4: Push-to-Talk Mode Operation

Introduction

Your Iridium Extreme® PTT device provides access to the world's largest
push-to-talk network, powered by Iridium. This section covers the setup
and use of push-to-talk service with your Iridium Extreme® PTT device.
While in Push-to-Talk mode, you will be able to access the push-to-talk
service. To access phone services such as phone calling, SOS, SMS,
voicemail and location-based services, you must switch to Phone Mode as
use of phone-based services is not supported in Push-to-Talk mode.
Iridium Push-to-Talk Service enables communities of users to connect
instantly, anywhere in the world. It is built on three key elements:
• Iridium Push-to-Talk Service enables communities of users to
communicate within defined geographic areas. Access requires monthly
device and talkgroup service subscriptions.
• Iridium Push-to-Talk Command Center provides a web-based
interface for managing subscriber access to available talkgroups and
definition of regional coverage for Iridium Push-to-Talk Service. This is
managed by a designated administrator(s) within your organization or
by your service provider.
• Iridium Push-to-Talk Devices provide talkgroup access and coverage
based on Iridium Push-to-Talk Service and enable individual users to
communicate with defined talkgroups based on Iridium
Push-to-Talk Command Center settings. These devices include the
Iridium Extreme® PTT device and other 3rd party devices that are
Iridium Push-to-Talk capable.
Once your Iridium Push-to-Talk Service is provisioned and Iridium
Push-to-Talk Command Center settings are properly configured, your
Iridium Extreme® PTT device can communicate with other devices.
