136CHAPTER 10: CONFIGURING WAN INTERFACE

■Bind the interface to be a pri set

■Set the length/attenuation of the transmission cable

■Set the line code format

■Set line clock

■Set frame format

■Enable/disable internal loopback/external loopback

1Enter the view for a specified interface

In system view, use the following command to enter the view of a specified CT1/PRI interface.

Table 137 Enter the view of a specified interface

Operation	Command

2Bind the interface to be channel sets

Perform the following configurations in CT1/PRI interface view.

Table 138 Bind the interface to be channel sets

Operation	Command
Bind the timeslots of CT1/PRI interface to a	channel-set set-number
channel set	timeslot-list range [ speed { 56
	64 } ]
Remove binding timeslots to form channel	undo channel-set set-number
sets

The timeslots can be bind to form up to 24 on a CT1/PRI interface.

The CE1/PRI interface can be bound to be channel sets only when it is enabled to operate in CE1/PRI mode through the using ce1 command.

Only one timeslot binding mode is supported on one CT1/PRI interface at one time, that is, the interface can only be bound into either channel sets or a pri set in that period.

After binding the interface to be channel sets, the system will automatically create a Serial interface numbered serial number:set-number. This interface has the same logic feature as that of a synchronous serial interface, and can be treated as a synchronous serial interface for further configurations.

Perform the following configuration in all views.

	number:set-number

The following is to be set:

■Operating parameters of data link layer protocol, such as PPP, Frame Relay, LAPB or X.25.

■IP address

■The operating parameters of the standby center need to be set when the interface serves as the main interface or standby interface of the standby center.
