820s & a Crane! Installation to improve bandwidth to core of network branch

We recently installed a new 820s to feed a branch of our network with more bandwidth that is in high demand.  This is opening up major capacity for a PTP800 that was starting to hit limits.  Sometimes a crane can be a good friend of the rope and climbing crew!


Nice shots. Congrats. What would be, according your experience and knowledge, main differences/advantages with 820 vs former 800 series?
