(3-4) Re-synchronization procedure / Startup procedure
A procedure required to switch control channel and main channel in the half-duplex procedure
A procedure which includes another modulation parameter exchanging is especially called the
startup procedure. (used for changing the communication speed)
Startup procedure
•
Control channel startup procedure: Refer to the 3-3 figure. (By exchanging MPh, the
communication speed is changed.)
•
"Control channel re-synchronization procedure" is not used.

Main channel re-synchronization procedure and Turn-off
The receiving modem re-synchronizes the main channel by using the PP signal. After B1,
starts receiving Primary Data.
The transmitting modem sends the scrambled 1’s for 35ms after Primary Data transmission
has been completed.
Both modems move to the control channel re-synchronization procedure or the control channel
startup procedure.
S
: Signal which sends alternately 0 point and a point which rotated 0 point
counterclockwise by 90 degrees
S
: Signal which sends alternately a point which rotated 0 point counterclockwise by
180 degrees and a point which rotated 0 point counterclockwise by 270 degrees
PP
: Special for adjusting an equalizer
B1
: High-speed signal of one frame length which is sent at the end of a series of startup
sequence in the selected modulation parameter.
