Data Features
Advances in digital communications allows for new data features and services using the
radio link. This section describes the data features and services available for the Viking
mobile radio.
8.1 P25 Packet Data
P25 packet data transmission capability is available with Viking mobile radios. A Data
option switch can be programmed to toggle the data mode ON and OFF (or the menu
option can be used).
The P25 Packet Data mode allows a radio to act as a packet data modem for a remote
application connected to the radio through an RS-232 or Serial Line Internet Protocol
(SLIP) connection. The SLIP connection requires an Ethernet port.
Three P25-compliant conventional data operating modes are supported:
• Direct Radio to Radio mode - In this mode the radio will transmit data directly to
another radio without any involvement of fixed network equipment.
• Repeater mode - In this mode, the radio will transmit data on the inbound channel of a
repeater. The repeater will retransmit the data on the outbound to another radio listening
on the outbound channel.
• FNE data mode – In this mode, the mobile radio transmits data to a fixed network
computer connected to the FNE.
