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 protocol session is established. The CPE equipment must request a call and the DLCI is assigned by the network switching equipment.

61202175L1-1 Express 5200 User Manual 1-1

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.

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

1-4 Express 5200 User Manual 61202175L1-1

FXS Module

FXO Module

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.

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-poin t, 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.

DATA APPLICATIONS SNA/SDLC with Local Spoofing

When used in an SNA/SDLC network, the Express 5200 provides local spoofing by emulating the prim ary or secondary SDLC roles (see Figure 4-1). The Express 5200 performs conversion from SDLC to frame relay and also terminates SDLC links, providing primary and secondary emulation between Express 5200s. 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 Express 5200 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 Express 5200 looks for SNRM on all ports and assumes a secondary role once SNRM is received. The Express 5200 then brings up the LLC2 link across the frame relay network to another FRAD which

61202175L1-1 Express 5200 User Manual 4-1

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. 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 Tab le 4-1 for an example of how to configure the Express 5200 for this application.

Bisync Application

The Express 5200 can be used to connect IBM 3780/2780 (see IBM manual number GA27-3004-2) bisync con trollers and a host across a frame relay network. Point-to-point and mu lti-point configurations are supported at speeds up to 19.2 kbps. The LLC protocol (mode 2) is used to provide a reliable transport layer across the frame relay network. In a multi-point configuration, the Express 5200 performs local spoofing, minimizing traffic across the frame relay network. Sample network illustrations for both point-to-point and multi-point are shown in Figure 4-3 and Figure 4-4.

See Tab le 4-3 for an example configuration of the multi-point application.

Transparent Application

In cases when the user protocol is not supported by the Express 5200, 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 5200 is transparent to the protocol address formats.

In the

RANSPARENT

BOP

protocol, the Express 5200 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 Express 5200 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

SYNC

mode. The Express 5200 buffers async characters and

RANSPARENT

encapsulates the data portion of each character for transport across frame relay using a programmable DLCI and remote Express 5200 port number.

See Figure 4-5 and Tabl e 4- 4 for an example of a transparent BOP configuration. See Figure 4-6 and Table 4-5 for an example of a transpar e n t as ynchronous applica t io n.

VOICE 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-bycall 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.

4-12 Express 5200 User Manual 61202175L1-1

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 5 200 transmits this information to the host Express 5200, 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 Express 5200 terminates the call.

External Call Reception

When an incoming call is received from the PBX, the remote Express 5200 auto-answers the call and generates a dial tone. At this point, the calling party can dial the 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 Express 5200 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 5200 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 Express 5200 is taken off-hook, the remote Express 5200 generates a dial tone and waits for the extension to be entered. 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. If the extension is found in the extension/DLCI table, the call is routed to the appropriate extension via the host unit.

61202175L1-1 Express 5200 User Manual 4-13

Chapter 4. Applications

When the called unit goes off-hook, the data link is establishe d 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). In this configuration, multiple units are daisy-chained at the host site to accommodate up to eight switched OPX (off premise extension) lines. Six lines are shown in Figure 4-8 . The Express 5200 can be daisy-chained on the host end to accommodate more PBX extensions.

4-14 Express 5200 User Manual 61202175L1-1

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

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.

61202175L1-1 Express 5200 User Manual 4-15

Chapter 4. Applications

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. All signalling information is generated/detected by the attached PBX/telephone.

Figure 4-9. PLAR Mode Application

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 4-10.

Chapter 8 Network Port Configuration

NETWORK PORT

Access the network options by selecting

ONFIGURATION

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 Express 5200 supports three standard PVC signaling formats: LMI (gang of four), ANSI T1.617-D (Annex D), and ITU Q.933-A (Annex 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.

Set the time between polls to the frame relay network.

These parameters define the error thr e shold fo r th e UNI formed by the Express 5200 network port and the frame relay switch. If the error threshold is met, the signaling state status is changed to

OWN

, 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.
