Like this: Like Loading When independent clocking is configured, the port supports only data applications and voice applications are not supported. However, other ports that do not have independent clocking enabled but use the same controller still support voice applications.

Port 1 enables independent clocking. When using the clock source line independent and no clock source line independent commands, the channel group must be removed from the configuration. This section provides information about the following:. The drop and insert feature enables the removal of DS0 time slots from one E1 interface and insertion into time slots of the other E1 interface.

This feature is available in VWIC applications. If you configure drop and insert, be sure that the E1 framing under the controllers involved the tdm-groups configuration location is the same. If you use different frame types, the signaling bits may not be read properly.

This failure occurs during the drop of a channel from one controller and insertion into a channel from another controller. Drop and insert time slots do not need to be contiguous. Note For enabling the Drop and Insert in vwic3, run the network clock participate command on a particular wic slot.

For instance, network-clock-participate wic 0. You do not need do this in vwic2 because in vwic2 the internal PLL per module will synchronize clock source line and clock source internal. The internal PLL is removed from vwic3 to provide more flexibility. Router config-voicecard codec complexity flex. Specifies the codec complexity based on the codec standard you are using.

Note High-complexity codecs support lower call density than do medium-complexity codecs. Note All medium-complexity codecs are supported in high-complexity codecs. Shut down the voice port associated with the controller.

Enter the voice-card slot command, and then change the codec complexity. Note This procedure to change codec complexity applies only to T1 and E1 controllers. This is not valid for analog voice ports. Enters controller configuration mode for the VWIC. Router config-controller clock source line independent. If it is down, then the internal port generates its own clock. Port 0 is the default primary clock source, and port 1 is the default secondary clock source and is loop-timed.

With independent clocking enabled, this dependency no longer exists, so the independent keyword means that both ports can be independently clocked. Already a Member?
