made up of 6 SFs, but some F-bit are used as Concentrator Bits, Spoiler
Bits, Maintenance Bits, Alarm Bits and Switch Bits. Each frame consists
of one overhead bit (F-bit) and 24 8-bit channels. Its Frame Alignment
Pattern is ‘001000110111001000110111’ in 24 consecutive F-bit posi-
tions. If the Frame Alignment Pattern is found in 24 consecutive F-bit
