pri-set
Command Reference Guide
If a serial interface formed by bundling timeslots of the CT1/PRI interface is
encapsulated with PPP and is set to perform loopback, it is normal for the state
of the link layer protocol to be reported as DOWN.
Example
Set the interface E1 3/0/0 to perform local loopback.
[NEC-PHILIPS-E1 3/0/0]loopback local
Syntax
pri-set timeslot-list [ range ]
undo pri-set
View
CE1/PRI interface view
Parameter
range: The number of the timeslots that are bundled, which is in the range of 1
to 31. When specifying the timeslots to be bundled, you can specify a single
timeslot by specifying a number, a range of timeslots by specifying a range
between number1-number2, or several discrete timeslots by specifying
number1, number2-number3.
Description
Using the pri-set command, you can bundle the timeslots of a CE1/PRI
interface into a pri-set. Using the undo pri-set command, you can remove the
timeslot bundle.
By default, no timeslots are bundled into pri-set.
When perform pri-set bundling on a CE1/PRI interface, you should note that
you are not allowed to bundle only timeslot 16, as it will be used as the D
channel for transmitting signals. Attempts to bundle only timeslot 16 will fail.
In a pri-set formed by bundling the timeslots of 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 timeslots
are specified for bundling, all the timeslots except for timeslot 0 will be bundled
into an interface similar to an ISDN PRI interface in the form of 30B+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 of ISDN PRI interface. The serial interface is numbered in the form of
serial number:15. Where, number is 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 CE1/PRI interface into a pri-set.
[NEC-PHILIPS-E1 3/0/0]pri-set timeslot-list 1,2,8-12
