Command Remarks
1. Enter system view.
system-view N/A
2. Enter ATM E1/T1 interface
view.
interface atm interface-number N/A
3. Set the clock mode.
clock { master | slave }
Optional.
The default setting is slave.
4. Enable automatic clock mode
change.
clock-change auto
Optional.
This function is disabled by
default.
5. Set the framing format.
• On an E1 interface:
frame-format { crc4-adm |
no-crc4-adm }
• On a T1 interface:
frame-format { esf-adm |
sf-adm }
Optional.
By default, the framing format for
an E1 interface is CRC4 ADM
and that for an T1 interface is
ESF ADM.
6. Set the line coding format.
• On an E1 interface:
code { ami | hdb3 }
• On a T1 interface:
code { ami | b8zs }
Optional.
The default line coding format for
an E1 interface is HDB3 and for
a T1 interface is B8ZS.
7. Enable scrambling.
scramble
Optional.
Scrambling is enabled by
default.
8. Set the cable mode.
cable { long | short }
Optional.
The default cable mode is long.
In this mode, the system
automatically adapts the cable
mode to the cable actually
connected.
9. Set the intended bandwidth
for the ATM E1/T1 interface.
bandwidth bandwidth-value Optional.
10. Set the loopback mode.
loopback { cell | local | payload |
remote }
Optional.
Loopback is disabled by default.
11. Restore the default settings for
the ATM E1/T1 interface.
