Issue What is the baud rate when you are direct connected to a NPR 2000 Environment I/NET site Cause What is the baud rate when you are direct connected to a NPR 2000? Resolution It is fixed at 19,200. (TCON 209, Serial Port Configuration)

Issue When configuring Hosts to communicate using TCP/IP may I use the same host address for each workstation? Environment I/NET site Cause When configuring Hosts to communicate using TCP/IP may I use the same host address for each workstation? Resolution No. This number MUST be unique. (TCON 209)

Issue What is File Equalization? Environment I/NET Site Cause What is File Equalization? Resolution File Equalization allows host workstations connected to an Ethernet LAN to share certain data files. (TCON 209, 1-10)

Issue If the Filemaster workstation is powered off, will file equalization still occur? Environment I/NET file equalization Cause The filemaster is required for equalization. Resolution If the filemaster workstation is powered off, or if EqualSrv is not  available, file equalization cannot occur. Furthermore, other host  workstations will not be able to modify any of the equalized files. It is recommended that the filemaster workstation be powered by a uninterruptable power supply (UPS). See TCON 209, 1-13 for more information.

Issue If the Filemaster workstation is "ON" but the Equalsrv is not available, will File Equalization still occur? Environment I/NET Site Cause If the Filemaster workstation is "ON" but the Equalsrv is not available, will File Equalization still occur? Resolution No, file equalization will not occur without Equalsrv. For more information, see TCON300.

Issue Does I/NET 2000 launch "EqualCli" automatically? Environment I/NET 2000 Cause File equalization is required if you have more than one host workstation which will need access to any of the above files. One host workstation is designated as the filemaster. This designation is performed in the Configure program and is maintained in the configuration profile. When you select the Set as filemaster option, Configure automatically completes the filemaster name field with the Computer name (found in the Identification tab under Windows Network settings). The filemaster name field is read-only on the filemaster station and cannot be changed. Resolution Yes, EqualCli will launch automatically. For more information see TCON 209, The Filemaster, 1-13. When the workstation is designated as the filemaster, I/NET stores a master copy of each equalized file in the \MSTR directory. It is important that the designated workstation be constantly powered and that the EqualSrv program be running. EqualSrv will dock an icon in the system tray to indicate it is active. Both EqualSrv and EqualCli are launched automatically by I/NET on the filemaster workstation and stay running as background tasks, even when I/NET is shut down. If necessary, you can manually shut down EqualSrv from the system tray icon menu. Warning: If the filemaster workstation is powered off, or if EqualSrv is not available, file equalization cannot occur. Furthermore, other host workstations will not be able to modify any of the equalized files. It is recommended that the filemaster workstation be powered by a uninterruptable power supply (UPS). All other host workstations must enter the Computer name of the filemaster workstation in the Filemaster name field. I/NET launches the EqualCli program on the host workstations automatically. Before any host workstation can access an equalized file, the EqualCli program contacts the EqualSrv program running on the filemaster station to ensure that any modifications can be passed to the filemaster copy. If, for some reason, EqualCli cannot make contact with EqualSrv, the operator will receive an error message and will not be able to access the equalized file. This ensures that no updates to the file are lost. If EqualCli makes contact with EqualSrv, the operator is permitted to access and modify the equalized file. EqualCli passes the updates to EqualSrv, who then updates the filemaster copy. If the update is successful, EqualSrv will make the file available to all the host workstations. There are three events which trigger the file equalization procedure. When I/NET is launched on any host workstation. When an operator attempts to access an equalized file. When any operator successfully updates an equalized file.

Issue Are NPR 2000s designed to withstand more rigorous conditions than PCs? Environment I/NET Site Cause Are NPR 2000s designed to withstand more rigorous conditions than PCs? Resolution Yes. (TCON 209 Series 2000 NetPlus Router, 1-16)

Issue A 7792 is used specifically for what? Environment I/NET site Cause A 7792 is used specifically for what? Resolution It is the interface to Micro Regulators (MRs) and Application Specific Controllers (ASCs), (TCON 209, 1-21)

Issue A 7793 is used specifically for what? Environment I/NET site Cause A 7793 is used specifically for what? Resolution A 7793 is the interface for Micro Regulators (MRs), Application Specific Controllers (ASCs), and Door Processing Units (DPUs). (TCON209, 1-20).

Issue How many subLAN controllers can a 7798 support? Environment I/NET site Cause How many subLAN controllers can a 7798 support? Resolution A 7798 can support up to 32 MRs, ASC, DPUs, or any combination on a subLAN. (TCON 209,1-23) Please note that if you are using bin file 1.09, the number of controllers is limited to 27.

Issue What type of protocol does I/NET 2000 use? Environment I/NET 2000 Cause What type of protocol does I/NET 2000 use? Resolution I/NET 2000 uses a proprietary, Token-passing protocol, operating in a tiered LAN architecture. (TCON 209, Communication, 2-1)

Issue Should I use a synchronous modem for integrated dial applications? Environment I/NET site Cause Should I use a synchronous modem for integrated dial applications? Resolution No. The modem should be asynchronous. (TCON209, 2-10)

Issue Can a asynchronous modem communicate to a 78040 or 78050 Tap? Environment I/NET site Cause Can a asynchronous modem communicate to a 78040 or 78050 Tap? Resolution No. These are synchronous only Taps. (TCON 209, 2-14)

Issue Do I need to replace the EPROM on the MIP in my 7760? Environment I/NET site Cause Do I need to replace the EPROM on the MIP in my 7760? Resolution No. (TCON 209, 2-14,15)

Issue Can I set up Auto Dial Auto Answer (ADAA) on a Host without using a 78041 Tap? Environment I/NET site Cause Can I set up Auto Dial Auto Answer (ADAA) on a Host without using a 78041 Tap? Resolution Yes. I/NET 2000 allows the host workstation to emulate a 78041 Tap. (TCON 209, 2-15)

Issue What does "AT&F" do to a modem? Environment I/NET site Cause What does "AT&F" do to a modem? Resolution It resets the modem to its factory default. (TCON209, 2-17,18)

Issue When a Dial link is chosen from a System Page, and the Dial Tap associated with the Tap is busy, what will happen? Environment I/NET site Cause When a Dial link is chosen from a System Page, and the Dial Tap associated with the Tap is busy, what will happen? Resolution The system will roll to the next available system Link Tap. (TCON209, Multiple Site Dial Function, 2-23)
