6. Set the keepalive transmission

interval.

timer-hold seconds The default is 10 seconds.

7. Set the intended bandwidth

for the BRI interface.

bandwidth bandwidth-value

By default, the expected

bandwidth (in kbps) is the interface

baud rate divided by 1000.

8. (Optional.) Restore the default

settings for the BRI interface.

Configuring a CE1/PRI interface

Overview

There are two TDM systems in the data communications system:

• E1 system—Recommended by ITU-T and widely used in Europe and P.R. China.

• T1 system—Recommended by ANSI and widely used in North American and Japan. (Japan

actually uses the J1 system. It is regarded as a T1 system due to the high level of similarity between

them.)

A CE1/PRI interface can operate in either E1 mode (also called non-channelized mode) or CE1/PRI

mode (also called channelized mode).

• A CE1/PRI interface in E1 mode is an interface of 2.048 Mbps data bandwidth, on which no

timeslots are divided. Its logical features are the same as those of a synchronous serial interface. It

supports link layer protocols such as PPP, FR, LAPB, and X.25 and the network protocols such as IP

and IPX.

• A CE1/PRI interface in CE1/PRI mode is physically divided into 32 timeslots numbered 0 to 31.

Timeslot 0 is used to transmit synchronizing information. This interface can be used as either a CE1

interface or a PRI interface.

{ When this interface is used as a CE1 interface, all the timeslots except timeslot 0 can be

randomly divided into multiple channel sets and each set can be used as an interface upon
