6.1 Coefficients and WinSLAC
Coefficient files were generated from the Microsemi WinSLAC software and used to program filters and configure
the Le9642. Microsemi provides a full set of coefficients for most world markets.
6.1.1 Coefficients
The standard Profile Wizard file for ZLR964222L reference design, contains coefficient sets for the following AC
profiles:
AC_FXS_RF14_600R_DEF (Default narrow band 600ohm)
AC_FXS_RF14_WB_600R_DEF (Default wide band 600ohm)
Line Module Default Coefficients were generated with the following parameters:
•600  termination
• Receive relative level = -6 dBr
• Transmit relative level = 0 dBr
• A-Law encoding (or µ-Law)
6.2 Narrowband Transmission Performance
The following graphs illustrate the narrowband (300 - 3400 Hz) transmission performance using a W&G PCM-4.
