| 17 | A T1/E1 crossover cable has pin 1 routed to pin 4 and pin 2 routed to pin 5. |
||
| 18 | |||
| 19 | |||
| 20 | Pin 1 will be the far left pin when holding the plug with the lock-tab facing away from you. Pin 8 will then be the far right pin. |

| 22 | |||
| 23 | 1 <-> 4 |
||
| 24 | 2 <-> 5 |
||
| 25 | |||
| 26 | The other pairs of the cable should all be routed straight through (the T568A standard may be used as an example for this). |
||
| 27 | |||
| 28 | |||
| 29 | This is not compatible with an Ethernet cross-over cable which swaps 1<->3 and 2<-> 6 (and optionally 4 <->7 and 5 <-> 8). |
