The UDS 2440 modem provides full-duplex 2-wire communications over either dial-up or private leased lines at data rates of up to 2400 bits per second (bps). It is compliant with CCITT standard V.22 bis and supports MNPTN levels 2 through 5.


  • Serial EIA-232 interface with Data Terminal Equipment
  • Communicates with DTE at rates of 9600,4800, 2400, 1200, 600, 300, and 110 bps
  • Speed conversion and buffering of data from the DTE Automatic rate and parity selection for the DTE
  • Multiple online and offline tests and diagnostics Configuration parameters stored in nonvolatile memory
  • LED indicators for communications status


The modem has the following features:.

Modulation compatible with the following standards:
