PABX No. 3 Racks | |||||||
The GPO were not allowed to install any large PABX installation, so this was
left to approved PABX suppliers. The GPO/BT however, had to maintain the
equipment once installed and connected to the Network.
PABX 3 systems were installed by Ericsson/Plessey, GEC, TMC & STC. Click here for Plessey PABX No. 3 The pictures below are of typical racks and there are subtle differences
between manufacturers. |
