DAC RA711 GSM integration into Global Instech manufactured housing

Global Instech, DAC’s Thailand based distributor requested DAC’s assistance with a bid for the replacement of emergency telephones on the 30 km stretch of Bangkok Suvarnabhumi Airport Toll Road. The existing analogue telephones had been in service for twenty years and where now experiencing a variety of problems including intermittent connectivity requiring frequent hands on and costly maintenance.

The Expressway Authority of Thailand was also considering another manufacturer from China and requested a trial of both sets of telephones. The trial was conducted over a two month period exposing a number of issues with the Chinese telephone becoming non-functional due to the extreme heat and rain. DAC telephones functioned well during the trial without issue and were chosen for the project assisting Global Instech.
