Clear the controller counter for a
CE1 interface.

Configuring an E1-F interface

E1-F interfaces, which are fractional E1 interfaces, are simplified CE1 interfaces. They are a cost-effective
alternative to CE1 interfaces where E1 access does not need multiple channel sets.
An E1-F interface operating in framed mode can only bind timeslots into one channel set. A CE1
interface can group and bundle timeslots randomly into multiple channel sets.
An E1-F interface can operate in either framed (the default) or unframed mode.
When an E1-F interface is working in unframed mode, it is a non-timeslot interface with 2048 kbps of
data bandwidth. It is logically equivalent to a synchronous serial interface where you can configure PPP,
HDLC, or FR at the link layer and IP at the network layer.
When an E1-F interface is working in framed mode, it is physically divided into 32 timeslots numbered
0 through 31. Except timeslot 0 used for transmitting synchronization information, all other timeslots can
randomly form one channel set. The rate of the interface is n × 64 kbps and its logical features are the
same as those of a synchronous serial interface where you can configure PPP and FR at the data link layer
and IP at the network layer.
