1.1. Selection Guide
Tables 1 through 3 list the modulations, protocols, carriers, tones and interface modes supported by the Si2494/39
and Si2493/57/34/15/04 ISOmodem family. The Si2493 supports all modulations and protocols from Bell 103
through V.92. The Si2457 supports all modulations and protocols from Bell 103 through V.90. The Si2434 supports
all modulations and protocols from Bell 103 through V.34. The Si2415 supports all modulations and protocols from
Bell 103 through V.32bis. The Si2404 supports all modulations and protocols from Bell 103 through V.22bis.
*Note: With the Si3018 DAA only.
*Note: The Si2494/93/57/39/34/15/04 family allows any supported protocol combined with any modulation.
