Ima; Configuring An Atm E1/T1 Interface - HP HSR6800 Configuration Manual

IMA

This section describes physical parameter configuration of ATM E1/T1 interfaces. For more information
(including the configuration of PVCs), see Layer 2—WAN Configuration Guide.

Configuring an ATM E1/T1 interface

Step
1. Enter system view.
2. Enter ATM E1/T1 interface
view.
3. Set the clock mode.
4. Enable automatic clock
mode change.
5. Set the framing format.
6. Set the line coding format.
7. Enable scrambling.
8. Set the cable mode.
9. Set the intended bandwidth
for the ATM E1/T1 interface.
10. Set the loopback mode.
11. Restore the default settings for
the ATM E1/T1 interface.
NOTE:
E1 configurations are supported on the IMA (E1) interface module and T1 configurations on the IMA (T1)
interface module.

Optional.
The default setting is slave.
Optional.
This function is disabled by default.
Optional.
By default, the framing format for
an E1 interface is CRC4 ADM and
that for an T1 interface is ESF
ADM.
Optional.
The default line coding format for
an E1 interface is HDB3 and for a
T1 interface is B8ZS.
Optional.
Scrambling is enabled by default.
Optional.
The default cable mode is long. In
this mode, the system
automatically adapts the cable
mode to the cable actually
connected.

Optional.
Loopback is disabled by default.
