Configuration procedure
To configure an ATM E3/T3 interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter ATM E3/T3 interface
view.
interface atm interface-number N/A
3. Set the clock mode.
clock { master | slave }
Optional.
The default setting is slave.
4. Set the framing format.
• On an ATM E3 interface:
frame-format { g751-adm |
g751-plcp | g832-adm }
• On an ATM T3 interface:
frame-format { cbit-adm |
cbit-plcp | m23-adm |
m23-plcp }
Optional.
The framing format for an ATM E3
interface is G.751 PLCP and for an
ATM T3 interface is C-bit PLCP.
5. Set the cable mode.
cable { long | short }
Optional.
The default setting is short haul.
6. Enable scrambling.
scramble
Optional.
Scrambling is enabled by default.
7. Set the loopback mode.
loopback { cell | local | payload |
remote }
Optional.
Loopback is disabled by default.
8. Set the intended bandwidth
for the ATM E3/T3 interface.
bandwidth bandwidth-value Optional.
9. Restore the default settings for
the ATM E3/T3 interface.
default Optional.
NOTE:
E3 configurations are supported on the ATM (E3) interface module and T3 configurations on the ATM (T3)
interface module.
