CE1/PRI Interface 133

■The rules for address translation or packet filtering need to be set if the firewall is to be set up on the interface.

For more details, refer to the related sections of this manual.

4Bind an interface to be a pri set

Perform the following configurations in CE1/PRI interface view.

Table 130 Bind the interface to be a pri set

Operation	Command
Bind the timeslots of CE1/PRI interface to be a	pri-set [ timeslot-list range ]
pri set
Remove binding timeslots to be a pri set	undo pri-set

Timeslots on a CE1/PRI interface can be bound to be only one pri set.

When binding an interface to be a pri set, timeslot 16 on a CE1/PRI interface is used as the D channel and the other timeslots are used as B channels. As for the CE1/PRI interface, timeslot 0 will be excluded since it is used to transmit the synchronous information. If no timeslots are specified to be bound, all the timeslots will be bound to form an interface similar to an ISDN PRI interface of 30B+D. If only timeslot 16 is bound, the binding activity will fail.

The CE1/PRI interface can be bound to be a pri set 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 CE1/PRI interface at one time, that is, the interface can only be bound into either channel sets or a pri set.

After the interface is bound to be a pri set, the system will automatically create a Serial interface numbered serial number:15. This interface is logically equivalent to an ISDN PRI interface, and hence you can further configure it.

Perform the following configuration in all views.

Table 131 Enter the ISDN interface view

Operation	Command
Enter the ISDN interface view	interface serial number:15

The following is to be set:

■BDR operating parameters

■Encapsulate the data link layer protocol PPP, its authentication parameters and etc.

■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.

■Configure the firewall if necessary.

5Set the line code format

A CE1/PRI interface supports two types of line code formats: ami format and hdb3 format.

Perform the following configurations in CE1/PRI interface view.
