Callers' perceptions of post-dialling delays: the effects of a new signalling technology

Abstract

Abstract The present paper reports an investigation of the potential impact of introducing common-channel signalling (CCS) into the current telephone network. This technology would have the effect of greatly diminishing post-dialling delay (PDD). As such, its main benefits would be obtained by introducing it into the toll network, in which PDDs are much longer than in the local network. The issues examined concerned potential ‘contrast’ effects, in that reducing PDDs in the toll network may cause callers to be less patient with normal PDDs in the local network. Three laboratory studies were undertaken to evaluate caller impatience and abandonment under (1) the current system, (2) the current local system with a simulated new toll system and (3) the current toll system with a simulated new local system. Ratings of impatience and abandonment increased on local calls when the new technology was implemented on the toll network, but not vice versa. The explanation offered is based on a ‘cognitive’ contrast eff...
