Automatic IP address allocation
Determines whether the Sonar Head can be assigned an IP address from a DHCP
Server. By default, the Sonar Head uses a static IP address. You cannot change this
parameter — it is read only.
VDSL Profile
The VDSL2 standard defines various profiles that can optimize the data rate and link
performance on cables of different quality and lengths. For longer cables, you may
wish to use a profile with a lower bandwidth, such as profile 0 (8b) or 1 (12a).
The following profiles are available:
•
0 (8b)
: Suitable for long or low-quality cables, but has a slower data rate.
•
1 (12a)
: A good compromise for medium-length cables, or cables that are of
marginal quality, and provides a medium-speed data rate.
•
2 (30a)
: Suitable for short cables. Provides a fast data rate.
•
3 (30a)
: Provides the fastest data rate but is only suitable for very short cables.
Note
The maximum achievable data rate depends on a number of factors, such as cable
length, the number of junctions, and your slip ring installation. You can measure the
link speed by performing the “Testing the Sonar Head telemetry” procedure.
VDSL SNR Margin
The VDSL Signal to Noise Ratio (SNR) Margin controls the amount of noise and
tolerance in the cable. It is the difference between the actual SNR and the minimal
SNR required to sync at a specific speed. For longer cables, use 6 dB instead of 9 dB.
IP Address, Port, Subnet Mask, and Default Gateway
These network parameters are used to identify and locate the Sonar Head on the local
network. If you need to set up a unique network environment, you can change the IP
Address, Port, Subnet Mask, and Default Gateway of the Sonar Head using the
Head
Network Setup
dialog box.
Note
Your Sonar Processor must be on the same network as the Sonar Head.
