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.

Chapter 1. Introduction

Chapter 1

Introduction

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

61200.130L1-1 FSU User Manual 1

Chapter 1. Introduction

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 FSU provides a low cost solution for the CPE equipment in a private or public frame relay network. The FSU connects to the frame relay network via 56/64k DDS (digital data service) or T1/FT1 access links. Connections to 56/64k DDS are made using an integral 56/64k DSU or an external DSU. T1/FT1 connections are made using an external T1 DSU/CSU through a V.35 interface.

The FSU provides connections to the user equipment through two independent ports emulating a DCE device. These ports can be configured for either RS-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 handles each frame of the user data in a three-step 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.

The major features of the FSU are as follows:

• Two DTE (data terminal equipment) ports for use on a single frame relay network interface.

• Support for IP (internet protocol), SDLC (synchronous data link control), Bisync, SLIP (serial link IP), PPP (point-to-point protocol) both sync and async, frame relay, BOP (bit-oriented protocol), and async protocols.

• SNMP (simple network management protocol) management capability provided inband with support for RFC 1315 (frame

2 FSU User Manual 61200.130L1-1

relay DTE MIB), RFC 1213 (MIB II), and ADTRAN Enterprise MIB.

• DCE port supporting rates of up to 512 kbps.

• Optional integrated 56/64 DDS DSU/CSU.

• Telnet-provided remote terminal management control.

• FLASH code space for easy software upgrades.

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. With the optional integrated 56/64 DDS DSU, the FSU supports the 56/64 kbps DDS service rate yielding DTE rates of 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 kbps.

56/64K DDS DSU OPTION

The FSU is available with an optional integrated 56/64k DSU (part number 1200130L2). This gives the unit the ability to directly connect to a frame relay network via a 56 or 64k DDS circuit.

Chapter 1. Introduction

SNMP MANAGEMENT

SNMP management capability is provided inband with support for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), and ADTRAN Enterprise MIB. Telnet capability is also supported. For non-SNMP environments, VT 100 and front panel operation is supported.

20 FSU User Manual 61200.130L1-1

This chapter provides examples of some common FSU applications. The examples include SNA/SDLC with local spoofing, SNMP/Telnet management, bisync point-to-point and multipoint, and transparent applications. 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 provides local spoofing by emulating the primary or secondary SDLC roles (see Figure 4-1). The FSU performs conversion from SDLC to frame relay and also terminates SDLC links, providing primary and secondary emulation between FSUs. Local spoofing improves performance by reducing traffic across the frame relay network and allows definite response times on the SDLC links.

Chapter 4. Applications

Chapter 4

Applications

To perform spoofing, the FSU 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 looks for SNRM on all ports and assumes a secondary role once SNRM is received. The FSU then brings up the LLC2 link across the frame relay network to another FRAD which assumes a primary role. This allows the FSU to operate with PU 2.1 devices.

Different roles can be assumed for each SDLC session. Disconnection starts the role determination procedure again.

61200.130L1-1 FSU User Manual 21

Chapter 4. Applications

In all cases, the FSU is transparent to the XID (exchange identification) negotiation between any two network devices.

The FSU 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 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 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 routes data at the DLCI level using the DTE 2 frame relay address table. The FSU 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. This Management DLCI carries the SNMP and telnet traffic destined for the FSU. This DLCI is included in the UNI full status responses to the router. The FSU 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's SNMP and telnet information. See Table 4-B for an example configuration.

RIP and inverse ARP are not used for the FSU DTE frame relay port.

Bisync Application

The FSU 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 performs local spoofing, minimizing traffic across the frame relay network. Sample network illustrations for both point-topoint and multi-point are shown in Figures 4-3 and 4-4.

See Table 4-C for an example configuration for the point-to-point application.

Chapter 4. Applications

Transparent Application

In cases when the user protocol is not supported by the FSU, the transparent mode may be used. Transparent bit-oriented protocol (BOP) or transparent asynchronous protocol may be selected. This can be used for point-to-point connections only because the FSU is transparent to the protocol address formats.

In the transparent BOP protocol, the FSU 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 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 buffers async characters and encapsulates the data portion of each character for transport across frame relay using a programmable DLCI and remote FSU 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.

61200.130L1-1 FSU User Manual 33

Chapter 5. Configuration Overview

The FSU contains a default set of configuration options stored in read-only memory (see the appendix Default Configuration Profile). 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. When the profile is modified, it is stored in the current (nonvolatile configuration) memory. The FSU is then configured with that profile every time power is turned on.

For detailed information on configuration see the chapters DTE

Port Configuration, Network Port Configuration, IP Routing, and System Configuration.

Configuration menus are shown in Figures 5-2 (for the Front Panel) and 5-3 (for the VT 100 terminal).

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 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.

Protocol Options

Signaling Type (SIGNAL)

Set the signaling type for the DTE port to match the signaling type of the connected DTE device. Choices are none, FRF 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 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, set the Management DLCI to a unique value that identifies the virtual circuit between the router/FRAD and the FSU. The router/FRAD must also be configured to route the FSU IP address to this DLCI. The IP address and subnet mask for the DTE port must also be set.

44 FSU User Manual 61200.130L1-1

Chapter 6. DTE Port Configuration

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 ADDR)

Enter the FSU IP address. Each port capable of carrying IP traffic has its own unique IP address. See the previous section, Guide- lines for Configuring IP Addr, Subnet Mask, and Mng DLCI, for more information.

IP Subnet Mask

Enter the subnet number assigned to the network formed by the FSU and the other FRAD/routers across the frame relay network. See the section, Guidelines for Configuring IP Addr, IP 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 to carry SNMP and telnet packets to/ from the FSU on the DTE port. See the section, Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI, for more information.

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 FSUs 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.

Configuring the Network Port

Access the Network Port menus by selecting Network Port from the Configuration menu. See the menu tree in Figure 7-1. 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 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.

Connection

Connection is made through the internal DDS 56/64 DSU (if installed). If this option is not installed, use an external DDS or fractional T1 (up to 512 kbps) DSU.

)

When connecting to an external DSU, the FSU emulates an externally timed DTE interface connected directly to the DCE interface of the external device. Therefore, the connection between the FSU and the DSU is a direct connection.

Signaling Type (SIGNAL)

Set the signaling type option to match the network signaling type.

T391

Set the time between polls to the frame relay network.

N391

Determine how many link integrity polls occur in between full status polls.

N392 and N393

These parameters define the error threshold for the UNI formed by the FSU 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 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 FSUs and can only be used with an ADTRAN FSU on both ends of the virtual circuit.

The network service provider should recommend the values entered into the T391, N391, N392, and N393 fields.

IP ROUTING WITH THE FSU

The FSU 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. The automatic method cuts down on manual entry for large route tables and allows for routes to be changed without service interruption.

Chapter 8. IP Routing

Chapter 8

IP Routing

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

61200.130L1-1 FSU User Manual 77

Chapter 8. IP Routing

The FSU 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 8-1 will appear. Full menu trees for these selections are shown in Figures 5-2 (Front Panel Configuration Menu Tree) and 5-3 (VT 100 Configuration Menu Tree).

IP Route Table

Chapter 8. IP Routing

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 8-2.

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.
