Configuring a BSV interface
A BSV interface can generate basic rate interfaces (BRIs) and logical digital voice interfaces.
BRI—Has the same logical characteristics as an ISDN BRI but can be used only for voice transmission. You can configure ISDN parameters on a BRI interface.
Logical digital voice interface—Can be configured with voice commands. A logical digital voice interface has two subinterfaces, which correspond to the two B channels. You cannot configure commands on the subinterfaces, but you can use the display voice subscriber-line line-number.subnumber command to view the call state of a subinterface.
To configure a BSV interface:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter BRI interface view. | interface bri interface-number | N/A |
3. (Optional.) Configure a description for the interface. | description text | The default is interface name Interface. |
4. (Optional.) Enable loopback detection for B channels. | loopback { b1 | b2 | both } | By default, loopback detection is disabled. |
5. (Optional.) Configure the expected bandwidth of the interface. | bandwidth bandwidth-value | The default is 0 kbps. |
6. Set the MTU of the interface. | mtu size | The default is 1500 bytes. |
7. Set the polling interval for the interface. | timer-hold seconds | The default is 10 seconds. |
8. (Optional.) Restore the default settings for the interface. | default | N/A |
9. Bring up the interface. | undo shutdown | By default, a BRI interface is up. |
10. (Optional.) Activate the interface. | activate | By default, a BRI interface is not activated. |
