Chapter 1 Introduction
UNDERSTANDING FRAME RELAY
Frame relay is a wide area network (WAN) service designed to
minimize physical connectio ns. 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 Express 5200.
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 addr ess 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

Product Overview
The ADTRAN Express 5200 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 Express 5200 provides an easy-to-use interface for customers
migrating existing services or developing new applications for
operation over frame relay networks.
The Express 5200 provides high-quality voice and fax capabilities
to remote locations without expensive toll charges. In frame relay
networks, the Express 5200 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 a voice option card. Options
include: Dual FXS, Dual FXO, and Dual E&M.
The Express 5200 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. See
the appendix Pinouts on page A-1 for the pin assignments for these
interfaces.
The Express 5200 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 ro uting 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.

DDS Operation
DDS is a nationwide service that allows interconnection and
transportation of data at speeds up to 64 kbps. The local exchange
carriers provide the local loop service to DDS customers and may
provide data for routing Inter-LATA to an interexchange carrier.
The integrated 56/64 DDS DSU supports the 56/64 kbps DDS
service rate.
SNMP
The Express 5200'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,
61202175L1-1 Express 5200 User Manual 1-3
Chapter 1. Introduction
or async PPP protocol. The Express 5200 supports the MIB-II
standard, RFC 1213, and the ADTRAN Enterprise Specific MIB.
MIB files are available from ADTRAN in the support section of the
ADTRAN Web page at www.adtran.com.
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, contr ols, and pr esents data pertinent
to the operation of the network devices. It resides on a network
management stati on.
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 m anager.
MIB
Index to the organized data within a netw ork device. It defines the
operation parameters that can be controlled or monitored.
TELNET
TELNET provides a password-protected, remote login facility to
the Express 5200. TELNET allows a user on a network manager to
control the Express 5200 through the terminal menus. See the
section SNA and LAN Application with SNMP/TELNET Management
on page 4-4 for more information.
Voice Compression
The Express 5200 voice option cards employ 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

E&M Module
Chapter 1. Introduction
14.4 kbps. The Express 5200 dynamically allocates bandwidth to
voice and data applications. This results in al l bandwidth being
available for data applications in the absence of voice or fax.
The FXS module provides two 2-wire compressed voice interfaces
and serves as the source of line current and ringing voltage. The
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.
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 FXO serves as the office
side of a foreign exchange FXS/FXO application.
The E&M module provides two 2- or 4-wire compressed voice
interfaces for use in E&M applications.
Dial Backup Operation
The Express 5200 supports dial backup of point-to-point DDS
circuits or point-to-point frame relay circuits. For DDS backup, the
Express 5200 enters dial backup based on physical line faults.
During dial backup, the Express 5200 monitors the main line
integrity and drops the dial backup call when the main line is
restored.
For frame relay dial backup, the Express 5200 monitors the physical
line condition as well as the signaling state of the frame relay
circuit. A loss of signaling on either end of the circuit causes the
Express 5200 to enter dial backup. During dial backup, the
Express 5200 constantly monitors the physical state of the network.
It also attempts to re-establish signaling on the main line. Once
61202175L1-1 Express 5200 User Manual 1-5
Chapter 1. Introduction
both the physical integrity and the signaling state are restored, the
unit drops the dial backup call and reverts to the main line.
For frame relay dial backup, either Express 5200 can originate a dial backup connection. The answer/originate option has no effect in frame relay
mode.
Only point-to-point frame relay is s upporte d with the Express 5200. The
Express 5200 only supports one network connection at a time. Therefore,
when a dial backup connection is made, the main network port is disconnected from the data path. This isolates any other nodes on a frame relay
network if a dial backup connection is established with a single node.
The Express 5200's unique DBU cards are field-installable by the
customer. See the section DBU and Voice Interface Card S lot s on page
2-4 for information on installing DBU cards. The four backup
options are described in the following sectio ns. Contact the local
telco provider to determine which services are available in your
area.
