This implements a TTCN-3 E1 Timeslot test port for Eclipse TITAN. Running on a (Linux) computer, it allows you to write TTCN-3 tests sending and receiving data on 64kBps E1 timeslots.
In order to interface both physical and virtual E1 lines, this port currently relies on osmo-e1d, the Osmocom E1 daemon . Adding back-ends for other drivers such as DAHDI should not be hard, if needed at a later point.
The timeslots can either be opened in RAW (transparent) 64kBps mode, or with a HDLC controller.
The idea of this module is to be able to write abstract test suites in TTCN-3 which interface IUT (Implementations under Test) over E1.
You can clone from the official titan.TestPorts.E1TS repository using
git clone https://git.osmocom.org/titan.TestPorts.E1TS
There's a cgit interface at https://cgit.osmocom.org/titan.TestPorts.E1TS/
This is still very much a Work-In-Progress, and hence there's no documentation yet, sorry.
