8 Modem Performance Characteristics

The curves presented in this data sheet define modem IC performance under a variety of line conditions

typical of those encountered over the Public Switched Telephone Network.

8.1 BER vs. SNR

This test represents the ability of the modem to operate over noisy lines with a minimum amount of data

transfer errors. Since some noise is generated in the best dial up lines, the modem must operate with the

lowest signal to noise ratio (SNR) possible.

Better modem performance is indicated by test curves that are closest to the BER axis. A narrow spread

between curves representing the four line parameters indicates minimal variation in performance while

operating over a range of typical operating conditions. A DPSK or QAM modem will exhibit better BER

performance test curves receiving in the low band (answer mode) than in the high band (originate mode).

8.2 BER vs. Receive Level

This test measures the dynamic range of the modem. Because signal levels vary widely over dial up

lines, the widest possible dynamic range is desirable. The SNR is held constant at the indicated values

as the receive level is lowered from a very high to a very low signal level. The width of the bowl of these

curves, taken at the BER break points is the measure of the dynamic range.
