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 Multi-

FRAD allows a non-frame relay device to connect to a common carrier

frame relay network service or private frame relay network. The access

device is designed with an internal 56K Data Service Unit (DSU) that

allows a single frame relay permanent virtual circuit (PVC) to be

connected to a 56K DDS circuit. On the receiving end of the communi-

cation link, the MultiFRAD serves to strip away the frame relay control

information in order that the target device is presented with the data

packaged in its original form.

The versatility of the MultiFRAD provides for a smooth integration with

existing equipment; e.g., multiplexers, routers, legacy equipment such

as cluster controllers, and asynchronous devices such as PCs running

remote control software. The non-frame relay device connects to the

data port on the back of the MultiFRAD and is capable of synchronous

data transmission up to 56K bps or asynchronous data transmission up

to 57.6K bps. The network connection is provided by the trunk port

which directly connects to the 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 2 - Front and Back Panel Descriptions

Chapter 2 describes the front panel indicators and back panel connec-

tors. The front panel contains the LEDs for the data and trunk status.

The back panel provides cable connections to the data port, trunk port,

and a power connection for an external power supply.

Chapter 3 - Setup

Chapter 3 provides unpacking instructions, a setup procedure for

connecting cables and direction as to when you should configure the

unit. Also, after the unit is configured and if a V.35 interface is needed

for the data device, a procedure for changing the shunt to the V.35

position is provided.

Chapter 4 - Software Loading and Configuration

This chapter provides procedures on how to load the software utility and

configure the unit when a pc with a Windows application is connected to

the MultiFRAD. If a dumb terminal is connected to the MultiFRAD, the

unit can still be configured using the ASCII terminal menu system that is

present in the memory of the unit.

Chapter 5 - Software Utility Descriptions

This chapter provides a complete description of the Windows based

software used on the MultiFRAD 100-Series. From an icon in the

MultiFRAD program group, the Main menu is displayed. From the Main

menu, the data Port and trunk can be configured. Trunk statistics,

diagnostics, and the download feature are also described.

Figure 1-2. Typical Frame Relay Network

A MultiFRAD

is easily connected to a frame relay network. One Data

Link Connection Identifier (DLCI) is required and it is provided by your

local network service provider when you request (subscribe) for a local

telephone line connection. When your local network service provider

engineers your connection, a virtual circuit is established between your

location and the destination of your connection. This virtual circuit is

called a permanent virtual circuit (PVC).

1.3.1 Ordering a Frame Relay Line

Ordering frame relay services from your local telephone company

involves connecting the physical line, defining the port connection,

configuring the PVC through the network, and assigning the Data Link

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. When a PVC is assigned, an average guaran-

teed throughput is negotiated with the service provider. The guaranteed

throughput is called committed information rate (CIR) and is based on

13

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. Finally during subscription, the management type

is defined by the local frame relay service provider. The management

type is a mechanism for communicating the status of the PVC and is

dependent upon which type is running on the telephone switch. Three

types of management are supported by the MultiFRAD: local manage-

ment interface (LMI), Annex A, and Annex D.

1.3.2 How to Configure a MultiFRAD

Configuring a MultiFRAD is a simple process of defining the data port

device and the trunk parameters for frame relay. To configure a Multi-

FRAD, a pc has to be connected to the Data port on the MultiFRAD and

the MultiFRAD software loaded. To define the data port, the type of

device that is connected to it has to be defined. If the device is a

synchronous device such as a multiplexer, then the clocking and speed

of the device have to be defined in the Data Port Configuration dialog

box. A couple of other parameters also have to be set in order for the

multiplexer to communicate with the MultiFRAD.

If the data device is an asynchronous device, the Asynchronous Mode

option button changes the dialog box to display the asynchronous

parameters. The async parameters are the normal baud rate, word

14

length, parity, stop bits, and flow control. The Async Data Port Configu-

ration dialog box displays the default parameters that may apply to a

majority async devices.

When the data device is defined, then the trunk configuration needs to

be defined. The trunk configuration is displayed in the Trunk Configura-

tion dialog box. Most of the trunk information is supplied by your

network service provider.

For example, if the MultiFRAD at remote site 2 in our typical Frame

Relay network in Figure 1-2 is being configured, the DLCI is 26, the

Access Rate is 56000, and generally a Committed Info Rate of 32000

with a Excess Burst Rate (Be) of 24000 would allow the multiplexer at

remote site 2 to communicate with the host site. These parameters can

be added to the Trunk Configuration dialog box with a Management

Type defined by your network service provider, lets say for this example

that it is LMI. The default Management Parameters in the Trunk Configu-

ration dialog box for the most part should work for this typical applica-

15

tion. The trunk configuration would be complete by clicking on the Save

button and returning to the Main menu. In the Main menu, click on the

download button to transfer the configuration to the MultiFRAD. Within a

few seconds the new configuration is downloaded to the MultiFRAD and

it is ready for operation.

1.4 FCC Regulations for Telephone Line Intercon-

nection

1. This equipment complies with Part 68 of the FCC rules. On the

outside surface of this equipment is a label that contains, among other

information, the FCC registration number and ringer equivalence

number (REN). If requested, this information must be provided to the

telephone company.

2. As indicated below the suitable jack (USOC connecting arrange-

ment) for this equipment is shown. If applicable, the facility interface codes

(FIC) and service order codes (SOC) are shown.

3. The ringer equivalence number (REN) is used to determine the

quantity of devices which may be connected to the telephone line.

Excessive RENs on the telephone line may result in the devices not

ringing in response to an incoming call. In most, but not all areas, the

sum of the RENs should not exceed five (5.0). To be certain of the

number of devices that may be connected to the line, as determined by

the total RENs, contact the telephone company to determine the

maximum REN for the calling area.

4. If this equipment causes harm to the telephone network, the tele-

phone company will notify you in advance. But if advance notice isn’t

practical, the telephone company will notify the customer as soon as

possible. Also, you will be advised of your right to file a complaint with

the FCC if you believe it is necessary.

5. The telephone company may make changes in its facilities, equip-

ment, operations, or procedures that could affect the operation of the

equipment. If this happens, the telephone company will provide ad-

vance notice in order for you to make necessary modifications in order

to maintain uninterrupted service.

6. If trouble is experienced with this equipment (the model of which is

indicated below) please contact Multi-Tech Systems, Inc. at the address

shown below for details of how to have repairs made. If the trouble is

causing harm to the telephone network, the telephone company may

request you remove the equipment from the network until the problem is

resolved.

1.5 Canadian Limitations Notice

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 telephone interface. The

termination of a 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.

Notice: The Industry Canada label identifies certificated equipment. This

certification means that the equipment meets certain telecommunica-

tions network protective, operational and safety requirements. The

Industry Canada does not guarantee the equipment will operate to the

user’s satisfaction.

Before installing this equipment, users should ensure that it is permis-

sible to be connected to the facilities of the local telecommunications

company. The equipment must also be installed using an acceptable

method of connection. The customer should be aware that compliance

with the above conditions may not prevent degradation of service in

some situations.

Repairs to certified equipment should be made by an authorized

Canadian maintenance facility designated by the supplier. Any repairs

or alterations made by the user to this equipment, or equipment

malfunctions, may give the telecommunications company cause to

request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground

connections of the power utility, telephone lines and internal metallic

water pipe system, if present, are connected together. This precaution

may be particularly important in rural areas.

Caution: Users should not attempt to make such connections them-

selves, but should contact the appropriate electric inspection authority,

or electrician, as appropriate.
