R/W
Description
R/W
The timing source used by the radio to precisely determine
current time and the start of each second. Valid values are Global
Positioning System (GPS), Precision Time Protocol (PTP), GPS with
PTP fallback, PTP with GPS fallback, and over-the-air (OTA). Base
radios are configured for GPS, PTP, GPS with PTP fallback, or PTP
with GPS fallback. Mobile radios are configured for OTA. An OTA
radio requires either a GPS or PTP radio within range in order to
synchronize timing.
R/W
Uniquely identifies the radio to the Communication Manager.
R/W
This IP Port is used to receive STFP messages from the
Communication Manager.
R/W
This is the IP Address of the Communication Manager.
R/W
This is the IP Port used by the Communication Manager to receive
STFP messages from the radio.
R/W
This is the number of seconds constituting an epoch. Valid values
are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30. The number of timeslots
equals 8 times the epoch size chosen. Note: This parameter must
match for all radios communicating.
R/W
This is the number of slots (125ms each) in advance that the radio
will request data from the Communication Manager. This delay
encompasses the time needed for timing markers to transit the
network, processing by the Communication Manager, and
resulting payload messages to transit the network.
R/W
This parameter requests the radio to transmit beacons in the first
time slot of each second when no message is received from the
Communication Manager for the time slot. Beacons are required
to maintain OTA timing of mobiles. Note: This parameter is
ignored and no beacons are sent when the timing source is set
to OTA.
R/W
If the selected timing input is missing for this duration, the radio
