These settings are located in the Microgate Frame Relay Adapter properties of the Device Manager.
Port Selection
The frame relay virtual adapter is software that uses a port on a hardware adapter. See the section below for details on adding and configuring hardware adapters and ports. Select the hardware port used for this virtual network adapter. Available ports are listed in the pull down port list.
Port Data Rate
The port data rate is the speed in bits per second (bps) in which data is transferred over the physical serial port that connects the hardware adapter to the communications device (CSU/DSU, Modem, etc.).
Examples:
V.34 Modem28800bps
Leased DDS I CSU/DSU56000bps
Bonded ISDN (2 B-Channels)128000bps
T-1 CSU/DSU1544000bps
Incorrectly setting this parameter could result in network timeouts.
Generate Clock
The data clocks are usually provided by the attached modem or CSU/DSU. In rare instances, it may be necessary for the adapter to generate these clocks. Enable this check box if the adapter needs to generate the data clocks. The clock signal is output on the AUXCLK serial signal. Depending on the application, external cabling may be necessary to route the AUXCLK signals to the correct RCLK and TCLK signals.
PVC Management Protocol
The PVC management protocol controls and monitors the virtual circuits on a frame relay connection. The type of protocol is specified by your network provider at subscription time. The most common protocol in the U.S. is ANSI T1.617 Annex D, which is sometimes referred to as simply Annex D. In Europe, a common protocol is Q.922 Annex A or just Annex A. The default protocol is Annex D.
Poll Interval
The PVC management protocol sends a keep alive or full status request packet once per poll interval. The default value of 10 seconds works with most applications. Some networks or remote equipment may require reducing this value. If virtual circuits frequently change between active and inactive, try reducing this setting to 8 seconds.
Full Status Interval
The PVC management protocol sends a keep alive packet every polling interval. After sending the number of keep alive packets specified by this setting, the adapter sends a full status request. A full status request detects virtual circuit state changes. Reducing this setting detects state changes more quickly, but consumes more bandwidth. The default value of 6 works with most applications.
Congestion Logging
Enables or disables Congestion Logging of congestion status changes for all virtual circuits associated with the physical adapter.
Adding and Configuring Hardware Adapters and Ports
Hardware adapters must be installed and configured before being used by the frame relay software. Adapters may have one or more ports. Each frame relay virtual adapter uses a single port. The installation and configuration procedures differ depending on the version of Windows.
Windows uses the hardware install wizard and device manager to install and configure hardware. PCI adapters are automatically detected by Windows, which starts the install wizard. Follow the wizard instructions to search for the hardware drivers on the frame relay disk.
