Network Setup for HDI 3000

Copying most of this straight from the user manual:

NetLink
NetLink is the network transfer of image information. NetLink conforms to the Digital Imaging and  Communications in Medicine (DICOM) standard, version 3.0. Centralized printers, print servers, network file servers, and review workstations that comply with these DICOM standards can take advantage of NetLink.
NetLink is a system option.With NetLink, you can store ultrasound images on theDICOM-compatible file server or archive device and review them using a workstation. You can also print exams directly. The NetLink setups are shown in Figure 9-4. The Directory of Image Management Setup Options is available from the Directory of Setup Options.

System Administrator Information
The system administrator is responsible for providing:

• A list of all equipment that is part of the Image Management network
  

• Logical diagram of the network showing topology, subnets, etc.
  

• Diagram of the network

• 
  Locations of equipment
  

• Locations of all LAN attachment points
  

• Locations of power outlets and connector types
  

• Locations of any dedicated analog phone lines
  

• All necessary Internet Protocol (IP) addresses and subnet information.

Configuration Files

The configuration files comprise the host table, device table, and the device files (Figure 9--5
through Figure 9--7). The primary vehicle for the configuration is the host table. The device table
and the device files contain information that supports the host table. The device table cannot be
edited. The host table and the device files can be edited. ATL suggests that the device files not be edited.

Syntax
The syntax for the host table entries is critical.

• Each line must end in a semicolon.
  

• At least one space must separate fields.
  

• Model ID is found in the device table and must be entered identically into the host table.
  

• The Alias cannot exceed 19 alphanumeric characters.
  

• The Title cannot exceed 64 alphanumeric characters.
  

• // are used to “comment out” text. When // precede a line of text, that text is ignored by the
  system relative to the configuration files. Comments are useful for system administration.

IP Address
Internet Protocol (IP) address consists of four fields of up to three digits separated by periods
(xxx.xxx.xxx.xxx). The value assigned to each field must be within the range of 0 to 255. An IP
address is required for each device on the network. Unused or spare network connection points
also require an IP address. The system administrator provides the IP address.

Subnet Name
Each subnet requires a subnet name. Subnet names are arbitrary identifiers (Subnet1, VxLAN, etc.). The subnet name occurs several times in the host table, and the name must have the same capitalization in each occurrence. The system administrator provides the subnet name.

Subnet Mask
There is a subnet mask for each subnet. Subnet masks use the same format as IP addresses: for example, 255.255.255.xxx (where xxx is a sequential number starting with 01 and incremented by 1 for each additional subnet). The purpose of the mask is to “mask off” the IP addresses and distinguish between a subnet and an individual network node. The system administrator provides the subnet mask.

Alias
Each device on the network requires an alias. The alias is an arbitrary name that describes the device. The aliases for the ultrasound system and the archive devices appear in the Image Management System Configuration setups as the Network ID. The aliases for the printers appear in the Printer setups. The system administrator provides the alias.

Port
The port for each device is found in the vendor’s DICOMConformance Specification. ATL uses 104.

Title
DICOM title, or just Title in the host table, is a unique name assigned to a device for purposes of DICOM communication. The system administrator assigns titles to devices.

Model ID
The Model ID is found in the device table. The Model ID serves as a connection to the device file. The Model ID found in the device table and the Model ID entered into the host table must be identical. Some of the information in the device file appears in the System setups. The System setups provide the avenue by which you change these device attributes. You can change the device file, but ATL recommends that you do not change it.
