Chapter 4 - MultiFRAD Software
MultiFRAD User Guide Introduction This chapter describes various features of the MultiFRAD software that enable you to change (update) the configuration of your MultiFRAD. The basic configuration parameters were established during the loading of the software (Chapter 3). The MultiFRAD software and configuration utilities described in this chapter enable you to change that initial configuration as necessary. The primary interface to the MultiFRAD software is a main menu (with MultiFRAD v3.
Chapter 4 - MultiFRAD Software MultiFRAD Configuration To view or change your MultiFRAD configuration in Windows 95/NT, click Start | Programs | MultiFRAD 200 | MultiFRAD Configuration, or double-click the MultiFRAD Configuration icon in the MultiFRAD 200 program group. After loading, the MultiFRAD main menu will appear. The MultiFRAD main menu consists of 12 buttons in which you can point and click, an Events window, and a status bar.
MultiFRAD User Guide Changing IP Parameters The IP Setup dialog box enables you change the IP routing capabilities, add or delete logical WANs, 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. You can change IP routing parameters by clicking on the Advanced tab and changing, for example, the RIP Response Time or RIP Route Aging Time.
Chapter 4 - MultiFRAD Software The Advanced tab on the IP Setup dialog box controls the timers, Dynamic Host Configuration Protocol (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 time-out, RIP response time, or RIP route aging time). If you are using Default Routing, disable RIP based routing, then enter the IP host address of the “next hop.
MultiFRAD User Guide Changing IPX Parameters The IPX Setup dialog box controls the four frame types and the WAN ports. The Advanced tab enables IPX routing, enables auto learn of Ethernet network numbers, and specifies the distributed name of the MultiFRAD. The RIP and SAP default timers should not have to be changed for most applications. Disabling IPX and SPX Watchdog Spoofing in the Bandwidth Optimization group has proven effective under certain circumstances with Citrix clients.
Chapter 4 - MultiFRAD Software The IPX WAN network number has to be the same on both ends of the link and must be unique throughout the internetwork. If the WAN port is configured in a point-to-point operation, both WAN network numbers have to be the same and unique. If the WAN port is configured for frame relay, both logical WAN network numbers have to be the same and unique.
MultiFRAD User Guide Spanning Tree Setup When the Bridging Enable option is enabled, the Spanning Tree Setup dialog box controls transparent bridging; however, if there are any loops or redundant links in the internetwork, the Spanning Tree Algorithm Enable option must also be enabled. Spanning Tree is a method of transparent bridging, as opposed to source route bridging which the MultiFRAD does not support. The MultiFRAD defaults with one logical WAN port mapped to a DLCI.
Chapter 4 - MultiFRAD Software 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 WAN port is configured. If the MultiFRAD is configured for point-to-point operation, the button to the right of the WAN button changes from “Frame Relay” to “PPP” and the DLCI button will no longer be active.
MultiFRAD User Guide 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.
Chapter 4 - MultiFRAD Software 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 NetwareTM networks. It allows for encapsulation of four different frame types over a single physical LAN connection (provided each frame type has a unique network address): RAW (802.3), LLC (802.2), Ethernet II, and SNAP.
MultiFRAD User Guide 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. There are three key components in SNMP: the devices that are to be managed, agents, and the network management systems. The managed device is the network device, such as a router.
Chapter 4 - MultiFRAD Software Frame Relay Statistics The Frame Relay Management Statistics dialog box can be a useful tool for troubleshooting MultiFRAD installations and monitoring the performance of active links, and checking that the MultiFRAD is talking to the provider’s switch. The Polling Details section lists the various management frames sent and received. For every Status Enquiry Sent, a Status Response should be received from the network.
MultiFRAD User Guide When troubleshooting a frame relay circuit, once it has been established that management frames are being sent and received, the next step is to determine whether the DLCIs are becoming active. This dialog box will provide that information. A FRAD needs to be present at both ends for the DLCI to be active. Keep in mind that the frame relay network tells the FRAD the status of the PVC with one of its status responses.
Chapter 4 - MultiFRAD Software These statistics may indicate that either the data channels, or more likely the devices attached to them, are being driven harder than they should be. Excessive buffer utilization and/or receive flow control time can usually be reduced or eliminated by slowing the speed at which the channel is operating.
MultiFRAD User Guide Call Progress Statistics (FR221/V2 Only) The Call Progress Statistics dialog box displays statistical information for the current activity, such as a call in progress. A drop-down list enables you to select which channel you want to monitor. After a channel is selected, all the relevant data for the current activity on that channel will be displayed in the fields provided. Note: the Packets Sent and Bytes Sent are for the local side of the current call.
Chapter 4 - MultiFRAD Software WAN Port Setup The WAN Port Setup dialog box selects whether the DSU port is enabled or not and controls how this port is configured (i.e., for frame relay or for point-to-point operation). For Frame Relay operation, you can ignore everything in the Mode and Connection Method groups on this dialog box. For point-topoint operation, the FR221/V2 voice/fax channels are not operational.
MultiFRAD User Guide Point-To-Point You can check communication between two MultiFRADs by cabling their DSU ports together with an RJ-45 cable, selecting point-to-point operation (PPP/SLIP), enabling DSU Loop Back, and setting one MultiFRAD to Internal Clocking and the other one to DDS. Data applied to the DSUs will be reflected both ways. Further configuration for point-to-point operation can be set up by clicking the PPP button on the main menu.
Chapter 4 - MultiFRAD Software Point to Point Setup The Point to Point Setup dialog box controls the WAN port protocol, dial on demand, and remote port setup. The WAN port protocol can be either Point to Point Protocol (PPP) or Serial Line Internet Protocol (SLIP). PPP is the more robust of the two protocols in that it enables the endpoints to negotiate use of the link and protocol parameters in a standardized way and also provides for standardized encapsulation of the packets.
MultiFRAD User Guide Frame Relay Setup The Frame Relay dialog box displays the CIR Measurement Interval in milliseconds, the Management Type and details of that management type, and the number of DLCI’s that are active. The MultiFRAD can detect DLCIs and the Management Type when you are connected to an active frame relay service. So it is important that if you change any frame relay parameters, that the new parameters agree with the way your frame relay service is provisioned.
Chapter 4 - MultiFRAD Software If you are connected to a frame relay service, this dialog box should display your current DLCI numbers automatically. It also shows the protocol mapping of the highlighted DLCI, which data ports are mapped to it, and how you set up your Congestion Management, Mode, CIR, and Be values. To change the mapping of a DLCI, highlight the DLCI number in the list on the left side of the dialog box. The dialog box will then change to the mapping of that DLCI.
MultiFRAD 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. The CIR is the basic throughput which the network will try to set aside for that DLCI. It will always be equal to or less than the actual access rate of the physical line (i.e.
Chapter 4 - MultiFRAD Software When you click the OK button in the IP WAN dialog box, you now have an IP address for a second logical WAN. 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. Click the Protocol Mappings Map IP Address down arrow and the IP address 192.168.2.1 appears. Click this address and now IP address 192.168.2.1 is mapped to DLCI 17. We now have WAN IP address 192.168.2.
MultiFRAD User Guide Packet Priority Three levels of priority (High, Medium, and Low) are supported for data packets (i.e., IP packets, IPX packets, and STP packets), whether in frame relay or point-to-point mode. When priority levels are in use, the packets are processed based on their priority setup.
Chapter 4 - MultiFRAD Software 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. For point-to-point operation, only APSM mode will be enabled. For frame relay operation, APSM mode allows both data ports and any protocol stacks to be mapped to a single DLCI.
MultiFRAD User Guide Changing Channel Parameters (FR221/V2 only) Click the Voice Channels button on the main menu to display the Voice/Fax Channel Setup dialog box. The Interface tab is the default tab that appears whenever this dialog box is opened. The other two tabs contain voice and fax settings and the voice communications Tone Pairs for the MultiFRAD. Interface The Interface tab defines the interface type used on each voice/fax channel.
Chapter 4 - MultiFRAD Software The Max Dial Digits field in the Dialing Options group indicates the longest phone number you can enter in the phone directory database. The value shown in this field is the maximum number of digits permitted in any phone number entered into the database. It does not represent an actual phone number. The range for the Maximum Dial Digits is 1 to 16 digits, and the default is 5 digits.
MultiFRAD User Guide Voice/Fax (FR221/V2 only) The Voice/Fax tab controls the voice coder, Fax settings, DTMF gain, and some miscellaneous options. The MultiFRAD supports numerous state-of-the art ITU (International Telecommunications Union) voice coders. The Voice Coder drop-down menu enables you to select from a range of coders with specific bandwidths. The higher the bps rate, the more bandwidth is used.
Chapter 5 - Remote Configuration and Management Regional (FR221/V2 only) The Regional tab controls the voice communications for the country or region in which the MultiFRAD is being used. From the Country/Region drop-down list you can select the country or region for which you are configuring the MultiFRAD. The Tone Pairs group always displays the tones used in the country or region currently selected.
MultiFRAD User Guide Changing the Phone Directory Database (FR221/V2 only) Clicking the Phone Book button on the main menu displays the Phone Directory Database dialog box, which displays the phone numbers of all the MultiFRADs in your network. The Station Phone Number field on this dialog box lists the phone numbers in numerical order.

Appendix C - Network Overview Canadian Limitations Notice Ringer Equivalence Number Notice: The ringer equivalence number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a phone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the ringer equivalence numbers of all the devices does not exceed 5.
MultiFRAD User Guide Appendix C - Network Overview Network architecture defines how computer equipment and other devices are linked together to form a communications system that enables users to share information and resources. There are proprietary network architectures and open architectures like the Open Systems Interconnection (OSI) model defined by the International Organization for Standardization (IOS).
Appendix C - Network Overview including more sophisticated error handling, prioritization, and security features. It provides quality service and accurate delivery by providing connection-oriented services between two end systems. The transport layer controls the sequence of packets, regulates traffic flow, and recognizes duplicate packets. It assigns packetized information which is a tracking number that is checked at the destination.
MultiFRAD User Guide different destination address, and in some cases, different sizes. A typical packet holds 512 bytes of information, so it takes many packets to transfer a large file over a network. As packets traverse a network, the addressing information contained in them is used by bridges and routers to direct packets to their destination, or keep them off of networks where they don't belong.
Appendix C - Network Overview IP Addressing Every node on an IP network requires a 4-byte numeric address that identifies both a network and a local host or node on the network. This address is written as four numbers separated by dots, for example, 148.1.9.1. In most cases, the network administrator sets up these addresses when installing a device.
MultiFRAD User Guide Appendix D - Disabling the Internal DSU Perform the following procedure if your WAN network has been upgraded to T1/E1 and you now want to disable the MultiFRAD’s internal DSU and use the back panel Trunk connection to obtain data rates of up to 2.048 Mbps. 1 Turn off the MultiFRAD using the back panel Power switch. 2 Locate the access window (side slot opening) near the left front corner of the MultiFRAD.
Glossary
MultiFRAD User Guide A Access: The T1 line element made up of two pairs of wire that the telephone company brings to the customer premises. The Access portion ends with a connection at the local telco (LEC or RBOC). Accunet Spectrum of Digital Services (ASDS): The AT&T 56K bps leased (private) line service. Similar to services of MCI and Sprint. ASDS is available in nx56/64K bps, where n=1, 2, 4, 6, 8, 12.
Glossary Basic Rate Interface (BRI): An ISDN access interface type comprised of two B-channels each at 64K bps and one D-channel at 64K bps (2B+D). Bell Operating Companies (BOC): The family of corporations created during the divestiture of AT&T. BOCs are independent companies which service a specific region of the US. Also called Regional Bell Operating Companies (RBOCs).
MultiFRAD 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 transactions on a single high-speed link. Circuit-switched Network: A technology used by the PSTN that allocates a pair of conductors for the exclusive use of one communication path.
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. DCS connections are made with software at an administrator's workstation. Digital Data: Information represented by discrete values or conditions (contrast "Analog Data").
MultiFRAD 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. The use of FECN and BECN is called explicit congestion management. Some end-to-end protocols use FECN or BECN, but usually not both options together. With this method, a congestion condition is identified and fixed before it becomes critical.
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. H Handshaking: A process that two modems go through at the time of call setup to establish synchronization over the data communications link.
MultiFRAD User Guide L LAPB: Link Access Procedure Balanced; based on the X.25 Layer 2 specification. A full-duplex point-to-point bit-synchronous protocol commonly used as a data link control protocol to interface X.25 DTEs. LAPB is the link initialization procedure that establishes and maintains communications between the DTE and the DCE. LAPD: Link Access Protocol for the D-Channel; based on the ISDN Q.921 specification.
Glossary Multiprotocol: A device that can interoperate with devices utilizing different network protocols. Multithreading: The ability of a software system to be able to handle more than one transaction concurrently. This is contrasted to the case where a single transaction is accepted and completely processed before the next transaction processing is started. N Nailed Connection: A permanent or dedicated circuit of a previously switched circuit or circuits.
MultiFRAD User Guide Point of Presence (POP): The central office's end points of the long distance carriers. Point to Point Protocol (PPP): A protocol that lets a PC user access TCP/IP (Internet member) using an ISDN terminal adapter or a high-speed modem over a standard telephone line. Port: A location for input or output data exchange. Computers, muxes, etc. have ports for various purposes. Primary Rate Interface (PRI): Used on ISDN.
Glossary 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. Since the bits are "robbed" infrequently, voice quality is remains relatively uncompromised. See "bit robbing". The robbed-bit signaling technique is used in D4 channel banks to convey signaling information.
MultiFRAD 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. Compare to Asynchronous Transmission.
Glossary Transport Layer: Layer 4 of the Open Systems Interconnection (OSI) model; provides reliable, end-to-end delivery of data, and detects transmission sequential errors. Transport Protocol Data Unit (TPDU): A transport header, which is added to every message, contains destination and source addressing information that enables the end-to-end routing of messages in multi-layer NAC networks of high complexity.
