Data outlet plan symbol
Plan symbol for a structured-cabling data outlet, usually tagged with the number of ports and outlet ID.
In plain English
What does Data outlet plan mean?
Data outlets are drawn as a triangle or a small box tagged D or TO at the wall or floor box position, with the port count as a numeral. Each port is labelled with an ID that matches the patch panel in the communications room.
A simple example
The plan symbol tells the cabling installer how many cables to pull to each position and supports the cable schedule. It also helps coordinate with power outlets, since desks normally need both.
What the drawings help you do
The symbol does not state cabling category, shielding or connector type. The structured cabling specification covers this.
