Command Reference
pri-set (CT1/PRI Interface)
Purpose Use the pri-set command to bundle the timeslots of the CT1/PRI interface into a
pri-set.
Use the undo pri-set command to remove the timeslot bundle.
Syntax pri-set [ timeslot-list range ]
undo pri-set
Parameters range
The number of the timeslots that are bundled. Valid
values are 1 to 24. When specifying the timeslots to be
bundled, you can specify one timeslot by specifying its
number, a timeslot range by specifying a range in the
form number1-number2, or several discrete timeslots
by specifying number1, number2-number3.
Default By default, no timeslots are bundled into pri-sets.
Example Bundle the timeslots 1, 2, and 8 through 12 of the CT1/PRI interface into a pri-set.
[3Com -T1 1/0/0] pri-set timeslot-list 1,2,8-12

Description When creating a pri-set on a CT1/PRI interface, note that timeslot 24 is D channel for
transmitting signaling; it cannot form a bundle that includes itself only. The attempts
to bundle only timeslot 24 will fail.
In a pri-set formed by timeslot bundling on a CT1/PRI interface, timeslot 24 is used as
D channel for signaling transmission, and other timeslots as B channels for data
transmission. You may randomly bundle these timeslots into a pri-set (as the D
channel, timeslot 24 is automatically bundled). The logic features of this pri-set will be
the same like those of an ISDN PRI interface. If no timeslot is specified, all timeslots
are bundled into an interface similar to an ISDN PRI interface in the form of 23B+D.
The system automatically creates a serial interface after timeslot bundling on the
interface. This serial interface has the same logic features of ISDN PRI interface. The
serial interface is numbered in the form of serial
number:23, where number is the
number of the CT1/PRI interface where the serial interface is created.
Only one timeslot bundling mode is supported on a CT1/PRI interface at a time. In
other words, you cannot use this command and the
channel-set command
together.
