3.2.9 using (CE1/PRI Interface)

Syntax
using { ce1 | e1 }
View
CE1/PRI interface view
Parameter
None
Description
Using the using command, you can configure the operating mode of the CE1/PRI
interface.
By default, the CE1/PRI interface operates in CE1/PRI operating mode.
The CE1/PRI interface has two operating modes: E1 operating mode and CE1/PRI
operating mode.
When the CE1/PRI interface uses the E1 operating mode, it equals to an interface
with the data bandwidth of 2 Mbps, on which, no timeslots will be divided. Its logic
feature is the same as that of a synchronous serial interface.
When the CE1/PRI interface works in CE1/PRI operating mode, it is physically
divided into 32 timeslots numbered from 0 to 31. In which, timeslot 0 is used to
transmit the synchronizing information. This interface can be used as either a CE1
interface or a PRI interface.
After changing the operating mode of the CE1/PRI interface to the E1 mode, the
system
interface-number:0. In which, the interface-number starts from the largest serial
interface number plus 1.
Example
# Set the CE1/PRI interface to work in E1 operating mode.
