Exchange-to-premises-wiring

It is often useful to know the terminology that Openreach use to describe the parts of the wiring between the exchange and the premises.

This diagram shows some of this, including:

• E-Side (Cable from Exchange to the Cabinet)
• D-Dide (Cable from the Cabinet to the Distribution point, which may be in the building or on a pole in some cases)

• DP = Distribution Point
• PCP = Primary Cross-Connection Point
• SCP = Secondary Cross-Connection Point
