DC2000 Application Diagram

  • Cost effective E1 G.703 2.048 Mbps interface
  • EIA530, V.35 or X.21 port for router connection
  • Diagnostics give peace of mind
  • Easy to install & maintain
  • Integral power supply (110/220-250V AC switchable or -48V DC versions)
  • External alarm relay port
  • Compact modem style unit, built to European standards

Data is carried on the E1 line as unstructured payload. In addition to providing very cost-effective interfacing, the DC2000 provides a test and troubleshooting facility with Remote loop and Local loop test functions as well as a Remotely activated loop test which often eliminates the need for an engineer to visit a remote site for diagnosis of problems.

LEDs on the units front fascia panel provide information on the DC2000's operational and test status.

AC mains supply is switchable on the rear panel between 240 VAC and 110 VAC. DC models are also available for a supply voltage of -48VDC.
