Figure 4-5 Vdsl Status Example - ZyXEL Communications P841C User Manual

P841C Central-Side VDSL Modem
This command makes the P841C loads new VDSL modem code into the P841C (LT) or P841 (NT). If "LT" is
specified, the P841C will load the VDSL modem code into the P841C. If "NT" is specified, the P841C will load
the VDSL modem code into the P841. The VDSL connection should automatically reconnect after the new VDSL
modem code has been successfully loaded.
4.1.6 VDSL Reset Command
This command causes a software reset to the VDSL Chip (local or remote). The VDSL link first disconnects
before the channel resets.
4.1.7 VDSL Reconnect Command
This command forcibly causes the P841C to reconnect the VDSL link.
4.1.8 VDSL Status Command
This command shows the VDSL status register values as shown in the next example. Information in these fields is
mainly for debugging purposes.
SNR, MSE and RS_ERR are polled every three seconds. Total RS_ERR are counted during the connection. SNR,
MSE, RS_ERR and Total_RSERR are cleared after the VDSL is link up.
