Service devices are active equipment which deliver service to connected customers. It can be for instance a DSLAM, a telephone switch, or more recently an OLT for optical networks. It excludes amplifiers or repeaters installed along local loops or long distance lines.
This proposal isn't intended to fully define how service devices work, since it's a complex topic and not so relevant for OSM.
Such service devices are usually installed in telecom exchange buildings, but they can also sometimes be installed outdoor, in standalone street cabinets. This may be because of a lack of physical space in exchange buildings, or to increase data rates in suburbs areas by shortening the length of the copper local loop.
Those cabinets must only contain service devices without a distribution frame, otherwise they turn into an actual telecom=exchange in a cabinet. Furthermore, a service device cabinet does not create a new local loop: it simply serves a subset of customers on an existing local loop, and connects back to an upstream telecom exchange building.
