    SmartSwitch 1800 Figure 1-1 Network Example Each FRM is a two-slot module that mounts into a SmartSwitch 9000. An FRM can interact with other FRM modules, but not with other modules in the SmartSwitch 9000, with the exception of a cable connection from each FRM to a LAN interface module in the SmartSwitch 9000, which provides LAN connectivity to the WAN interfaces on the FRM.

    An FRM mounts into a SmartSwitch 9000, and connects to an Ethernet or Token Ring (depending on the model of FRM) module in the chassis via a cable from a LAN adapter port on the FRM. The FRM draws power from the chassis, but does not interact with other SmartSwitch 9000 modules except the LAN interface module and other FRM modules.
  • Page 22 RS-232 RS-422 As shown in the figure, each 60-pin serial connector on an 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. The I/O box acts as a "splitter" that carries signals to four 25-pin connectors.

  • Page 67: Chapter 7 Configuring Frame Relay

    Introduction Frame relay ports in the FRM are used to carry frame relay traffic, as well as other protocols encapsulated in frame relay (per RFC 1490, via logical X.25 ports over frame relay). A frame relay port can act as physical DCE, connecting to end-user devices, or DTE, connecting to a network or frame relay PVC.

  • Page 68: Frame Relay Backup

    Frame Relay Backup Frame relay virtual-circuit backup in the FRM provides frame relay DLCIs with auto- matic backup protection in the event of LMI loss or port failure. (A DLCI is con- sidered down/inactive if level 1 is down. If LMI is used, the DLCI is also considered inactive if not reported as active in a Full Status Message from the DCE.)

    Cause Codes Clearing Causes The clearing cause recorded in a call packet provides a high-level indication of why the call was cleared and where the error occurred (e.g., error by the source user, or internal network error). For example, when the diagnostic code indicates that a pro- tocol error occurred, the clearing cause might indicate that the error was committed by the destination user (i.e., remote procedure error).

The service point in the FRM connects to the NetView host via an LLC2 session (over LAN or frame relay), which is established at node IPL. LLC2 must be installed in either the service point node or another FRM that is connected to the service point node via X.25 (physical link or over frame relay per Annex G or RFC 1490).

  • Page 366: C-1 Netview Access Options Menu

    Local NetView Access The FRM supports a local NetView access function that allows the node operator to send commands from the node to lines and PUs. This function is only between the node and lines/PUs—the commands and responses are not transmitted to NetView.

  • Page 367: Supported Commands

    NetView Management from NetView is generally as follows: RUNCMD is the VTAM PU name of the FRM (NetView sees the FRM as a PU), is the ID of the NetView operator issuing the command, and is the text of command sent to the FRM.

This term is synonymous with “alarm.” Fragment is an IP datagram that is a piece of a larger datagram, the larger one having been seg- mented to allow it to pass through a network that did not support the larger datagram.
