Telocator Alphanumeric input Protocol

Telocator Alphanumeric input Protocol was also known at PET and IXO protocol.[1]  This protocol was used for sending one way alphanumeric pages. Originally, devices like the IXO Device (right top) were used to send Alphanumeric Pages using TAP. Later, Motorola would create a similar device called the AlphaMate (right below). TAP Protocol is still used today in the still existing one way paging customer base and also to send one way messages to cellphones. In 1996, RAM Mobile Data introduced extensions to TAP for two way paging over the Mobitex network.
