CL-T1/E1, IP over TDM Gateway

CL-T1/E1 is a broadband interface converter device which converts electrical and protocol conversion between data from Fractional E1/T1 to Ethernet 10/100BaseT interface with different E1/T1 configurations. CL-T1/E1 supports Fractional E1/T1 transparent and framed modes with different line codes plus line build-out (LBO) capability. This provides for the user with various Ethernet LAN services (Video Conferencing, Routing, etc.) through a single E1 /T1 connection.


  1. Support Fractional E1/T1 Transparent and Framed modes
  2. Bridge capabilities for Ethernet 10/100BASE-T interface
  3. IP Over SDH/PDH/ATM Network
  4. 6 LEDs for status monitoring
  5. DIP switches for configurations/settings
  6. Desktop and 19" rack (option)
