Purpose

JREAP was developed due to the need to communicate

data In the pursuit of knowledge, data (; ) is a collection of discrete Value_(semiotics), values that convey information, describing quantity, qualitative property, quality, fact, statistics, other basic units of meaning, or simply sequences of sy ...

to the message format or content. JREAP takes the message from the format it was originally formatted in and changes the protocol so that the message can be transmitted over Beyond Line-of Sight media. JREAP is the protocol and message structure for the transmission and reception of pre-formatted messages over communications media other than those for which these messages were designed. JREAP provides a foundation for Joint Range Extension (JRE) of

;JREAP A :JREAP A uses an Announced Token Passing protocol for half-duplex communications. This protocol may be used when several terminals share the same JRE media and take turns transmitting or in a broadcast situation when one transmits and the rest receive. It is targeted to data rates down to 2400 bits per second (bps) on a serial data interface with a TSEC/KG-84A/KIV-7 or a compatible encryption device used for data security. It is designed for use with media such as: 25-kHz UHF TDMA/DAMA SATCOM, EHF Low Data Rate (LDR) Forced Mode Network Operations and 5 and 25 kHz UHF non-DAMA SATCOM. ;JREAP B :JREAP B is a synchronous or asynchronous point-to-point mode of the JREAP. This mode is similar in design to the Half-Duplex Announced Token Passing protocol used by JREAP A. This mode can be used with SHF and EHF LDR point-to-point mode synchronous connections, STU-III operations via phone lines and other point-to-point media connections. This JREAP application presumes full-duplex data-transparent communication media. ;JREAP C :JREAP C makes use of the
