When the CE3 interface is operating 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.
Examples
# Configure interface E3 2/0/0 to operate in unchannelized mode.
<Sysname> system-view
[Sysname] controller e3 2/0/0
[Sysname-E3 2/0/0] using e3

Parameters
detect: Enables/disables periodical alarm signal detection.
generate: Sends alarm signals, which can be AIS, RAI, idle, or FEBE for line state test. ais: Alarm
indication signal.
febe: Far end block error signal.
idle: Idle signal.
rai: Remote alarm indication signal.
Usage guidelines
At the startup of your device, periodical alarm signal detection is enabled on the CT3 interface. When
detecting LOS, LOF, or AIS signals, the interface sends RAI signals to its peer. Alarm state report for the
interface is real time; you may view that by performing the display controller t3 command.
