1.0 Functional Description

1.1 Overview

The Rockwell RC96V24DP is a low power, V.22 bis 2400 bps data/fax modem

data pump in a single VLSI package.

1.2 Technical Specifications

1.2.1 Configurations And Rates

The selectable modem configurations, along with the corresponding signaling

(baud) rates and data rates, are listed in Table 1-1 (CONF bits).

Note: Bit names refer to control or status bits in DSP interface memory which

are set or reset by the host processor (see Table 3-1 and Table 3-2).

1.2.2 Data Encoding

The data encoding conforms to CCITT recommendations V.29, V.27 ter, V.22 bis,

V.22, V.23, or V.21, or to Bell 212A or 103, depending on the selected

configuration.

1.2.3 Tone Generation

Answer Tone: A CCITT (2100 ±15 Hz) or Bell (2225 ±10 Hz) answer tone can

be generated.

Guard Tone: A1800 ±20 Hz guard tone can be generated (enabled by the GTE

bit).

DTMF Tones: Dual tone multi-frequency (DTMF) tones can be generated with a

frequency accuracy of ±1.5%.

User Defined Tones: A user-defined single or dual tone can be generated from

200 Hz to 3000 Hz ±5 Hz.
