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 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.
Chapter 1. Introduction The major features of the Express 5200 are as follows: • Dual voice port support; options include Dual FXS, Dual FXO, and Dual E&M • Two independent DTE data ports • Integral 56/64 DDS DSU/CSU • SNMP/TELNET management • RFC 1490 encapsulation for IP and LLC2 • SDLC local port spoofing • Automatic or manual dial backup for DDS operation • Dial backup available with DBU cards; options include 4-wire Switched 56, V.
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.
Chapter 1. Introduction 14.4 kbps. The Express 5200 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 FXS serves as the station side of a foreign exchange FXS/FXO application.
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 supported with the Express 5200. The Express 5200 only supports one network connection at a time.

Chapter 4 Applications This chapter provides examples of some common Express 5200 data and voice applications. The data examples include SNA/ SDLC with local spoofing, SNMP/TELNET management, bisync point-to-point, bisync multi-point, and transparent applications. The voice applications include switched, voice over frame relay, PLAR circuits, and direct FXS/FXO. The configuration selections given in these examples may need modification based on your network configuration.
Chapter 4. Applications assumes a primary role. This allows the Express 5200 to operate with PU 2.1 devices. Different roles can be assumed for each SDLC session. Disconnection starts the role determination procedure again. In all cases, the Express 5200 is transparent to the XID (exchange identification) negotiation between any two network devices. The Express 5200 uses LLC protocol (mode 2) to transport SDLC information frames.

Chapter 4. Applications External Call Origination When the telephone set on a remote Express 5200 is taken off-hook, the local Express 5200 generates dial tone and waits for an extension to be entered by the user. Once the extension is entered, the remote Express 5200 transmits this information to the host Express 5200, where it is compared to extension information in the extension/DLCI table.
Chapter 4. Applications When the called unit goes off-hook, the data link is established and remains up until one of the two extensions terminates the call. Figure 4-7. Switched Mode Application Voice Over Frame Relay Application Voice over frame relay can be accomplished using the Express 5200 with an optional dual voice card installed (Dual FXO, FXS, or E&M card).
Chapter 4. Applications Figure 4-8. Voice Over Frame Relay 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 4-9.
Chapter 4. Applications Figure 4-9. 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 5200 is transparent to the telephone circuit.

Chapter 7. Voice Interface Configuration 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 section Switched Mode Application on page 4-12 for an example application.
Chapter 7. Voice Interface Configuration Selections Available for a Unit in Direct Mode For DIRECT connections, the DLCI for voice traffic must be specified. This information must be specified in both the local and remote units. Voice data may be multiplexed with data on the same DLCI. Line 1 DLCI (L1 DLCI) Local DLCI that Line 1 voice data is carried on. Line 2 DLCI (L2 DLCI) Local DLCI that Line 2 voice data is carried on.

Chapter 10 IP Routing IP ROUTING WITH THE EXPRESS 5200 The Express 5200 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 10. IP Routing In addition to RIP, the network port uses inverse ARP (RFC 1490) to associate peer router/FRAD IP addresses to PVC addresses. The Express 5200 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.
