1 Introduction and Description
1.1 Introduction The Multi-Tech Systems MultiFRAD™ 100-Series, Model number FR111, is a one-port Frame Relay Access Device (FRAD) with 56K DSU that encapsulates non-packetized data from a serial device into frame relay frames and is responsible for framing that data with header and trailer information prior to transmission to a frame relay network. The MultiFRAD allows a non-frame relay device to connect to a common carrier frame relay network service or private frame relay network.
1.2 About This Manual This manual describes the MultiFRAD, and tells you how to install and configure the unit. The information contained in each chapter is as follows: Chapter 1 - Introduction and Description Chapter 1 introduces the MultiFRAD 100-Series. A typical application is presented with a discussion on ordering a frame relay line and how to configure a MultiFRAD. A list of relevant specifications are provided at the end of the chapter.
Chapter 6 - ASCII Terminal Menu System Chapter 6 provides a description of the ASCII terminal menu system. The ASCII terminal menu system is used when a dumb terminal is connected to the data port. These menus allow you to configure the data port and trunk, view statistics, reset the unit, and enable diagnostics.
1.3 A Typical Application A typical application for a MultiFRAD 100-Series is connecting a single non-frame relay device to a frame relay network. The MultiFRAD 100Series is usually used at a remote site where a single DLCI and a single device needs to be connected to a frame relay network. A MultiFRAD 100-Series can connect any existing synchronous or asynchronous non-frame relay device to a frame relay network.
your capability to present data to the local telephone switch. Your capability to present data is determined by the internal DSU (Data Service Unit) that can transfer digital data at a maximum rate of 56,000 bits-per-second to the network. A general rule of thumb in this scenario is to assign a CIR of 32K bps and an excess burst rate (Be) of 24K bps. The sum of the CIR and Be can not exceed your capability to present data to the network.
length, parity, stop bits, and flow control. The Async Data Port Configuration dialog box displays the default parameters that may apply to a majority async devices.

2 Front and Back Panel Descriptions 21
2.1 Introduction This chapter describes the front panel LEDs and back panel connectors. The front panel has one row of LEDs for both the data channel and trunk status. Two back panel connectors provide the data and trunk connections. A circular power connector is provided to connect the external power supply. 2.2 Front Panel The front panel contains two sets of LEDs that provide the status of the data and trunk connections. The data LEDs display the activity of the data port, if V.
received - on for a space and off for a mark. DSU Data Service Unit (DSU) LED lights when the unit is in the DSU-only mode. NS The No Signal (NS) LED lights when no signal is received from the network or when the signal is too weak for normal operation. OOS The Out Of Service (OOS) LED lights when an outage condition occurs. This happens when there is a failure in the digital service that is detected by the network and the telco sends a repetitive OOS sequence.
2.3 Back Panel The cable connections for the MultiFRAD are made at the back panel. Two cable connections are provided and one power supply connection. The Data connector allows the MultiFRAD to be connected to a nonframe relay device and the Trunk connector connects to a common carrier frame relay network service or private frame relay networks. The cable connections are shown in Figure 2-2 and defined in the following sections. Power Data Trunk Figure 2-2.
2.4 Switch Settings The 8-position DIP switch located on the right side of the MultiFRAD only uses the first four positions. The DIP switches are shown in Figure 2-3 and their settings are described in Table 2-1. DIP-Switches Figure 2-3. Switch Settings Table 2-1.
2.5 Shunts V.35 signal levels are generally more reliable for high speed data and/ or longer cable distances. EIA-232D signal levels are intended for data rates of 19,200 bps or less and cable lengths of 50 feet or less. For higher speeds and/or longer distances, V.35 is generally preferred. There are two shunt positions on the printed circuit board that configure the data port for either RS232 or V.35 interface. Both DIP sockets for the shunts are shown in Figure 2-4. V.
3 Setup
3.1 Introduction This chapter describes the unpacking of the MultiFRAD, cable connections depending on whether EIA-232D or ITU-T V.35 interface signaling is used on the data port, and how to configure the unit dependent on your site situation. Once the MultiFRAD is configured, then the data port can be connected to your data port device. 3.2 Unpacking The shipping box contains the MultiFRAD, power adapter, and your owner's manual.

5 Software Utility Descriptions
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.
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. Diagnostics This button allows you to run two loopback tests, a memory test, and watch dog test. 5.2.3 Download You can update the MultiFRAD setup on the target. This will bring the MultiFRAD down for updating the setup.
5.2.5 Help A thorough On-line Help system is provided with abbreviated information on the dialog boxes and the buttons within a dialog box. 5.2.6 MultiFRAD Version The current version number of the MultiFRAD firmware is displayed in this field.
5.3 Data Port Configuration This dialog box allows you to configure the data port. You 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. The data port can operate either in Asynchronous (UART) mode or Synchronous (HDLC) mode. Choose the Mode option that meets your site requirements.
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. The Between Frames determine what happens when the synchronous data line is idle (i.e., no data frames are being transmitted). The default condition is to continuously send SDLC flags (Flags).
CRC Preset The CRC Preset parameter allows the user to specify whether the polynomial 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. Async Mode Parameters Following Parameters are modifiable when the device connected to the data connector on the back of the MultiFRAD 100-Series is an asynchronous device.
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. Flow Control The Flow Control parameter allows for two types of flow control: the software-based XON/XOFF and the hardware-based Clear to Send (CTS). The default is CTS.
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. Echo The Echo parameter enables data entered on the data device keyboard to be returned to the device's monitor.
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).
5.4 Trunk Configuration This dialog box allows you to configure the trunk. You 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. In Frame Relay, frames are routed through the network on the basis of an attached label called a Data Link Connection Identifier (DLCI).
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. Basic LMI protocol is based on a synchronous polling scheme where the user polls the network to obtain status information on the PVCs configured on the interface.
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. The Full Status Counter can range from 1 to 255, with a default of 6. Error Threshold The Error Threshold is used to indicate the threshold number of errors occurring during a full cycle of the Monitored Event.
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. The options are On and Off with a default of Off. Back-to-back mode is useful when two MultiFRADs are at the same location and they are connected via DSUs for testing.
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. If you want to clear the statistics so that you can have fresh statistics, then you should click on the clear button. 5.
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. The data port loopback test has two modes which depend on the device connected to the data port.
6 ASCII Terminal Menu System
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. To select one of the options from the Main Menu, enter the number corresponding to the option and press ENTER.
a message will appear on your screen saying to wait for 3 seconds. Then press ENTER to return to the Main Menu. To store the current configuration, enter S and press ENTER. To return to the Main Menu, enter M and press ENTER. 6.2.1 Async Data Port Configuration The Async Data Port Configuration menu allows you to configure the data channel for either asynchronous or synchronous operation, depending on the type of device connected to the data port.
The Word 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. Under normal conditions, parity is set to none. The default is none. The Flow Control option allows for two types of flow control: the software-based XON/XOFF and the hardware-based Clear to Send (CTS).
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. Since, in normal interactive operation, the existence of a MultiFRAD should be transparent to the user, the EIA pass through option allows a terminal to operate as if it were connected directly to a communications line and not through a MultiFRAD.
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.
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. Refer to the device’s user documentation for the encoding method.
6.2.3 Trunk Configuration The Trunk Configuration menu allows you to configure the trunk.
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. This rate is the average over a minimum increment of time. The CIR may be less than or equal to the Access Rate.
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. The range of this counter is from 1 to 10 events with a default of 4 events. The Encapsulation Mode option depends on the type of device that is connected at the other end of the trunk.
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 : _ To view or clear statistics, enter the corresponding option number and press ENTER. To return to the previous menu, enter P and press ENTER. To return to the Main Menu, enter M and press ENTER. Two Trunk Statistics Menus are provided depending on how the data channel is configured.
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. You will find that the link alarms number will correspond to the retransmit and received frames numbers. Specifically, a link alarm means that it has been 10 seconds since the MultiFRAD has received an acknowledgment. Normally, three acknowledgments are received during a 10second period.
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 2 M P - Reset Unit Reset Data Channel Main Menu Previous Menu Selection : _ To reset the unit, enter 1 and press ENTER. To reset the data channel, enter 2 and press ENTER. To return to the previous menu, enter P and press ENTER. To return to the Main Menu, enter M and press ENTER. 6.
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. This tests the integrity of the local data device, MultiFRAD, and the frame relay network. The Remote Trunk Loopback test is the most sophisticated of the two tests.
try going back to the Local Trunk 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 Tech support. 6.5.2 Memory Test The memory test verifies that each memory chip on the circuit board is working. The memory test destroys all stored parameters. 6.5.3 Watch Dog Test The watch dog is a special circuit designed to reset the unit in case of a catastrophic error in the firmware.
