The development of information and communications technologies (ICT) has facilitated the emergence of a complex global urban system in which many formerly lower-order cities have been carving out 'niche' specialist functions serving urban fields of transnational dimension. This is illustrated in the case of Dublin, which in recent years has been transcending its traditional role as Ireland's national metropolis through the development of a range of functions servicing mainly European markets. One such function comprises pan-European telephone call centre operations. The development and characteristics of this newly-emerging sector are described. It is argued that the growth of the sector confirms Dublin's - and Ireland's - dependent position in the international division of labour, and that its long-term sustainability is open to question.
