T1-F interface can only work in framed mode, and it can randomly bind all time 
slots (time slots 1 through 24) into one channel set. T1-F interface has the rate of 
nx64kbps or nx56kbps, owns logical features of synchronous serial interface, and 
supports the data link layer protocols PPP, HDLC, Frame Relay, LAPB and X.25 as 
well as the network protocols IP and IPX.

T1-F interface configuration includes:

■

Enter the view of a specified interface

■

Set interface rate after binding operation

■

Set length/attenuation of transmission line

■

Set line code format

■

Set line clock

■

Set interface frame format

■

Enable or disable local/remote loopback

Unlike CT1/PRI interface, T1-F interface has no Controller view. The system identify 
a T1-F interface as a synchronous serial interface, so entering the view of T1-F 
interface is equivalent to entering the view of the corresponding serial interface.

Perform the following configuration in any view.

T1-F interface is sequenced based on the same numbering and are numbered 
together with the synchronous serial interfaces. 

When T1-F interface works in framed mode, time slot binding on the interfaces 
can be made according to user’s demands.

Perform the following configuration in T1-F interface view.

By default, binding operation will be done on all the time slots on T1-F interface.

Unlike CT1/PRI interface, only one channel set can be bound on a T1/F interface, 
and this channel set is associated with the current synchronous serial interface. On 
a CT1/PRI interface, however, multiple channel sets can be bound, and the system
