framing signal transmission and does not support bundling. All other timeslots can be randomly
bundled into n × 64 kbps channels, where n is the number of bundled timeslots.
A CE3 interface can be channelized into E1 lines in framed mode or unframed mode.
{ When an E1 line is operating in unframed (E1) mode, the system automatically creates a
2048-kbps synchronous serial interface numbered serial number/line-number:0 for it.
{ When the E1 line is operating in framed (CE1) mode, you can bundle timeslots on it. For each
channel set, the system automatically creates a synchronous serial interface numbered serial
number/line-number:set-number. The interface rate is n × 64 kbps, where n is the number of
bundled timeslots.
• The synchronous serial interface created in either mode has the same logical features as a standard
synchronous serial interface. You can configure this interface in the same way you configure a
standard synchronous serial interface.
Configuring a CE3 interface in E3 mode
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter CE3 interface view.
controller e3 interface-number N/A
3. (Optional.) Configure the
interface to operate in E3
mode.
using e3
The default operating mode is CE3
mode.
4. (Optional.) Configure the
interface to operate in FE3
mode and set the DSU mode or
the subrate.
fe3 { dsu-mode { 0 | 1 } | subrate
number }
By default, DSU mode 1 (the
Kentrox mode) is adopted, and the
subrate is 34010 kbps.
5. (Optional.) Configure the
interface description.
description text
By default, the description of an
interface is interface-name
Interface.
6. (Optional.) Configure the CE3
interface to perform BERT test.
bert pattern { 2^7 | 2^11 | 2^15
| qrss } time number [ unframed ]
By default, no BERT test is
performed.
7. (Optional.) Set the clock mode.
clock { master | slave }
The default mode for both the CE3
interface and E1 line is slave,
which is line clock.
8. (Optional.) Set the national bit.
national-bit { 0 | 1 } The default is 1.
9. (Optional.) Enable loopback.
loopback { local | payload |
remote }
By default, loopback is disabled.
10. (Optional.) Restore the default
settings for the CE3 interface.
default N/A
11. (Optional.) Bring up the CE3
interface.
undo shutdown By default, a CE3 interface is up.
12. Return to system view.
quit N/A
13. Enter synchronous serial
interface view of an interface
formed by a CE3 interfaces.
