Setting Parameters for Physical Voice Interfaces

1

Enter the system view.

2

Enter the voice view.

-

3

Enter the FXS interface view.

port fxs slotid/subcardid/portid

By default, the region identifier is China mainland.

4

Set physical attributes for the FXS interface.

-

5

Set electrical attributes for the FXS interface.

2

Enter the voice view.

3

Enter the FXO interface view

port fxo slotid/subcardid/portid

-

4

Set the gain.

gain { send sendgain-value | receive recvgain-value }

If the RBT played for the caller through the FXO interface is loud, the FXO interface may fail to detect the busy tone from the caller. Therefore, if the caller hangs up before the call is answered, the called user still hears the ring tone for a period. This problem can be solved by adjusting the send gain on the FXO interface.

5

Set the impedance.

impedance { dc value | ac value }

-

6

Set the ring current.

ring { minimum-duration min-duration-value | maximum-interval max-interval-value | frequence frequence-value | ac-amplitude ac-amplitude-value | offset offset-value }

-

7

Set the feed.

feed { maximum-voltage max-vol-value | minimum-voltage min-vol-value | maximum-current max-current-value | minimum-current min-current-value }

2

Configure the working mode of the 2BST interface card.

set workmode slot slot-id bri bri-voice { nt-mode | te-mode }

When the BRA interface connects to an ISDN phone, set the working mode of the 2BST interface card to nt-mode. When the BRA interface connects to an ISDN network, set the working mode of the 2BST interface card to te-mode.

3

Enter the voice view.

4

Enter the BRA interface view.

port bra slotid/subcardid/portid

-

6

Enable BRA interface Layer 2 monitoring.

l2-monitor enable

-

7

Set the working mode.

work-mode { p2p | p2mp }

-

8

Enable remote power supply.

remote-power enable

-

9

Enabled the alarm function.

alarm enable

-

1

Enter the system view.

2

Configure the E1 card as the E1 voice card.

set workmode slot slot-id e1t1 e1-voice

After this command is executed, the configured service is invalid. The system asks you whether to reset the E1 voice card. If you enter Y, the system resets the E1 voice card to make the configuration take effect. If the system does not reset the E1 voice card, run the reset slot command to reset the E1 voice card.

3

Enter the voice view.

-

4

Enter the VE1 interface view.

port ve1 slotid/subcardid/portid

-

5

Set the signaling mode.

signal { ccs | cas }

When the VE1 interface is bound to a PRA trunk, configure common channel signaling (CCS) on the VE1 interface. When the VE1 interface is bound to an E1R2 trunk, configure channel associated signaling (CAS) on the VE1 interface.

By default, a VE1 interface uses the CCS mode.

6

Set the access digital section mode.

access-mode { digital | direct }

-

7

Enable the CRC4 function.

crc4 enable

-

8

Set the CRC alarm threshold.

crc-alarm-threshold { es es-threshold | cses cses-threshold | dm dm-threshold }

-

9

Enable VE1 interface Layer 2 monitoring.

l2-monitor enable

-

10

Enable the PCM alarm function.

pcm-alarm

-

11

Set the impedance of the VE1 interface.

impedance impedance-value

-

Verify the FXS interface configuration.

display voice port fxs [ slotid/subcardid/portid ]

The parameter values in the command output are consistent with the settings.

Verify the FXO interface configuration.

display voice port fxo [ slotid/subcardid/portid ]

Verify the BRA interface configuration.

display voice port bra [ slotid/subcardid/portid ]

Verify the VE1 interface configuration.

display voice port ve1 [ slotid/subcardid/portid ]
