The iDEN (integrated Digital Enhanced Network) interface supplies T1 and GPS
antenna connections, via the iSC-3, for the RadioFrame System. The iDEN
interface also provides an Environmental Alarm System (EAS) and a Channel
Service Unit (CSU) for the T1 input to the iSC-3.
2.1.1.1 integrated Site Controller (iSC-3)
The integrated Site Controller, or iSC-3, consists of a site controller and an
Environmental Alarm System (EAS). Most systems are configured with two
iSC-3s (an active and a standby) and one EAS. For more information about the
iSC-3, refer to the Motorola document Gen 3 Site Controller System Manual,
