The answer is the MBSII range of Centrex telephones. These included the M522, M5008, M5208, M5216 and M5316 models.
Thursday, 14th September 2017 was a memorable day when this milestone was achieved at GPC Electronics’ Australian facility in Penrith (Sydney). Production commenced in September 1996 at a specially fitted out new GPC building in Lemko Place in Penrith. All GPC production, including these telephones, was brought under the one roof when we moved to our current factory at 138 Blaikie Road Penrith in 1997.
Principally exported to Canada and the USA, with some sales in Australia, GPC is proud of our association with these notable Canadian companies and the opportunity to supply these telephones over such a long period of time.
