compatible with AT&T, US SPRINTr, and MCIr using DataPatht 2-wire
switched access to a local exchange carrier (LEC) or an interexchange

12.0, 9.6, 9.2, 8.4, 7.2, 4.8, 4.4, 4.0, 2.4, 2.0, and 1.2 kbps
Other asynchronous rates (e.g., 150, 300, 600, and 1800 bps) can be
obtained through oversampling
Asynchronous rates support CCITT V.14 extended rate range at
8 to 12 bits per character
, including the
start
and
stop
bit (+2.3,
–2.5
percent overspeed/underspeed compensation at 10 bits per character)
DATA RATES 56 kbps
(Note that the 2-wire Switched 56 DBM or 3600 Series DBM-D
uses proprietary rate adaption to support data rates of less than
56 kbps.)
