When Linking from the Handset (when becoming STBY to TALK), DATA is transmitted in above format. The combined
portion of DATA 0 and DATA 1 is transmitted in LINK requesting DATA (40bit) format first. Then, when LINK OK (ACK-OK)
DATA
(46bit) is returned from the Base Unit, it is sent as LINK from DATA after changing the combination of DATA 0 and DATA 1. And
the DATA Delimit is between each Frame as a stop.
The contents of LINK requesting DATA and LINK form DATA are different depending on each operation.
