JPS, Cisco, and EADS showcased that with radio networks supporting  the  P25  ISSI,  JPS’  P25  Channel  Controller

(P25CC)  and  ACU-2000  IP  technologies,  customers  can achieve  a  cost-effective,  and  flexible  system  that  efficiently uses spectrum to improve public safety communications relia- bility and interoperability. The addition of an IP-based interop-erability  system  to  a  P25  system  and  its  ability  to  support inter-system  P25  communications  using  ISSI  allows  P25 users  to  communicate  securely  with  each  other  and  with authorized users on other voice devices such as cell phones, public  switched  telephone  network  (PSTN)  phone,  IP phones, PCs and laptops.

 “With the P25CC and the ACU-2000 IP, public safety agencies can achieve interoperable communications between disparate P25 and non-P25 radio networks by leveraging their existing radio and network investments.”

 “With the P25CC and the ACU-2000 IP, public safety agen- cies can achieve interoperable communications between dis- parate P25 and non-P25 radio networks by leveraging their existing   radio   and   network   investments,”   said   Keith McDonald, vice president of sales and marketing for   JPS.

“This  enables  our  customers  to  communicate  seamlessly with legacy radio systems that may operate on different fre- quencies or that may use other vendor technologies.”

During APCO, Raytheon and Cisco demonstrated open stan- dards P25 ISSI and IP Interoperability with:

- ISSI interoperability between P25 systems

- IP interoperability between P25 and legacy systems

- IP interoperability beyond radio
