The maximum distances for VDSL links using the recommended profiles are:

 

 

 

 

 

 

Upstream

Downstream

Mode

Max. Range

 

 

 

 

 

 

16 Mbps

16 Mbps

Symmetric

600m (1970 ft)

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.

Example

Console#config

 

Console(config)#efm profile global S1-16-16
