RCR STD-39, ARIB STD-T79 frame configuration
The uplink frame (TDMA) and downlink frame (TDM) both
generate data in frame cycles of 4-slot length (40 ms) defined
as a basic frame length. The PN9 pseudo random pattern of
the traffic channel (hereinafter called TCH) in a slot is
independent per slot and has continuity.

ARIB STD-T61 frame configuration
The uplink/downlink frames both generate data in cycles of 40
ms defined as a basic frame length. The PN9 pseudo random
pattern of TCH in a frame has continuity in each frame.
•
ARIB STD-T86 frame configuration
One frame consists of 6 slots and the data is generated in this
frame cycle. The PN9 pseudo random pattern of TCH in a slot
has continuity in all slots.
PN9 is continuous in each frame.
