Command Reference
pri-set
Purpose Use the pri-set command to bundle timeslots on the CT1/PRI or CE1/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
Number of bundled timeslots. Valid values are 1 to 31
in CE1/PRI interface view and from 1 to 24 in CT1/PRI
interface view. 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
in the form number1 number2-number3.
Default By default, no timeslots are bundled into pri-sets.
Example On the CE1/PRI interface bundle timeslots 1, 2, and 8 through 12 into a pri-set.
[3Com -E1 3/0/0] pri-set timeslot-list 1,2,8-12
View This command can be used in the following views:
■ CE1/PRI Interface view
■ CT1/PRI Interface view
Description When creating a pri-set on a CE1/PRI interface, note the following:
■ Timeslot 16 is D channel for transmitting signaling; it cannot form a bundle that
includes itself only. The attempt to bundle only timeslot 16 will fail.
■ In a pri-set formed by timeslot bundling on a CE1/PRI interface, timeslot 0 is used
for frame synchronization control (FSC), timeslot 16 as a D channel for signaling
transmission, and other timeslots as B channels for data transmission. You may
bundle the timeslots except for timeslot 0 into a pri-set (as the D channel, timeslot
16 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 except for
timeslot 0 are bundled into an interface similar to an ISDN PRI interface in the form
of 30B+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:15, where number
is maximum serial interface number plus 1.
