An Exchange (722-06-05) is a place (i.e physically a building or a cabinet) containing several services equipments including telecom switches, transmission and amplification equipment, main and/or secondary distribution frames. It connects local loops (subscribers side) to backbone and long distance networks.
A telephone exchange is a building, a part of a building or in some countries a street cabinet which connects a subscriber's home with the service provider devices. A lot of switching equipments are located in exchanges, including the Main Distribution Frame which is actually inside the building (and shouldn't be confused with the real building). This document means that exchanges can be hosted in street cabinets for sake of space savings, which doesn't imply that all telecom street cabinets are actual exchanges. Especially connection points shouldn't be confused with real telecom exchanges.
