|---|---|---|---|
| 2 | |||
| 3 | The virtual E1 interface pair is used to test without any actual E1 hardware. It resembles the concept of a "virtual ethernet pair" (veth pair) |
||
| 4 | which is found in many containerized Linux applications of today. |
||
| 5 | |||
| 6 | The vpair implements two interfaces, each with a configurable number of lines. |
||
| 7 | |||
| 8 | Every line N of the first interface is 'virtually looped' to line N of the second interface in the pair. |
||
| 9 | |||
| 10 | This way two E1-using applications can talk back-to-back on a single system without any actual E1 interface cards or physical cabling. |
||
| 11 | |||
| 12 | In order to use a vpair, you must include the following line in your osmo-e1d.cfg: |
||
| 13 | <pre> |
||
| 14 | virtual-e1-pair 1 |
||
| 15 | </pre> |
||
| 16 | |||
| 17 | Where '1' is the number of lines the virtual interface shall have. |
