FTAP Configuration
Sets parameters for the FTAP application. The FTAP protocol specifies the procedures
and messages to control the Forward Traffic Channel for subtype 0/1 signals.
DRC ← FTAP Configuration
The forward data rate is defined in terms of the "DRC" (Data Rate Control) "Index",
which is signaled on the control channel sync. message.
The DRC section shows the data rate and slot count ("# Slots") for each selected DRC
Index. A DRC Index "0" stops the flow of FTAP packets to the AT.

Loopback Enable ← FTAP Configuration
Indicates whether the AT under test shall transmit FTAP loopback packets in order to
provide Packet Error Rate (PER) information. Loopback mode is a prerequisite for FL
"PER" tests. It is always on while a "Forward" test application is active; it is off while a
"Reverse" or a "Forward and Reverse" test application is active. See
