LABEL DESCRIPTION
4 Wire Connection Select Enable to activate 4-wire connection. The 4-wire mode is described in ITU-
T G.991.2. 4-wire mode can increase the reach of a particular data rate without
having to regenerate the signal. It can also give increased bandwidth for LAN-to-
LAN applications.
Otherwise, select Disable.
Mode Select CPE (Customer Premises Equipment) if the Prestige is connected to the
ISP. This is the default setting.
To connect the Prestige to another SHDSL router, select CO (Central Office) here
and set the remote SHDSL router to CPE mode. Or vise versa if you select CPE
on the Prestige.
Annex Type Select a DSL operating mode.
Annex_A (default) is mostly used in North America, whereas Annex_B is more
widespread in Europe.
Annex_A_B, Annex_A_B_ANFP (Access Network Frequency Plan) and
Annex_B_ANFP are automatically selected when the DSL line is in training state.
These options are not available in CO mode.
Note: For LAN-LAN connection, make sure the annex type is the
same on Prestige and the remote SHDSL router.
Bit Rate Mode Specify the bit rate. Choices are fixed or adaptive.
Fix Bit Rate This field is applicable when you select Fixed in the Bit Rate Mode field.
Select a fixed transfer rate for the DSL line from the drop-down list box.
Activate Line Select false to disable SHDSL connection.
Select true to enable SHDSL connection.
Note: After you change the SHDSL line settings here, you must
disable and enable the SHDSL line again to make the
changes take effect.
