Base Unit TR-DATA Signal (Normal mode)
Base Unit TR-DATA Signal (Normal mode)
Base unit sends a dummy slot and receves all 6 slots every frame in normal mode.

RX-DATA included in TR-DATA
RX-DATA of BU is for checking for TX of HS or RX of BU.
When "TX-CW" mode in Handset, RX-DATA of base unit is LOW. (*1)
In the other case, RX-DATA of base unit is random. (*2)
Handset TR-DATA Signal (RX data in RX CW mode)
Handset TR-DATA Signal (RX data in RX CW mode)
Base unit bursts a dummy slot in normal mode in any channel.
Handset should be worked in test mode in same channel as base unit.

RX-DATA of handset is LOW after receiving dummy from base unit.
RX-DATA just before that is same as dummy slot data of base unit.
