I
Local Loop-back - Channel (n):
This input pin along with RLB_(n) dictates which Loop-Back mode Chan-
nel (n) is operating in.
A "High" on this pin with RLB_(n) set to "Low" configures Channel (n) to
operate in the Analog Local Loop-Back Mode.
A "High" on this pin with RLB_(n) also being set to "High" configures
Channel (n) to operate in the Digital Local Loop-Back Mode.
NOTE: This pin is ignored and should be tied to GND if the XRT73L03B
is going to be operating in the HOST Mode.

I
Remote Loop-Back - Channel (n):
This input pin in conjunction with LLB_(n) dictates which Loop-Back
mode Channel (n) is operating in.
A "High" on this pin with LLB_(n) being set to "Low" configures Channel
(n) to operate in the Remote Loop-Back Mode.
A "High" on this pin with LLB_(n) also being set to "High" configures
Channel (n) to operate in the Digital Local Loop-Back Mode.
NOTE: This pin is ignored and should be tied to GND if the XRT73L03B
is going to be operating in the HOST Mode.

LOSMUTEN
I
MUTE-upon-LOS Enable Input (Hardware Mode):
This input pin is use to configure the XRT73L03B, while it is operating in
the Hardware Mode, to Mute the recovered data via the RPOS_(n),
RNEG_(n) output pins whenever one of the Channels declares an LOS
conditions.
Setting this input pin “High" configures all Channels to automatically pull
the RPOS_(n) and RNEG_(n) output pins “Low” whenever it is declaring
an LOS condition, thereby Muting the data being output to the Terminal
Equipment.
Setting this input pin "Low" configures all Channels to NOT automatically
Mute the recovered data whenever an LOS condition is declared.
NOTES: This pin is ignored and should be tied to GND if the XRT73L03B
is going to be operating in the HOST Mode. This pin is internally pulled
"Low".
