V.32 DBM Technical Specifications

DBM option 0.7B
Full- or half-duplex data transmission via analog 2-wire dial network,
point-to-point
At 14.4 and 12 kbps: ITU-T V.32bis, 1800 Hz
At 4.8 and 9.6 kbps: ITU-T V.32, 1800 Hz
At 2.4 kbps: ITU-T V.22bis, 2400 Hz
2-wire analog (PSTN) line
Async or Sync rates: 14.4, 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 ITU-T 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)
2.4, 4.8, 9.6, 12, 14.4 kbps
If Call Setup is set for Callback or Password security, then the device is
compatible with a 3600 Series V.32 DBM only.
If Call Setup is set for Alarm or None, then any V.32 modem can be
used.
Also, V.22bis at 2.4 kbps can be used.
