R2511-HP MSR Router Series Interface Command Reference(V5)

<Sysname> system-view
[Sysname] interface atm 1/0
[Sysname-Atm1/0] shdsl psd asymmetry
shdsl rate
Use shdsl rate to set the single-pair interface rate of the SHDSL interface.
Use undo shdsl rate to restore the default.
Syntax
shdsl rate { auto | rate }
undo shdsl rate
Default
Auto applies.
Default
The rate of two-wire G.SHDSL interface is set to auto-negotiation mode; the single-pair interface rate of
four-wire G.SHDSL interface is set to 2,312 kbps (four-wire G.SHDSL interface rate is 4,624 kbps); the rate
of two-wire and four-wire G.SHDSL.bis interfaces is set to auto-negotiation mode.
Views
ATM (G.SHDSL) interface view
Default command level
2: System level
Parameters
auto: Auto-negotiation mode.
rate: Maximum single-pair rate of the G.SHDSL interface, in the range of 64 to 2,312, in units of kbps.
Usage guidelines
For four-wire (dual-pair) G.SHDSL, the interface rate is two times single-pair rate. For example, if you set
single-pair rate to 2,312 kbps, four-wire interface rate is 4,624 kbps.
Because four-wire G.SHDSL interfaces cannot negotiate rate, do not set their single-pair interface rate to
auto mode.
The value range for the single-pair interface rate of the G.SHDSL.bis interface is 192 to 5696 kbps.
In actual applications, the maximum downlink rate is not likely to reach the specified rate as restricted by
ATU-C and line conditions. If you select the auto mode, CPE and CO can negotiate a rate commensurate
with the current line condition during the activation process. If fixed rates are set at both ends, the two
parties negotiate a rate. In case the lower rate between them cannot be provided, the line cannot be
activated.
