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.

Tagging

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.

Key Value Description Use
telecom exchange The exchange building should be mapped as area for those which are located in a dedicated building. For the others (recent ones in street cabinets, part of building,...), a node may be used. mandatory
building service When located in a dedicated building. optional
building:prefabricated yes When the telecom exchange is located inside a prefabricated building optional
man_made street_cabinet When the telephone exchange is in a street cabinet. optional
street_cabinet telecom required with man_made=street_cabinet
telecom:medium <medium type> The type of local loop it is used to. See below for possible values. recommended
operator <operator> The name of the company that operates the central. recommended
owner <owner> The name of the organization which has the ownership of the central (State or local administritive organisation for example) optional
ref <reference> Telephone exchange reference if applicable. See ref:FR:PTT=* or ref:FR:Orange=* for French example recommended

More than one exchange in the same building

Due to fibre optic modern networks rollout, situations can occur with multiple different nodes in the same building. We should not tag the building itself but create as many nodes as exchanges exist in the building.
In case of copper and fibre exchanges are located in the same place two nodes should be created and get respectively telecom:medium=copper and telecom:medium=fibre.

See way 35739901 with no telecom tag.
Two exchanges are on node 6275178274 and node 6275178273 inside the building polygon.
Once the copper network decomissioned we'll delete the copper node and the fibre one will remain untouched.
