RC9696

The Rockwell RG9696 is a 14400 bps 2-wire, fullduplex, synchronousiasynchronous, V.32 bis modem data pump module. RC9696/14 operates over the public switched telephone network (PSTN) through the appropriate line termination. The modem satisfies the requirements specified in CCITT recommendations V.32 bis, V. 32, V.17N.33, V.29, V.27 ter, V.22 bis, V.22, V.23, and V.21 ; is compatible with Bell 212A and Bell 103 modems; and supports Group 3 facsimile. The RC9696/14 can operate at 14400, 12000, 9600, 7200, 4800, 2400, 1200, 600, or 300 bps depending upon the selected configuration. The RC9696/14 is designed for use in high speed data applications. User programmable features allow the modem operation to be tailored to support a wide range of functional requirements. The dual-in-line pin (DIP) connection allows direct installation onto a host module. 111e modem's small size (less than 13 square inches), low power consumption, Seriallparallel host interface, and DIP connection simplify system development and reduce system production cost. Detailed hardware and software int rface information is described in the RC9696.(14 and RC1496f14 Modem Designer's Guide (Order No. 856).

The features of RG9696 can be summarized as (1)2-wire full-duplex compatibilities: CCITT V.32 bis, V.32, V.22 bis, V.22, V.23, and V.21, BeIl 212A and 103; (2)2-wire half-duplex compatibilities: -CCITT V.17N.33, V.29, V.27 ter, and V.21 channel 2; (3)group 3 (G3) facsimile sendlreceive compatible; (4)parallel synchronous; (5)serial synchronous; (6)serial asynchronous up to 9600 bps; (7)Trellis-coded modulation (TOM) at 14400, 12000, 9600, and 7200 bps; (8)programmable near and far end echo cancellation; (9)bulk: delay for satellite transmission; (10)auto-dial and auto-answer capability; (11)TTL and GMOS compatible DTE interface: CCITT V.24 (RS-232-O) (datalcontrol), microprocessor bus(data/ conliguration/ controlj; (12)dynamic Range: -43 dBm to 0 dBm; (13)programmable compromise equalizer in transmitter; (14)automatic adaptive equalizer in receiver; (15)diagnostic capability; (16)V.13 signalling; (17)V.54 inter-DOE signalling; (18)V.54 local analog and remote digital loopbaok; (19)small size: 82 mm x 100 mm (3.23 in. x 3.94 in.); (20)low power consumption: 1.9W (typical).

The absolute maximum ratings of RC9696 are (1)operating temperature: 0°C to + 70°C (32°F to 158°F); (2)storage temperature: -40°C to + 80°C(-40°F to 176°F); (3)relative humidity up to 90% noncondensing, or a wet bulb temperature up to 35°C, whichever is less.
