Airline's GDS (Global Distribution Systems) use a vast range of Pseudo City codes which identify placement of POA (point of access) CRS (computer reservation systems). For example, if a location, such as a travel agent, a corporate location, hotel, etc., required access to an airline reservation system, a Pseudo City address would be assigned to that location.
Additionally, there are locations which have nothing more than a printer. These exist when, for example, a hotel, a hire car company, etc., have a printer designed to print out incoming hotel or car reservations. There are no computers attached, no access to the reservation system, etc. Those also require a ;Pseudo City address and identifier.
Finally, printers, inbound only data monitors, etc., positioned in baggage areas, ramp activities, flight ops, catering, etc., all require a Pseudo City address, which does nothing more than identify the device and allow for AIRIMP data flow.
One more example; virtually every boarding pass printer at an airline gate has its' own pseudo city address, as do kiosk check-in machines.
As the pseudo city address above is not an IATA or ICAO location, the pseudo city address shown is strictly an internal 'telcom' address which could be used by Sabre, Galileo, Amadeus, Pars/Shares, or Abacus systems. Without the carrier code proceeding the pseudo city, or the QXX ID, it's impossible to determine to which airline this specific address belongs. It could even, conceivably be an SNCF (French Rail), Deutsche Bahn (German Rail), or ATOC (Association of Train Operating Companies, including Eurostar), address.
