DS3170_11 Datasheet, PDF (188/230 Pages) Maxim Integrated Products – DS3/E3 Single-Chip Transceiver Single-Chip Transceiver for DS3 and E3

DS3170 DS3/E3 Single-Chip Transceiver
Bit 1: Out Of Frame (OOF) – When 0, the receive frame processor is not in an out of frame (OOF) condition.
When 1, the receive frame processor is in an OOF condition.
Bit 0: Loss Of Signal (LOS) – When 0, the receive loss of signal (LOS) input (RLOS) is low. When 1, RLOS is
high.
