In the table, the clock ahead of “=” is the DTE clock and the one after is the
DCE clock.
Example
Set the synchronous serial interface working as DTE to use the clock selection
option DTEclk2.

code nrzi
Syntax
code nrzi
undo code
View
Synchronous serial interface view
Parameter
None
Description
Using the
code nrzi
command, you can set the digital signal coding format to
None-Return-to-Zero-Inverse (NRZI) for a synchronous serial interface.
Using the
undo code
command, you can restore the digital coding format of
the synchronous serial interface to NRZ.
The digital signal coding format defaults to NRZ on the synchronous serial
interface.
Example
Set the digital signal coding format to NRZI on the synchronous serial interface.

detect Syntax
1 Asynchronous serial interface
detect dsr-dtr
undo detect dsr-dtr
2 Synchronous serial interface
detect { dcd | dsr-dtr } undo detect { dcd | dsr-dtr }
View
Synchronous serial interface view, asynchronous serial interface view
Parameter
dsr-dtr
: Detects DSR and DTR signals of DSU/CSU.
dcd
: Detects the DCD signal of the DSU/CSU on the serial interface.
Description
Using the
detect
command, you can enable data carrier detection as well as
level detection on a serial interface. Using the
undo detect
command, you can
disable data carrier detection as well as level detection on the serial interface.
By default, serial interfaces are enabled to make data carrier and level
detection.
