Huawei V200R001C01 - 6.1 Voice Service Troubleshooting; 6.1.1 No Feed Is Detected on a Telephone

Run the display dsl interface command in the system view to check the transmission standard
of the G.SHDSL interfaces. The value of the Port transmission mode field indicates the
transmission standard.
l If the local and remote G.SHDSL interfaces use different transmission standards, run the
shdsl annex command on the local G.SHDSL interface to change its transmission standard
to be the same as the transmission standard of the remote G.SHDSL interface.
l If the local and remote G.SHDSL interfaces use the same transmission standard, go to step
3.
Step 3 Check that the local and remote G.SHDSL interfaces work in the same PSD mode.
Run the display dsl interface command in the system view to check the PSD mode of the
G.SHDSL interfaces. The value of the Port power spectral density field indicates the PSD
mode.
l If the local and remote G.SHDSL interfaces work in different PSD modes, run the shdsl
psd command in the G.SHDSL interface view to change its PSD mode to be the same as
the PSD mode of the remote G.SHDSL interface.
l If the local and remote G.SHDSL interfaces work in the same PSD mode, go to step 4.
Step 4 Check that ATM is correctly configured.
l If IP packets are transmitted over ATM links, check the following items.
Item Expected Result Follow-up Operation
Run the display
this command in
the G.SHDSL
interface view to
check whether the
IP address of the
local G.SHDSL
interface is on the
same network
segment as the IP
address of the
remote interface.
IP addresses of the local
G.SHDSL interface and the
remote interface are on the
same network segment.
If IP addresses of the local
G.SHDSL interface and the remote
interface are on different network
segments, run the ip address
command in the G.SHDSL
interface view to assign the local
G.SHDSL interface an IP address
that is on the same network
segment as the IP address of the
remote interface.
Run the display
this command in
the ATM-PVC
view to check
whether IPoA
mapping is
correctly
configured on the
PVC.
The mapped IP address is the
IP address of the remote
interface.
If the mapped IP address is not the
IP address of the remote interface,
run the map ip command in the
ATM-PVC view to configure the IP
address of the remote interface as
the mapped IP address.
l If IPoE packets are transmitted over ATM links, check the following items.
