It was intended, in an earlier plan, that conversion of Edgeworthstown manual exchange to automatic working would be by means of a cross-bar type exchange parented on Granard switching centre. The necessary equipment was ordered on that basis. However, arising from the proposed early use of digital exchange equipment at Longford and Mullingar, it was decided that the most advantageous course would be to convert Edgeworthstown by means of digital equipment, thus avoiding the necessity for a new underground cabling scheme from Edgeworthstown to Granard. A cable suitable for digital transmission systems has been provided between Edgeworthstown and Longford and will also cater for conversion of Ardagh and Rathowen exchanges.
It is expected that the conversion work will be completed in the second half of next year.
The cross-bar equipment originally ordered for Edgeworthstown has been deployed to an area where development by this technology is continuing.
