Procedure
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter T3 interface view. | controller t3 interface-number | N/A |
3. Create a serial interface for the T3 interface. | using t3 | By default, no serial interfaces are created for a T3 interface. |
4. (Optional.) Configure the interface to operate in FT3 mode and set the subrate. | ft3 subrate number | By default, the subrate is 44210 kbps. |
5. (Optional.) Configure the interface description. | description text | By default, the description of an interface is interface-name Interface. |
6. Set the clock mode. | clock { master | slave } | The default clock mode for the T3 interface is slave, which is line clock. |
7. Set the cable length. | cable feet | The default is 14.9 meters (49 feet). |
8. (Optional.) Set the loopback mode. | loopback { local | payload | remote } | By default, loopback is disabled. |
9. (Optional.) Configure alarm signal detection/sending. | alarm { detect | generate { ais | febe | idle | rai } } | By default, alarm signal detection is enabled and alarm signal sending is disabled. |
10. (Optional.) Restore the default settings for the T3 interface. | default | N/A |
11. (Optional.) Bring up the T3 interface. | undo shutdown | By default, a T3 interface is up. |
12. Return to system view. | quit | N/A |
13. Enter synchronous serial interface view. | interface serial number/0:0 | Make sure the synchronous serial interface is the one created for the T3 interface. |
14. Set the CRC mode. | crc { 16 | 32 | none } | The default is 16-bit CRC. |
