4 Channel Ethernet/IP over T1/E1 Multiplexer

Rollover or Touch for Expanded View. Scroll to Zoom.


The TC8619 Ethernet-over-T1/E1 Gateway allows the user to extend Ethernet backhaul applications to remote locations over existing TDM Telecom infrastructure. It converts the Ethernet data into framed T1/E1 format for transmission over T1/E1 links, and the modules are used in pairs.

  • Fast Ethernet Transport over Framed T1 or E1
  • IEEE 802.1p QoS with Four Queues
  • Strict or Weighted Round Robin Priority Scheduling
  • Extreme Temp (-40°C to +80ºC) Optional
  • Built-in Power Redundancy
  • Meets or Exceeds IEC 61850-3, IEEE 1613 & NEMA TS-2 Standards
  • Member of the Mini Channel Bank Product Family

The TC8619 performs store-and-forward of frames with Ethernet traffic conditioning and bridging functions at wire speed, fully utilizing the TDM circuit.


  • Bridging Ethernet LANs over Existing T1/E1 Telecom Network
  • Extending Ethernet Networks by Utilizing TDM Telecom Infrastructure (i.e. T1/E1 Landline, or T1/E1s/PDH/SDH Microwave Carrying T1/E1)
  • Demarcation Between the Carrier’s and Customer’s Networks
  • Bonded Transparent LAN Service
