R3303-HP HSR6800 Routers Interface Configuration Guide

41
When the E1 line is working in framed (CE1) mode, you can bundle timeslots on it. The system
automatically creates a serial interface named serial number/line-number:set-number for it. This
interface operates at N × 64 kbps and is logically equivalent to a synchronous serial interface where you
can make other configurations.
CE3 interfaces support link layer protocols PPP, HDLC, and FR and network protocol IP.
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. Configure the interface to
operate in E3 mode.
using e3
The default operating mode is CE3
mode.
4. Configure the interface to
operate in FE3 mode and set
the DSU mode or the subrate.
fe3 { dsu-mode { 0 | 1 } | subrate
number }
Optional.
By default, DSU mode 1 (the
Kentrox mode) is adopted, and the
subrate is 34010 kbps.
5. Set other interface
parameters.
See "Configuring other CE3
interface parameters."
Optional.
Configure PPP, FR, and IP address for the CE3 interface if the network requires.

using ce3
Optional.
The default operating mode is CE3
mode.
4. Set the operating mode of an
E1 line on the CE3 interface to
unframed mode or framed
mode.
• Set the operating mode to
unframed (E1) mode:
e1 line-number unframed
• Set the operating mode to
framed (CE1) mode and
bundle timeslots on the CE1
interface:
a. (Optional) undo e1
line-number unframed
b. e1 line-number
channel-set set-number
timeslot-list list
By default, E1 lines are operating
in framed mode, but no channel
sets exist.
