Model 3086FR Frame Relay over ATM IAD overview
The Model 3086FR is a G.SHDSL Integrated Access Device that combines high speed IP routing and access
via ATM /PPP. In addition, the Model 3086FR serial port converts FR legacy traffic to ATM traffic using
FRF.5 (Frame Relay/ATM PVC Network Internetworking Implementation) and FRF.8 (Frame Relay/ATM
PVC Service Internetworking Implementation). The Model 3086FR offers direct connection to a
10/100Base-T Ethernet environment, a V.35 or X.21 serial direct connection to a router or FRAD. The
3086FR combines traffic from the Serial and Ethernet ports over a single pair DSL connection.

Model 3086FR ATM IAD User Guide 2 • Product Overview
Product Overview
The Model 3086FR IAD operates as a Frame Relay to ATM converter (via serial port), as a bridge or a router
and has three ports for communication:
• The Ethernet port—Connects to the LAN side of the connection
• The Line port—Provides the G.SHDSL transmission connection between the CPE and CO DSL IAD
• The TDM port—Connects to local device for Frame Relay to ATM conversion and data uplink via the
DSL link
The IAD provides all layers 2 and layer 3 protocols required for end-to-end-link communication.
When configuring the 3086FR, questions must be answered so the 3086FR functions as desired. For example,
when a router or bridge module needs to be activated, some questions would be:
• Is a default gateway required?
• Which encapsulation technique is best for this application: PPPoA, IPoA, or another?
These decisions can be made and implemented more easily if the Model 3086FR’s fundamental architecture is
understood. Also, while configuring the Model 3086FR via a browser using the built-in HTTP server is very
intuitive, an understanding of the architecture is essential when using the command-line interface (CLI) com
mands.
-
The fundamental building blocks comprise a router or bridge, interfaces, and transports. The router and bridge
each have interfaces. A transport provides the path between an interface and an external connection. For exam
ple, the Ethernet transport attaches to an Internet Protocol (IP) interface. A transport consists of layer 2 and
everything below it. Creating a transport and attaching it to a bridge or router’s interface enables data to be
bridged or routed. The supported transports are PPPoA, RFC 1483 (Multiprotocol Encapsulation over ATM
AAL5), and IPoA.
Configuring an interface and transport for the router or bridge requires naming the interface and transport before
attaching them. When using the built-in HTTP server web browser, this is done automatically. But when config
uring the Model 3086FR via CLI commands through the RS-232 control port, it must be done manually.
Model 3086FR IADs can connect over an ATM PVC transport.
The PVC requires the configuration of the virtual path identifier (VPI) and virtual circuit identifier (VCI). The
VPI can be any integer between 0–4095 inclusive. The general rule for the VCI is an integer between 1–65,535
inclusive. Examples in this manual use a VCI of 600 or above. The main restriction in choosing a VCI is that
VCIs below 32 are reserved for such predefined functions as ILMI. The VCI values of 600 and above used in
this manual are also above the range used by many signaling implementations for SVCs.
The HDLC is a packet-based transmission across the DSL Link.
Applications Overview
The Model 3086FR is used in FR over ATM applications connecting FRAD equipment to ATM based
DSLAMs. In addition, the 3086FR is used in the connection of small to medium size enterprise to internet
services (connection to ISP), or connection to remote branches using DSL access using PPP over ATM. In
most applications, the Model 3086 works with Patton’s 3096RC ForeFront System, but it will also connect to
third-party G.SHDSL devices.

Model 3086FR ATM IAD User Guide 2 • Product Overview
FR over ATM
The Model 3086FR primary function is the conversion of legacy ports running FR traffic to ATM. In many
instances, customers have older but functioning equipment, and need to connect to newer technology offer
ings from service providers or telcos. Customers are not ready to make a significant investment in new and
expensive equipment. The Patton model 3086FR fills that gap providing seamless and economical FR to ATM
conversion, allowing customers to keep using their legacy equipment.
Integrated access
In addition to FR to ATM conversion and transport over DSL, the 3086FR is a full feature router allowing
routed or bridged services between the DSL interface and the 10/100Base-T port. The 3086 can simulta
neously transport traffic from the serial port and the 10/100Base-T Ethernet port over a single pair DSL link.
In this case, the 3086FR operates in split mode DSL bandwidth allocating dedicated timeslots in the DSL
frame for the serial port, and for the Ethernet traffic.

Model 3086FR ATM IAD User Guide 4 • Connecting the DSL and data ports
Introduction
The model 3086FR comes with a DSL port, 2 data ports: serial (V.35, X.21, or T1/E1), and a 10/100Base-T
Ethernet port. Frame Relay data from the serial port is passed to the FR to ATM converter engine and is prepared
for transmission over the DSL link – data from or to the serial port does not enter the router core of the 3086FR.
Data from the Ethernet port is processed by the router or bridge core before entering the ATM encapsulation layer.
The 3086FR can be used as FR to ATM converter (ATM transport over DSL). In this case, configuration of
the unit involves the following steps:
• Configure the DSL interface (assigning all bandwidth to the serial port).
• Configure the serial port
• Configure the FR to ATM conversion
When the 3086FR Ethernet port is used to route data from and to the Ethernet port, the following steps are
required to configure the unit:
• Configure the DSL interface (assign bandwidth required to the serial port, the 3086FR will assign the
remaining bandwidth to the Ethernet port)
• Configure the serial port
• Configure the FR to ATM conversion
• Configure the WAN link layer 2 ( ATM)
DSL port
The DSL port (see figure 6) is located on the back of the unit, and is presented on an RJ-11 female jack. The
interface has a nominal impedance of 135-ohms. The Model 3086FR supports DSL communication between
a customer location and a central office from 192kbps to 2.3 Mbps.

Model 3086FR ATM IAD User Guide 4 • Connecting the DSL and data ports
To function properly, the Model 3086FR needs one twisted pair of metallic wire. This twisted pair must be
unconditioned, dry, metallic wire, between 19 (.9mm) and 26 AWG (.4mm) (the higher number gauges will
limit distance). Standard dial-up telephone circuits, or leased circuits that run through signal equalization
equipment, or standard, flat modular telephone type cable, are not acceptable. The female RJ-11 connector on
the Model 3086FR’s twisted pair interface is polarity insensitive and is wired for a two-wire interface.
Figure 7. RJ-11 pinout
TDM Port
Model 3086FR units enable V.35, X.21, or T1/E1 interface connection to local routers, multiplexers, and other
Frame Relay devices. The V.35 interface is presented either on a M/34, or DB-25 female connectors. The X.21
interface is presented on a female DB-15 connector, while the T1/E1 interface is presented on an RJ-48C jack,
additionally the E1 interface is presented on dual BNC.

V.35 and X.21 ports
The serial port in the 3086FR is simple to configure. The V.35 interface is wired as a DCE, the X.21 interface
can be configured as a DCE (factory default), or as a DTE via internal configuration jumper. The following
sections describe the 3086FR X.21 and V.35 port connection to DTE and DCE devices.
Connecting the 3086FR serial port to a DTE
The serial port on the Model 3086FR is configured as a DCE so it connects directly to a DTE using a standard
straight through cable. The cable should present either a male M/34 or DB-25 connector on one end, for V.35
interfaces, or a male DB-15 for X.21 interface connection. The other end should be terminated with the appro
priate connector ( check your DTE equipment manual for pinout, gender, and DTE/DCE port configuration).
Connecting the 3086FR serial port to a DCE
V.35 interfaces.
The V.35 interface in the 3086FR is wired as a DCE, no DTE configuration is possible. If the equipment that
the 3086FR is connecting to locally does not have the option for DTE configuration, a tail-circuit cable will be
required (this cable is available from most datacomm supply vendors). The tail-circuit cable will cross most
interface signals, so that the DCE interface of the 3086FR and the DCE interface of the third party equipment
can function properly. Please be aware that some third party equipment will not be able to work properly in
DCE to DCE configurations even when using a tail circuit cable (please refer to your third party equipment
user manual for information on DCE-to DCE operation). The 3086FR requires a cable with a male M/34 or
male DB-25 connector.
-
X.21 interfaces.
The Model 3086FR’s X.21 interface configuration can be modified, by the user, as DCE (factory default) or
DTE, via an internal jumper board. When the local third party equipment is configured as DCE, the Model
3086FR X.21 serial port can be configured as DTE, and a regular straight through cable can then be used. Do
the following to configure the X.21 port as a DTE:
1. Open the 3086FR’s case by inserting a screwdriver into the slots and twist the screwdriver head slightly.
The top half of the case will separate from the lower half of the case (see
Figure 9). Take caution not to
damage any of the PC board mounted components.

2. Locate the small daughter board on the 3086FR board between the DSL port (RJ-45) connector and the
serial port connector (
Figure 10 shows location of DTE/DCE daughter board).
Figure 10. Location of DCE/DTE board
3. The DTE/DCE daughter board is installed at the factory with the DCE label and arrows pointing towards
the X.21 connector (DCE configuration). To change to DTE configuration, lift the daughter board from
the connector, turn it around so that the DTE label an arrows point to the X.21 connector, and place it
back on the connector. The X.21 port is now configured as a DTE.
Note
When the X.21 port is configured as a DTE, the clocking mode for the port
must be set for external clock.

T1 Interface
The 3086FR enables T1 or E1 device located at customer locations to access a carrier’s network over two wire,
long reach DSL links. This capability allows providers to offer T1/E1 services at customer locations that were
previously outside the reach of standard T1/E1 lines.
The 3086FR/K offers a user configurable T1 or E1 interface. Selection of the interface is done via DIP
switches, HTTP/SNMP, or command line interface (CLI).
The T1 interface is an eight position keyed modular jack configured as a RJ-48C for connection to 100-ohm
twisted pair lines.
Figure 11. 3086FR T1 port pinout
T1 Interface Connection
The 3086FR will usually connect either to a local T1 device, or to a Telco terminated T1 line jack.
• To connect the 3086FR’s T1 port to a local T1 device ( PBX, router, mux) use a T1 ‘crossover’ twisted pair
cable. A crossover cable connects the transmit pins of the Model 3086FR’s T1 port to the receive pins of the
device attached to this port and vice versa. Check the third party T1 equipment documentation for pinout
information and cable requirements.
• To connect the 3086FR’s T1 port to a Telco terminated T1 line jack, use a straight through twisted pair
patch cable. Consult with your T1 service provider for exact pinout information and cable requirements.
T1 Interface Configuration
The 3086FR T1 interface can be configured via HTTP/SNMP, or command line interface (CLI). This section
discusses HTTP (web server) configuration. For CLI, see Appendix D,
“Command Line Interface (CLI) Oper-
ation” on page 165.
Web Interface Configuration
The T1 interface page is accesed from the Main Menu > E1/T1. This page allows configuration of T1
paraemeters as follows:

ally, save the configuration by going to the Configuration > Save Config menu.
E1 Interface
The 3086FR enables T1 or E1 device located at customer locations to access a carrier’s network over two wire,
long reach DSL links. This capability allows providers to offer T1/E1 services at customer locations that were
previously outside the reach of standard T1/E1 lines.
The 3086FR offers a user configurable T1 or E1 interface. Selection of the interface is done via HTTP/SNMP
or command line interface (CLI).
The E1 interface is presented on both a modular, 8-pin RJ-48C jack for connection to 120-ohm twisted pair
lines, and dual BNC female connectors for connection to 75-ohm coaxial lines.

Figure 12. E1 interface with RJ-48C jack (120–ohm) and dual BNC (75-ohm) connectors
E1 Interface Connection
The 3086FR will usually connect either to a local E1 device, or to a Telco terminated E1 line jack.
• To connect to the 3086FR E1 port and a local E1 device, use an E1 crossover twisted-pair cable. A crossover
cable connects the transmit pins of the Model 3086FR’s E1 port to the receive pins of the device attached to
this port and vice versa. Check the third party E1 equipment documentation for pinout information and
cable requirements. If the E1 connection is made via the BNC connectors, connect the TX BNC of the
3086FR to Recive (RX) BNC of the local E1 device, and vice versa.
• To connect the 3086FR’s E1 port to a Telco terminated E1 line jack, use a straight through twisted pair
patch cable. Consult with your E1 service provider for exact pinout information and cable requirements.
The 3086FR T1/E1 port can be configured via HTTP/SNMP or command line interface (CLI). This section
discusses HTTP (web server) configuration, for CLI and SNMP information see
Appendix E on page 165.

and password ‘superuser’. From the main page click on the E1/T1 option > Configuration. This page allows
configuration of E1 parameters as follows:
Time Slot Select. For unframed E1 service (Clear Channel) enter time slots 0-31. For a full framed E1 enter 131, for partially filled E1 enter the range of timeslots using the format for example: 1,2,3,5; or 1-5,10-31. Any
entry for timeslots above 31 will return and invalid selection message.
Line Options: Choose from Clear Channel E1, Fractional E1, Fractional E1, Multi-Frame(CAS) E1, MultiFrame(CAS) E1 with CRC. Consult with your service provider which option is required.
Line Code: Choose from AMI or HDB3. Most E1 applications use HDB3
Line Build Out: Select 120 ohm if the E1 connection is made via the RJ-48C connector, select 75 Ohm if the
E1 connection is made via the Dual BNC connectors.
FDL Mode: FDL is a T1 application, therefore select ‘Fdl- none’ for E1 applications.
Idle code: Options are Enabled or Disabled. When idle code is Enabled, the 3086FR/K inserts idle codes on
E1unused timeslots. Set this option to ‘Disabled’ unless instructed otherwise.
Power Down: Options are Normal and Powerdown. When the 3086FR is set to powered down, it will set the
E1 interface pins to high impedance to protect the device – set unit to “Normal” for regular operation.
Once all options have been selected, click on the

Introduction 46
Page 47
Model 3086FR ATM IAD User Guide 5 • Configuring the DSL and serial ports
Intended DSL Data Rate
DSL line rate at which you wish to connect. In a CPE to DSLAM configuration, the 3086FR (CPE) will
have the DSL rate dictated by the DSLAM (CO). The model 3086FR will connect at nx64kbps speeds from
192kbps to 2.3Mbps.
Actual DSL Rate
This field displays the DSL rate connection; it displays the payload rate plus 8kbps automatically assigned to a
DSL management channel. For instance, if a DSL rate of 512kbps is selected in the “Intended DSL Data Rate”
window, the actual DSL Data rate field will display 520kbps, this corresponds to 512kbps payload plus 8kbps
management channel.
DSL Rate
Number of i Bit: The i bit increments DSL speed by 8kbps in addition to the DSL rate selected in the
“Intended DSL Data Rate” window. Most applications use nx64kbps DSL speeds, leave this setting at “0”,
unless your application calls for a non-nx64 speed. Selections for the I bit are 0 through 7 as follows:
0 = no increment
1 = Intended DSL data rate + 8 kbps
2 = Intended DSL data rate + 16 kbps
3 = Intended DSL data rate + 24 kbps
4 = Intended DSL data rate + 32 kbps
5 = Intended DSL data rate + 40 kbps
6 = Intended DSL data rate + 48 kbps
7 = Intended DSL data rate + 56 kbps
Terminal Type
Select between Remote and Central. Use the “Remote” setting for 3086s located at customer premises and
which connect to a DSLAM.
Note
The unit set to “Central” will act as master and will impose DSL rate on the
unit set as “Remote”
Interface Type
The 3086FR is set to ATM transport.
Test Modes
The 3086 use a series of loopbacks to test the serial, Ethernet, and DSL links, please refer to the Diagnostics
section for more information.
Annex Type
Annex type refers to spectral compatibility between DSL and T1 or E1 signals. For North America and other
areas where T1 lines are used, select Annex A, for areas where E1 lines are used select Annex B.

Line Probe
Line probe is a tool used to determine maximum achievable rate when initially connecting 3086 to a copper
line of unknown quality. Set this feature to “Enable” on both 3086s at each end of the link.
Note
Once line probe measurements have been completed set this feature to
“Disabled”
The bottom four fields in the G.SHDSL Attributes page correspond to error monitors. Error monitor will
watch the DSL line parameters and determine whether or not the current DSL link is capable of passing error
free data. The error monitor will accumulate DSL line statistics (CRC count, FIFO errors, LOSW count,
etc..) and make a determination on whether or not to drop DSL link and retrain based on the thresholds setup
by the user
• Error Monitor Max Interval Errors: Number of allowable errors per interval. Default = 3
• Error Monitor Interval Time (sec): Length in seconds of the current interval. Default = 1
• Error Monitor Interval Count: Number of intervals in error before the DSL link is restarted. Default = 3
• Error Monitor Start Up Delay: Amount of time to wait, after the link is up, before monitoring the DSL
link. Default = 5
Once you have entered your selections or changes, click on the “Configure” button at the bottom of the screen.
Additional go to the G.SHDSL > Action link on the left side of the screen, and hit “action” to start the DSL
interface with the new settings.

Model 3096RC G.SHDSL T-DAC Administrators’ Reference Guide 6 • Configuring FR and ATM features
Introduction
This chapter explains the three basic Frame Relay (FR)/ATM configurations of the 3086FR IAD and how to
configure them. They are:
• Frame Relay Network (FRN) interworking (FRF.5)
• Frame Relay Service (FRS) interworking (FRF.8)
• Ethernet-based Frame Relay/ATM operation
FRF.5 and FRF.8 are two agreements between the FR Forum and ATM Forum that enable FR and ATM networks to be used together; along with the Ethernet-based Frame Relay operation configuration, the three ports
may be configured as Ethernet, FR/PPP and ATM with the ability to route between these three ports. Consult
the specific sections for each type of application.
Frame Relay Network (FRN) Interworking (FRF.5) provides a mapping and encapsulation mechanism
between FR and ATM networks so an ATM network may be used to transport FR from end-to-end. The ATM
network is completely transparent to the FR network and equipment. The IWF (Interworking Function
equipment) implements this function; in this case, done by the Model 3086FR.
If transport speeds higher than the typical FR network are desired or if only an ATM network is available for
transport between two locations running FR, FRF.5 provides the capability for joining these two types of net
works together. Obviously there are significant differences between FR and ATM networks. FR uses variablelength frames while ATM uses a fixed-length cells (53 octets). They also have different parameters and variables
in their headers and trailers.
but uses an ATM network for transport. The IWF is equipment which implements the Interworking Function,
which in this case is FRF.5. The IWF is the Model 3086FR IAD.
Figure 13 is a typical application in which both end locations have FR equipment

Figure 14 is a variation upon the previously described application. Here one end has FR equipment but the
other location has special ATM equipment which recognizes FR. Specifically it must support the FR Service
Specific Convergence Sublayer (FR-SSCS).
Figure 14. Application with one location having FR equipment and the other ATM
equipment
that recognizes FR
One advantage of using FRF.5 over FRF.8 is that one VCC (and one VCI/VPI within the VCC) in the ATM
network is used to transport multiple DLCIs (PVCs) between two FR locations. For additional details, see sec
tion “Frame Relay Network (FRN) Interworking (FRF.5)” on page 57.
With Frame Relay Service (FRS) Interworking (FRF.8), ATM CPE equipment on one end may operate with
FR CPE equipment on the other end. The FRS IWF occurs between the ATM and FR networks and/or equip
ment. FRF.8 provides a conversion mechanism so FR and ATM networks may function seamlessly. Neither
network has no knowledge of the other. It is essentially a complete conversion of the parameters between
Frame Relay and ATM. For additional details, see section
“Frame Relay Service Interworking (FRF.8)” on
page 66.
Figure 15 shows the service interworking between FR and ATM services.

Service interworking between FR and ATM services
Page 57
Model 3096RC G.SHDSL T-DAC Administrators’ Reference Guide 6 • Configuring FR and ATM features
Observe from the stack that a true conversion has occurred between the FR and ATM networks. In FRF.5 the
uppermost sublayer is FR-SSCS, but in the FRF.8 Interworking Agreement, it is null SSCS.
The third application is called Ethernet-based Frame Relay/ATM. While FRF.5 and FRF.8 has a fixed mapping of DLCI PVCs to ATM VCI/VPIs, with Ethernet-based FR/ATM there is not a fixed mapping from FR
to ATM. We now have the ability to do routing between any of the three ports—Ethernet, serial (PPP or FR),
and DSL (ATM) ports. Nevertheless FRF.5/FRF.8 may operate simultaneously. An example of Ethernet-based
FR/ATM is a 3086FR in a company’s office. All three ports are connected through the integrated router. The
serial port (PPP or FR) with the WAN connection (ATM) via the DSL port. See
figure 16. For additional
details, see section “Frame Relay (Ethernet-based) operations” on page 74.
Figure 16.
Example Ethernet-based FR/ATM application
The PCs on the private side of the firewall have access to the web server in the DMZ and the Internet. Outside
users have access to the web server in the DMZ but cannot access the PCs on the company’s private network
(intranet) unless first accessed by one of the company’s PCs behind the firewall.
Frame Relay Network (FRN) Interworking (FRF.5)
Frame Relay Networking (FRN) Interworking (FRF.5) is a mapping and encapsulation mechanism by which
Frame Relay networks can communicate with ATM networks for transporting Frame Relay traffic. As
described in the introduction to this chapter, there are two scenarios. One characteristic of FRF.5—as opposed
to FRF.8—is the necesity to support the Frame Relay Service Specific Convergence Sublayer (FR-SSCS). The
Model 3086FR in FRF.5 mode supports all of the required Interworking Functions (IWF) required for Frame
Relay Network Interworking operation.
The Frame Relay Network Interworking functions are defined by the Frame Relay Forum specification Frame
Relay/ATM PVC Network Interworking Implementation Agreement FRF.5.

FRN configuration options
The Frame Relay Network Interworking functions on the Patton Electronics Model 3086FR are defined by
ports and channels. It is important to understand the implementation of FRF.5 in the Model 3086FR. There
are 8 ATM Ports (called VCC or channel in FRF.5). Each port can be configured to have one channel (DLCI)
or up to 8 channels (DCLIs). The Mux Mode variable controls the selection of one-to-one or many-to-one mul
tiplexing. When the connection multiplexing is configured for one-to-one, each port can carry one channel
(DLCI or PVC). However when many-to-one is selected, up to 8 channels (DLCIs) can be carried in one ATM
port. Since each of the 8 ports may be configured to have 8 channels, up to 64 channels (DLCIs) can be trans
ported over the ATM network. Figure 17 shows the organization of the ports and channels with the associated
variables in the Model 3086FR.

referenced to the ATM link. Thus Tx Data is data that is received on the Frame Relay link and transmitted out
the ATM Link.
Figure 21. Channel Level Packet Information window
FRN configuration options
The Frame Relay Network Interworking functions on the Patton Model 3086FR are defined by CHANNELS
and VPI/VCI. Ports are used to define the lower level Interworking Functions. First a port must be created that
defines such items as the ATM VPI/VCI and the type of mapping that will be used to make the connection.
Once the port is created, channels can be attached to the ports that will allow data channels to pass from the
Frame Relay interface to the ATM interface. Channel configuration variables options include the Frame Relay
DLCI that will be used to communicate with the Frame Relay Network.
Port Level Configuration Options:
Ports are used to define the lower level Interworking Functions. The port configuration defines the following
variables:
• VPI—Virtual Path Identifier: ATM side Virtual Path Identifier for the specified connection.
• VCI—Virtual Channel Identifier: ATM side Virtual Channel Identifier for the specified connection
• DE Mapping—The DE Mapping variable is used to determine how the Frame Relay DE field (Discard Eli-
gibility) will be mapped to the ATM CLPI (Cell Loss Priority Indication). This variable is only used in the
Frame Relay to ATM mapping direction. Note that the DE bit from the core Q.922 (Frame Relay) packet
will always be copied unchanged into the FR-SSCS PDU header cell. The following options define how the
DE will be mapped to the ATM CLPI bit:
- Always_zero: All ATM cells will have the CLPI field set to a constant value of 0.
- Always_one: ATM: All ATM cells will have the CLPI field set to a constant value of 1.

- Convert: The system will convert the DE field received from the Frame Relay packet into the CLPI field
of the outgoing ATM cell that is generated by the segmentation process.
• CLPI Mapping: The CLPI Mapping variable is used to determine how the ATM CLPI (Cell Loss Priority
Indication) bit in the ATM cell will be mapped to the DE (Discard Eligibility) bit of the resulting Frame
Relay packet. There are two options available.
- Fr_sscs_only: The FR-SSCS removed from the ATM header PDU is used to set the DE bit in the out-put
Frame Relay packet. The CLPI bit from the ATM cell is ignored.
- Fr_sscs_and_clpi: Both the DE bit from the ATM header PDU and the CLPI bit from the received ATM
cells are used to determine the output state of the resulting Frame Relay packet. The following table
defines how.

• Multiplexing Mode: The MuxMode variable allows multiple channels to be multiplexed onto a single port.
A port is defined by its’ VPI/VCI of the ATM rfc1483 data path. Channels are defined by their Frame Relay
DLCI. Thus, the multiplexing mode will allow multiple Frame Relay channels to be transported over a single ATM VPI/VCI link. There are two options available.
– Mux_many_to_one: The “many to one” option allows multiple DLCI channels to be transported over a
single ATM rfc1483 connection. Note that if the MuxMode is not set to “many to one” trying to add
multiple DLCI connections will result in errors.
– Mux_one_to_one: The “one to one” option notifies the system that there will be a one to one mapping
between a single ATM port VPI/VCI and a single Frame Relay DLCI.
• FRN Name: Allows the user to name the FRN port. This is helpful when viewing multiple connections to
determine which VPI/VCI is associated with each port.
• FRS state: The state variable allows the user to enable or disable the port for operation. Note that port level
configuration variables are not changeable “on the fly”. If it is required that configuration changes are
required, the user should disable the port, make the configuration changes, and then re-enable the port.
• Port Level Maintenance: Port level maintenance creates an LMI session across the ATM link. This is useful
to determine the status of the link. There are three options available for Port Level Maintenance. The
description of these variables is identical to that described in the beginning of this document. Note that in
each case the only option available is “both”. This means that the system is performing both “Network” and
“User” side LMI functions.
– 933A_both
– 617D_both
– LMI_both
• Port Level Mgt State: This variable defines the state of the Port Level Maintenance.
- Mgt_Port_DOWN: Currently the LMI on the DTE side is DOWN
62 Frame Relay Network (FRN) Interworking (FRF.5)
Page 63
Model 3096RC G.SHDSL T-DAC Administrators’ Reference Guide 6 • Configuring FR and ATM features
– Mgt_Port_UP: Currently the LMI on the DTE side is UP
Channel Level Configuration Options
The Channel Level Configuration variables are used to define the channels that are attached to the ATM port.
The following variables are used to define each channel configuration.
• DLCI—Data Link Connection Identifier: Frame Relay side DLCI for the associated channel.
• FRN Channel Name: Allows the user to name the FRN channel. This is helpful when viewing multiple
channel connections to determine which DLCI is associated with each channel.
• FRN Channel State: The state variable allows the user to enable or disable the channel for operation. Note
that the port that the channel is connected to must be enabled before the channel can be enabled for operation.
• Network DLCI: The network DLCI allows the system to transport data over the atm link using a different
DLCI than is used on the DTE side. If the network DLCI is set to “0”, then the DTE side DLCI will be
used. If the Network DLCI is set to any other value, that value will be used to transport data across the link
using the FR-SSCS.
• Mgt State: The Mgt State variables defines the state of the Channel using the Port Level Management infor-
mation. The following options are available
- N/A: The port associated with this channel is disabled.
- n/a: There is no Port Level Management function enabled for the port associated with this channel.
- Down: The Port Level Management is currently in the “down” state.
- active-congested: The Port Level Management is reporting that this channel is active and it has detected
that the channel is congested.
- Active: The Port Level Management is reporting that this channel is active
- Deleted: The Port Level Management is reporting that this channel has been deleted. This could also
result if the associated channel at the remote end is not configured
- not active: No information has been received from the management port related to this channel

Configuration Management of the Channel Level Variables
The following information can be used to configure the Channel Level information associated with the FRN
connections. The CLI uses the frn directive of the CLI interface for Channel Level configuration.
Note
The frn show port and frn list commands already discussed at the port level
are also useful to gain detailed and overview information about the channels.
Understanding the Channel Level View
The Model 3086FR supports up to 8 individual FRN ports. Each port can support up to 8 channels while set
to the “many to one” multiplexing mode. To access the port level information the user must first define the

Frame Relay Service Interworking (FRF.8)
FRF.8 is a conversion mechanism by which Frame Relay networks can communicate directly with ATM-based
networks. Neither the ATM nor the Frame Relay networks require any understanding of the other network
protocols involved. This conversion is performed within the Model 3086FR’s IWF at the transport service
level. Frame Relay Service Interworking functions are defined by the Frame Relay Forum specification Frame
Relay/ATM PVC Service Interworking Implementation Agreement FRF.8.1.

Page 67
Model 3096RC G.SHDSL T-DAC Administrators’ Reference Guide 6 • Configuring FR and ATM features
FRS Configuration Options
The Model 3086FR supports 64 FRF.8 connections (divided into 8 groups of 8 channels each). The IWF are
configured by group and channel. The group level configuration options are applied to eight channels that are
related to that group. The following list of variables are configured at the group level.
Figure 22. FRS Configuration—Top Level Configuration Menu
Once FRS Setup (FRF.8) is selected (see figure 18 on page 59), the
tion
screen is displayed (see figure 22). The screen gives an overview of the FRS connections that are available.

Translation Mode
The Translation Mode variable defines the encapsulation mechanism that will be required to convert the ATM cells
(encapsulated per RFC2684) to the Frame Relay packets (encapsulated per RFC1490) and back. This is required
because ATM and Frame Relay encapsulate packets in different formats as defined by their respective RFC. There
are two options available for the Translation Mode setting within the Model 3086FR as defined below:
• Translate: When the connection channel is set to translate, the IWF converts between Frame Relay encap-
sulated frame and the ATM encapsulated cells. This conversion is performed by inspecting each frame/cell
and determining the PID (Protocol Identification) field within the packet. (Using this information, the
frame/cell is routed through an encapsulation conversion utility that creates the encapsulation required for
the destination network.) The Model 3086FR supports all 22 protocol types as defined by the FRF.8.1
68 Frame Relay Service Interworking (FRF.8)
Page 69
Model 3096RC G.SHDSL T-DAC Administrators’ Reference Guide 6 • Configuring FR and ATM features
specification. See figure 24 for the encapsulation types and includes an example where a Routed IP packet is
received on both the Frame Relay and ATM sides of the connection. When the packet is received is checked
against the known PID fields, and then the packet is routed to the appropriate encapsulation conversion
station before being sent out the opposite interface.
Figure 24. FRS encapsulation conversion using Translate Mode
• Transparent: The second translation mode option is to set the protocol value to transparent. Transparent is
used when the Protocol being used is not one of the 22 predefined encapsulation types, such as is the case
for voice based systems. When the translation mode is set to transparent, the packet data will be transparently passed from one network to the other without any encapsulation conversions.

DE Mapping
The DE Mapping variable is used to determine how the Frame Relay DE field (Discard Eligi-bility) will be
mapped to the ATM CLPI (Cell Loss Priority Indication) and vise versa. The following options are available:
• Always_zero:
- Frame Relay: All Frame Relay packets will have the DE field in the header set to a constant value of 0.
- ATM: All ATM cells will have the CLPI field set to a constant value of 0.
• Always_one:
- Frame Relay: All Frame Relay packets will have the DE field in the header set to a constant value of 1.
- ATM: All ATM cells will have the CLPI field set to a constant value of 1.
• Convert:
- Frame Relay to ATM Direction: The system will convert the DE field received from the Frame Relay
packet into the CLPI field of the outgoing ATM cell.
- ATM to Frame Relay Direction: The system will convert the CLPI bit received from the ATM cells into
the DE field of the outgoing Frame Relay packet.
FECN Mapping
The FECN Mapping variable is used to determine how the Frame Relay FECN (Forward Explicit Congestion
Notification) bit will be mapped to the ATM EFCI (Explicit Forward Congestion Indica-tion) bit and vise
versa. The following options are available:
• Always_zero:
- Frame Relay: All Frame Relay packets will have the FECN bit in the header set to a constant value of 0.
- ATM: All ATM cells will have the EFCI bit set to a constant value of 0.
• Always_one:
- Frame Relay: All Frame Relay packets will have the FECN bit in the header set to a constant value of 1.
- ATM: All ATM cells will have the EFCI bit set to a constant value of 1.
• Convert:
- Frame Relay to ATM Direction: The system will convert the FECN bit received from the Frame Relay
packet into the EFCI bit of the outgoing ATM cell.
- ATM to Frame Relay Direction: The system will convert the EFCI bit received from the ATM cells into
the FECN bit of the outgoing Frame Relay packet.
FRS Name
Allows the user to name the FRS channel. This is helpful when viewing multiple connections to determine
which DLCI/VPI/VCI combination is associated with each channel.
• FRS state: The state variable allows the user to enable or disable the channel for operation.
The Frame Relay Service Interworking functions on the Patton Electronics Model 3086FR are also defined
as sixty-four channels. Each channel creates a connection between a single DLCI on the Frame Relay net

work and a VPI/VCI on the ATM network. The following configuration options are available for each
channel in the system.
• VPI—Virtual Path Identifier: ATM side Virtual Path Identifier for the specified connection.
• VCI—Virtual Channel Identifier: ATM side Virtual Channel Identifier for the specified connection
• DLCI—Data Link Connection Identifier: Frame Relay side DLCI for the specified connection
CLI Configuration Method
The following section describes how to configure FRS channel connections using the CLI interface.
The system is made up of eight groups and 64 channels. The group configuration variables apply to all eight
channels within that group. Each channel is configured independently and will all run over as single LMI session or with no LMI running. The FRS (FRF.8) connections are configured using the “frs” directive in the CLI
interface. The following commands are available:
Show one of the eight groups
Command: frs show group #
The frs show group # command shows the configuration of te group defined by the # directive. Possible

Frame Relay (Ethernet-based) operations
Ethernet-based (or basic) Frame Relay is also available within the Model 3086FR. This Frame Relay service can
be used in a similar fashion to other Ethernet-based transports within the system such as PPP or the Ethernet
transport. Multiple Frame Relay transports, with different DLCI numbers, can be built upon the HDLC con
troller that is available with the 3086FR. The Frame Relay Interface is available at the serial interface for transport out of the Ethernet Interface or the ATM link.
Frame Relay Configuration Options
The Frame Relay transport is configurable from both the CLI and the web interface. The following configurable variables are available through both interfaces.
Channel Segment Size
The channel segment size is used to define fragmentation of the packets based on the Frame Relay Forum IA
FRF.12. If this variable is set to 0 then FRF.12 “Frame Relay Fragmentation” will be disabled. If set to any
other value it will set the fragmentation size used.
DLCI: Data Link Connection Identifier

Model 3086FR ATM IAD User Guide 8 • 3086FR routed and bridged ATM connections
Introduction
In addition to FR to ATM conversion and transport over DSL, the 3086FR is a full feature ATM router,
allowing routed or bridged services between the DSL interface and the 10/100Base-T. The Model 3086FR can
simultaneously transport traffic from the serial port and the 10/100Base-T Ethernet port over a single-pair
DSL link. In this case, the 3086FR operates in split-mode DSL bandwidth allocating dedicated timeslots in
the DSL frame for the serial port, and for the Ethernet traffic.
When routing or bridging data from the 10/100Base-T port, keep in mind that data from the 3086FR serial
port is converted from Frame Relay to ATM encapsulation only, this traffic does not go thru the router or
bridge core in the 3086FR. When enabling the router or bridge for traffic from the 10/100Base-T, a separate
PVC and dedicated DSL timeslots have to be configured for this traffic.
The main configuration steps for this scenario are as follows:
1. Configure the DSL interface. Assign DSL bandwidth to the serial port, and the remaining DSL bandwidth
will be assigned to 10/100Base-T port. For instance, if you select a DSL rate of 512 kbps and 256
assigned to the serial port, the remaining 256 kbps of DSL bandwidth will be automatically assigned to
10/100Base-T traffic.
2. Configure the serial port. Assign the DSL bandwidth required for the traffic on this port.
3. Configure the FR to ATM features for the serial port.
kbps are
4. Configure the LMI
If you are using the 10/100Base-T port to route or bridge data:
1. Create a bridged or routed ATM connection.
2. Configure the bridge or router, and ATM parameters (including a PVC)
3. Configure DHCP, NAT, Authentication, Security features, etc, if needed, for this routed or bridged con-
nection.
The following ATM routed and bridged connections are available with the 3086FR:
• RFC 1483 bridged
• PPPoA (PPP over ATM) bridged
• RFC 1483 routed
• IPoA (IP over ATM) routed
• PPPoA (PPP over ATM) routed

RFC 1483 Bridged Configuration.
No additional IP addresses are needed other than the IP address chosen earlier. In fact, if you are configuring and
managing the model 3086FR only from the CLI (Command Line Interface), an IP address is not needed at all.
The limitation of no IP address precludes the user from doing web management of the 3086FR since manage
-
ment is done via the Ethernet port.
As in the PPPoA Bridged application, both sides of the RFC 1483 bridged connection are on the same subnet.

PPPoA Routed (RFC 2364)
This routed application is very similar to the PPPoA Bridged application. The user data for transmission is in
the form of IP packets but encapsulated in a PPP packet, transmitted and received through a PPP session to the
connection. The PPP packets are encapsulated according to RFC 2364 for transmission over the ATM link.
The packets are de-encapsulated on the receive side so that the IP data can be delivered to the end user.
The Central (Model 3086FR) end functions as a local ISP which will authenticate the Remote user (Model
3086FR). The CPE side, with Remote and 3086FR-A, may represent a home PC which is connecting to a cen
tralized PPP server (Local and 3086FR—B).
Since this is a routed application, there are differences to be noted. Referring to the application diagram, three
unique subnets exist. The Ethernet LAN on the 3086FR and Remote side, the Ethernet LAN on the 3086FR
and Central side, and lastly, the subnet of the ATM’s PVC link between the two modems, 3086FR-A and
3086FR-B. The 3086FR-B and Local end (the Central side) may also be a DSLAM.
