136 CHAPTER 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
1 Enter 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
2 Bind the interface to be channel sets
Perform the following configurations in CT1/PRI interface view.
Table 138 Bind the interface to be channel 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.
Table 139 Enter the synchronous serial interface view
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.
