Recommended bandwidth per user: 30 kbps
A
solid/stable DSL connection provides a minimum of 384 kbps and can reach up to
1.5 Mbps and will accommodate anywhere from 5 to 20 users considering the
overhead. 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 128 MB of RAM, plus an extra 25 MB of memory per client.
|
 |
A
WAN can also be set up by using a dialup modem and RAS utilizing Terminal
Services and PCAnywhere. This method is not recommended due to the speed
and bandwidth issues.
|
 |
PCAnywhere with Broadband connection is an acceptable method of running
Advantage Software. 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.

 |
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).

 |
Windows XP Professional has 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.

 |
The use of the
Sybase Advantage DataBase (SQL)
Server is mandatory for all WAN clients.
