  • Page 9: Introduction

    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.

  • Page 10: About This Manual

    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.
  • Page 11 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 diagnos- tics.

    Connection Identifier (DLCI). The DLCI is a number between 16 and 1007 that identifies the PVC between your MultiFRAD and the phone company's switch. The DLCI is assigned at the same time your local service provider defines the permanent virtual circuit (PVC) that is the path to your destination.
  • Page 13 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.

    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 non- frame relay device and the Trunk connector connects to a common carrier frame relay network service or private frame relay networks.

  • Page 26: Switch Settings

    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. Figure 2-3. Switch Settings Table 2-1.

  • Page 27: Shunts

    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.

Mode Asynchronous/Synchronous This allows you to set synchronous or asynchronous parameters required for transferring data between the MultiFRAD and the data port device.
  • Page 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.

    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.

  • Page 59: Flow Control

    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).
  • Page 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. Echo The Echo parameter enables data entered on the data device keyboard to be returned to the device's monitor.
  • Page 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).

  • Page 62: Trunk Configuration

    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).

  • Page 63: Polling Interval

    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.
  • Page 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. The Full Status Counter can range from 1 to 255, with a default of 6.

  • Page 65: Back To Back

    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.

  • Page 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. 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.
