Adjustment range: 0 to 15 slots
Default: 0 slots
Downlink Mode
Refer toFigure 3-1. In downlink mode, TFrame adjusts the number of timeslots that the
channel 1 radio frame is offset from both the Perch radio frame and the long code phase
zero. The total offset is equal to TFrame plus TSlot.
TFrame in Uplink Mode
Refer toFigure 3-2 on page3-10. In uplink mode, TFrame adjusts the number of timeslots
channels 1, 2, and 3 radio frames are offset from long code phase 1280. Total offset is equal
