3. Set the DFXS Input Level and the Output Level required:
Signal Direction Level adjustment range Default setting
Input Level (L
i
) -9.0 dBr to +3.0 dBr in 0.5 dB steps +1.0 dBr
Output Level (L
o
) -9.5 dBr to +2.5 dBr in 0.5 dB steps -6.0 dBr
In the example shown below, the Customer Premises Equipment is a telephone connected to a
DFXS card.
The levels are set based on the system using a 0 dBr transmission reference point.
Output level
+1.0 dBr
Input level
-6.0 dBr
Output level
-6.0 dBr
Input level
+1.0 dBr
Transmission Reference point
0 dBr
DFXS Input Level setting
The telephone has a nominal output level of +1 dBr. To achieve a transmission reference point
transmit level of 0 dBr, the DFXS Input Level is set to +1 dBr (effective T pad loss of 1 dB).
DFXS Output Level setting
The telephone has a nominal input level of -6 dBr. With a transmission reference point received
level of 0 dBr, the DFXS Output level is set to -6 dBr (effective R pad loss of 6 dB).
