Loop-Up Code Detected. Set when the loop-up code defined in registers
RUPCD1 and RUPCD2 is being received. See Section
Loop-Down Code Detected. Set when the loop-down code defined in
registers RDNCD1 and RDNCD2 is being received. See Section
details.
Loss of Transmit Clock. Set when the TCLK pin has not transitioned for
5µsec (±2µs). Will force the LOTC pin high.
Receive Unframed All Ones. Set when an unframed all ones code is
received at RRING and RTIP. See
Receive Carrier Loss. Set when a receive carrier loss condition exists at
RRING and RTIP. See
Transmit Current Limit Exceeded. Set when the 50mA (RMS) current
limiter is activated whether the current limiter is enabled or not.
Transmit Open Circuit Detect. Set when the device detects that the TTIP
and TRING outputs are open circuited.
PRBS Detect. Set when the receive-side detects a 2
(T1) Pseudo-Random Bit Sequence (PRBS).
