ISDN BRI S0 using 2-wire copper lines

Cost-effective plug & play Solution for ISDN Extension via 2-wire Copper Lines

  • Line: G.SHDSL according to ITU G.991.2
  • ISDN BRI S0 (ETSI I.430)
  • Switchable as NT or TE
  • Transparent transmission of voice and data
  • Distance: Up to 18 km
  • Cost-effective ISDN BRI S0 extension via G.SHDSL 2-wire Copper Lines

    The SPEED-ISDN EXTENDER is a cost-effective and easy-to-install solution for a transparent transmission of an ISDN BRI S0 interface over 2-wire copper lines achieving a distance up to 18 km. Voice, fax and data are transfered faultlessly by means of the transparent transmission. The installation is accomplished fast and easily without the need of special skills. A PC or terminal is not required for configuration.

  • Cost-effective ISDN PBX connection via 2-wire DSL Lines

    The ISDN interface can be adjusted to operate as TE or NT using a DIP switch. Thus a user can combine e.g. two PBXs or extend an existing ISDN S0 bus for ISDN telephones. The LEDs at the front indicate the active status of the ISDN and DSL interface. Optionally the ISDN S0 bus can be remotely powered with 40 volt. The product is available in an rugged aluminum housing which is EMC-safe. Additionally SPEED-ISDN EXTENDERs can be stacked.
