Chapter 1. Introduction Chapter 1 Introduction PRODUCT OVERVIEW The ADTRAN IQ Probe provides the visibility and control needed for both the physical and logical connections made in frame relay networks. The IQ Probe provides logical layer monitoring and management for frame relay. Each permanent virtual circuit (PVC) accessed through an IQ Probe is managed end-to-end as if it were a leased line connection.
Chapter 1. Introduction information rates (CIRs), and excess burst rates on each PVC • True non-intrusive, in-band transmission of statistics • Embedded SNMP and TELNET through the DTE, DCE, or SLIP/PPP port • Embedded SNMP and TELNET access available through the integrated 10baseT ethernet port • Control port provides SLIP and async PPP access to SNMP or VT 100 terminal configuration • Dial backup (DBU) available with ESP DBU cards; options include 4-wire Switched 56 (SW56), V.
Chapter 1. Introduction 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.

Chapter 4. Applications Chapter 4 Applications This chapter provides examples of some common IQ Probe management options as well as an example of a dial backup application. The management application examples include VT 100 management, out-of-band SNMP/TELNET management, and in-band PVC SNMP/TELNET management. Descriptions and configuration tips for these options are provided in the sections that follow. The application drawings in this chapter show routers as the frame relay device.
Chapter 4. Applications Local VT 100 Terminal Management Connect a VT 100 terminal to the IQ Probe CONTROL port. This interface provides full-screen configuration and all-inclusive statistics access. VT 100 management also allows for remote configuration. Through this port, a remotely located ADTRAN IQ device is fully accessible for configuration, diagnostics, and statistics viewing. Figure 4-1 gives an example of a VT 100 application. VT 100 remote mode is proprietary and non-intrusive.
Chapter 4. Applications Control Port Mode Set the Control Port Mode for TERMINAL (which is the default setting). This selection is found in the SYSTEM portion of the CONFIGURATION menu (SYSTEM -> CONTROL PORT OPTIONS -> CONTROL PORT MODE). Out-of-Band Management This management option (shown in Figure 4-2) is commonly used in situations where the customer is trying to reduce the amount of management traffic flowing through the frame relay device.
Chapter 4.
Chapter 4. Applications Gateway IP Address (if required) Enter the Gateway node IP address. This address is applicable only if the IQ Probe and the network manager are connected through a Gateway node. This address is available from the network administrator. The next five settings are applicable for SNMP access only: Read Community Set the Read Community name to match the NMS (network management system) settings. Write Community Set the Write Community name to match the NMS settings.
Chapter 4. Applications All PVC-based in-band management traffic must be noncompressed IP and use RFC 1490 encapsulation. Local PVC Management Local PVC management refers to a PVC created between the IQ Probe and the frame relay router on the DTE interface of the IQ Probe. This type of management is ideal when local management is needed but an ethernet connection is not available. To support this type of management, all traffic on the selected PVC must be RFC 1490 encapsulated, noncompressed IP traffic.
Chapter 4.
Chapter 4. Applications Write Community Set the Write Community name to match the NMS settings. Trap Manager DLCI Identify the virtual circuit used for all traps generated by the IQ Probe. This selection is found under TRAP MGR OPTIONS in the SYSTEM portion of the CONFIGURATION menu. Trap Manager IP Address Enter the IP address of the SNMP manager to which the IQ Probe sends traps. This selection is found under TRAP MGR OPTIONS in the SYSTEM portion of the CONFIGURATION menu.
Chapter 4. Applications Since the unit is set up for shared PVC management, all management traffic will be intercepted prior to reaching the remote router.
Chapter 4. Applications SHARED if the DLCI is used to carry customer traffic as well as management data. This option is found in the DCE Port Configuration menu. The IQ Probe unit supports management from two network DLCIs either shared or dedicated. The next five settings are applicable for SNMP access only: Read Community Set the Read Community name to match the NMS settings. Write Community Set the Write Community name to match the NMS settings.
Chapter 4. Applications traffic, and it also acts as a fire-wall that restricts management data to the IQ Probe. Dedicated PVC management is also ideal when the user wants to guarantee access to a remote IQ Probe regardless of the state of the remote LAN.
Chapter 4. Applications During dial backup, the IQ device receiving the call continues to use the frame relay circuit for PVCs that are not affected by the outage, while using the DBU interface for PVCs that are inactive due to the outage. This is done (without the attached DTE device's intervention) by modifying the status of PVCs that are in DBU state to active when the PVC status is given to the DTE.
Chapter 4. Applications See Figure 4-6 for an example of a dial backup application. Tables 4-A and 4-B provide example setups for the DBU Options (CONFIG ->DIAL BACKUP) and the PVC Configuration Table (CONFIG ->DCE PORT ->PVC CONFIG). The tables are based on the example application shown in Figure 4-6. Please note that the configuration selections given may need modification based on your network configuration.

Chapter 6. DTE Port Configuration Chapter 6 DTE Port Configuration Configure the physical layer and frame relay protocol options for the DTE port located on the rear of the IQ Probe by selecting DTE PORT from the Configuration menu. Figure 6-1 illustrates the terminal Configuration menu for the DTE Port. The menu tree in Figure 6-2 shows the choices available in this menu.
Chapter 6. DTE Port Configuration In this chapter, the terminal selections are listed first followed by the Front Panel selections in parenthesis (if the names differ). 1 INTERFACE TYPE 2 FLOW CONTROL 1 X.21 2 V.
Chapter 6. DTE Port Configuration None No flow control is used and the IQ Probe drops frames during severe congestion while in DBU operation. Hardware The IQ Probe varies the DTE TC clock as necessary to relieve congestion during DBU operation. FECN/BECN While in a congested state during DBU operation, frames across the DBU PVCs have FECN or BECN set depending on the direction. Frames outbound to the network have FECN set, while frames inbound to the attached DTE device have BECN set.
Chapter 6. DTE Port Configuration Forced On The CD lead is always on. Normal The CD lead is off when the IQ Probe does not receive CD from the DSU/CSU on the DCE port. TC Clock Option (TC CLOCK OPT) Normal Clock for DTE's transmit data normal phase. Inverted Clock for DTE's transmit data inverted phase. May be used in high speed circuits (>512 kbps) when the DTE's V.35 interface has high delay. This is usually indicated by HDLC errors on the IQ Probe's DTE port.
Chapter 6. DTE Port Configuration 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. Management DLCI (MGMT DLCI) To use local PVC management, enter the management data link connection identifier (DLCI).
Chapter 6. DTE Port Configuration Follows Network (FOLLOW NET) If ENABLED, PVC signaling responses are sent to the router only when the network signaling state is up. Enable this option when the router is going to use an alternate path for dial backup.
Chapter 7. Configuring the DCE Port Chapter 7 Configuring the DCE Port DCE PORT Access the DCE port menus by selecting DCE PORT from the Configuration menu. Full menu trees for the DCE Configuration selections are shown in Figures 5-2 (Terminal Configuration Menu Tree) and 5-3 (Front Panel Configuration Menu Tree) of the Configuration Overview chapter. The DCE port terminates the user end of the frame relay UNI interface.
Chapter 7. Configuring the DCE Port Figure 7-1 Terminal DCE Port Configuration Menu Physical Layer Options (PHYS LYR OPTS) The following sections describe the physical layer options available for the DCE port: Interface Type Select the DCE interface type. The choices are X.21, V.35, EIA530, and EIA-232. Serial Bit Rate (RATE ) Set the Serial Bit Rate to match the speed of the attached DSU/ CSU. The IQ Probe uses this information for statistical analysis.
Chapter 7. Configuring the DCE Port Frame Relay Options (FR OPTS) The terminal screen in Figure 7-2 appears when Frame Relay Options is selected from the DCE Port Configuration Menu. Figure 7-2 Terminal DCE Port Frame Relay Options Menu Signaling Type (SIGNAL) Set the signaling type option to match the DCE signaling type. Choices are none, LMI (gang of four), ANSI T1.617-D (Annex D), ITU-T Q.933-A (Annex A), or auto.
Chapter 7. Configuring the DCE Port 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 IQ Probe DCE 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.
Chapter 7. Configuring the DCE Port Maximum PVC Count (MAX PVC COUNT) Sets the maximum number of PVCs that the IQ Probe will monitor for statistical information. This value determines the amount of history intervals available for storage. To get the maximum amount of statistical history storage, set this value equal to the number of PVCs assigned to the frame relay port. A smaller value increases history interval count but puts some of the PVC statistics into the unknown category.
Chapter 7. Configuring the DCE Port Only PVCs that are used in DBU should have the DBU DLCI set to a non-zero value. The range for the DBU DLCI field is from 16-1007. Therefore, you cannot manually enter 0 for the PVCs not used in DBU. When an entry is first created with the ADD selection, it is set to 0 by default. To reset a previously configured DBU DLCI to 0, delete the entry and then add it back in (using the Delete and Add selections/keys).

Glossary Glossary ANSI American National Standards Institute. Devices and proposes recommendations for international communications standards. ASCII American National Standard Code for Information Interchange. The standard and predominant 7-bit (8-bit with parity) character code used for data communications and data processing. asynchronous A method of data transmission which allows characters to be sent at irregular intervals by preceding each character with a start bit, followed by a stop bit.
Glossary bit A binary digit. A signal, wave, or state is represented as either a binary 0 or 1. bits per second (bps) The number of bits passing a specific point per second. Examples of common rates are: • A Kilobit is one thousand bits per second (kbps) • A Megabit is one million bits per second (Mbps) bridge A device that supports LAN-to-LAN communications. Bridges may be equipped to provide frame relay support to the LAN devices they serve.
Glossary CIR committed information rate. Less than or equal to the access rate, the CIR is used by the service provider for rate enforcement when the network is congested. When rates exceed the CIR, frames may be discarded. clocking An oscillator-generated signal that provides a timing reference for a transmission link. A clock provides signals used in a transmission system to control the timing of certain functions.
Glossary 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. dB The standard abbreviation for decibel. A decibel is a unit of measure for signal. A decibel is usually the relation between a transmitted signal and a standard signal source.
Glossary DSU data service unit. A device designed to transmit and receive digital data on digital transmission facilities. 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.
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.
Glossary IP internet protocol. A protocol which provides for transmitting blocks of data between hosts identified by fixed-length addresses. 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.
Glossary packet-switching network A telecommunications network based on packet-switching technology, wherein a transmission channel is occupied only for the duration of the transmission of the packet. Contrast with frame relay network. parameter A numerical code that controls an aspect of terminal and/or network operation. Parameters control such aspects as page size, data transmission speed, and timing options.
Glossary strips the frame relay frame off of each frame to produce the original LAN frame, and passes the LAN frame on to the end device. Routers connect multiple LAN segments to each other or to a WAN. Routers route traffic on the Level 3 LAN protocol (e.g., the internet protocol address). See also bridge. SDLC synchronous data link control.
Glossary synchronizing bits (sync bits) A fixed pattern in synchronous transmission used to identify the boundaries of frames. synchronous Communications in which the timing is achieved by sharing a single clock. Each end of the transmission synchronizes itself with the use of clocks and information sent along with the transmitted data. TELNET The standard TCP/IP remote login protocol specified in RFC-854.
