Introduction
UNDERSTANDING 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 5622 ESP.
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 information 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

equipment. This DLCI is valid until the call is disconnected and
may be assigned a different value each time a call is requested.
PRODUCT OVERVIEW
The ADTRAN FSU 5622 ESP is a standalone frame relay access
device (FRAD) that provides a cost-effective means of transporting voice and multi-protocol data over frame relay or DDS
networks. The FSU 5622 ESP provides an easy-to-use interface
for customers migrating existing services or developing new
applications for operation over frame relay networks.
The FSU 5622 ESP provides high-quality voice and fax capabilities to remote locations without expensive toll charges. In frame
relay networks the FSU 5622 ESP allows voice and data to share
the same PVC eliminating unnecessary PVC charges associated
with other vendor’s voice and data frame relay products. Two
voice ports are provided when configured with an ESP option
card. Options include: ESP Dual FXS, ESP Dual FXO, and ESP
Dual E&M.
The FSU 5622 ESP provides two independent DTE interfaces for
connecting non-frame relay devices to the frame relay network.
These ports can be configured for either EIA-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 5622 ESP handles each frame of the user data in a threestep 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 examining 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 reencapsulating based on the destination port configuration. A
similar process is used for frame relay frames received on the
network port.

Chapter 1. Introduction
SNMP
The term SNMP broadly refers to the message protocols used to
exchange information between the network and the managed
devices, as well as to the structure of network management data
bases. SNMP has three basic components:
Network Manager
Control program that collects, controls, and presents data
pertinent to the operation of the network devices. It resides on a
network management station.
Agent
Control program that resides in each network device connected.
This program responds to queries and commands from the
network manager and returns requested information or invokes
configuration changes initiated by the manager.
MIB
Index to the organized data within a network device. It defines
the operation parameters that can be controlled or monitored.
The FSU 5622 ESP supports the MIB-II standard, RFC 1213, and
ADTRAN Enterprise Specific MIB.
MIB files are available from ADTRAN in the support section of the
ADTRAN Web page at www.adtran.com.
The FSU 5622 ESP's embedded SNMP feature allows the unit to
be accessed and controlled by a network manager through the
network interface or through a DTE port running frame relay,
SLIP, or async PPP protocol.
TELNET
TELNET provides a password-protected, remote login facility to

VOICE COMPRESSION
The FSU 5622 ESP voice option cards employ MP-MLQ voice
compression technology to provide toll-quality voice using
significantly less bandwidth than traditional voice channels. In
addition to supporting voice calls, the cards support group 3
facsimile up to 9.6 kbps. Each voice channel requires an aggregate bandwidth of 9.6 kbps for voice or 12 kbps for facsimile.
The FSU 5622 ESP dynamically allocates bandwidth to voice and
data applications. This results in all bandwidth being available
for data applications in the absence of voice or fax.
FXS Module
The FXS module provides two 2-wire compressed voice interfaces and serves as the source of line current and ringing voltage.
The ESP FXS serves as the station side of a foreign exchange
FXS/FXO application. The FXS may also be paired with another
FXS to provide private line automatic ringdown (PLAR) function
across the WAN.
FXO Module
The FXO module provides two 2-wire compressed voice interfaces and provides a load for line current. The module includes
a ring detector and a line current detector. The ESP FXO serves
as the office side of a foreign exchange FXS/FXO application.
E&M Module
The E&M module provides two 2- or 4-wire compressed voice
interfaces for use in E&M applications.

Applications
This chapter provides examples of some common FSU 5622 ESP
data and voice applications. The data examples include SNA/
SDLC with local spoofing, SNMP/TELNET management, bisync
point-to-point and multi-point, and transparent applications.
The voice applications include direct FXS/FXO, switched, and
PLAR circuits. The configuration selections given in these
examples may need modification based on your network configuration.
SNA/SDLC with Local Spoofing
When used in an SNA/SDLC network, the FSU 5622 ESP
provides local spoofing by emulating the primary or secondary
SDLC roles (see Figure 4-1). The FSU 5622 ESP performs conversion from SDLC to frame relay and also terminates SDLC links,
providing primary and secondary emulation between FSU 5622
ESPs. 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 5622 ESP 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 5622 ESP looks for SNRM on all ports and
assumes a secondary role once SNRM is received. The FSU 5622
ESP then brings up the LLC2 link across the frame relay network
to another FRAD which assumes a primary role. This allows the
FSU 5622 ESP to operate with PU 2.1 devices.
61200.175L1-1
FSU 5622 ESP User Manual
25
Chapter 4. Applications
Different roles can be assumed for each SDLC session. Disconnection starts the role determination procedure again.
In all cases, the FSU 5622 ESP is transparent to the XID (exchange
identification) negotiation between any two network devices.
The FSU 5622 ESP uses LLC protocol (mode 2) to transport
SDLC information 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 5622 ESP for this application.

Chapter 4. Applications
SNA and LAN Application with SNMP/TELNET Management
When used in a mixed environment consisting of both SNA and
LAN networks, the FSU 5622 ESP 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 protocol, providing the LAN gateway/router with
frame relay access.
The FSU 5622 ESP routes data at the DLCI level using the DTE 2
frame relay address table. The FSU 5622 ESP 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 5622 ESP.
This Management DLCI carries the SNMP and TELNET traffic
destined for the FSU 5622 ESP. This DLCI is included in the UNI
full status responses to the router. The FSU 5622 ESP 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
5622 ESP's SNMP and TELNET information. See Table 4-B for an
example configuration.
RIP and inverse ARP are not used for the FSU 5622 ESP DTE frame
relay port.

Bisync Application
The FSU 5622 ESP 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
configurations 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 5622 ESP 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 multi-point
application.

Transparent Application
In cases when the user protocol is not supported by the FSU 5622
ESP, the transparent mode may be used. Transparent bitoriented protocol (BOP) or transparent asynchronous protocol
may be selected. This can be used for point-to-point connections
only because the FSU 5622 ESP is transparent to the protocol
address formats.
In the transparent BOP protocol, the FSU 5622 ESP 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 5622 ESP
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 5622 ESP buffers async characters and
encapsulates the data portion of each character for transport
across frame relay using a programmable DLCI and remote FSU
5622 ESP 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 4. Applications
Switched Mode Application
Switched mode is used to multiplex several remote extensions
(up to 40) to two host ports (see Figure 4-7). This enables many
remote users to have access to a limited number of access lines
on a call-by-call basis. The host unit typically connects two
extensions to a PBX via an FXO module. The remote units
connect to telephone sets via FXS modules.
The host unit is programmed with the extensions and DLCI
information for all of the remote units. This information is
communicated to the remote units over the network.
External Call Origination
When the telephone set on a remote FSU 5622 ESP is taken offhook, the local FSU 5622 ESP generates dial tone and waits for a
four-digit extension to be entered by the user. Once the extension is entered, the remote FSU 5622 ESP transmits this information to the host FSU 5622 ESP where it is compared to extension
information in the extension/DLCI table. If the extension is not
located, the host assumes the number is external and attempts to
seize an available port and dial the extension on the PBX. If no
port is available, a trunk busy (fast busy) is returned to the
remote port. After the extension is dialed, the data link is
established and the call remains up until the remote FSU 5622
ESP terminates the call.
External Call Reception
When an incoming call is received from the PBX, the host FSU
5622 ESP auto-answers the call and generates dial tone. At this
point the calling party can dial the four-digit extension of the
party they are trying to reach. The host looks up the extension in
the extension/DLCI table and routes the call appropriately. If
the extension does not exist, the FSU 5622 ESP generates a trunk
busy signal back into the PBX. Otherwise, the host routes the
call to the appropriate port. When the remote party answers the
call, the data link is established and the call remains up until the
remote FSU 5622 ESP hangs up or until a loss of line current is
detected on the FXO port.

Chapter 4. Applications
Internal Calls
When the telephone set on a remote FSU 5622 ESP is taken offhook, the local FSU 5622 ESP generates dial tone and waits for
the four-digit extension to be entered. Once the extension is
entered, the remote FSU 5622 ESP transmits this information to
the host FSU 5622 ESP where it is compared to extension information in the extension/DLCI table. If the extension if found in
the extension/DLCI table, then the call is routed to the appropriate extension via the host unit. When the called unit goes offhook, the data link is established and remains up until one of the
two extensions terminates the call.

PLAR Mode Application
PLAR (private line automatic ringdown) mode connects up to
two remote telephone sets to one or two local telephone sets
without a PBX. PLAR mode runs over a point-to-point DDS
network or over a frame relay network. This mode requires the
use of FXS modules on both ends for connection to the telephone
sets. In PLAR mode, taking a phone off-hook rings the opposite
end of the circuit. See Figure 4-8.
For PLAR mode, the DLCI for each voice port must be programmed. In the case of a frame relay circuit, this is the local
DLCI that the voice data is to be carried on. For a point-to-point
circuit, the DLCI value must be non-zero and it must be the same
on both ends of the circuit.

Direct Mode Application
Direct mode is used to set up a typical FXS/FXO extension
arrangement. In this mode, the local unit is connected to a PBX
via an FXO module. The remote unit uses an FXS module to
connect the telephone sets. In this arrangement, the local PBX
extensions are extended across the frame relay or point-to-point
DDS circuit. In direct mode, the FSU FSU 5622 ESP is transparent to the telephone circuit. All signalling information is generated/detected by the attached PBX/telephone.
For direct mode, the DLCI for each voice port must be programmed. In the case of a frame relay circuit, this is the local
DLCI that the voice data is to be carried on. For a point-to-point
circuit, the DLCI value must be non-zero and it must be the same
on both ends of the circuit. See Figure 4-9.

Chapter 5. Configuration Overview
The FSU 5622 ESP contains a default set of configuration options
stored in read-only memory. 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.
For detailed information on configuration see the chapters DTE
Port Configuration, Configuring the Voice Interfaces, Network Port
Configuration, Configuring Dial Backup Options, IP Routing, and
System Configuration.

Frame Relay Protocol
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 5622 ESP 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
transferred 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.

Signaling Type (SIGNAL)
Set the signaling type for the DTE port to match the signaling
type of the connected DTE device. Choices are none, 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.
T392
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.
N392 and N393
These parameters define the error threshold for the UNI formed
by the FSU 5622 ESP 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.
Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI
If the attached router or FRAD is used to route SNMP/TELNET
frames to the FSU 5622 ESP, set the Management DLCI to a
unique value that identifies the virtual circuit between the
router/FRAD and the FSU 5622 ESP. The router/FRAD must
also be configured to route the FSU 5622 ESP IP address to this
DLCI. The IP address and subnet mask for the DTE port must
also be set.

Setting the IP address to 0.0.0.0 and setting the Mng DLCI to a
value not used by the attached frame relay device disables this
feature.
IP Address (IP ADDRESS)
Enter the FSU 5622 ESP IP address. Each port capable of carrying IP traffic has its own unique IP address. See the previous
section, Guidelines for Configuring IP Addr, Subnet Mask, and Mng
DLCI, for more information.
Subnet Mask
Enter the subnet number assigned to the network formed by the
FSU 5622 ESP and the other FRAD/routers across the frame
relay network. See the section, Guidelines for Configuring IP
Addr, Subnet Mask, and Mng DLCI, for more information.
Management DLCI (MNG DLCI)
Enter the management data link connection identifier. The
Management DLCI is a special DLCI used between the attached
DTE device and the FSU 5622 ESP to carry SNMP and TELNET
packets to/from the FSU 5622 ESP on the DTE port. See the
section, Guidelines for Configuring IP Addr, Subnet Mask, and Mng

SDLC Protocol
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 FSU 5622 ESPs 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.

Chapter 7. Configuring the Voice Interfaces
Mode
Select either DIRECT or SWITCHED mode for the voice interface.
Direct Mode
Direct mode is used to accomplish a one-to-one mapping of
ports across a frame relay network. In this mode, L1 and L2 on
the local unit are connected to L1 and L2 on the remote unit.
With this option, one or two extensions can be extended across
the frame relay or DDS network by utilizing an FXO module on
the local unit and an FXS module on the remote unit. PLAR
circuits are also supported by using FXS modules on both ends
of the circuit.
Switched Mode
Switched mode is used to multiplex several remote extensions
(up to 40) to two host ports. This enables many remote users to
have access to a limited number of access lines on a call-by-call
basis. The host unit typically connects two extensions to a PBX
via an FXO module. The remote units connect to telephone sets
via FXS modules. See the chapter Applications for an example of
a switched application.
Host/Rem
Configure the unit to be either the HOST unit or a REMOTE unit.
There must be only one host unit in a switched environment.
Typically, the host unit connects to the PBX via FXO connections.
The host unit maintains all of the extension/DLCI information.
All units other than the host are set up as remote units. No other
configuration is required for remote units.
This option is available only when the MODE is set for SWITCHED.

associated with the voice data on a remote FSU 5622 ESP and the
extension for the two voice ports connected to that DLCI. The
FSU 5622 ESP supports up to 20 DLCIs which yield a total of 40
voice ports. The front panel Next, Previous, Add, and Delete
keys are used to edit this table. The DLCI/Extension information is communicated to the remote units over the network so
configuration is not required on the remote units.

NETWORK PORT
Access the Network Port menus by selecting Network Port from
the Configuration menu. See the menu tree in Figure 8-1. The
network port is always used in frame relay protocol configurations. The network port terminates the user end of the frame
relay UNI interface. The FSU 5622 ESP 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.
Optionally 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.

N391
Determine how many link integrity polls occur in between full

N392 and N393
These parameters define the error threshold for the UNI formed
by the FSU 5622 ESP 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.
Remote FECN Notification (RFECN)
Enable/disable the FSU 5622 ESP to issue remote FECN (forward explicit congestion notification). This feature ensures that
a frame will be generated in the reverse direction upon receiving
a frame with the FECN bit enabled. This is a proprietary feature
with ADTRAN FSU 5622 ESPs and can only be used with an
ADTRAN FSU 5622 ESP on both ends of the virtual circuit.
The network service provider should recommend the values entered into
the T391, N391, N392, and N393 fields.

Passcode
The dial backup passcode adds an additional level of security to
the FSU 5622 ESP. A passcode of one to ten characters can be
programmed into the unit.
When a dial backup connection is established, the originate unit
transmits a pre-programmed passcode to the answer unit over
the dial backup connection before the connection is considered
valid. The answer unit compares the received passcode to a preprogrammed passcode. If the passcode matches, the receive unit
sends a Passcode OK message to the originate unit and goes online. If the passcode does not match, the receive unit sends an
Invalid Passcode message to the originate unit and terminates
the dial backup connection. If a passcode is not received by an
answer unit with passcode enable, or if the Passcode OK
message is not received by an originate unit with passcode
enable, the dial backup connection is terminated.

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 5622 ESP to share the internal routing table with other
routers and FRADs attached to the port. The Rx RIP parameter
enables the FSU 5622 ESP 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.

The FSU 5622 ESP can also respond to requests from peer
routers/FRADs seeking an association for their tables. The
transmit and receive inverse ARP section can be independently
enabled.
Access IP Routing selections by first choosing 1 CONFIGURATION from the Main menu. Then choose IP ROUTING from the
Configuration Menu. When using the VT 100 terminal interface,
the screen in Figure 10-1 will appear. Full menu trees for these

IP Route Table
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 selected port on the specified DLCI. See Figure 10-2.
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 internal routing table (static or RIP), then the gateway route is used.

This example provides a route for IP address range 192.239.232.1
through 192.239.232.254 using the network port and virtual
circuit 16. See the following parameter descriptions.
IP Address (IP ADDR)
Enter the IP address to be routed. This entry identifies an
individual host or an entire subnet. To address an entire subnet,
enter a value with the host portion equal to 0.
Destination Port (DST PORT)
Select the port on the FSU 5622 ESP used to transmit the packets
with the specified IP address.
Destination DLCI (DST DLCI)
Enter the virtual circuit to be used when the network port is part
of the destination IP path. This selection is only applicable if the
corresponding destination port element is set for Network port.

Gateway IP Address (GW IP ADD)
Enter the Gateway IP address. If an IP packet with an unknown
IP address is received, the FSU 5622 ESP sends it to the Gateway
(which is a router or another FRAD).
Gateway Port (GW PORT)
Enter the port from which the gateway can be reached.
Gateway DLCI (GW DLCI)
If the gateway port is set to Network, this parameter identifies
the virtual circuit used to reach the gateway.
Transmit ARP Packets (TX ARP)
This parameter enables the transmit portion of the network port
inverse ARP protocol. If enabled, inverse ARP messages will be
sent to every DLCI assigned to the network port each ARP
refresh time period and inverse ARP responses will be generated.
Process Received ARP Packets (RX ARP)
This parameter enables the receive portion of the network port
inverse ARP protocol. If enabled, all inverse ARP messages
received are used to associate peer IP addresses with DLCI
values.
ARP Refresh Time (ARP REF)
Determine how often an inverse ARP request is sent to every
DLCI assigned to the network port.
ARP is used in conjunction with RIP to dynamically resolve IP routes
and should be enabled if RIP is enabled.

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.
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

only the user's data) from the interface device.
file server
In the context of frame relay network supporting LAN-to-LAN communications,
a device connecting a series of workstations within a given LAN. The device
performs error recover and flow control functions as well as end-to-end
