Setting operating mode of the CE3 interface
Setting operating mode of a CE3 interface includes the tasks of setting it to work
in channelized or unchannelized mode and setting its E1 lines to work in E1 or
CE1 mode.

CE1 mode.
Perform the following configuration in CE3 interface view.
By default, CE3 interfaces work in channelized mode.
When an E3 interface is working in unchannelized mode, the system automatically
creates a serial interface numbered
creates a serial interface numbered
serial number / 0:0
for it. This interface
operates at 34.368 Mbps and has the same logic features of a synchronous serial
interface on which you can make other configurations.

When the E3 interface is working in channelized mode, you can set the operating

By default, E1 lines work in CE1 mode.
When an E1 line is working in unframed (E1) mode, the system automatically
creates a serial interface numbered

When an E1 line operates at framed (CE1) mode, you can bundle the timeslots on
