23 Chapter 3 - Software Loading and Configuration 32. Win3.1 users - you are returned to your Program Manager where the MultiFRAD Program Group and Program Item (Windows icons) have been created. Win95/NT users - you are returned to your MultiFRAD 2000 folder which will be visible on your desktop.
24 MultiFRAD II User Guide 37. Click the DLCI you want to map. The Protocol Mappings, Port Mappings, and all the other groups become active. 38. T o map this DLCI to one or more data ports, click (in the Port Mappings group) the desired Data Port number(s) ( 1 and/or 2 ) that you want to associate with this DLCI.
Router/T wo-Port Frame Relay Access Device Chapter 4 - MultiFRAD Software.
26 MultiFRAD II User Guide Introduction This chapter describes the MultiFRAD 2000 software from an applications approach in how the configuration can be changed with recommendations on the impact of that change.
27 Chapter 4 - MultiFRAD Software Download Firmware This utility allows you to download the firmware to the MultiFRAD. This may be necessary in the case of repair or upgrade.
28 MultiFRAD II User Guide MultiFRAD Configuration T o view or change your MultiFRAD configuration in Windows 95/NT , click Start | Programs | MultiFRAD 2000 | MultiFRAD Configuration , or double-click the MultiFRAD Configuration icon in the MultiFRAD 2000 program group.
29 Chapter 4 - MultiFRAD Software IP Setup The IP Setup dialog box enables you change the IP routing capabilities, add or delete logical W ANs, enable the DHCP relay agent, assign DNS server addresses, and define static routes and a default route. The initial routing capabilities were established during the software installation.
30 MultiFRAD II User Guide (DHCP) and Domain Name System (DNS) options, the default route, filters, and Static Routes. In most cases, you should not have to change the value of any timer (default TTL, reassembly timeout, RIP response time, or RIP route aging time).
31 Chapter 4 - MultiFRAD Software IPX Setup The IPX Setup dialog box controls the four frame types; the W AN ports setup; and the advanced tab enables IPX routing, enables auto learn of Ethernet network numbers, and specifies the distributed name of the MultiFRAD.
32 MultiFRAD II User Guide both virtual W AN numbers have to be the same and unique. In a frame relay configuration, the logical W AN network number has to be the same and unique at both ends of the Permanent V irtual Circuit (PVC).
33 Chapter 4 - MultiFRAD Software Spanning T ree Setup When the Bridging Enable option is enabled, the Spanning T ree Setup dialog box controls transparent bridging; however , if there are any loops or redundant links in the internetwork, the Spanning T ree Algorithm Enable option must also be enabled.
34 MultiFRAD II User Guide Statistics The Statistics dialog box enables you to view statistics on the major events of the MultiFRAD. The Statistics dialog box changes depending on the way the W AN port is configured.
35 Chapter 4 - MultiFRAD Software IP Statistics IP is a connection-less network protocol that resides in the network layer of a conventional OSI layered model (for more information on this model, refer to Appendix C). Depending on what is going on at the application layer , IP will typically use one of two transport layer protocols.
36 MultiFRAD II User Guide IPX Port Statistics The IPX Port Statistics dialog box displays information pertaining to the IPX Port; for example, the frame type used or the number of packets transmitted/received. IPX is a network layer protocol usually associated with Novell Netware TM networks.
37 Chapter 4 - MultiFRAD Software SNMP Statistics The SNMP Statistics dialog box provides statistical information on Simple Network Management Protocol (SNMP). SNMP is an application layer protocol that facilitates the exchange of management information between network devices.
38 MultiFRAD II User Guide W AN Statistics The W AN Port Statistics dialog box provides statistical information regarding the MultiFRAD’ s W AN port, including the number of packets transmitted/received, and to transmit, and the number of bytes transmitted/received.
39 Chapter 4 - MultiFRAD Software DLCIs show active at both (or all) locations and there is still an end-to-end communication problem, it is likely that it is in the configuration of the MultiFRAD. At that point, review your protocol stack/data port parameters and DLCI mappings.
40 MultiFRAD II User Guide W AN Port Setup The W AN Port Setup dialog box controls how the port is configured (i.e., for frame relay or point-to- point operation). If the W AN port is configured for frame relay , then the mode of the port is set to Synchronous.
41 Chapter 4 - MultiFRAD Software Point to Point Setup The Point to Point Setup dialog box controls the W AN port protocol, dial on demand, and remote port setup. The W AN port protocol can be either Point to Point Protocol (PPP) or Serial Line Internet Protocol (SLIP).
42 MultiFRAD II User Guide Frame Relay Setup The Frame Relay dialog box displays the CIR Measurement Interval in milliseconds, the Management T ype and details of that management type, and the number of DLCI’s that are active. The MultiFRAD can detect DLCIs and the Management T ype when you are connected to an active frame relay service.
43 Chapter 4 - MultiFRAD Software If you click the DLCI button on the right side of the dialog box, the Frame Relay DLCI dialog box is displayed. If you are connected to a frame relay service, this dialog box should display your current DLCI numbers automatically .
44 MultiFRAD II User Guide Congestion Management, Mode, and CIR/Be settings are used to avoid congestion and possible loss of data. The Committed Information Rate (CIR) and Excess Burst rate (Be) settings are throughput amounts determined by the network and user when each DLCI is ordered.
45 Chapter 4 - MultiFRAD Software When you click the OK button in the IP W AN dialog box, you now have an IP address for a second logical W AN. Now we have to tie that IP address to a DLCI which in our example is DLCI 17. Now , return to the Frame Relay DLCI dialog box and highlight DLCI 17.
46 MultiFRAD II User Guide Data Port Configuration This dialog box lets you leave both data ports enabled for normal data transfer operations or disable a given port if you do not want to transmit or receive data over it. The Destination Port parameter will be active only if both data ports have been mapped to the same DLCI.
Router/T wo-Port Frame Relay Access Device Chapter 5 - Remote Configuration and Management.
48 MultiFRAD II User Guide Introduction This chapter provides procedures for changing the configuration of a remote MultiFRAD unit. Remote configuration enables a PC at one site (local site) to dial a remote MultiFRAD and change the configuration of that remote unit.

74 MultiFRAD II User Guide Channel bank: A device that acts as a converter, taking the digital signal from the T1 line into a phone system and converting it to the analog signals used by the phone system. A channel bank acts as a multiplexer, placing many slow-speed voice or data transactio ns on a single high-speed link.
75 Glossary Device driver: Software that controls how a computer communicates with a device, such as a printer or mouse. Digital Cross-connect System (DCS): The CO device which splits and redistributes the T1 bandwidth. The DCS takes time slots from various T1 lines and alters them to provide the needed connectivity.
76 MultiFRAD II User Guide Exchange Termination (ET): The carrier's local exchange switch. Contrast with "Loop Termination - LT". Explicit Congestion Management: The method used in frame relay to notify the terminal equipment that the network is overly busy.
77 Glossary Graphical User Interface (GUI): A type of computer interface consisting of a visual metaphor of a real-world scene, often of a desktop. Within that scene are icons, representing actual objects, that the user can access and manipulate with a pointing device.

81 Glossary RJ-45: An 8-wire modular connector for voice and data circuits. Robbed Bit Signaling: The popular T1 signaling mechanism where the A and B bits are sent by each side of the T1 termination and are "buried" in the voice data of each voice channel in the T1 circuit.
82 MultiFRAD II User Guide Synchronous Transmission: The transmission of data which involves sending a group of characters in a packet. This is a common method of transmission between computers on a network or between modems. One or more synchronous characters are transmitted to confirm clocking before each packet of data is transmitted.
83 Glossary Trunk: Transmission links that interconnect switching offices. TSR (terminate and stay resident): A software program that remains active and in memory after its user interface is closed. Similar to a daemon in UNIX environments. Tunneling: Encapsulation data in an IP packet for transport across the Internet.
