab and is on development stage. The FRS is a 7200 Vxr NPE-G1. I only have a DCE v.35 cable so I’m instead using real NTU (Terra Uno). The FRS has controller E1 8 port PA, connected back to back, I call this “Telco Power”. For switching I setup 4 x 3550 switch.
My books have arrived but some them are out of stock from Cisco press.
