In Saudi Arabia existed a few years back following number of switches
in the public telephone network:

   4      Ericsson     ARE 13     transit switches
around 60 Ericsson     AXE 10     as both local and transit switches.
                                  Some of the transit switches are used
                                  to switch cellular mobile traffic
                                  according to the NMT-450 system.
around 10 Ericsson     ARE 11     local switches.
          Philips      PRX        local switches, mostly rural.
          Philips/AT&T PRX-D/ESS5 Local switches
  10      Hitachi                 local containerized switches.
                                  (Old crossbar switches)
   2      AT&T         ESS1A      Used at the international airports in
