VDSL Commands

2.

A suffix of “A” in the profile name (e.g., S2-16-16A) indicates that this

 

 

profile is for both VDSL and ADSL lines in a bundle. Profiles without a

 

 

suffix of “A” in the profile name (e.g., S1-16-16) are for VDSL lines only.

3.

The following profiles are recommended for use with this switch: S1-16-16,

 

 

S2-16-16A, A1-34-11, and- A2-34-11A.

 

4.

The maximum distances for VDSL links using the recommended profiles

 

 

are:

 

 

 

 

 

 

 

 

 

 

 

Upstream

Downstream

Max. Range

 

 

 

 

 

 

 

 

16 Mbps

16 Mbps

Symmetric

600m (1970 ft)

 

 

 

 

 

 

 

 

11 Mbps

34 Mbps

Asymetric

610m (2000 ft)

 

 

 

 

 

 

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.
