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

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

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.
