212CHAPTER 12: FUNDAMENTAL CE1/PRI INTERFACE CONFIGURATION COMMANDS

Example # Clear the controller counter for CE1/PRI interface E1 2/0.

<Sysname> reset counters controller e1 2/0

using (CE1/PRI interface view)

Syntax	using { ce1 e1 }
	undo using
View	CE1/PRI interface view
Parameter	ce1: Sets the interface to operate in CE1/PRI mode.
	e1: Sets the interface to operate in E1 mode.
Description	Use the using command to configure the operating mode of the CE1/PRI
	interface.
	Use the undo using command to restore the default, that is, CE1/PRI mode.
	A CE1/PRI interface can work in either E1 mode (non-channelized mode) or
	CE1/PRI mode (channelized mode).
	In E1 mode, the interface equals a 2 Mbps interface without timeslot division. Its
	logical features are the same like those of a synchronous serial interface. In
	CE1/PRI mode, it is physically divided into 32 timeslots numbered 0 through 31,
	where timeslot 0 is used for FSC. This interface can work as either a CE1 interface
	or a PRI interface.
	After you set the CE1/PRI interface to work in E1 mode, the system automatically
	creates a serial interface numbered serial interface-number:0, where
	interface-numberrepresents the number of the CE1/PRI interface.
Example	# Set CE1/PRI interface E1 2/0 to work in E1 mode.
