Unlike CE1/PRI interface, E1-F interface has no Controller view. The system identify 
an E1-F interface as a synchronous serial interface, so entering the view of E1-F 
interface is equivalent to entering the view of the corresponding serial interface.

Perform the following configuration in any view.

E1-F interface is sequenced based on the same numbering and are numbered 
together with the synchronous serial interfaces. 

E1-F interface can work in both unframed and framed modes.

Perform the following configuration in E1-F interface view.

By default, E1-F interfaces work in framed mode.

When E1-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 E1-F interface view.

By default, binding operation will be done on all the time slots on E1-F interface.

Unlike CE1/PRI interface, only one channel set can be bound on an E1-F interface, 
and this channel set is associated with the current synchronous serial interface. On 
a CE1/PRI interface, however, multiple channel sets can be bound, and the system
