Capabilities-at-a-Glance

Refer to the Avtec Scout Consoles Capability Guide for capabilities common to the Scout system.

Capability Description
Interface Method (TIA-102.BACA) Scout supports a VoIP connection between the Scout IP console subsystem and the P25 radio subsystem infrastructure as defined in TIA-102.BACA, Project 25 (P25): Inter-RF Subsystem Interface Messages and Procedures for Voice Services.

Interface Method
P25 Phase 1 (Full-Rate 12.5 kHz)

Scout supports Phase 1 radio systems operating at 12.5 kHz using FDMA.
Interface Method
P25 Phase 2 (Half-Rate 6.25 kHz)
Scout supports Phase 2 radio systems operating at 6.25 kHz using two-slot TDMA or at 12.5 kHz using FDMA.
Unit Calls
(Private Calls)
(Individual Calls)

Allows a unit to send and receive a direct voice call to and from a single unit. Units can be either dispatchers or subscribers in the system.

Group Calls

Allows a dispatcher to establish voice communication with a group of subscriber radios or consoles. All members of the group hear the conversation.

Announcement Calls
(Broadcast Calls)
(Multi-Group Calls)

Allows a dispatcher to establish voice communication with multiple groups of subscriber radios.

System All Calls

Allows a dispatcher to establish voice communication with all subscriber units in a radio system.

Console-over-Console Transmit Interrupt

Allows a dispatcher with a higher priority level to take over a transmission from another console subsystem on the same talkgroup.

Console-over-Subscriber Transmit Interrupt

Allows a dispatcher to take over a transmission from a subscriber on the same talkgroup. The Scout System Administrator can select either Impolite or Dynamic Interrupt as the type of interruption the endpoint uses when a dispatcher interrupts a transmission.

Impolite Interrupt: The dispatcher takes over the transmission without notifying the subscriber who was transmitting.

Dynamic Interrupt: When the transmission is interruptible, the dispatcher takes over the transmission using Transmit Interrupt, which allows the dispatcher to politely interrupt an ongoing voice transmission on the same talkgroup. When the transmission is uninterruptible, the dispatcher takes over the transmission using Impolite Interrupt.

PTT-ID/ANI Alias

Gives a dispatcher a visual indication of the identity associated with the last voice transmission. An identity can represent the raw subscriber unit ID (PTT-ID) or an alphanumeric string representation of it (ANI Alias). The identity can display in the Activity History and on the associated endpoint pad using the ANI pad extender. For example, a PTT ID of 2527 can be aliased to “Fire 1.”

Over The Air Aliasing (OTAA) (per the P25 standard)

Gives the dispatcher a visual indication of the identity associated with the last voice transmission without requiring use of an ANI alias table.

Console-Controlled Encryption

Allows a dispatcher to enable encryption to prevent unauthorized listening to outbound voice communication.

The interface supports AES and DES encryption. ​Encryption key management is handled using the Avtec Encryption Key Manager. The dispatcher can dynamically change encryption methods and keys.

Encryption Key Manager

Allows a Scout System Administrator to load multiple encryption keysets for use by VPGate endpoints.

The Scout System Administrator can manually enter encryption keys for multiple encryption methods, and can also load encryption keys into the Avtec Encryption Key Manager using supported Key Fill Devices.

Short Data Message

Allows a third-party application to send and receive short data messages to and from subscribers via a CAD interface or data forwarding driver. Short Data Messages are typically used as a non-voice form of communication or for signaling. Short Data Messages could be used to generate an inbound call, to signal a subscriber to change frequencies for an upcoming announcement, or to send a pre-defined text message.

Status Message

Allows a third-party application to send and receive status messages to and from subscribers via a CAD interface or data forwarding driver. Status messages are typically used as a non-voice form of communication. Status messages could be used to signify personnel coming on or off shift, availability, or if they are experiencing an emergency.

Console Directed Call-Ins via Status Message

Allows a Scout System Administrator to configure console call-in codes that direct inbound calls to specific consoles.

Low Speed Data

Allows a third-party application to accept Low Speed Data from the radio infrastructure using the Data Forwarding Driver. For example, when a public safety official transmits, the subscriber could send low-speed data to relay its GPS location to a mapping system.

P25 Failsoft

In P25 trunking applications, P25 Failsoft allows a dispatcher to continue voice communication during degraded P25 system operation. When a site fails, designated repeaters enter the Failsoft state which allows the console and affected radios to continue communicating using Failsoft channels in conventional mode. Failsoft operation supports Conventional Group Calls, PTT ID/ANI Alias, Emergency Calls/State, Late Entry, Call Alert, and Console-Controlled Encryption. Endpoints can be configured to generate a call using a distinctive ringtone to announce Failsoft operation, and an ANI text string can also be configured to provide a customized visual notification. Endpoints can also be configured to generate an alarm to DMS when they enter the Failsoft state.

Unit Alert
(Call Alert)

Allows a unit to send or receive a request for another unit to call them back. Units can be either dispatchers or subscribers in the system.

Unit Check
(Radio Check)

Allows a dispatcher to verify operational status of a subscriber.

Unit Monitor
(Radio Monitor)

Allows a dispatcher to hear any audio picked up by a designated subscriber’s microphone. Depending on the system, there might be no indication to the subscriber that a Unit Monitor is in progress.

Stun/Revive
(Disable/Enable)

Allows a dispatcher to temporarily stun a radio so that it cannot transmit, receive, or power on and off. Reviving a stunned radio returns it to an operational state.

Emergency Calls/State Emergency Calls notify a dispatcher of an emergency situation in the field using a unique ring and visual indication. When a subscriber presses the emergency button or dials the emergency DTMF string, the endpoint generates an emergency call and activates the emergency state. Until the emergency state is cleared by the dispatcher, no further emergency calls from that subscriber can generate an Emergency Call.
Late Entry When an endpoint registers or changes a channel, allows a dispatcher to join an ongoing conversation without having to wait for the next transmission or call.
