== OCTOI TDMoIP mode
|
|
|
|
Instead of providing a programmatic client interface (<<client>>) enabling
|
|
external applications timeslot-granular access to the data of a E1 line,
|
|
`osmo-e1d` also supports an entirely separate mode of operation:
|
|
_TDMoIP using the OCTOI (Osmocom Community TDMoIP) protocol_.
|
|
|
|
In this mode of operation, osmo-e1d acts as interface between an E1 line
|
|
and a remote system over UDP/IP. This allows you to transparently pass
|
|
an E1 line over an IP network such as the Internet.
|
|
|
|
`osmo-e1d` can operate either as client or as server for the OCTOI protocol.
|
|
|
|
=== osmo-e1d as OCTOI client
|
|
|
|
Below is an example configuration snippet for operating as an OCTOI client.

<1> we specify that Interface 0 Line 0 (I0:L0) of the icE1usb device with serial number dc697407e7881531 shall
|
|
be used in `e1oip` mode.

<2> we instantiate an OCTOI client to the remote IP 192.168.7.2 / UDP port 10013
|
|
<3> we specify to bind locally to INADDR_ANY and local UDP port 3333
|
|
<4> we specify the account/user name to tell the server is `foobar`
|
|
<5> we specify that this OCTOI client instance shall use the icE1usb device with the given serial number. This
|
|
must match the serial number used above when configuring the icE1usb line mode.
|

|
There can of course be any number of E1 interfaces/lines and clients; the example just shows one for clarity.
