QRSS
SR.3
Set when the QRSS pattern is present at the receiver.
AIS
SR.2
Set when the AIS pattern is present at the receiver.
NLOOP
SR.1
Set when the in-band loop-up code is present at the receiver.
RCL
SR.0
Set when receiver has detected consecutive s set forth by CR4.2.
Cleared when the receiver detects 14 1s in a window of 112 clock
cycles.

LUP
IR.3
Set when in-band loop-up code is being received.
LDN
IR.2
Set when in-band loop-down code is being received.
TSCD
IR.1
Set when transmitter detects a short circuit.
LOTC
IR.0
Set when TCLK has not transitioned for approximately 5
ms.
Receive Level Indication: RL0 is the LSB and RL3 is the MSB of a 4-bit nibble that is used to indicate the inbound
signal strength. Convert the binary to decimal and multiply by -2.5dB. The result indicates the approximate
attenuation seen at the receiver inputs.
