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. 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 communication 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.

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 guaranteed throughput is negotiated with the service provider. The guaranteed
throughput is called committed information rate (CIR) and is based on
12
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 management 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 MultiFRAD, 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
13
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.
When the data device is defined, then the trunk configuration needs to
be defined. The trunk configuration is displayed in the Trunk Configuration 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 Configuration dialog box for the most part should work for this typical applica14
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.

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.35 Shunt Position
RS232 Shunt Position
Figure 2-4. Shunts
In Figure 2-3, the shunt is shown in the RS232 (default) position (i.e., in
the right-hand DIP socket - the one closest to the DIP switches. To
change the location of the shunt, refer to the V.35 Shunt procedure in
Chapter 3.

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. Inspect the contents for signs of any shipping damage.
If damage is observed, do not power up the unit, contact Multi-Tech's
Technical Support for advice (refer to Chapter 7 - Warranty). If no
damage is observed, place the MultiFRAD in its final location and verify
the signal levels (EIA-232D or ITU-T V.35) for the data port, and connect
your cables, phone lines, and power supply.
3.3
Safety Warnings
1. Never install telephone wiring during a lightning storm.
2. Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
3. Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
4.
Use caution when installing or modifying telephone lines.
5. Avoid using a telephone (other than a cordless type) during an
electrical storm. There may be a remote risk of electrical shock
from lightning.
6. Do not use the telephone to report a gas leak in the vicinity of the
leak.

Setup
Use the following steps to setup your MultiFRAD. If V.35 electrical
interface signaling is required on the data port, but a pc with EIA-232D
signaling is being used to configure the MultiFRAD, the unit has to be
configured before you change to V.35 signaling. Perform the following
procedure to connect your cables, configure the unit, and then change
to V.35 signaling on the data port.
1. Ensure that the DIP-Switch settings on the side of the unit are set
for a command mode of operation. Refer to the Switch Settings in
Chapter 2.
DIP-Switches

5. The MultiFRAD can be configured in two ways: If a pc running a
Windows software is being used to configure the unit, refer to the
Software Loading procedure in Chapter 4.
If a terminal running a communications software is being used to
configure the unit, refer to Configuring your MultiFRAD using a
dumb terminal in Chapter 5.
6. Once the MultiFRAD is configured for your application, you can
disconnect the pc and connect your data port device. If the data
port device contains an EIA-232D interface, the same serial cable
can be used. If the data port device contains a V.35 interface, the
data port shunt must be moved to the V.35 position and a V.35
adapter cable must be connected to the data port connector. Refer
to Section 3.5 for procedures on moving the shunt to the V.35
position. Refer to Appendix A for cable details.
7. Place the Command Mode switch (Switch 1) on the side of the
MultiFRAD in the UP position for the data mode operation.

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.
The MultiFRAD 100 Configuration icon allows you to configure the data
port for either a synchronous or asynchronous device, configure the
trunk for a frame relay network, view statistics of the data port, perform
diagnostic test of the unit, and download a new configuration to the unit.
The Download Firmware allows new operating code (firmware) to be
transferred to the MultiFRAD. The Configuration Port Setup icon
establishes the parameters for which the console pc communicates with
the MultiFRAD.
You may also start the MultiFRAD 100 Configuration from the File
Manager by selecting the unofrad directory and double clicking on the
unofrad.exe program in the file list.
You may also run MultiFRAD 100 Configuration from either the Program
Manager or the File Manager by clicking on the Run command in the
File Menu, then typing: C:\unofrad\unofrad.exe in the Command Line
field.

55
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. Both data port modes are discussed in the
following sections.
Sync Mode Parameters
The following parameters are modifiable when the device connected to the
data port connector on the back of the MultiFRAD 100-Series is a synchronous device. To change a parameter, click on the option button to be
activated. To change a parameter using a drop down menu, click on the
drop down arrow and a drop down menu displays the new parameters.
Click on the desired parameter.
Speed
The Speed parameter needs to be set to match the speed of the sync device.
When the data port is connected to a synchronous device, the baud rate is
from 300 bps to 56K bps. The default port speed is 56K bps.
56
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). The other condition is the mark state (Mark). The
transmit LED will be off during idle time if the synchronous device is in the
mark state during idle conditions.
Encoding Scheme
The Encoding Scheme parameter refers to the fact that synchronous data
can be encoded by using either NRZ (Non-Return to Zero) or NRZI (NonReturn to Zero Inverted) method. This parameter must match the synchronous device’s encoding. The default is NRZ. With NRZ encoding, the data
is represented normally. With NRZI encoding, a logical one is represented
by no transmission 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.
InterFrame Timer (in mS)
The InterFrame Timer parameter can be changed to make the MultiFRAD
wait a specified length of time between frames. You can choose Off and
delay times of 2,5,10 and 15 milliseconds. A typical use for this parameter
is to simulate transmission delays encountered with equipment that toggles
hardware signals after transmission of each frame, like PC cards used to
connect to legacy systems. The following options can be specified for the
timer: Off, 2mS, 5mS, 10mS, and 15mS. The default is off.
57
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. To change a parameter using a drop down menu, click on the
drop down arrow and a drop down menu displays the new parameters.
Click on the desired parameter. To change an option parameter, click on
the option box. An "x" appears in the option box if the option is active.
Baud Rate
The Baud Rate parameter needs to be set to match the speed of the async
device. The baud rate ranges from 300 bps to 57.6K bps. The default port
speed is 19.2k bps.
Word Length
The Word Length parameter sets the number of bits in a word. The word
length range is 5 to 8 bits. The default is 8 bits.
58
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. Flow control is the means by which data flow from the
device into the MultiFRAD is controlled. Flow control is necessary when the
data handling capacity of the data port cannot keep up with the volume of
data sent to it. When the data device controls data flow to itself, it is called
pacing (see Pacing). The combination of flow control from the port device
and pacing to the data device is how data transfers are regulated so that
no data is lost.

Pacing
The Pacing parameter controls the data flow to the data device. Pacing is
necessary when the flow of data to a device operating on the data port is
more than it can process. If the device cannot process the volume of data
sent to it, then the pacing option should be turned on. The pacing method
used is determined by the type of flow control. The default condition is for
this option to be turned off.
59
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. The purpose of this option is so that an
operator will not experience undue delays in seeing entered data appear
on their monitor. The default condition for the echo option is off.
EIA Pass Through
The EIA Pass Through parameter allows the data device to receive EIA
control signals through the MultiFRAD. 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. This is done
by allowing selected pins (signals) on one MultiFRAD to be passed through
to selected pins on a remote MultiFRAD. The default condition is for this
option to be turned off. The following diagram shows how the EIA pass
through option routes the selected signals:

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).

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). Frame Relay combines
the bandwidth efficiency of packet switching with end-to-end protocol
transparency, increased speed and performance.
Data Link Connection Identifier (DLCI)
The DLCI is the identification of a particular logical link in the Frame Relay
network and has local significance only. The DLCI is assigned by the frame
relay service provider for the PVC (Permanent Virtual Circuit) that is on your
access circuit. As the logical link traverses the Frame Relay network, input
DLCI will be mapped to an output DLCI at every node. Access DLCIs for
permanent logical links are assigned at subscription time. Trunk DLCIs are
allocated dynamically. The valid value for a DLCI ranges from 16 to 1007
with a default of 16.
Management Type
The Management Interface defines a set of procedures and messages to
manage a PVC and the physical link at the user network interface. Three
management types are used: Local Management Interface (LMI), Annex A,
or Annex D. The management type is determined by the network service
provider at subscription time.
62
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. LMI simply augments the ANSI/CCITT standard Frame Relay
protocol and in no way interferes with the normal operation of user PVCs
on the interface.
Annex D provides additional procedures for permanent virtual connections
using unnumbered information frames. Annex D describes the means for
notification of outage of a permanent virtual connection and recovery from
such a condition. This follows the ANSI T1.617 standards.
Annex A provides additional procedures for permanent virtual connections
using unnumbered information frames. Annex A describes the means for
notification of outage of a permanent virtual connection and recovery from
such a condition. This follows the ITU-T Q.933 standard
Encapsulation Type
The Encapsulation Type depends on the type of device that is connected
at the other end of the trunk. If another MultiFRAD 100 is connected at the
other end of the trunk, then the Mux mode is used. If a non-MultiFRAD 100
is at the other end of the trunk, then the Raw mode is used.
Management Parameters
Polling Interval
The Polling Interval defines a time period in which a status enquiry message
is sent from the MultiFRAD to the network. The Status Enquiry message
requests the status of the PVC(s) or verification of the status of a physical
link. When the Status Enquiry message is sent by the MultiFRAD, the Polling
Interval is restarted. The network responds with a status message that
reports the status of the PVC or verifies the integrity of the physical link. The
polling interval is 5 to 30 seconds with a default of 10 seconds.
63
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. After each full cycle of
the Monitored Event Counter, if the actual number of errors equals or
exceeds the error threshold, the trunk status is brought down and no data
may be sent. The error count is reset at the beginning of each cycle of the
Monitored Event Counter. The Error Threshold Count can range from 1 to
10 with a default of 3 and should be less than or equal to the Monitored Event
Counter.
Monitored Event
The Monitored Event 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
Committed Info Rate (CIR)
The Committed Info Rate (CIR) 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. When the CIR is exceeded, but the data rate
is below the Excess Burst Rate (Be), there is a possibility that data may be
discarded. When the Be is exceeded, data will most likely be discarded.
The default CIR is 32K.
64
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. Back-to-back mode can also
be used to connect two MultiFRADs over a private leased line.
Excess Burst Rate (Be)
The Excess Burst Rate (Be) defines the maximum allowable data transfer
rate the MultiFRAD can exceed the Committed Info Rate (CIR) during a time
interval. The Be is the maximum additional data rate at which the MultiFRAD
can present to the network during a time interval. The default Be is 24K.
65
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.
5.6
Diagnostics
The MultiFRAD Diagnostics dialog box allows you to run two loopback
tests, a memory test, and watch dog test. The Diagnostics dialog box is
displayed by clicking on the Diagnostic button in the MultiFRAD dialog
box.
66
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. If the data port device is an async device, then
the Command Mode switch (DIP-Switch position 1) can be in either position
in order for the data to be looped back to the sending (DTE) device. If the
data port device is a sync device, the Command Mode switch must be in the
up position (Data mode) in order for the device to receive the looped back
data.
The trunk loopback test requires that DIP-Switch position 3 (Loopback Test
Mode) be in the DOWN position in order for the internal DSU to loop back
the data received from the DTE device.
Other Tests
The memory test checks the on-board memory. A warning will be displayed
that "The unit will be reset now and the factory defaults will be restored.
The watch dog test will reset the unit. A "Warning: This watchdog test will
reset the unit. Do you wish to continue?" A brief message will be displayed
stating that the watch dog test passed.

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. If the port is
configured for synchronous operation, refer to Sync Data Port Configuration.
When the port is configured for asynchronous operation, options such
as speed, flow control, and pacing may need to be changed. The

The Async/Sync option configures the port for either asynchronous or
synchronous operation. When an asynchronous device such as a PC or
a host computer is connected to the port, the data port needs to be
configured for asynchronous operation. The default for this option is
Async.
The Speed option needs to be set to match the speed of the async
device. When the data port is connected to an asynchronous device,
the baud rate can range from 300 bps to 57.6K bps. The default port
speed is 57.6K bps.
72
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 default condition is CTS. Flow control is the means by which data
flow from the device into the MultiFRAD is controlled. Flow control is
necessary when the data handling capacity of the data port cannot keep
up with the volume of data sent to it. When the data device controls data
flow to itself, it is called pacing (see Pacing option). The combination of
flow control from the port device and pacing to the data device is how
data transfers are regulated so that no data is lost.

The Enq/Ack Flow Control option 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). The default condition for this option is off.
The Echo option enables data entered on the data device keyboard to
be returned to the device's monitor. The purpose of this option is so that
an operator will not experience undue delays in seeing entered data
appear on their monitor. The default condition for the echo option is off.
The Pacing option controls the data flow to the data device. This option
only applies to the async mode of operation. Pacing is necessary when
the flow of data to a device operating on the data port is more than it can
process. If the device cannot process the volume of data sent to it, then
the pacing option should be turned on. The pacing method used is
determined by the type of flow control. The default condition is for this
option to be turned off.
73
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. This is
done by allowing selected pins (signals) on one MultiFRAD to be
passed through to selected pins on a remote MultiFRAD. The default
condition is for this option to be turned off. The following diagram shows

The Pass Xon option enables the XON/XOFF flow control signals to be
passed on to the data device. This option only applies during the async
mode of operation. 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.
74
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.
When the port is configured for synchronous operation, the following
Data Port Configuration menu displays the default parameters:

The Async/Sync option configures the port for either asynchronous or
synchronous operation. When a synchronous device such as a LAN
bridge or router is connected to the port, the data port needs to be
configured for synchronous operation.
The Speed option needs to be set to match the speed of the sync
device. When the data port is connected to a synchronous device, the
baud rate is from 300 bps up to 128K bps. The default channel speed is
56K bps.
The Idle Condition option must be set to match the idle condition of the
synchronous device connected to the data port. The idle condition
determines 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). The other idle condition is the
mark state (Mark). The transmit LED will be off during idle time if the
synchronous device is in the mark state during idle conditions.
The NRZ/NRZI Encoding option refers to the fact that synchronous data
can be encoded by using either the NRZ (Non-Return to Zero) or NRZI
(Non-Return to Zero Inverted) method. This option must match the
synchronous device’s encoding. The default is NRZ. With NRZ encod75
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.
The CRC Preset option 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.
The Inter-frame Timer option can be changed to make the MultiFRAD
wait a specified length of time between frames being transmitted on the
data port. The user can choose delay times of 2,5,10 and 15 milliseconds. A typical use for this parameter is to simulate transmission delays
encountered with equipment that toggles hardware signals after
transmission of each frame, like PC cards used to connect to legacy
systems. The following options can be specified for the timer: Off, 2mS,
5mS, 10mS, and 15mS. The default is off.

The Access Rate option displays the maximum data rate of the trunk.
The Access Rate determines the speed of the access channel (trunk).
The Access Rate can not be changed.
The RTS (Request-To-Send) Signal Status of Follows input from DTE
enables the DTE to control the carrier on status on the trunk. The RTS
Forced ON option is used in the DSU-only mode when a multi-drop
application is used and is only used by the host unit. The default is
Follows input from DTE.
The Back to Back option 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. Back-to-back mode
can also be used to connect two MultiFRADs over a private leased line.
The DLCI option (Data Link Connection Identifier) is assigned by the frame
relay service provider for the PVC (Permanent Virtual Circuit) that is on your
77
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. When the CIR is exceeded, but the data rate is below the Excess Burst Rate (Be), there is a
possibility that data may be discarded. When the Be is exceeded, data
will most likely be discarded. The default CIR is 32K.
The Excess Burst Rate (Be) option defines the maximum allowable
data transfer rate the MultiFRAD can exceed the Committed Info Rate
(CIR) during a time interval. The Be is the maximum additional data rate
at which the MultiFRAD can present to the network during a time
interval. The default Be is 24K.
The Management Type option defines a set of procedures and messages to manage PVCs and the physical link at the user network
interface. Three management types are used: Local Management
Interface (LMI), Annex A, Annex D. The management type is determined
by the network at subscription time.
The Polling Interval option defines a time period (T391) in which a Status
Enquiry message is sent from the MultiFRAD to the network. The Status
Enquiry message requests the status of the PVC(s) or verification of the
status of a physical link. When the Status Enquiry message is sent by the
MultiFRAD, the Polling Interval is restarted. The network responds with a
status message that reports the status of the PVC or verifies the integrity of
the physical link. The polling interval is 5 to 30 seconds with a default of 10
seconds.
The Full Status Counter option determines how many Polling Intervals take
place before a full status (N391) is sent from the network. A Full Status
Enquiry message is sent from the MultiFRAD to the network requesting
status reports of all the PVCs on the physical link.
The Error Threshold Count option is used to indicate the threshold
number of errors occurring during a full cycle of the Monitored Event
Counter. After each full cycle of the Monitored Event Counter, if the
actual number of errors equals or exceeds the error threshold, the trunk
status is brought down and no data may be sent. The error count is
reset at the beginning of each cycle of the Monitored Event Counter. The
Error Threshold Count can range from 1 to 10 with a default of 3 and
78
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. If another MultiFRAD 100 is
connected at the other end of the trunk, then the Mux mode is used. If a
non-MultiFRAD 100 is at the other end of the trunk, then the Raw mode
is used.

In Async mode, comparing the number of frames transmitted with the
number of retransmits needed to get data over the link can indicate a
line problem. Comparing the data frames received and receive errors
can also indicate a problem with the trunk. Comparative numbers that
80
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.
The Remote Downs entry means that the MultiFRAD has sent data 30
times and could not get it through (the link between the two MultiFRADs
is broken).
The Status Enquiries Transmitted count shows how many enquiries
the MultiFRAD has sent to the network. An enquiry is sent every time
the Polling Interval Timer expires (default of 10 seconds).
There are 4-counts of status messages received from the network.
Status messages are sent by the network in response to the status
enquiries from the MultiFRAD. The sum of the status messages received count and the full status messages received count should equal
the status Enquiry Transmitted count.
The Status Messages Received count indicates the number of KeepAlive status messages the network has sent.
The Full Status Messages Received count indicates the number of Full
Status Messages (messages that include the PVC status - either new or
active) received in response to a status enquiry.
The Async Status Messages Received count indicates the number of
PVC status messages that were received independently, not as a
response to an enquiry from the MultiFRAD.
The Bad Status Messages Received count indicates the number of
status messages received that were bad due to a frame-level error (a
bad CRC or an aborted frame) or a protocol error (due to the wrong
management type, etc.)

6.5.1 Loop Tests
The Loop Tests menu allows for selection of two loopback tests, or
return to the previous menu or to the Main Menu. The Data Port Loopback Test tests the interface between the data device and the MultiFRAD. The Trunk Loopback Test tests can be used both locally and
remotely. When it is used locally, the internal DSU should be set to
82
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.

The Data Port Loopback Test puts the MultiFRAD's data port in
loopback mode. This means that any data that comes into the data port
is immediately looped back out to the user device. Use this test to verify
that the data port cable and its connections are OK, and that the
MultiFRAD's data port settings are correct.
The Trunk Loopback Test is selected when the internal DSU is set for
loopback mode (DIP-Switch 3 is DOWN). This tests the data port
circuitry and the MultiFRAD's trunk circuitry up the DDS line circuit.
The methodology for all of the tests is the same:
1. Put the MultiFRAD (either the local or remote one) into the desired
test mode.
2. Connect the user device to the data port of the local MultiFRAD.
3. Send data from the user device.
4. Verify that the data received from the MultiFRAD matches exactly
what was sent.
5. If the data received is the same as the data sent, then the test
passed. If the data received is corrupted or no data is received,
then the test failed. A failed test indicates a problem either with
the cables, connections, or one of the units involved in the test. If
the cause of the failure is not readily apparent, try using the
process of elimination to isolate the trouble spot(s). The tests are
listed in order of complexity. If the Remote Trunk Loopback fails,
83
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. The watch dog test verifies that the
watch dog circuitry is working.
