RC96V24DP
Single Device Data/Fax Modem Data Pump
The Rockwell RC96V24DP 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
RC96V24DP except fax modes are not provided. In this document, all
references to the RC96V24DP 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.
The modem supports fax modes meeting the requirements specified in
CCITT V.29, V.27 ter, and V.21 channel 2 synchronous.
Internal HDLC support eliminates the need for an external serial input/output
(SIO) device or comparable functions in the host controller in products
incorporating error correction and T.30 protocols.
The modem includes two CMOS VLSI functions – a digital signal processor
(DSP) and an integrated analog function (IA). The RC96V24DP integrates these
functions into a single 68-pin plastic leaded chip carrier (PLCC).
Detailed hardware and software interface information is described in the
Designer's Guide (Order No. 822).
