In a pri-set formed by bundling the timeslots of a CT1/PRI interface, timeslot 24 is
used as D channel for signaling transmission, and other timeslots as B channels for
data transmission. All the timeslots can be randomly bundled into a pri-set (as a D
channel, timeslot 24 is automatically bundled). The logic features of this pri-set will
be the same as those of an ISDN PRI interface. If no timeslots are specified for
bundling, all the timeslots will be bundled into an interface similar to an ISDN PRI
interface in the form of 23B+D.
The system will automatically create a serial interface after the operation of
timeslot bundling on the interface. This serial interface has the same logic features
as an ISDN PRI interface. The serial interface is numbered in the form of serial
number:23, in which number starts from the maximum serial interface number
plus 1.
Only one timeslot bundling mode can be supported on one CE1/PRI interface
during a time period. In other words, this command cannot be used together with
the channel-set command.
For a related command, see channel-set.
Example
Bundle the timeslots 1, 2, and 8-12 of the CT1/PRI interface into a pri-set.

Any view
Parameter
serial serial-number: Interface type and number. If no interface is specified, the
information of all the E1-F interfaces will be displayed.
Description
Using the display fe1 serial command, you can view the configuration and state of
E1-F interface.
If the specified interface is a serial interface rather than an E1-F interface, the
system will display the error prompt “The serial is not a factional interface”.
Example
Display the information of the E1-F interface.
