tion
DCEclk3 TxClk = Line, RxClk = Line.
In the table, the clock preceding the equal sign (=) is the DCE clock and the one that follows is the clock
signal source.
Examples
# Set the synchronous serial interface working as DTE to use the clock selection option dteclk2.
<Sysname> system-view
[Sysname] interface serial 2/0/0
[Sysname-Serial2/0/0] clock dteclk2
code
Use code to configure the digital signal coding format on the synchronous serial interface.
Use undo code to restore the default.
Syntax
code { nrz | nrzi }
undo code
Default
The digital signal coding format t is NRZ.
Views
Synchronous serial interface view
Default command level
2: System level
Parameters
nrz: Sets the digital signal coding format to nonreturn to zero (NRZ).
nrzi: Sets the digital signal coding format to nonreturn to zero inverted (NRZI).
Examples
# Set the digital signal coding format to NRZI on synchronous serial interface 2/0/0.
<Sysname> system-view
[Sysname] interface serial 2/0/0
[Sysname-Serial2/0/0] code nrzi
crc
Use crc to set the CRC mode for a synchronous serial interface.
Use undo crc to restore the default.
Syntax
crc { 16 | 32 | none }
undo crc
