Chapter 1 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.
Chapter 1. Introduction 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 Express 5210 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.
Chapter 1.
Chapter 1. Introduction SNMP The Express 5210's embedded SNMP feature allows the unit to be accessed and controlled by a network manager through one of the following: • the network interface • a DTE port running frame relay, SLIP, or async PPP protocol • the 10BaseT LAN port The Express 5210 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.
Chapter 1. Introduction control the Express 5210 through the terminal menus. See the section TELNET Utility on page 4-1 for more information on setting up a TELNET session. Voice Compression The Express 5210 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 14.4 kbps.
Chapter 1. Introduction Dial Backup Operation The Express 5210 supports dial backup of point-to-point DDS circuits or frame relay circuits. For DDS backup, the Express 5210 enters dial backup based on physical line faults. During dial backup, the Express 5210 monitors the main line integrity and drops the dial backup call when the main line is restored. For frame relay dial backup, the Express 5210 monitors the physical line condition as well as the signaling state of the frame relay circuit.
Chapter 1. Introduction DBU Card Option Descriptions 4-Wire Switched 56 DBU Card This dial-up 4-wire SW56 card allows you to pay for data connection only for the time the unit is active. The regional operating companies provide the 4-wire local loop service to SW56 customers. V.34 DBU Card This module backs up the leased line application at data rates up to 33.6 kbps over an ordinary telephone network. ISDN DBU Card 1B+D Basic Rate ISDN service provides backup over a switched 56/64 kbps circuit.

Chapter 5 Applications This chapter provides examples of some common Express 5210 data and voice applications. The data examples include SNA/ SDLC with local spoofing, transparent, and LAN applications. The voice applications (which begin on page 5-9) include switched, daisy-chaining, PLAR circuits, and direct FXS/FXO. The configuration selections given in these examples may need modification based on your network configuration.
Chapter 5. Applications Different roles can be assumed for each SDLC session. Disconnection starts the role determination procedure again. In all cases, the Express 5210 is transparent to the XID (exchange identification) negotiation between any two network devices. The Express 5210 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.

Chapter 5. Applications Transparent Application In cases when the user protocol is not supported by the Express 5210, 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 Express 5210 is transparent to the protocol address formats.

Chapter 5. Applications VOICE APPLICATIONS Voice over frame relay can be accomplished using the Express 5210 with an optional dual voice card installed (Dual FXO, FXS, or E&M card). The following sections describe voice application examples using the Express 5210. Examples include switched mode (page 5-9), daisy-chaining (page 5-11), PLAR mode (page 5-12), and direct FXS/FXO (page 5-13).
Chapter 5. Applications 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 Express 5210 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 Express 5210 hangs up or until a loss of line current is detected on the FXO port.
Chapter 5. Applications Figure 5-5. Switched Mode Application Daisy-Chaining Over Frame Relay In this configuration, multiple units are daisy-chained at the host site to accommodate switched OPX (off premise extension) lines. See Figure 5-6. The Express 5210 can be daisy-chained on the host end to accommodate more PBX extensions.
Chapter 5. Applications Figure 5-6. Daisy-Chaining Application 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 5-7.
Chapter 5. Applications Figure 5-7. PLAR Mode Application 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 Express 5210 is transparent to the telephone circuit.

The HISTORY INTERVAL COUNT field shows how many intervals can be stored at a time.
Chapter 12 IP Setup IP ROUTING WITH THE EXPRESS 5210 The Express 5210 contains an IP router function to resolve paths for IP packets received. This function is used regardless of encapsulation 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.
Chapter 12. IP Setup In addition to RIP, the network port uses inverse ARP (RFC 1490) to associate peer router/FRAD IP addresses to PVC addresses. The Express 5210 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 choosing IP SETUP from the MAIN menu. Then choose IP. Figure 12-1 shows the front panel IP SETUP menu tree.

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 Telephony and Telegraphy.
Appendix D. Glossary 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. CTS clear to send. A signal on the DTE interface indicating that the DCE is clear to send data.
Appendix D. Glossary DSU loopback A telco initiated test which loops the DSU back to the telco and is used to test the DDS circuit as well as the DSU/CSU. DTE data terminal equipment. The end-user terminal or computer that plugs into the termination point (DCE) of a communications circuit. The main difference between the DCE and the DTE is that pins two and three are reversed. encapsulation A process by which an interface device places an end device's protocol-specific frames inside a frame rely frame.
Appendix D. Glossary frame-relay-capable interface device A communications device that performs encapsulation. Frame-relay-capable routers and bridges are examples of interface devices used to interface the customer's equipment to frame relay network. See also interface device and encapsulation. frame relay frame A variable-length unit of data, in frame-relay format that is transmitted through a frame relay network as pure data. Contrast with packet. See also Q.922A.
Appendix D. Glossary ISDN Integrated Services Digital Network. A network architecture that enables end-toend digital connections. The network supports diverse services through integrated access arrangements and defines a limited set of standard, multipurpose interfaces for equipment vendors, network providers, and customers. Interworking with a public switched telephone network is retained. LAN local area network.
Appendix D. Glossary PVC permanent virtual circuit. A frame relay logical link, whose endpoints and class of service are defined by network management. Analogous to an X.25 permanent virtual circuit, a PVC consists of the originating frame relay network element address, originating data link control identifier, terminating frame relay network element address, and termination data link control identifier. Originating refers to the access interface form which the PVC is initiated.
Appendix D. Glossary SNMP simple network management protocol. A control and reporting scheme widely used to manage devices from different vendors. SNMP operates on top of the Internet protocol. SR data set ready. A signal on the EIA-232 interface that indicates if the communications is connected and ready to start handshaking control signals so communications can begin.
