In addition, when the Mode field change is saved by pressing the Enter or Return

 

 

 

 

key, the MPU will instruct the DS3 MUX to drop and insert the selected circuit.

 

 

 

 

 

 

 

 

 

 

MONE

Non-intrusive monitor access to the A pair.

 

 

 

 

 

 

 

 

 

 

MONF

Non-intrusive monitor access to the B pair.

 

 

 

 

 

 

 

 

 

 

SPLTA

SPLTA mode indicates a split in the A transmission path

 

 

 

 

 

with a TSG (Test Signal Generator) connected in the F

 

 

 

 

 

direction, and an SPD (Signal Presence Detector) connected

 

 

 

 

 

to the signal from the E direction.

 

 

 

 

 

 

 

 

 

 

SPLTB

SPLTB mode indicates a split in the B transmission path

 

 

 

 

 

with a TSG connected in the E direction, and an SPD

 

 

 

 

 

connected to the signal from the F direction.

 

 

 

 

 

 

 

 

 

 

SPLTE

SPLTE mode indicates a split in both the A and B

 

 

 

 

 

transmission paths. An SPD is connected to the line incoming

 

 

 

 

 

from the E direction and a TSG is connected to the line

 

 

 

 

 

outgoing to the E direction. The line outgoing in the F

 

 

 

 

 

direction is connected to a QRSS source, and the line

 

 

 

 

 

incoming from the E direction is terminated by the nominal

 

 

 

 

 

characteristic impedance of the line.

 

 

 

 

 

 

 

 

 

 

SPLTF

SPLTF indicates a split in both the A and B transmission paths

 

 

 

 

 

with a TSG connected to the line outgoing to the F direction,

 

 

 

 

 

and an SPD connected to the line incoming from the F

 

 

 

 

 

direction. The line outgoing in the E direction is connected to

 

 

 

 

 

a QRSS source, and the line incoming from the E direction is

 

 

 

 

 

terminated by the nominal characteristic impedance of the line.

 

 

 

 

 

 

 

 

 

 

SPLTEL

SPLTEL indicates a split in both the A and B paths and connects

 

 

 

 

 

an SPD to the line incoming from the E direction and a TSG to

 

 

 

 

 

the line outgoing in the E direction similar to SPLTE mode. The

 

 

 

 

 

signal in the F direction is looped back.
