Advanced Caller ID Option: TRsSim / AI-7280 or AI-80
The Advanced Caller ID functions is an optional component to the TRsSim software. It expands the basic Caller ID capabilities to provide a wider range of physical and data layer programmability useful for compliance testing to TIA, Telecordia, or ETSI standards.

The following table lists the features supported by this option along with restrictions that are specific to the hardware product (AI-7280 or AI-80) the TRsSim software is connected to.
