Osmocom icE1usb - E1 interface for USB

€285.60*

Product number: icE1usb-kit
Product information "Osmocom icE1usb - E1 interface for USB"

The icE1usb is ab E1 adapter with a USB interface. It can be used to attach to circuit-switched primary-rate E1 circuits used in traditional/legacy telecom environments.

Today, E1 circuits can primarily be found in the context of cellular networks; whether to carry A-bis back-haul, Gb over Frame Relay, A over TDM interfaces or any classic circuit SS7 signaling.

Those few other E1 adapters available on the market are typically PCI / PCIe cards, which constrains their usage to larger servers with the appropriate slots. Contrary to that, icE1usb connects via USB to the computer, allowing for use cases like

  • E1 attached to a Laptop computer
  • E1 attached to embedded Single Board Computers like for example Beagleboard, Raspberry Pi, Intel NUC or any other platform with a USB host controller.

The icE1usb has two physical E1 ports.  However, the use of two simultaneous ports is border-line of what full-speed USB can physically do, and it only works in very specific constellations with very specific host controllers, software, etc.  So in general, we now advertise it as a single-port device.  If you can make the second port work for you: Great.  If not: You have been warned!

Open Source Hardware

 The icE1usb is 100% Open Source Hardware (OSHW). This includes

  • mechanical cad files
  • schematics, circuit board layout, bill of materials
  • Verilog/HDL sources for the gateware
  • C source code for the firmware running on the PicoRV32 softcore in the FPGA
  • C source code for the (Linux) drivers on the host computer
