Configuring the ADSL Line Interfaces
Checking the status of an ADSL-DMT interface
admin> set line-config rate-adapt-mode-up = automatic-at-startup
admin> set line-config rate-adapt-mode-down = automatic-at-startup
admin> set line-config line-latency-up = interleave
admin> set line-config line-latency-down = interleave
admin> set interleave-path-config min-bitrate-up = 56
admin> set interleave-path-config max-bitrate-up = 256
admin> set interleave-path-config min-bitrate-down = 512
admin> set interleave-path-config max-bitrate-up = 1500
admin> write
AL-DMT/{ shelf-1 slot-1 4 } written
The following commands reserve virtual path identifier (VPI) 7 for virtual path (VP)
switching on the interface:
admin> read al-dmt { 1 1 4 }
AL-DMT/{ shelf-1 slot-1 4 } read
admin> set line-config vp-switching-vpi = 7
admin> write
AL-DMT/{ shelf-1 slot-1 4 } written
Checking the status of an ADSL-DMT interface
The system creates a read-only AL-DMT-Stat profile for each ADSL-DMT interface.
The profiles provide statistics and connection status. Following are the relevant
parameters, shown with sample settings for an active line:
[in AL-DMT-STAT/{ shelf-1 slot-1 4 }]
physical-address* = { shelf-1 slot-1 4 }
line-state = active
vpi-vci-range = vpi-0-15-vci-32-127
vp-switching-vpi = 15
physical-status = { 0 coe down 0 0 0 0 none none 0000 4 0 14 init-ok +
physical-statistic = { { 0 0 0 } no 0 passed 0 0 0 0 0 0 0 0 0 0 0 0 0 +
Parameter
line-state

vp-switching-vpi
7-14
Setting
Indicates the overall state of the line. Possible values are as
follows:
does-not-exist—Link is not physically present on board.
disabled—Line is disabled.
active—Multipoint is established.
Indicates the valid range of VPI and virtual channel identifier
(VCI) for the circuits established for the line. This range can
change only after reboot.
Indicates the VPI to be used for the VP switching. The rest of
the VPIs are used for the virtual circuit (VC) switching.
