Loss Plan selection

The term card loss refers to the difference in signal power between the card
interface point and the digital 0 dB reference point. Card loss is the sum of the
loss designed into the circuitry plus the pad value selected.
Relative Input/Output Levels for a card with an A/D card loss of 2.0 dB and
a D/A loss of 6.5 dB would be
• Relative Input Level (Li) = 2.0 dBr
• Relative Output Level (Lo) = - 6.5 dBr
Loss Plan selection requires the selection of a predefined Loss Plan table in
LD 97. Two predefined modes of operation are available for Europe:
• European Telecommunication Standards Institute (ETSI) mode — uses
ETSI per-country input/output values as recommended in annexes to the
ETSI standards
• Existing mode — uses per-country values as designed for systems that
were in existence prior to the formulation of the ETSI standards.
One predefined mode of operation is also available for China.
LD 97 also enables the definition of Custom Loss Plan tables.
Table 17 shows the predefined Static Loss Plan tables applicable to the
various countries and operating modes.
