4. The maximum distances for VDSL links using the recommended profiles are:
5. Type-1 26 AWG (100 ohm)/0.4 mm, or Type-2 24 AWG (100 ohm)/0.5 mm
cable may be installed to achieve the maximum distance. However, typically,
24 AWG (100 ohm)/0.5 mm wire is better than 26 AWG (100 ohm)/0.4 mm
wire. Note that the distance may be limited by factors such as how the cable
is bundled, and the interference and noise on the link.
6. Public profiles conform to specific standards such as ANSI or ETSI. Private
profiles do not conform to these standards.
Command Attributes
• Profile Name – The name for the specific set of communication parameters.
• Profile Type – Public profiles are those that meet specific standards e.g., ETSI
or ANSI. Private profiles do not meet these standards. The ports on a VDSL
switch can be assigned the same or different profiles.
• Downstream Rate
–
Rate of data transmission from the switch to the CPE.
• Upstream Rate – Rate of data transmission from the CPE to the switch.
Web – Click VDSL, Global Configuration, and select a profile from the drop-down
list.
CLI – This example shows how to configure all VDSL ports on the switch to profile
S1-16-16.
