Pattern Sync Criteria: To acquire pattern synchronization:
- For MARK, SPACE, ALT, FOX, T1SET, T1RESET: = 24 + 32 = 56 bits, SYS511, X25 511 =
entire pattern = 4088 bits
- Pseudorandom = 24 + 32 = 56 bits
- Loss of pattern synchronization: Adjustable - user may set from 1 bit error to
20000 bit errors in a 100000 bit test block
