Utilizing a Virtual Private Network provides better security by blocking
external TCP/UDP ports, such as RDP 3389, which would need to be forwarded for
remote access capability. |
 |
The use of the
Sybase Advantage DataBase (SQL)
Server is mandatory for all clients utilizing Remote Desktop and/or
wireless. |
 |
Recommended bandwidth per user:
30 kbps (note: up to 50/70 kbps
may be required if the TWAINWAN solution is implemented)
The number of users will decrease based on the number remote users
and the size of the data and also the transfer of pictures/documents to the main
location. As for redundancy, generally every office is different. Most offices
are not able to obtain a redundant connection due to logistics and costs. A
dialup Remote Access Service will provide minimal access to the patient data at
the main location. Any other alternate redundant connectivity over and above
that is the client’s
prerogative.

The general
memory recommendation for servers running terminal services is a minimum of
50MB of memory per session. This requirement does not include any other
application or the operating system’s general memory requirements.
|
 |
All sessions
require a unique USER environmental variable for CBS and CBSWAN variables
(where applicable). |
 |
Windows XP Professional and Vista Business have Terminal Server capabilities and can be used in
certain environments. The local user
will not be able to use the station while a remote connection is active.
|
 |
Remote Access can also be set up by using a DNS service and forwarding the
RDP port (generally TCP 3389) to any local computer with RDP capability. There are limitations to this type of connection.
One local workstation is tied up
as long as the remote user is in a session and connected. A third-party
software, such as
Elusiva*, can also be used to access Advantage software remotely.

 |
Some
USB printers are not compatible with Remote/Terminal Server printing.
Upgrading to Microsoft's latest
RDP client
is highly recommended for clients with remote printing issues. (this
web site contains many articles regarding terminal server printing. Use
the search tool to locate these documents) |
 |
For Security enhancements a VPN can be implemented. VPN
creates a Point to Point tunneling which utilizes encrypted transmission between the two sites and is
strongly recommended
by Compulink and will make the wide area network
HIPPA compliant. A VPN is required
for transferring TWAIN images to
the main site (See TWAINWAN setup).
|
Please Note:
In order to utilize Advantage TWAIN compliant peripherals
such as Insurance Card
Scanners, Patient's Face Capture, Document Scanners and some Barcode printing
over Terminal services in a Wide Area Network, a VPN (Virtual
Private Network) is required.
*Compulink
has successfully tested Elusiva with Advantage software but cannot guarantee it's compatibility or
functionality. Clients are responsible for setup and maintenance of
any type of remote connection.
