Setting Parameters for a VE1 Interface

Procedure

1. Run:

   system-view

   The system view is displayed.

2. Run:

   set workmode slot slot-id  e1t1 e1-voice

   The E1 interface board is configured as an E1 voice card.

   After this command is executed, the configured service takes no effect.

   After you using this command, the system displays a message asking 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. Otherwise, run the reset slot command to restart the E1 voice card.

3. Run:

   voice

   The voice view is displayed.

4. Run:

   port ve1 slotid/subcardid/portid

   The VE1 interface view is displayed.

5. Run:

   display voice port ve1 [ state slotid/subcardid/portid | slotid/subcardid/portid ]

   The signaling mode of the VE1 interface is displayed. If the signaling mode is not CCS, run the signal ccs command to change the signaling mode of the VE1 interface to CCS

   In H.248 AG mode, the signaling mode of the VE1 interface must be CCS.

6. (Optional) Run:

   access-mode { digital | direct }

   The access digital section mode is set.

7. (Optional) Run:

   crc4 enable

   The CRC4 check is enabled.

8. (Optional) Run:

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

   The CRC alarm threshold is set.

9. (Optional) Run:

   l2-monitor enable

   VE1 interface Layer 2 monitoring is enabled.

10. (Optional) Run:

    pcm-alarm

    The PCM alarm function is enabled.

11. (Optional) Run:

    impedance impedance-value

    The impedance of the VE1 interface is set.
