Description
The DDI Mux supports a V.35 interface standard through its data interface port.
You can select V.35.
Select the transmission rate per channel (Fixed data lines) assigned to the
module.
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.
