R3303-HP HSR6800 Routers Interface Command Reference

Usage guidelines
A CE1 interface in CE1 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 interface, and set-number is the number of the channel set.
A CE1 interface supports only one timeslot bundling mode at a time.
IMPORTANT:
Make sure the local end has the same timeslot bundling settings as the remote end for successful
communication.
Examples
# Bundle timeslots 1, 2, 5, 10 through 15, and 18 on CE1 interface E1 2/0/0 into channel set 0.
<Sysname> system-view
[Sysname] controller e1 2/0/0
[Sysname-E1 2/0/0] channel-set 0 timeslot-list 1,2,5,10-15,18
# Perform the same configuration on CE1 interface E1 2/0/0 of the peer router.
<Sysname> system-view
[Sysname] controller e1 2/0/0
[Sysname-E1 2/0/0] channel-set 0 timeslot-list 1,2,5,10-15,18
clock (CE1 interface)
Use clock to configure clock source for the CE1 interface.
Use undo clock to restore the default.
Syntax
clock { master | slave }
undo clock
Default
The clock source is line clock (slave).
