SHDSL
You can setup the SHDSL parameters by using the command shdsl . Move the cursor “ >> “ to
shdsl and press enter.
>> mode Configure SHDSL mode
n*64 Configure SHDSL data rate
type Configure SHDSL annex type
clear Clear current CRC error count
margin Configure SHDSL SNR margin
There are two types of SHDSL modes, STU-C and STU-R. STU-C means the terminal of central
office and STU-R customer premises equipment.
You can setup the data rate in multiples of 64Kbps where n is from 0 to 32. If you configure n as
0, the SHDTU03 will perform in adaptive mode.
There are two types of SHDSL Annex types, Annex-A and Annex-B.
Clear command can clear the CRC error count.
Generally, you do not need to change the SNR margin, whose range is from 0 to 10. The SNR
margin is an index of line connection. You can see the actual SNR margin in STATUS SHDSL.
The larger the SNR margin, the better the line connection. If you set SNR margin in the field as 2,
the SHDSL connection will drop and reconnect when the SNR margin is lower than 2. On the
other hand, the device will reduce the line rate and reconnect for better line connection.
