Displaying And Maintaining Ce1 Interfaces; Configuring An E1-F Interface - H3C SR6600 Configuration Manual

Step
7. Set the clock mode.
8. Enable automatic clock
mode change.
9. Set the line idle code type.
10. Set the type and the number
of interframe filling tags.
11. Set the loopback mode.
12. (Optional.) Restore the
default settings for the CE1
interface.
13. Bring up the CE1 interface.
14. Return to system view.
15. Enter the view of the
synchronous serial interface.
16. Set the CRC mode.

Displaying and maintaining CE1 interfaces

Execute display commands in any view and reset commands in user view.
Task
Display information about CE1 interfaces.
Display information about a channel set.
Clear statistics for CE1 interfaces.

Configuring an E1-F interface

E1-F interfaces, which are fractional E1 interfaces, are simplified CE1 interfaces. They are a
cost-effective alternative to CE1 interfaces for E1 access services that do not require multiple
channel sets.
An E1-F interface has the following features:
•
In framed mode, an E1-F interface can bind timeslots into only one channel set. In contrast, a
CE1 interface can group and bundle timeslots randomly into multiple channel sets.
•
An E1-F interface can operate in either framed (the default) or unframed mode.

Remarks
The default clock mode is slave,
which is line clock.
By default, automatic clock mode
change is disabled.
The default is 0x7E.
By default:
•
The type of the interframe
filling tag is 0x7E.
•
The number of interframe
filling tags is four.
By default, loopback is disabled.
N/A
By default, a CE1 interface is up.
N/A
mode:
serial
Make sure the synchronous serial
interface is the one created for
CE1 interface.
The default is 16-bit CRC.
