Supervisory GPRS JACE to subordinate GPRS JACE

In this “mobile-to-mobile” use case, a permanent connection between a GPRS-equipped supervisory JACE is maintained to a subordinate GPRS-equipped JACE.

As shown in Figure 5, the addition of the hub connecting the remote subordinate JACEs also allows for alarm “hopping” to the supervisory JACE.
