The Office Hotel/Hospitality Link Interface is a proprietary, IP-based protocol used for building a hospitality Property Management System (PMS).
Built on the same protocol element as the well-known AHL for OmniPCX Enterprise, this interface enables Hospitality and Healthcare applications to benefit from all features of the OmniPCX Office.
In version R.50 and above, the new driver (called OLD, for Office Link Driver) adds call accounting functionality, which generates XML tickets.
