Notice: The Canadian Industry and Science Canada label identifies certified
equipment. This certification means that the equipment meets certain telecom-
munications network protective, operational, and safety requirements. The
Department does not guarantee the equipment will operate to the user's satisfac-
tion.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equip-
ment must also be installed using an acceptable method of connection. In some
cases, the company's inside wiring associated with a single line individual
service may be extended by means of a certified connector assembly (telephone
extension cord). 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 telecom-
munications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connec-
tions 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.
Users should not attempt to make such connections themselves, but

Introduction
UN DERSTAN DIN G FRAME RELAY
Frame relay is a wide area network (WAN) service designed to
minimize physical connections. This is accomplished by using
virtual connections within the frame relay cloud and accessing
these virtual circuits with normally one physical connection at
each location to the frame relay service. Virtual circuits are
addressed using header information at the beginning of each
frame. These frames are formatted by the user's CPE equipment
such as the ADTRAN FSU.
ANSI standards describe how each frame must be constructed to
provide interoperability between CPE equipment and frame
relay switching equipment. Each frame must contain a header,
at least one byte of information data, two bytes of CRC16, and a
trailing flag 0x7E.
This header information contains a virtual circuit address known
as a DLCI (data link connection identifier). The header informa-
tion also contains bits used for network congestion control.
Frame relay virtual circuits may be defined as permanent (PVC)
or switched (SVC). PVCs have the same DLCI for a given path
each time a user protocol session is established. The network
service provider assigns these DLCIs at subscription time. SVCs,
on the other hand, have DLCIs dynamically assigned each time a
user protocol session is established. The CPE equipment must
request a call and the DLCI is assigned by the network switching

Chapter 1. Introduction
equipment. This DLCI is valid until the call is disconnected and
may be assigned a different value each time a call is requested.
PRO DUCT O VERVIEW
The FSU provides a low cost solution for the CPE equipment in a
private or public frame relay network. The FSU connects to the
frame relay network via 56/ 64k DDS (digital data service) or
T1/ FT1 access links. Connections to 56/ 64k DDS are made
using an integral 56/ 64k DSU or an external DSU. T1/ FT1
connections are made using an external T1 DSU/ CSU through a
V.35 interface.
The FSU provides connections to the user equipment through
two independent ports emulating a DCE device. These ports can
be configured for either RS-232 or V.35 signal specifications.
Synchronous protocol speeds up to 512 kbps and asynchronous
protocol speeds up to 38.4 kbps are supported.
The FSU handles each frame of the user data in a three-step
manner. The first step is terminating the user protocol. The
layer at which this termination occurs varies depending on the
user protocol selection for a given port. The next step is examin-
ing the user protocol destination address and routing to the
destination port and virtual circuit. The last step involves
encapsulating the information field of each frame and re-
encapsulating based on the destination port configuration. A
similar process is used for frame relay frames received on the
network port.
The major features of the FSU are as follows:
• Two DTE (data terminal equipment) ports for use on a single
frame relay network interface.
• Support for IP (internet protocol), SDLC (synchronous data
link control), Bisync, SLIP (serial link IP), PPP (point-to-point
protocol) both sync and async, frame relay, BOP (bit-oriented
protocol), and async protocols.
• SNMP (simple network management protocol) management
capability provided inband with support for RFC 1315 (frame

MIB.
• DCE port supporting rates of up to 512 kbps.
• Optional integrated 56/ 64 DDS DSU/ CSU.
• Telnet-provided remote terminal management control.
• FLASH code space for easy software upgrades.
DDS O PERATIO N
DDS is a nationwide service that allows interconnection and
transportation of data at speeds up to 64 kbps. The local ex-
change carriers provide the local loop service to DDS customers
and may provide data for routing Inter-LATA to an
interexchange carrier. With the optional integrated 56/ 64 DDS
DSU, the FSU supports the 56/ 64 kbps DDS service rate yielding
DTE rates of 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 kbps.
5 6 / 6 4 K DDS DSU O PTIO N
The FSU is available with an optional integrated 56/ 64k DSU
(part number 1200130L2). This gives the unit the ability to
directly connect to a frame relay network via a 56 or 64k DDS
circuit.
SN MP MAN AGEMEN T
SNMP management capability is provided inband with support
for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), and
ADTRAN Enterprise MIB. Telnet capability is also supported.
For non-SNMP environments, VT 100 and front panel operation
is supported.

DCE Co n n e cto r
The connector labeled DCE provides connection to an external
DSU/ CSU. The pinouts for this connector are shown in the
appendix Pinouts.
The connection between the FSU and an external DSU is a direct
connection. When connecting to an external DSU, the FSU emulates
an externally timed DTE interface connected directly to the DCE
interface of the external device.
DTE Co n n e cto rs
DTE devices are connected to the DTE connectors using either an
RS-232 DTE cable or a CCITT V.35 DTE adapter cable. The
maximum cable lengths recommended are 50 feet for the RS-232
and 100 feet for the CCITT V.35. The pin assignments are listed
in the appendix Pinouts.
The V.35 adapter cable is recommended for use with data rates
above 19.2 kbps. A low capacitance RS-232 cable works up to 56
kbps. The DTE ports are configured through the front panel or
the VT 100 control port. The DTE ports can operate in asynchro-
nous or synchronous modes.
Ma in Te lco Co n n e cto r
The Main connector is an eight-position modular jack which
provides connection to the dedicated (DDS) network. See the
appendix Pinouts for the Main connector's pin assignments.
Ba ck u p Co n n e cto r
The eight-position modular jack labeled BACKUP is provided to
allow future enhancements to the FSU (dial backup options).

Applications
This chapter provides examples of some common FSU applica-
tions. The examples include SNA/ SDLC with local spoofing,
SNMP/ Telnet management, bisync point-to-point and multi-
point, and transparent applications. The configuration selections
given in these examples may need modification based on your
network configuration.
SN A/ SDLC w ith Lo ca l Sp o o fin g
When used in an SNA/ SDLC network, the FSU provides local
spoofing by emulating the primary or secondary SDLC roles (see
Figure 4-1). The FSU performs conversion from SDLC to frame
relay and also terminates SDLC links, providing primary and
secondary emulation between FSUs. Local spoofing improves
performance by reducing traffic across the frame relay network
and allows definite response times on the SDLC links.
To perform spoofing, the FSU automatically sets itself up to
provide primary or secondary emulation based on the receipt of
SNRM (set normal response mode) from an SDLC device. The
FSU looks for SNRM on all ports and assumes a secondary role
once SNRM is received. The FSU then brings up the LLC2 link
across the frame relay network to another FRAD which assumes
a primary role. This allows the FSU to operate with PU 2.1
devices.
Different roles can be assumed for each SDLC session. Discon-
nection starts the role determination procedure again.

Chapter 4. Applications
In all cases, the FSU is transparent to the XID (exchange identifica-
tion) negotiation between any two network devices.
The FSU uses LLC protocol (mode 2) to transport SDLC informa-
tion frames. This protocol ensures a reliable link across frame
relay, providing protection from frame loss and excessive delays.
The encapsulation method uses the RFC 1490 format. See Table
4-A for an example of how to configure the FSU for this applica-
tion.

SN A a n d LAN Ap p lica tio n w ith SN MP/ Te ln e t Ma n a g e m e n t
When used in a mixed environment consisting of both SNA and
LAN networks, the FSU serves as a concentrator, allowing both
networks access to one frame relay link. The example shown in
Figure 4-2 shows DTE 1 configured for SDLC protocol (as in the
previous example). DTE 2 is configured for frame relay proto-
col, providing the LAN gateway/ router with frame relay access.
The FSU routes data at the DLCI level using the DTE 2 frame
relay address table. The FSU emulates the network end of the
UNI signaling protocol for the DTE port while emulating the
CPE end for the network port. PVC status information from the
frame relay network is stored and used for full status requests
from the router attached to the DTE port.
A local DLCI is set up between the router and the FSU. This
Management DLCI carries the SNMP and telnet traffic destined
for the FSU. This DLCI is included in the UNI full status re-
sponses to the router. The FSU IP address must be mapped to
the management DLCI in the LAN router's route table (see the
following note). With this path, an SNMP manager located
anywhere in the network can access the FSU's SNMP and telnet
information. See Table 4-B for an example configuration.
RIP and inverse ARP are not used for the FSU DTE frame relay port.

The FSU can be used to connect IBM 3780/ 2780 (see IBM manual
number GA27-3004-2) bisync controllers and a host across a
frame relay network. Point-to-point and multi-point configura-
tions are supported at speeds up to 19200 bps. The LLC protocol
(mode 2) is used to provide a reliable transport layer across the
frame relay network. In a multi-point configuration the FSU
performs local spoofing, minimizing traffic across the frame
relay network. Sample network illustrations for both point-to-
point and multi-point are shown in Figures 4-3 and 4-4.
See Table 4-C for an example configuration for the point-to-point
application.

Tra n sp a re n t Ap p lica tio n
In cases when the user protocol is not supported by the FSU, the
transparent mode may be used. Transparent bit-oriented
protocol (BOP) or transparent asynchronous protocol may be
selected. This can be used for point-to-point connections only
because the FSU is transparent to the protocol address formats.
In the transparent BOP protocol, the FSU accepts an HDLC-like
protocol and encapsulates the information field of the HDLC
frames, transporting them across the frame relay network to the
specified virtual circuit and remote FSU port number. The
incoming frames must be spaced with at least one flag byte
(0x7E) and contain two bytes of CRC16 at the end of each frame.
Asynchronous protocols are supported by using the transparent
async mode. The FSU buffers async characters and encapsulates
the data portion of each character for transport across frame
relay using a programmable DLCI and remote FSU port number.
See Figure 4-5 and Table 4-D for an example of a transparent
BOP configuration. See Figure 4-6 and Table 4-E for an example
of a transparent asynchronous application.

Chapter 5. Configuration Overview
The FSU contains a default set of configuration options stored in
read-only memory (see the appendix Default Configuration
Profile). The unit is shipped from the factory with this profile
loaded into the current (nonvolatile configuration) memory. If
this profile matches requirements for the system, then no
additional configuration is required to put the unit into service.
If the profile does not match system requirements, it can be
modified. When the profile is modified, it is stored in the
current (nonvolatile configuration) memory. The FSU is then
configured with that profile every time power is turned on.
For detailed information on configuration see the chapters DTE
Port Configuration, Network Port Configuration, IP Routing, and
System Configuration.
Configuration menus are shown in Figures 5-2 (for the Front
Panel) and 5-3 (for the VT 100 terminal).

Chapter 6. DTE Port Configuration
Fra m e Re la y Pro to co l
The frame relay protocol is a synchronous protocol used to
concentrate two different devices into a common frame relay link
to the network. While configured for frame relay protocol, the
FSU accepts frame relay frames from a router or a FRAD and
routes to/ from the network port based on the DLCI address.
The address can be modified or preserved from the DTE and
network side based on the frame relay address table. FECN,
BECN, DE, and C/ R states are not changed as frames are trans-
ferred between the DTE and the network ports. The menu tree
in Figure 6-4 shows the choices available when the frame relay
protocol is selected.

Sig n a lin g Ty p e (SIGN AL)
Set the signaling type for the DTE port to match the signaling
type of the connected DTE device. Choices are none, FRF LMI,
ANSI T1.617-D, and ITU-T Q.933-A. If none is chosen, the
signaling state for the DTE port is always up.
T3 9 2
Set the timeout between polling intervals. This parameter needs
to be a few seconds longer than the T391 setting of the attached
frame relay device.
N 3 9 2 a n d N 3 9 3
These parameters define the error threshold for the UNI formed
by the FSU DTE port and the attached frame relay device. If the
error threshold is met, the signaling state status is changed to
down, which indicates a service-affecting condition. This
condition is cleared once N393 consecutive error-free events are
received. N392 defines the number of errors required in a given
event window, while N393 defines the number of polling events
in each window.
For example:
If N392=3 and N393=4, then if three errors occur within any four
events the interface is determined inactive.
The status of the connection can be viewed in the Status menu
under DTE Port Signaling State. The status will return to active
once the threshold is no longer exceeded.

If the attached router or FRAD is used to route SNMP/ telnet
frames to the FSU, set the Management DLCI to a unique value
that identifies the virtual circuit between the router/ FRAD and
the FSU. The router/ FRAD must also be configured to route the
FSU IP address to this DLCI. The IP address and subnet mask
for the DTE port must also be set.

SDLC Pro to co l
SDLC is a synchronous, bit-oriented, full-duplex, Layer 2
protocol used to connect SDLC devices to a frame relay network.
At Layer 2, SNA networks use SDLC between FEPs (front-end
processors) and cluster controllers. This protocol selection
provides Logical Link Control Type 2 (LLC2). LLC2 defines the
data link frame header and supports the multiplexing of one or
more data links to/ from separate service access points (SAPs).
Type 2 provides acknowledged, connection-oriented service. See
Figure 6-5.
The PU (physical unit) address, LLC2 SSAP, LLC2 DSAP, and
outgoing DLCI are used to set up an end-to-end SDLC session
for each PU in the network. The PU address elements should
match the address of each controller address attached to the port.
The DLCI determines the path across the frame relay network
and is given by the service provider. The SSAP/ DSAP pairs are
user-defined but should match between two FSUs for each SDLC
session.
All PU addresses for a port must be unique, but it is not necessary that
they match the PU address at the remote end. The SSAP/DSAP/DLCI
is used to make the connection across the frame relay network.

Tra n sp a re n t BO P (TRAN S BO P)
Transparent BOP is a synchronous mode which can accept any
HDLC-like protocol as input. This setting allows the FSU to
connect to devices even if the FSU does not understand their
protocol's addressing and controlling techniques. The FSU
becomes transparent to the data link layer protocol and provides
end-to-end connectivity between two HDLC-like devices. See
Figure 6-6 for the Transparent BOP menu tree.

relay UNI interface. The FSU supports three standard PVC
signaling formats: LMI, ANSI T1.617-D, and ITU Q.933-A. The
selected signaling format is used to poll the network end of the
UNI interface and retrieve virtual circuit information. Option-
ally the polling process can be disabled.
User data is encapsulated into standard frame relay formatted
frames using two methods. FRF 3.1 IA procedures are used for
IP and LLC2 protocols while a proprietary method is used for
transparent protocol mode. Virtual circuit sharing is allowed for
both methods.
Configure the Network Port before the DTE Ports. Selections made will
affect the choices available for the DTE ports.
Co n n e ctio n
Connection is made through the internal DDS 56/ 64 DSU (if
installed). If this option is not installed, use an external DDS or
fractional T1 (up to 512 kbps) DSU.

N 3 9 2 a n d N 3 9 3
These parameters define the error threshold for the UNI formed
by the FSU network port and the frame relay switch. If the error
threshold is met, the signaling state status is changed to down,
which indicates a service-affecting condition. This condition is
cleared once N393 consecutive error-free events are received.
N392 defines the number of errors required in a given event
window, while N393 defines the number of polling events in
each window.
For example:
If N392=3 and N393= 4, then if three errors occur within any four
events the interface is determined inactive.
The status of the connection can be viewed in the Status menu
under Network Port Signaling State. The status will return to
active again once the threshold is no longer exceeded.
Re m o te FECN N o tifica tio n (RFECN )
Enable/ disable the FSU to issue remote FECN (forward explicit

ADTRAN FSUs and can only be used with an ADTRAN FSU on
both ends of the virtual circuit.
The network service provider should recommend the values entered into
the T391, N391, N392, and N393 fields.

IP Routing
IP RO UTIN G W ITH THE FSU
The FSU contains an IP router function to resolve paths for IP
packets received. This function is used regardless of encapsula-
tion protocol and port received from.
The heart of the routing system is a routing table which can be
generated manually, automatically, or a combination of the two.
Manual entry is preferred in cases where there are few routes.
This minimizes traffic created by routing protocols used in the
automatic method. The automatic method cuts down on manual
entry for large route tables and allows for routes to be changed
without service interruption.
Another important element in routing is the default gateway
route. This is used while routes are being formed automatically
and is a convenient way to direct all IP packets in cases where
only one route is needed.
Routing internet protocol (RIP) can be enabled for each port
configured for IP encapsulation. The Tx RIP parameter enables
the FSU to share the internal routing table with other routers and
FRADs attached to the port. The Rx RIP parameter enables the
FSU to process routing table information from other routers and
FRADs attached to the port.
In addition to RIP, the network port uses inverse ARP (RFC 1490)
to associate peer router/ FRAD IP addresses to PVC addresses.

IP Ro u te Ta b le
Use these menu options to build a table of addresses for routing
data packets based on their IP address. When a packet with the
specified IP address is received, it is sent out through the se-
lected port on the specified DLCI. See Figure 8-2.
The IP route table can be used in conjunction with RIP protocol
to provide routing paths for the entire IP network. If an IP
packet is received with a destination IP not located in the inter-
nal routing table (static or RIP), then the gateway route is used.

shown:
Pin g s Se n t
This field shows the number of pings sent (always 10).
Re sp o n se s
This field shows the number of responses received from the

This field shows the shortest round-trip delay of the received
responses. Round-trip delay is counted from the time the ping is
sent until the response is received.
Ma x Tim e
This field shows the longest round-trip delay of the received
responses. If a response is not received before the unit times out,
the delay is not calculated in.
Avg Tim e
This field shows the average response time based on all received
responses.

bridge
A device that supports LAN-to-LAN communications. Bridges may be equipped
to provide frame relay support to the LAN devices they serve. A frame relay
capable bridge encapsulates LAN frames in frame relay frames and feeds them to
a frame relay switch for transmission across the network. A frame relay capable
bridge also receives frame relay frames from the network, strips the frame relay
frame off each LAN frame, and passes the LAN frame on to the end device.
Bridges are generally used to connect LAN segments to other LAN segments or
to a WAN. They route traffic on the Level 2 LAN protocol (e.g. the Media Access
Control address), which occupies the lower sub-layer of the LAN OSI data link
layer. See also router.
CCITT
Consultive Committee for International Telphony and Telegraphy. A standards
organization that devises and proposes recommendations for international
communications. See also American National Standards Institute (ANSI).
CD
carrier detect. A signal generated by a modem or DSU/ CSU. CD indicates the
presence of a carrier signal on a communications link.
channel service unit
CSU. A device used to connect a digital phone line (T1 or Switched 56 line)
coming in from the phone company to either a multiplexer, channel bank, or
directly to another device producing a digital signal; for example, a digital PBX, a
PC, or data communications device. A CSU performs certain line-conditioning
and equalization functions, and responds to loopback commands sent from the
central office. A CSU regenerates digital signals. It monitors them for problems,
and provides a way of testing the digital circuit.
clocking
An oscillator-generated signal that provides a timing reference for a transmission
link. A clock provides signals used in a transmission system to control the
timing of certain functions. The clock has two functions, (1) to generate periodic
signals for synchronization and (2) to provide a time base.
CPE

between the DCE and the DTE is that pins two and three are reversed.
end device
The ultimate source or destination of data flowing through a frame relay network
sometimes referred to as DTE. As a source device, it sends data to an interface
device for encapsulation in a frame relay frame. As a destination device, it
receives de-encapsulated data (i.e., the frame relay frame is stripped off, leaving
only the user's data) from the interface device. Also see DCE.
encapsulation
A process by which an interface device places an end device's protocol-specific
frames inside a frame rely frame. The network accepts only frames formatted
specifically for frame relay; therefore interface devices acting as interfaces to a
frame relay network must perform encapsulation. See also interface device or
frame relay capable interface device.
E1
Transmission rate of 2.048 Mbps on E1 communications lines. An E1 facility
carries a 2.048 Mbps digital signal. See also T1 and channel.

Glossary
synchronous
Communications in which the timing is achieved by sharing a single clock. Each
end of the transmission synchronizes itself with the use of clocks and
information sent along with the transmitted data.
synchronous data link control (SDLC)
A link-level communications protocol used in an international business machines
(IBM) systems Network Architecture (SNA) network that manages synchronous,
code-transparent, serial information transfer over a link connection. SDLC is a
subset of the HDLC protocol developed by ISO.
T1
Transmission rate of 1.544 Mbps on T1 communication lines. A T1 facility
carriers a 1.544 Mbps digital signal. Also referred to as digital signal level 1 (DS-
1). See also E1 and channel.
trunk line
A communications line connecting two frame relay switches to each other.
VT 100
A non-intelligent terminal or terminal emulation mode used for asynchronous
communications. Used to configure the FSU.
