Configuring the DDI Mux to work with the DTE
After you have assigned the lines to the data module, you need to configure the DDI Mux so it can
work with the DTE.
1
Click the keys beside Resources and Media Bay Modules .
2 Click the key of the Bus number for the Data Module portion of the DDI Mux.
3
Click the Data Module key and then click on Configuration .
4 Configure the setting to match the DTE you are connecting to the DDI Mux.
The following table describes the Data Module configuration settings.

DTE
The DDI Mux requires a timing signal to clock data transmitted by the DTE. This
signal can be supplied by the DTE or generated internally by the Business
Communications Manager. If the signal is generated by the DTE, the clock must
be locked to the frequency of the DDI Mux clock.
• Auto : The DDI Mux checks if the clock provided by the DTE is valid. If the
clock is valid, the module uses DTE clocking. If the DTE clocking is not valid,
the module uses its own internal clock (DCE).
• DCE : The internal TxSync clock is used to clock data.
• DTE : The TXClk clock provided by the DTE is used by the DDI Mux to clock
data.
Note : Use the DTE option only for diagnostic purposes.
For all options, the DTE must synchronize to the module.
