3.8.3
Synchronization Bit.
synchronization
shall alternate between binary
O and from frame to frame. It should be coded as binary-O for the first frame transmitted.
3.8.4 Expansion Bit. When following this standard, the expansion bit shall be set to binary O in each
frame. The purpose of this bit is to allow for future transition to as yet undefined coding techniques.
