  • Page 25: Frx6000 Rlp, Lics, And Cables

    Switch settings assign each RLP in a unique ID within the node. As shown in Figure 1-3, one or two Line Interface Cards (LICs) mount to an RLP and provide electrical interfaces to connectors on the RLP. Each LIC supports four I/O ports, all of the same interface type.

  • Page 26: Lan Adapters

    LAN Adapters The FRX6000 supports LAN (local-area network) interfaces via one or two of these adapters: Ethernet (802.3) – 10baseT (RJ45/twisted pair), 10base2 (BNC/coax), or AUI (DB15/coax) Token Ring (802.5) – RJ45 (twisted pair) or DB9 Depending on the number of RLPs, an FRX6000 can contain one or two LAN cards (in any combination).

  • Page 27: Operator Interfaces

    Operator Interfaces Installation of FRX6000 software into a node, generally done before the node ships to the customer, requires a directly connected keyboard and monitor. Once the node has been installed and configured, it can function with no operator interface. However, configuration, file copy (backup, restore, transfer, etc.), and monitoring operations require a keyboard and screen, which can be in any of several forms.

  • Page 28: Frame Relay Module

    Frame Relay Module The Frame Relay Module mounts into an MMAC-Plus chassis, and connects to an Ethernet module in the chassis via a cable from an Ethernet port on the FRM. The FRM draws power from the chassis, but does not interact with other modules in the chassis (except the Ethernet interface module).

    Serial and LAN Interfaces Figure 1-7 Frame Relay Module with I/O Boxes and Cabling As shown in the figure, each 60-pin serial connector on the FRM supports up to four I/O ports, all of the same interface type. A cable carries each connector’s signals to an I/O box assembly.
  • Page 30 Operator Interfaces Installation of software into an FRM, generally done before the node ships to the cus- tomer, requires a directly connected keyboard and monitor. Once the node has been installed and configured, it can function with no operator interface. However, config- uration, file copy (backup, restore, transfer, etc.), and monitoring operations require a keyboard and screen, which can be in any of several forms.

  • Page 31: Introduction To Menu Operations

    Introduction to Menu Operations The FRX/FRM user interface consists of a series of menus and sub-menus that are used to configure, control, and monitor a node. To protect the system from unautho- rized access, menu operations are accessible only after the operator enters a password. When running outside the menu operations, a display will be similar to the following figure, and will show the current status of all ports on the node.

  • Page 32: Moving Through The Menus

    After the operator presses (described on page 3-2), the Main Menu will appear: This is the starting point for all menu operations. The organization of the menus is shown in Appendix G. Moving Through the Menus To select a menu item, press the letter to the left of the item. To return to the next higher menu from a lower-level, press To move from operations under one Main Menu entry to operations under another entry, you must return to the Main Menu.

  • Page 373: Appendix A Subscriber Addressing

    Appendix A Subscriber Addressing Connections between subscribers are made over either switched virtual circuits (SVCs) or permanent virtual circuits (PVCs). An SVC is established by successful transmission and acceptance between subscribers of a Call Request, and broken by successful transmission and acceptance of a Clear Request. A PVC is established auto- matically on power-up of both subscribers (assuming both subscribers' nodes are oper- ational).

The method is proprietary, but is described generally here.
  • Page 376 If the database is changed and lines are added or deleted from the routing path config- uration, or if lines become operational or not operational, the next Call Request will trigger new fill up their LCNs they are excluded from getting new calls. If all operational lines have all LCNs in use, new calls will be cleared.

    Before establishing an end-to-end link, an async terminal must make a connection to the async PAD, as follows: 1. Once the FRX/FRM, async terminal, and any modems in the link are powered on, do this at the terminal: 2. If the port is configured (in the Port record) to not require login, go to step 3. If login is required, enter (when prompted) the login password defined in the Async PAD Login record (described on page 10-7).

Router is a device that receives data and routes it based on decisions made concerning the most desirable path.
  • Page 411 stands for IBM's “Systems Network Architecture.” Spanning Tree Algorithm is a method employed in bridging that avoids closed loops in the data path by deter- mining the bridge with the lowest “path cost,” which is the cost of transmitting a frame onto the LAN.
  • Page 412 is a CCITT recommendation that defines the service provided by an asynchronous PAD to connect a character-mode terminal to an X.25 network. X.25 is a CCITT recommendation that specifies the DTE/DCE interface for “packet mode” operation in public data networks. XPAD is an integral (to an FRX/FRM) transparent SNA PAD.
