P25 E-Book Forward: Strides in Interoperability

By Sandra Wendelken

Following Project 25 (P25)’s 25-year anniversary in 2014,

the standard has continued on its journey to enhance

interoperability.

Progress continues with the wireline interfaces, including

the Console Subsystem Interface (CSSI) and the Inter Subsystem

Interface (ISSI). These standards are important to the technology’s

continued evolution. Several push-to-talk (PTT) vendors are using the CSSI

to connect P25 networks with commercial Long Term Evolution (LTE)

technology and extend PTT services to users with smartphones on

commercial networks. This development will be one to watch as the First

Responder Network Authority (FirstNet) gets rolling.

In addition, a study item on a standard for LMR, including P25, and LTE

interworking was submitted to the Third Generation Partnership Project

(3GPP) for consideration in an upcoming release of LTE. The federal Public

Safety Communications Research (PSCR) program is also working to

integrate P25 and LTE in the future.

A new advisory panel (AP) was established in late 2015 to help get the

P25 Compliance Assessment Program (CAP) moving forward again.

Funding from the Department of Homeland Security (DHS) will help ensure

the program continues down the right path. The AP is comprised of P25

users who have a strong desire to maintain the program and the benefits it

has for users.

P25 users must do their part to remain educated about the

latest developments in the technology and to ensure the equipment they buy

adheres to all the standards. Ignorance means a compromised system. If

you don’t have time to do the proper research it’s advised to hire a credible

consultant. Users have made a good first step by downloading this e-book,

which provides all the latest information on the standard, interoperability,

integration with FirstNet and helpful user deployment details. The e-book

offers a wealth of information to ensure P25 procurements run smoothly and

cost effectively.
