V.35 data connector				34-pin female MRAC connector

LOS light (red)				Loss of signal at the local end

Bad CLK light (red)				Loss of clock or clock out of range

Yellow alarm light (yellow)				Loss of packet alignment (NTM) or frame alignment at remote end

DSR light (green)				The DSR lead is high (ON)

DTR light (green)				The DTR lead is high (ON)

RXD light (green)				The receive data line shows activity

TXD light (green)				The transmit data line shows activity

Fail light (red)				An error occurred. First, reset the card with resetcd f. If the LED comes on
