202 CHAPTER 12: FUNDAMENTAL CE1/PRI INTERFACE CONFIGURATION COMMANDS
Description Use the channel-set command to bundle timeslots on the CE1/PRI interface into
a channel-set.
Use the
undo channel-set command to restore the default.
By default, no timeslots are bundled into channel sets.
A CE1/PRI interface in CE1/PRI mode is physically divided into 32 timeslots
numbered 0 through 31.
In actual applications, all the timeslots except timeslot 0 can be bundled into
multiple channel sets. For each channel set, the system automatically creates a
serial interface which is logically equivalent to a synchronous serial interface.
The serial interface is numbered in the form of serial
interface-number:set-number, where, interface-number is the number of the
CE1/PRI interface, and set-number is the number of the channel set.
Only one timeslot bundling mode can be supported on a CE1/PRI interface at a
time. In other words, this command cannot be used together with the pri-set
command.
Example # Bundle timeslots 1, 2, 5, 10 through 15, and 18 on CE1/PRI interface E1 2/0 into
channel set 0.
<Sysname> system-view
[Sysname] controller e1 2/0
[Sysname-E1 2/0] channel-set 0 timeslot-list 1,2,5,10-15,18
# Make the same configuration on the CE1/PRI interface on the remote router.
<Sysname> system-view
[Sysname] controller e1 2/0
[Sysname-E1 2/0] channel-set 0 timeslot-list 1,2,5,10-15,18
clock (CE1/PRI interface view)
Syntax clock { master | slave }
undo clock
View CE1/PRI interface view
Parameter master: Adopts the internal clock as the clock source.
slave: Adopts the line clock as the clock source.
Description Use the
clock command to configure clock source for the CE1/PRI interface.
Use the
undo clock command to restore the default clock source, that is, line
clock.
