5 Software Utility Descriptions.
52.
53 5.1 Introduction This chapter describes the MultiFRAD software which is designed for the Microsoft ® Windows ® environment. The MultiFRAD 100 Program Group has three icons that allow you to launch the software, download a firmware update, and configure the console pc port in order to communicate with the MultiFRAD.
54 5.2 .1 Configuration Data Port This button allows you configure the data port for either synchronous or asynchronous mode of operation. Trunk This button lets you define the frame relay parameters. 5.2.2 Others Statistics This button allows you to view statistics of the trunk port.
55 5. 2 .5 Help A thorough On-line Help system is provided with abbreviated informa- tion on the dialog boxes and the buttons within a dialog box. 5.2 .6 MultiFRAD V ersion The current version number of the MultiFRAD firmware is displayed in this field.
56 5.3 Data Port Configuration This dialog box allows you to configure the data port. Y ou will be able to set the parameters required for the successful operation of the port. Mode Asynchronous/Synchronous This allows you to set synchronous or asynchronous parameters required for transferring data between the MultiFRAD and the data port device.
57 Note: The MultiFRAD always provides the clocking signal to the sync device. The MultiFRAD 100's data port can not be set to external clocking, it is always internal clocking. Between Frames The Between Frames parameter must be set to match the idle condition of the synchronous device connected to the data port.
58 CRC Preset The CRC Preset parameter allows the user to specify whether the polyno- mial used to calculate the CRC for each frame is preset to all 1s or all 0s. This option must match the synchronous device’s CRC-preset setting. The default is All 1s.
59 Parity The Parity parameter sets parity for odd, even or none. Under normal conditions, parity is set to none. The default is none. Stop Bits The Stop Bits parameter sets the number of stop bits. The number of stop bits can be 1, 1.5, or 2. The default is 1 bit.
60 Pass Xon The Pass Xon parameter enables the XON/XOFF flow control signals to be passed on to the data device. This option has to be used in conjunction with the software-based XON/XOFF flow control option. The default condition is for this option to be turned off, and normally it should remain off.
61 ENQ/ACK The Enq/Ack parameter is a special flow control protocol used in Hewlett Packard computer systems. This option is sometimes referred to as Enquire/Acknowledge flow control because it’s based on the computer sending an enquiry (ENQ) and then expecting an acknowledgment (ACK).
62 5.4 T runk Configuration This dialog box allows you to configure the trunk. Y ou will be able to set the parameters required for the successful operation of the trunk. Frame Relay is a multiplexing protocol designed to operate over transmission facilities that are virtually error free.
63 LMI describes a protocol and associated procedures operating on the local interface between the user and the network. It notifies the user of the addition, deletion, and presence of the PVC in the network. It also notifies the user of the end-to-end availability or unavailability of a PVC.
64 Full Status Counter The Full Status Counter determines how may Polling Intervals take place before a full status is requested from the network. A full status enquiry message is sent from the MultiFRAD to the network requesting a status report of the PVC on the physical link.
65 Back to Back The Back to Back is used to test the port by connecting two MultiFRADs together without a frame relay network in between them. Back-to-back mode still requires the use of DSU/CSUs, but they should not be connected over the frame relay network.
66 5.5 Statistics This dialog box allows you to view status of the trunk. Its possible to view signal status and other characteristics like data frames transmitted or received, status of enquiries transmitted and messages received and the status of the messages received.
67 Loop Tests The loop tests provide a short and long loop test. The short loop test is the data port loopback test which loops back the data from the data port to the sending device (DTE). The long loop test is the trunk loopback test which again receives data from the DTE device and loops it back from the internal DSU.

6 ASCII T erminal Menu System.
70.
71 6.1 Introduction The menu system for the MultiFRAD provides a set of user-friendly configuration menus that are accessible from a main menu. The Main Menu contains five options that allow you to configure your MultiFRAD; display statistics; reset the unit or data port; run diagnostic tests, and exit the command mode.
72 a message will appear on your screen saying to wait for 3 seconds. Then press ENTER to return to the Main Menu. T o store the current configuration, enter S and press ENTER.
73 The W ord Length option sets the number of bits in a word. The word length range is 5 to 8 bits. The default is 8 bits. The Stop Bits option sets the number of stop bits. The number of stop bits can be 1, 1.5, or 2. The default is 1 bit. The Parity option sets parity for odd, even or none.
74 The EIA Pass Through option allows the data device to receive EIA control signals through the MultiFRAD. This option only applies during the async mode of operation.
75 6.2 .2 Sync Data Port Configuration The Sync Data Port Configuration menu allows you to configure the data port for either asynchronous or synchronous operation, depending on the type of device connected to the port.
76 ing, data is represented normally . With NRZI encoding, a logical one is represented by no transition and a zero is represented by a transition at the beginning of the bit. Most synchronous devices can be configured for either NRZ or NRZI. If a synchronous device is not configurable, it most likely is set to NRZ.
77 6.2 .3 T runk Configuration The T runk Configuration menu allows you to configure the trunk. The default parameters are displayed in the following menu: T runk Configuration 1 - Access rate: 56000 .
78 access circuit. Set the DLCI to indicate the PVC to terminate the trunk. The range of DLCIs is from 16 to 1007 with a default of 16. The Committed Info Rate (CIR) option determines the data transfer rate at which the network is committed to handle under normal conditions.
79 should be less than or equal to the Monitored Event Counter . The Monitored Event Counter option determines the number of Polling Intervals that have to take place before the User Network Interface is operational. It is also used with the error threshold count to determine if the trunk should be brought down.
80 6.3 Statistics The Statistics menu allows you to view or clear statistics, or return to the previous menu or to the Main Menu. Statistics 1 - View Statistics 2 - Clear Statistics M - Main Menu P - Previous Menu Selection : _ T o view or clear statistics, enter the corresponding option number and press ENTER .
81 you might encounter could be 10,000 frames transmitted (or received) with 500 or 1000 retransmits (or receive errors). Link alarms simply tell you that there is some sort of problem on the trunk in async mode. Y ou will find that the link alarms number will correspond to the retransmit and received frames numbers.
82 6.4 Reset Options The Reset Options menu allows you to reset the unit, the data channel, or return to the previous menu or to the Main Menu. Reset Options 1 - Reset Unit 2 - Reset Data Channel M - Main Menu P - Previous Menu Selection : _ T o reset the unit, enter 1 and press ENTER .
83 loopback mode (DIP-Switch 3 DOWN). This tests the complete path through the MultiFRAD up to the line circuitry and back to the data port. When it is used in a remote trunk loopback test mode, the remote DSU (or the telephone company's central office, CO) would be put into loopback mode.
84 try going back to the Local T runk Loopback, and then even the data port loopback which is the most basic test. If there is still no clear cause of the problem, follow the steps in section 7.3, contacting T ech support. 6.5 .2 Memory T est The memory test verifies that each memory chip on the circuit board is working.
