Chapter 1 Introduction PRODUCT OVERVIEW The ADTRAN TSU IQ+ provides the visibility and control needed for both the physical and logical connections made in frame relay networks. The TSU IQ+ provides logical layer monitoring and management for frame relay. Each permanent virtual circuit (PVC) accessed through a TSU IQ+ is managed end-to-end as if it were a leased-line connection.
Chapter 1.
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 T1/FT1 OVERVIEW The telephone companies (telcos) have used T1 digital communications links for voice transmission since the early sixties. The D4 channel bank is an example of a T1 digital carrier system that was introduced in the mid-seventies and is still widely used by the telcos. Communication demands of businesses continued to grow to the point that the telcos began offering T1 service directly to the public.
Chapter 1. Introduction FT1 remains almost exclusively an inter-exchange carrier (IXC) service. Local exchange carriers (LECs) typically do not offer FT1, so the user's proximity to the IXC's point-of-presence (POP) is key in the savings that fractional T1 offers. SNMP MANAGEMENT SNMP management capability is provided in-band with support for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), RFC 1406 (DS1/E1 MIB), and ADTRAN Enterprise MIB.
Chapter 1. Introduction TELNET Telnet provides a password-protected, remote login facility to the TSU IQ+. Telnet allows a user on a network manager to control the TSU IQ+ through the terminal menus. DIAL BACKUP OPERATION The TSU IQ+ dial backup (DBU) option cards provide single or multiple sight backup, depending on the DBU card option selected. The TSU IQ+ can be configured to originate a call based on physical layer conditions (i.e., port failures) and/or PVC outages.
Chapter 1. Introduction 4-Wire Switched 56 DBU Card This dial-up 4-wire SW56 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. The 4-wire SW56 DBU card is compatible with AT&T Accunet and Sprint SW56 type services. V.34 DBU Card The V.34 DBU card provides switched backup of the leased line application. This module allows backup data rates of up to 33.
Chapter 1.
Chapter 2 Installation UNPACK, INSPECT, POWER UP Receipt Inspection Carefully inspect the TSU IQ+ for any shipping damage. If damage is suspected, file a claim immediately with the carrier and contact ADTRAN Customer Service (see back page for more information). If possible, keep the original shipping container for use in shipping the TSU IQ+ for repair or for verification of damage during shipment.
Chapter 2. Installation The following items are included in ADTRAN shipments of DBU cards: • DBU card • An 8-position modular to 8-position modular cable for the 4-wire SW56, ISDN, or PRI DBU options or an 8-position modular to 4-position modular cable for the V.34 DBU option Customer Provides The customer must provide a male V.35 interface cable.

Chapter 4 Applications This chapter provides examples of some common TSU IQ+ 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 inband 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 fully accessible for configuration, diagnostics, and statistics viewing. Figure 4-1 shows an example of a VT-100 application. 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 TSU IQ+ can be managed through an established Telnet session or an SNMP-based network manager like HP OpenView®, IBM Netview®, or SunNet Manager®. The ADTRAN TSU IQ+ MIB is available in the support section of the ADTRAN Web page at www.adtran.com.
Chapter 4. Applications Minimum 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. IP Address Enter the TSU IQ+ IP address. Control Port Options If necessary, select SLIP or PPP as the TSU IQ+ CONTROL PORT OPTIONS.

Chapter 4. Applications A TSU IQ+ with multiple PVCs to multiple sites can also originate a call to one site during an outage and restore connection for PVCs to that destination. With all DBU cards except for the PRI card, you can make only one call at a time. The other PVCs to other sites in this scenario will be inactive. If you have a PRI card you can originate or answer up to 23 calls. Information entered into the PVC CONFIGURATION table (see Table 4-2 on page 4-13) marks PVCs for DBU operation.
Chapter 4. Applications DBU Application 1(non-PRI) The following application shows the critical configuration required for a case where all end points of the frame circuit are equipped with single call DBU units (see Figure 4-6). This set-up allows any remote site to place a call to the host site or the host site to place a call to each remote site based on PVC failure.

Chapter 4. Applications DBU Application 2 (PRI) The following application shows the critical configuration for a case where the Host Site of the frame relay circuit is set up to restore service (see Figure 4-7). This setup uses a PRI ISDN module and service so that multiple calls can be placed simultaneously. The criteria for placing a call are based on Host Site port failure or individual PVC failure. The individual PVC failure should account for remote sites port outages and frame relay service troubles.

Appendix C.
Appendix D Glossary AIS alarm indication signal. A signal transmitted instead of the normal signal to maintain continuity of transmission. The AIS indicates to the far end the existence and direction of the transmission fault on the line. ANSI American National Standards Institute. Devices and proposes recommendations for international communications standards. ASCII American National Standard Code for Information Interchange.
Appendix D. Glossary bandwidth The bandwidth determines the rate at which information can be sent through a channel (the greater the bandwidth, the more information that can be sent in a given amount of time). BECN backward explicit congestion notification. A bit set by a frame relay network to notify an interface device (DTE) that congestion avoidance procedures should be initiated by the sending device. BES bursty errored second. A second in which between 2 and 319 CVs (code violations) occurred.
Appendix D. Glossary bridge A device that supports LAN-to-LAN communications. Bridges may be equipped to provide frame relay support to the LAN devices they serve. A frame relay capable bridge encapsulates LAN frames in frame relay frames and feeds them to a frame relay switch for transmission across the network. A frame relay capable bridge also receives frame relay frames from the network, strips the frame relay frame off each LAN frame, and passes the LAN frame on to the end device.
Appendix D. Glossary 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. The clock has two functions: (1) to generate periodic signals for synchronization and (2) to provide a time base. code violation See CV. control port The electrical interface between the TSU IQ+ unit and a control terminal. The control terminal is used to communicate commands to the unit.
Appendix D. Glossary CTS clear to send. A signal on the DTE interface indicating that the DCE is clear to send data. CV code violation. Cyclic redundancy check (CRC) errors and frame bit errors when in ESF (extended super frame) format, or bipolar violations and frame bit errors when in SF (super frame) format. data link See FDL. 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.
Appendix D. Glossary DLCI data link connection identifier. A unique number assigned to a PVC end point in a frame relay network. Identifies a particular PVC endpoint within a user's access channel in a frame relay network and has local significance only to that channel. DSU data service unit. A device designed to transmit and receive digital data on digital transmission facilities. DTE data terminal equipment.
Appendix D. Glossary far end The unit or units not on-site (at the customer's premises or the other end of the T1 link). FCS frame check sequence. The standard 16-bit cyclic redundancy check used for HDLC and frame relay frames. The FCS detects bit errors occurring in the bits of the frame between the opening flag and the FCS, and is only effective in detecting errors in frames no larger than 4096 octets. See also CRC. FDL facility data link. A 4 kbps data channel provided by 12 of the ESF framing bits.
Appendix D. Glossary framing A control procedure used with multiplexed digital channels (such as T1 carriers) where bits are inserted so the receiver can identify time slots allocated to each subchannel. Framing bits may also carry alarm signals indicating specific alarm conditions, cyclic redundancy checks (CRCs), and an out-of-band data channel in the case of an extended superframe (ESF) T1 link. In T1 terminology, a frame consists of 192 data bits and one framing bit.
Appendix D. Glossary 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. Interworking with a public switched telephone network is retained. LAN local area network.
Appendix D. Glossary near end The unit on-site. network interface (NI) The point of interconnection between the TSU IQ+ unit and the carrier's T1 network. out-of-band Signaling that is separated from the channel carrying information (voice, data, video, etc.). Typically the separation is accomplished by a filter. The signaling includes dialing and other supervisory signals. packet A message containing both control information and data.
Appendix D. Glossary 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 service The provision of telecommunications to customers by a common carrier, administration, or private operating agency using voice, data, and/or video technologies. SES severely errored second. A second in which more than 319 code violations (CVs) occurred or an OOF condition occurred. SF See superframe. SNA systems network architecture. The IBM protocol group which governs mainframe communication. SNMP simple network management protocol.
Appendix D. 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. T1 A digital transmission link with a capacity of 1.544 Mbps. T1 uses two pairs of normal twisted wires.
