Will the name QSIG be the appropriate name in the future or will it be replaced by PSS1 (Private Signalling System no. 1)?
The formal name of the signalling system, as standardised at the Worldwide level by ISO / IEC is PSS1. The name QSIG was given to the signalling system when work on it first started in Europe in the late 1980s / early 1990s. It pre-dates the name given by ISO/IEC and is more widely known than that name. Both names will co-exist and QSIG will continue to be used as the marketing name.
