  • Page 65: Trap Manager Ip Address

    YSTEM PTIONS In-Band Management The ADTRAN TSU IQ+ supports three modes of in-band management using the frame relay structure of PVCs. These modes are local, shared, and dedicated PVC management. All three types support complete SNMP management as well as Telnet capabilities.

  • Page 66: Minimum Configuration Requirements For Local Pvc Management

    Chapter 4. Applications Local PVC management can be used at any location that has a router. Therefore, remote sites can be accessed through the remote router. One consideration when using local PVC management is that if the remote router goes down, access to the remote TSU is lost.

  • Page 67: Write Community

    PVC must be RFC 1490 encapsulated, noncompressed IP traffic. Shared PVC management is used to manage remote TSU IQ+s without being dependent on services from the remote router. This usually requires a static route at the host location.

  • Page 179 Glossary Appendix D alarm indication signal. A signal transmitted instead of the normal signal to maintain continuity of transmission. The AIS indicates to the far end the exist- ence and direction of the transmission fault on the line. ANSI American National Standards Institute. Devices and proposes recommenda- tions for international communications standards.

    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.
  • Page 181 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.
  • Page 182 Appendix D. Glossary clocking An oscillator-generated signal that provides a timing reference for a transmis- sion 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.
  • Page 183 Appendix D. Glossary clear to send. A signal on the DTE interface indicating that the DCE is clear to send data. 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.
  • Page 184 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.
  • Page 185 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). 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 detect- ing errors in frames no larger than 4096 octets.
  • Page 186 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.
  • Page 187 Appendix D. Glossary ISDN integrated services digital network. A network architecture that enables end-to- end digital connections. The network supports diverse services through inte- grated access arrangements and defines a limited set of standard, multipurpose interfaces for equipment vendors, network providers, and customers. Inter- working with a public switched telephone network is retained.
  • Page 188 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 net- work. 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.
  • Page 189 A red alarm is declared on detection of an LOS or OOF not caused by an alarm indication signal (AIS) that persists for two seconds. remote configuration A feature designed into ADTRAN products that allows remote units to be con- figured from a local unit or VT 100 compatible terminal. router A device that supports LAN-to-LAN communications.
  • Page 190 Appendix D. Glossary service The provision of telecommunications to customers by a common carrier, admin- istration, or private operating agency using voice, data, and/or video technolo- gies. severely errored second. A second in which more than 319 code violations (CVs) occurred or an OOF condition occurred.
  • Page 191 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 informa- tion sent along with the transmitted data.
