Chapter 4 - Advanced Setup
Advanced ADSL
ADSL modulation is congured in the Advanced ADSL menu. The default setting automatically detects the appropriate modulation for the connection, therefore it
should not be necessary to change this setting for the Router to function.
Modulation types supported by the Router include: ADSL2, ADSL2+, G.DMT T1.143
and G.lite. If the Modulation Mode is changed from the default Auto Synch-Up, the
mode used must be supported by the ISP in order for the ADSL signal to function.
Likewise for changing the ANNEX type, if the Type used is not supported by the
ISP in your region, the ADSL signal will not function.
The Bitswap and SRA (Seamless Rate Adaptation) features can be enabled here.
If your ADSL modulation is ADSL2 or ADSL2+, these features will only be useful if
supported by the ISP. If you opt to use either of these, some experimentation might
be advisable to test ADSL synchronization and signal performance for improvement
or degradation.
