Single Unit Building Physical Infrastructure Arrangement
Single unit buildings, whether dwellings or other buildings, should have a through-wall duct connecting an external access point to an internal network termination point, typically using 20mm electrical conduit for dwellings, with downward slope to prevent rainwater ingress and temporary seals for cable installation access.
A possible arrangement for the physical infrastructure for a single unit building is shown in Diagram 2.1 and is applicable both to dwellings and buildings other than dwellings. A simple through-wall duct is provided to connect an access point on an outside wall with a network termination point inside the building. Publicly Available Specification (PAS) 2016 indicates that a 20mm electrical conduit should be suitable in the case of a dwelling. The duct may be sloped downwards to prevent rainwater ingress and be fitted with suitable temporary seals at both ends to allow easy access for cable installation.
