Views
ATM (G.SHDSL) interface view
Default command level
2: System level
Parameters
16: Specifies the interface to use 16-Pulse Amplitude Modulation (16-PAM) constellation, where the rate
range is 192 to 3840 kbps.
32: Specifies the interface to use 32-PAM constellation, where the rate range is 768 to 5696 in kbps.
auto: Specifies the interface to select its PAM automatically.
Usage guidelines
On G.SHDSL interfaces, the 16 and auto keywords are available, and the auto keyword applies by
default.
On G.SHDSL.bis interfaces, the 16, 32, and auto keywords are available, and the auto keyword applies
by default.
When both the shdsl mode cpe command and the shdsl capability auto command are configured, if the
current interface is a G.SHDSL.bis interface, the shdsl pam 32 command can be configured on the
interface. If the current interface is a G.SHDSL interface, the configured shdsl pam 32 command does not
take effect.
