4-Wire Switched 56 DBM Technical Specifications

Full- or half-duplex data transmission via 56 kbps switched services
compatible with AT&T, MCIr, and US SPRINTr using 4-wire switched
access to a local exchange carrier (LEC) or an inter-exchange carrier
(IEC)
A dedicated 4-wire access or a local exchange carrier 4-wire switched
access
Async or Sync rates: 56, 48, 38.4, 32, 28.8, 19.2, 18.8, 18.0, 16.8, 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)
56 kbps (Note that the 4-wire Switched 56 DBM or 3600 Series DBM-S
uses proprietary rate adaption to support data rates of less than
56 kbps.)
If Call Setup is set for Callback or Password security, then the
device is compatible with a 3600 Series Switched 56 DBM only.
If Call Setup is set for Alarm or None, then any Switched 56 kbps
terminal interface unit (TIU) can be used.
8-pin modular jack, USOC SJA56
(One or two) 50-pin connector, USOC SJA57
