RC2324DPL

Product Summary

The RC2324DPL is a low power, V.22 bis 2400 bps data/fax modem data pump in a single VLSI package. The RC2324DPL is identical to the RC2324DPL except fax modes are not provided. In this document, all references to the device also apply to the RC2324DPL except for the fax modes and as otherwise noted. The modem operates over the public switched telephone network (PSTN), as well as on point-to-point leased lines. The modem supports data modes meeting the requirements specified in CCITT recommendations V.22 bis, V.22, V.23, and V.21, as well as Bell 212A and Bell 103.
