Table 25 SHDSL

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.
