Configuring an ATM OC-3c/STM-1 interface

ATM OC-3c/STM- 1 is the physical transmission medium for ATM interfaces. Its transmission rate is 155
Mbps. This section covers only the physical configurations of the ATM OC-3c/STM- 1 interfaces. For
information about configuring ATM services, see Layer 2—WAN Configuration Guide.
To configure an ATM OC-3c/STM- 1 interface:
Step
1. Enter system view.
2. Enter ATM
OC-3c/STM- 1 interface
view.
3. (Optional.) Configure
the interface
description.
4. Configure the clock
mode for the interface.
5. Configure the frame
format for the interface.
6. (Optional.) Enable
payload scrambling on
the interface.
7. Configure overhead
bytes for the interface.
8. (Optional.) Enable
loopback detection on
the interface and set the
detection mode.

N/A
By default, the description is
interface-name Interface, such as ATM
2/4/0 Interface.
By default, the clock mode is slave.
By default, the frame format is SDH.
By default, payload scrambling is
enabled.
The default value for c2 is 0x13.
By default, the system adopts the SDH
frame format.
The default values for both j0 and j1 are
null.
By default, loopback detection is disabled.
