It's Fibre up to the Mux/DA where the telco is split off into the mux,thru the 30 channel line cards & then into the E sidesIt's then physically jumper wired up to the D sides which are the numbered Krone strips in the cabs,then onto the Drop cables to the house.(E & D sides are in the side hatch of the Mux & the cross connector lad runs a wire from his given E side to the given D side,from there go the distibution cables to the cabs)
The CATV runs from the DA (Distrubution Amp,next to the mux)where it is changed into copper.From there it goes into a DP cab.Amplified to the tap banks & sent off to the E cabs (smaller street cabs)
In each cab there are various ratings of tap banks.Each rating is the degree of atteniution of that port (ie,if you have a 12 & a 24 DBmv tap & the house is 120 meters away,you would connect the cable to the 15,not the 24 which has higher attenuation)
Each Mux/Dp is called a 'node' & there are up to 8 nodes in a ring.The 'power' runs in both directions so if there is a break,loss of service should be minimal.All the nodes run back to the 'headend' or 'hubsite'.
Forgive me if bits of this are'nt to accurate,the course was a long,long time ago.
