ISSI.1 Network Gateway Subsystem

Enabling Project 25 ISSI wireline interoperability

When a disaster strikes or large events require complex coordination and

interoperability among first responders, network operators require versatile

and immediate interoperability solutions to enable them to respond to the

sometimes highly unpredictable nature of emergency situations. This has

created an immense and well-understood need for network interoperability

and the creation of System of Systems interoperable networks.

Today’s ASTRO

25 trunked networks use IP-

based call processing and the Project 25 (P25)

Common Air Interface. This means Project 25

(P25) trunked networks can now be connected

using IP-based gateway technologies. The Project

25 Inter-RF Subsystem Interface (P25 ISSI) is one

of the ﬁrst end-to-end digital IP network interface

standardized by TIA. Motorola has implemented

this interface in a software application called

the ISSI.1 Network Gateway (ISSI.1 NGW)

Subsystem, which will enable P25 ISSI equipped

trunked networks to implement end-to-end digital

interconnectivity to meet the needs of Project

25 system users who need to interoperate.

The ISSI.1 NGW supports basic call services

including ISSI Group Call, ISSI Emergency Call

and end-to-end P25 encryption. It is simply

added to an ASTRO 25 trunked core, and does

not require any software upgrades to the

core, site equipment, consoles or radios.

ISSI.1 Network Gateway Advantages

The ISSI.1 Network Gateway is an easy and cost

effective way to connecting Project 25 systems

together for interoperability. The ISSI.1 NGW can:

• Connects disparate systems – enabling

talkgroups from differing System IDs, WACN

IDs, different P25 system vintages, RF bands,

manufacturers and coverage areas to be connected.

• Enable task force interoperability – First

and second level responders can be securely

and digitally connected together across

multiple systems and vast coverage areas. This

versatility will undoubtedly become a vital tool

in responding most effectively to unpredictable

or unusual projects, events and disasters.

• Permit multiple P25 ISSI enabled networks to

interconnect – networks from other Project 25

trunked manufacturers can be connected together

in a regional network interoperability solution.

• Provide connected roaming without modifying

subscribers – enabling wireline connectivity

without requiring software upgrade to the

subscriber devices to enable roaming.

• Reduce funding and upgrade dependences –

enabling different ASTRO 25 vintage systems to

be connected, lessening inter-agency funding

cycle dependences.

• Retain individual system and ﬂeetmap

autonomy – preserves the User Conﬁguration

Server databases on each system enabling

operational autonomy among the connected

systems and ﬂeetmaps.

• ‘Bolt-On’ to existing ASTRO 25 networks –

quickly and cost effectively add ISSI.1 NGWs

to an existing and deployed ASTRO 25 network

without requiring the network to be upgraded

to a new version and without upgrading

subscriber or Control Channel (CCH) software.

• Enable end-to-end encryption without

transcoding – using network connectivity delivers

performance with lower delays, better audio

quality and more robust call services than can

be accomplished when analog or transcoding

methods are used.
