The Transmitted Packets section displays the QPSK reverse path data statistics for
the following transmission types that are included in the diagnostic screen:
Slotted Aloha—slotted-aloha style transmission values and are typically DAVIC
command and control messages or small reservations App messages
TDMA (Time Division Multiple Access)—TDMA values that are used by a
constant bandwidth connection
Reservation—reserved slot transmissions; most applications and some DAVIC
messages are sent this way
Ranging—number of calibration transmissions between the QPSK modem and
the DHCT performed during DAVIC sign-on that achieves the RDC power level
Errors—number of transmit packets for each of the three channel types that have
been aborted with a hardware error or time out error
The following table describes the field names and values within the Transmitted
Packets section.
