Data can be downloaded to an ADSI telephone in one of two modes:
- Server display control (SDC)
- Server display control mode is used when an IVR voice application uses
a continuing connection between the generating device (such as Blueworx Voice Response) and
the ADSI telephone. Use this mode for downloading data that is specific to
the user; for example, information about the user's bank account.
- Feature download management (FDM)
- Feature download management mode allows a number of alternative display
and key setups (known as overlays) to be downloaded and stored in the ADSI
telephone. These overlays can be selected by various signals (or events) that
occur at the telephone. The overlays remain active on the telephone after
the telephone call that downloads them has been completed.
