ADDR=0x133: Receive J1 OOF

Bits 7-1: Reserved

Bit 0:

J1_OOF:

The J1 monitor framer searches for 15 consecutive J1 bytes that have a zero in their

MSB, followed by a J1 byte with a one in its MSB. When J1_OOF = 0, it indicates this pattern is
found, the framer goes into frame. When J1_OOF = 1, it indicates this pattern match is lost (three
consecutive J1 bytes with MSB errors).
