A meet-me room (MMR) is a place within a colocation center (or carrier hotel) where telecommunications companies can physically connect to one another and exchange data without incurring local loop fees.
An MMR provides a safe production environment where the carrier handover point equipment can be expected to run on a 24/7 basis with minimal risk of interruption.
To interconnect, each company orders a patch from their cage or suite to the MMR and then arrange for the organization running the facility to connect them together.
Typically, a meet-me room will discourage or disallow customers from installing large amounts of equipment.
An Internet exchange point can also be present in a meet-me room to allow many organizations in the meet-me room to interchange traffic without having to make physical interconnections between every possible pair of organizations.
