TDM Bus Clock Settings
In a traditional TDM service network such as PSTN, both ends of the TDM connection must be synchronized. If synchronization is not achieved, voice frames are either dropped (to prevent a buffer overflow condition) or inserted (to prevent an underflow condition). In both cases, connection quality and reliability is affected.

■ | Internal clock (see Configuring Internal Clock as Clock Source) |
When the device is used in a ‘non-span’ configuration, the internal device clock must be used (as explained above).
