Cabinets, Cross Connection No's 1, 2 and 3
|The Cabinet is the next cross connection point from the
exchange. In the 1950's they may have also fed Pillars which in turn
would have fed the distribution Points.
As telephone penetration rose, Pillars were not normally installed and the Cabinets feed the Distribution Points directly.
Pillars were painted dark green and made of cast iron.
Cables from the exchange are terminated on the 'E Side' of the terminating strip whilst the outgoing distribution cables were terminated on the 'D Side' of the strip.
The Cabinets and Pillars afforded flexibility in the network as any incoming wire could be connected to any outgoing wire. The connection made by a piece of two wire called a "jumper wire". Before the 1970's Cabinet terminations were actually screws which clamped the jumper wire or in the case of a through connection (i.e. wire 10 to wire 10) then two metal pins were used (See picture further down page).
Later on the screw style terminal blocks were replaced with plastic formers and the cable wires just pushed through numbered holes and left hanging. Connection was made with grease filled crimps (See picture below).
