Chapter 2 — Networking, Security, and Support Connectivity TriTech recommends for each Inform CAD dispatch workstation an individual account be used to allow the Dispatcher or Call Taker to log in their workstation. Alternatively, each Dispatcher or Call Taker is assigned his or her own individual user account to log into the workstation. The customer's Inform CAD users need a defined level of security access at the workstation level in order for Inform CAD to successfully operate. This is generally setup via Power User security access. The following levels of access are required for an Inform CAD user: / User must have 'Modify' permissions to the local hard drive (Read & Execute, List Folder Contents, Read, and Write). / User must be able to write to the registry 1 User must be able to register COM components / User must be able to create desktop icon(s) / User must be able to communicate on TCP ports / User must be able to ability to set the system time / User must be able to map and access the Q: drive / User must be able to make ODBC and OLE/DB connections to the SQL Server(s) / User must be able to write messages to Microsoft message Queue (MSMQ) 3.2.6 INFORM MOBILE WORKSTATIONS The customer's Inform Mobile users need a Windows account that allows the application to synchronize device time with a compatible GPS time sync signal in Inform CAD 5.7. Since time stamps for actions such as status changes are performed based upon the device time, failed time synchronization will cause unexpected results. 3.3 INFORM CAD OPERATION VIA WIDE AREA NETWORK WAN bandwidth requirements for Inform CAD workstations to run remotely will vary based upon the overall size of the system and the utilization level for interfaces and features. VPN is not recommended for connecting a workstation via a WAN. This is due to orphaned connections of Microsoft components that can cause the failure of system components. Please consult with TriTech before activating one or more remote workstations. TriTech recommends the use of Citrix or ClearCube for running Inform CAD workstations across a WAN connection that is less than 100Mbps to the desktop or where the connection must be established via VPN. The use of Citrix with Inform CAD is described later in this document in Section 12. TriTech works with the customer to establish an effective deployment plan for machine names. The following guidelines are recommended for machine names: The contents of this material are confidential and proprietary to TriTech Software Systems, Inc. and may not be reproduced, published or disclosed to others without the prior written consent of TriTech Software Systems, Inc. ©2015 TriTech Software Systems
