Getting Started¶

This page is a work-in-progress documenting what you need to do to get connected to the Community_TDMSS7_Network using an icE1usb.

Required Hardware¶

• icE1usb hardware (contact sales@sysmocom.de for an OCTOI community special price of EUR 75)
• GPS antenna with SMA male plug (not included)
• Some equipment with an E1 interface which you want to connect to the community network. Typically this is a PBX with E1/PRI/S2M upstream connection.
• Some computer running Linux with a USB host controller to connect the icE1usb to. Note: Many USB XHCI host controllers suffer from bugs, restricting operation to only one of the two E1 ports, see Isochronous_USB_Issues for details. If you have a system with UHCI/OHCI/EHCI, use that.

Major steps required for setup¶

1. Installing latest gateware and firmware into the icE1usb
2. building + installing the laforge/e1oip branch of osmo-e1d
3. requesting a connection with the OCTOI hub
4. creating a config file for osmo-e1d
5. possibly adding a port forward in your router

Installing latest gateware and firmware into the icE1usb¶

Please follow the instructions of the icE1usb user manaul

Firmware is available from https://downloads.osmocom.org/binaries/icE1usb/firmware/all/

You will need dfu-util for performing the USB device firmware upgrade. Most distributions should have a package for this.

building + installing the laforge/e1oip branch of osmo-e1d¶

As the protocol is still under fluctuation, it is not yet part of the master branch and hence not available as a binary package yet. You will need to build osmo-e1d frm source.

dependencies¶

You will need

• build-essential (gcc, binutils, make, ...)
• autotools (autoconf, automake)
• libtool
• pkg-config
• talloc
• libosmocore
• libusb-1.0

If using distribution packages, make sure you install the development packages (e.g. libtalloc-dev).

building¶

autoreconf -fi
./configure
make

installation (optional)¶

you can run osmo-e1d from the build directory, there's no strict need to install it.

If you do install it using the below instructions, the binary will be in /usr/local/bin or whatever is configured at configure time.

make install

requesting connection¶

Please contact laforge with your IP address and port number. Right now the protocol does not yet support dynamic IP addresses.

creating a config file¶
