Excerpt from the Mission Critical April May Utilities article:
“Many electric utilities are integrating P25-compliant technology into their radio systems. P25, a mature digital radio standard in use for 25 years, has not remained static. As the session initiation protocol (SIP) and real-time transport protocol (RTP) world of IP signaling evolved, P25 followed suit with the introduction of the Inter RF Subsystem Interface (ISSI), a network-tonetwork interface, and the Console Subsystem Interface (CSSI), a standard interface for connecting thirdparty consoles to the radio network. These interfaces offer customer choice and competition among multiple P25 suppliers.
After 25 years of evolution, P25’s array of supplementary services and features is extensive. P25 is flexible and versatile, allowing manufacturers to add features such as man-down emergency call, transmit-and-receive cycling and request-to-talk (RTT) callback, a feature commonly used in the utility industry. While RTT is not defined within the P25 standard, both the CSSI and Common Air Interface (CAI) are flexible enough to introduce the signaling required to support it in both the consoles and radio terminals.”
David Deacon is founder and CEO of Etherstack. During the past 20 years, Etherstack has developed and licensed LMR technologies in Project 25 (P25), TETRA, Digital Mobile Radio (DMR) and NXDN to manufacturers around the world
