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 • Control port provides SLIP and async PPP access to SNMP or VT-100 terminal configuration • Dial backup (DBU) available with DBU cards; options include 4-wire Switched 56 (SW56), V.
Chapter 1. Introduction 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. This DLCI is valid until the call is disconnected and may be assigned a different value each time a call is requested.
Chapter 1. Introduction TELNET Telnet provides a password-protected, remote log-in facility to the IQ Probe. Telnet allows a user on a network manager to control the IQ Probe through the terminal menus. DIAL BACKUP OPERATION The IQ Probe dial backup (DBU) option cards provide single or multiple site backup. The IQ Probe can be configured to originate a call based on physical layer conditions (i.e., port failures) and/or PVC outages.
Chapter 1. Introduction INTERFACE CARD OPTIONS 4-Wire Switched 56 DBU Card This dial-up 4-wire SW56 DBU 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. This card is compatible with AT&T Accunet and Sprint SW56 type services. 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.

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 VT-100 remote mode is proprietary and non-intrusive. Therefore, you can perform all VT-100 management functions without disrupting the flow of data.
Chapter 4. Applications 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. The IQ Probe can be managed though an established Telnet session or an SNMP-based network manager like HP OpenView , IBM Netview , or SunNet Manager . ¨ ¨ ¨ The ADTRAN IQ Probe MIB is available in the support section of the ADTRAN Web page at www.adtran.com.
Chapter 4. Applications Minimum System Configuration Requirements The following options (all found in the SYSTEM portion of the CONFIGURATION menu) are the minimum configuration requirements for establishing out-of-band SNMP or Telnet access. Once these options are configured, the unit may be accessed using SNMP/Telnet. Control Port Mode If necessary, select SLIP or PPP as the IQ Probe control port mode. If ethernet is the interface type, this parameter does not affect setup.
Chapter 4. Applications 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. Trap Manager Port Enter the IQ Probe port used to transmit traps to the SNMP manager. This selection is found under TRAP MGR OPTIONS in the SYSTEM portion of the C ONFIGURATION menu. You may assign up to five possible trap destinations in the TRAP MGR OPTIONS table.
Chapter 4. Applications sponds to Inverse ARP, it is not necessary to set up a static route in the router. The router will discover the IP address automatically; however, it will be necessary to set up a local PVC between the router and the IQ Probe. Accomplish this by setting a value (between 16 and 1007) for the DTE management DLCI on the IQ Probe to a value not used by the frame relay network. Local PVC management can be used at any location that has a router.
Chapter 4. Applications Management DLCI Enter a DLCI number (between 16 and 1007) that is not used by the frame relay service. This option is found in the FRAME R ELAY OPTIONS portion of the DTE PORT CONFIGURATION menu. The next five settings are applicable for SNMP access only. Read Community Set the R EAD COMMUNITY name to match the NMS settings. Write Community Set the W RITE COMMUNITY name to match the NMS settings.
Chapter 4. Applications Shared PVC management is used to manage remote ADTRAN IQ devices without being dependent on services from the remote router. This usually requires a static route at the host location. By setting a local PVC management and shared PVC management on the remote IQ Probe, its IP address can be found through Inverse ARP. 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 Management DLCI 1 and/or DLCI 2 Enter the management DLCI(s) used to carry management traffic to and from the network. This option is found in the DCE PORT C ONFIGURATION menu. Management DLCI 1 and/or DLCI 2 Mode Set to DEDICATED if the management DLCI is used only to manage the IQ Probe (and not used to carry customer traffic). If set to DEDICATED, the router is not notified of that DLCI. Set to SHARED if the DLCI is used to carry customer traffic as well as management data.
Chapter 4. Applications You may assign up to five possible trap destinations in the TRAP MGR OPTIONS table. Dedicated PVC Management Dedicated PVC management refers to the ability to have a PVC originated from the network and terminated in the IQ Probe. This is an ideal configuration for third-party management. It isolates the customer’s data traffic from network management traffic, and it also acts as a fire-wall that restricts management data to the IQ Probe.
Chapter 4. Applications DIAL BACKUP APPLICATION The IQ Probe dial backup (DBU) option cards provide single site backup. The IQ Probe can be configured to originate a call based on physical layer conditions (i.e., port failures) and/or PVC outages. Once the criteria are met, the IQ Probe establishes a call to the configured phone number (see Table 4-1 on page 4-12) and the connection is used to carry traffic for the PVC(s) configured for DBU operation.
Chapter 4. Applications Dial Backup Example Application Figure 4-6 shows an example of a dial backup application. The configuration selections given may need modification based on your network configuration.

Chapter 6. DTE Port Configuration None No flow control is used and the IQ Probe drops frames during severe congestion while in dial backup operation. Hardware The IQ Probe varies the DTE TC clock as necessary to relieve congestion during dial backup operation. FECN/BECN While in a congested state during dial backup operation, frames across the DBU PVCs have FECN or BECN set depending on the direction.
Chapter 6. DTE Port Configuration 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 Signaling Responses (SIG RESPONSES) This option determines when PVC signaling responses are sent to the router. Always On If ENABLED, PVC signaling responses are sent to the router regardless of the network signaling state. Enable this option when the IQ Probe is used for dial backup. Follows Network (FOLLOW NET) If ENABLED, PVC signaling responses are sent to the router only when the network signaling state is up.
Configuring the DCE Port Chapter 7 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 on the enclosed insert. The DCE port terminates the user end of the frame relay UNI interface. The IQ Probe supports three standard PVC signaling formats: LMI (gang of four), ANSI T1.617-D (Annex D), and ITU Q.933-A (Annex A).
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, EIA-530, and EIA-232. Serial Bit Rate (RATE ) Set the SERIAL BIT R ATE 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 N ONE, 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 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 errorfree 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.
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 DLCI Enter the DCE port's DLCI. Range is 16 to 1007. DBU DLCI Enter the far end DLCI for each PVC used for dial backup. Only the IQ Probe that originates the call is required to have this option set. Range is 16 to 1007. DBU Phone Number The phone number entry stores the phone number that is used when the IQ Probe triggers auto dial backup in case of port or PVC failure.
Chapter 7. Configuring the DCE Port DBU Call Order Number This determines the order in which a list of backup locations will be dialed. This applies only to auto DBU processes that are triggered by port failure. If all DBU CALL ORDER entries are set to NONE, then the first entry with a DBU PHONE NUMBER will be used. CIR (Kbps) Enter the CIR in kbps for the corresponding DLCI. The information is supplied by your service provider and must be entered for each PVC to ensure accuracy of statistical information.
Chapter 7. Configuring the DCE Port Disabled If set to DISABLED, then statistics will not be logged for this PVC at any time. If the IQ Probe encounters a PVC that has not been entered into the PVC OPTIONS table, the PVC is set to AUTO by default. Next (NEXT key on front panel) Edit the next entry in the PVC O PTIONS table. Previous (PREV key on front panel) Edit the previous entry in the PVC OPTIONS table. Add (ADD key on front panel) Add a new entry to the PVC OPTIONS table.

Appendix C.
Appendix D Glossary ANSI American National Standards Institute. Devises 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.
Appendix D. 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.
Appendix D. Glossary performs multiplexing of lower speed digital channels into a higher speed composite channel. The channel bank also detects and transmits signalling information for each channel; thereby transmitting framing information so that time slots allocated to each channel can be identified by the receiver. 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.
Appendix D. Glossary CRC Cyclic redundancy check. A computational means to ensure the accuracy of frames transmitted between devices in a frame relay network. The mathematical function is computed, before the frame is transmitted, at the originating device. Its numerical value is computed based on the content of the frame. This value is compared with a recomputed value of the function at the destination device. CS See CTS. CSU Channel service unit.
Appendix D. Glossary DDS Digital data service. AT&T private line service for transmitting data over a digital system. The digital transmission system transmits electrical signals directly, instead of translating the signals into tone of varied frequencies as with traditional analog transmission systems. Digital techniques provide more efficient use of transmission facilities, resulting in lower error rates and costs than analog systems. DE Discard eligibility.
Appendix D. Glossary end device The ultimate source or destination of data flowing through a frame relay network sometimes referred to as DTE. As a source device, it sends data to an interface device for encapsulation in a frame relay frame. As a destination device, it receives de-encapsulated data (i.e., the frame relay frame is stripped off, leaving only the user's data) from the interface device. far end The unit or units not on-site (at the customer's premises or the other end of the data link).
Appendix D. Glossary gateway A device which enables information to be exchanged between two dissimilar systems or networks. HDLC High level data link control. A generic link-level communications protocol developed by the International Organization for Standardization (ISO). HDLC manages synchronous code-transparent, serial information transfer over a link connection. See also SDLC. host computer The primary or controlling computer in a multiple computer operation.
Appendix D. Glossary LAN Local area network. A privately owned network that offers highspeed communications channels to connect information processing equipment in a limited geographic area. MIB Management information base. A database of network management information used by SNMP. modem The equipment that connects DTE to an analog (voice) communications. near end The unit on-site. network interface (NI) The point of interconnection between the IQ Probe unit and the carrier's frame relay network.
Appendix D. Glossary ping An internet protocol standard that provides loopback on demand for any device in an IP network. One device "pings" another by sending a loopback request to the device's IP address. point-to-point Type of communications link that connects a single device to another single device, such as a remote terminal to a host computer. PVC Permanent virtual circuit. A frame relay logical link, whose endpoints and class of service are defined by network management. Analogous to an X.
Appendix D. Glossary SDLC Synchronous data link control. A link-level communications protocol used in an IBM systems network architecture (SNA) network that manages synchronous, code-transparent, serial information transfer over a link connection. SDLC is a subset of the HDLC protocol developed by ISO. service The provision of telecommunications to customers by a common carrier, administration, or private operating agency using voice, data, and/or video technologies. SNA Systems network architecture.
Appendix D. Glossary 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. transmission The dispatching of a signal, message, or other form of intelligence by wire, radio, telegraphy, telephony, facsimile, or other means.
