264 CHAPTER 16: FUNDAMENTAL CE3 INTERFACE CONFIGURATION COMMANDS
You need to set the national bit to 0 on an E3 interface only in some special
circumstances.
Related command: controller e3.
Example # Set the national bit to 0 on interface E3 2/0.
<Sysname> system-view
[Sysname] controller e3 2/0
[Sysname-E3 2/0] national-bit 0
using (CE3 interface view)
Syntax using { ce3 | e3 }
undo using
View CE3 interface view
Parameter ce3: Sets the CE3 interface to work in channelized mode.
e3: Sets the CE3 interface to work in unchannelized mode.
Description Use the
using command to configure the operating mode of the CE3 interface.
Use the undo using command to restore the default, that is, channelized mode.
Only when the CE3 interface is working in channelized mode can you configure
E1 lines.
When the CE3 interface is working in unchannelized mode, the system
automatically creates a serial interface numbered serial number/0:0 for it. This
interface operates at 34.368 Mbps and is logically equivalent to a synchronous
serial interface on which you can make other configurations.
Related command: controller e3.
Example # Configure interface E3 2/0 to operate in unchannelized mode.
<Sysname> system-view
[Sysname] controller e3 2/0
[Sysname-E3 2/0] using e3
