l If "Atm1/0/0 current state : Administratively DOWN" is displayed, ATM1/0/0 has been
shut down. Run the undo shutdown command on ATM1/0/0 to enable it.
l If "Atm1/0/0 current state : DOWN" is displayed, check the following items.
Item Expected Result Follow-up Operation
Check the
connection
between the local
and remote
interfaces.
The local and remote interfaces
are properly connected using a
cable.
If the local and remote
interfaces are not properly
connected, reconnect them. If
the fault persists, change the
cable between the two
interfaces.
Run the display
dsl interface
command in the
system view to
check the binding
mode of
G.SHDSL
interfaces, number
of the main
interface, and
number of bound
interfaces.
The value of the Port bind
status field indicates the
interface binding status:
l Normal: indicates that the
G.SHDSL interface is not
bound.
l MPair-X: indicates M-Pair
binding. X specifies the
number of bound interfaces.
l EFM-X: indicates EFM
binding. X specifies the
number of bound interfaces.
The Bind group master port
field indicates the main
interface. The requirements are
as follows:
l The local and remote
G.SHDSL interfaces use the
same binding mode.
l The numbers of bound
interfaces on both ends are
the same.
l The main interfaces on both
ends are the same.
If the binding modes of the
G.SHDSL interfaces, main
interfaces, or numbers of bound
interfaces on both ends are
different, perform the following
operations:
1. Run the following
commands on the four
G.SHDSL interfaces:
l Run the shutdown
command to shut down
the interfaces.
l Run the undo shdsl
bind command to delete
the binding
configurations from the
interfaces.
2. Run the set workmode slot
slot-id shdsl { atm | ptm }
command in the system view
to change the local binding
mode to be the same as the
remote binding mode.
3. Find the local main interface
according to the remote
main interface. Run the
shdsl bind command on the
local main interface to
change the local bound
interface quantity to be the
same as the remote bound
interface quantity.
If "Atm1/0/0 current state : DOWN" is still displayed, go to step 5.
l If "Atm1/0/0 current state : UP" is displayed, ATM1/0/0 is in the Up state. Go to step 2.
Step 2 Check that the local and remote G.SHDSL interfaces use the same transmission standard.
