Hi guys the street box on my road is wide open infact it's never been locked since the c&w days
Here's a pic can anyone explain what the difference is from the differnt colours where the cable goes in if it's the speeds what speeds?

Bolton is yellow. Middle is green and top is blue there's 2 lots of each

Sorry don't know how to add the pic. 24db, 28db mean anything?

it just means the attenuator needed so you get signal at property

AIUI, the higher taps have a higher signal level and generally would be used for properties further away from the cab.
