Fax data transmission to mobile radios, using nor- mal analog audio channels, can encounter a problem with the base station limiter and splatter filter resulting in poor fax data transmission in the "outbound landhne to mobile, direction (lower success rate and slower data speeds). This problem is inherent in any interconnect system interface because of the desire to optimize voice transmission, which has a different power spectral den- sity than data, and the use of a limiter and splatter filter in the base station to meet FCC requirements of occu- pied bandwidth and adjacent channel splatter.
