Use the SV+ Connection Manager to create and maintain end-to-end Frame Relay and ATM connections. Frame relay connections include dial-up and dial backup connections when the network is enhanced with the Intelligent Network Server (INS) Dial-Up Frame Relay application. Parameters that you define at the Connection Manager Window are validated and sent to either the INS server or Connection Manager server.
Note: INS Dial-Up and Dial-Backup connections are not physically added to a frame relay network until an INS user dials into the network. Even though they are configured by the StrataView Plus Connection Manager, these connections are considered dormant until they are needed. The INS DAS Server Shelf Installation Manual and the INS Dial-Up Frame Relay Operations Guide provide detailed information about instating and configuring the INS Dial-Up Frame Relay application, and includes instructions for using the Connection Manager.
You can open up to four Connection Manager windows at a SV+ desktop.
The Connection Manager Window presents updated status information as dependent on the Connection Mode selected at the Main Window. Connection Modes are either Normal Mode or Dial-Up Mode. Normal Mode presents standard Frame Relay and ATM Connections (PVCs), and Dial-up Mode presents INS Dial-up and Dial-Backup connections (PVCs).
Use this window to configure end-to-end frame relay and ATM connections.
| Connection List Filters | This portion of the window is used to specify the filters that should be used when building the Connection list. Once all the desired fields have been filled, press the 'Apply' button to update the connection list. |
| Connection Mode | This button toggles to either Network mode or INS ANI mode.
Normal mode displays standard Frame Relay and ATM Connections (PVCs). INS ANI mode displays the INS Dial-Up and Dial-Backup Identifications (ANIs). |
| Connection Type | A radio box allowing the user to specify the type of connection to be configured. Connection Type may be FR - FR, ATM - ATM, ATM - FR, or CE - CE. |
| Connection Status | A radio box allowing the user to specify 1 or more types of connection status that should be used to filter the list of connections. Connection Status may be OK, Failed, Incomplete, and Down. |
| Local Information | Node name and port number of the local end-point. Any or all these fields may be specified. The button with the "..." label next to the shelf text entry field opens a scroll list of node names and a corresponding shelf name if the node name entered corresponds to a BPX. |
| Remote Node Name | A text edit window for the user to specify that only connections to this remote node from the local node will be displayed. If no remote node is designated, connections from the local node to all other nodes are to be displayed. |
| Connection List | A scrolling text window displaying all the connections which match the filter criteria. The user may select one or more entries from this list for modification or delete. Each entry in the list has the following format: |
| Local end-point | <nodename>.<interfaceshelfname>.<slot>.<port>.<DLCI> or <nodename>.<interfaceshelfname>.<slot>.<port>.<vpi>.<vci>
If the end-point is a frame relay end-point the first format is used, if it is an ATM end-point the second format is used. If shelf is not applicable the shelf field will be omitted. ci> For an ATM end-point the second format is used. If shelf is not applicable the shelf field will be omitted. |
| Remote end-point | <remotenode>.<interfaceshelfname>.<slot>.<port>.<DLCI> or <remotenode>.<interfaceshelfname>.<slot>.<port>.<vpi>.<vci>
If the end-point is a frame relay end-point the first format is used, if it is an ATM end-point the second format is used. If shelf is not applicable the shelf field will be omitted. |
| Connection type | Connection Type may be FR - FR, ATM - ATM, ATM - FR, or CE - CE. |
| Connection status | Any incomplete connection segments in feeder shelves and BNI-BNI connection segment in BPXs display the unknown termination points as "Unknown" and an "Incomplete" status. The remote end may report BPX node, slot, port, vpi, and vci. |
| Apply button | This button updates the entries in connection list according to the criteria set in the filter field. |
| Refresh button | Indicates that the connection database has changed by changing its background color to red. This button updates the connection list with the new information |
| Associate Backup button | The Associate Backup dialog box has two basic functions, "Add Association", and "Delete Association".
The "Associated to PVC?" column indicates whether or not the Dial-Backup PVC is already associated to a Normal PVC If the Selected Normal PVC is already associated with a Dial-Backup PVC, then the Display fields at the top of the window are updated to indicate which ANI and which Dial-Backup PVC is already associated to this Normal PVC. If the Normal PVC is already associated, select "Delete" to remove the association. The user can then select a Dial-Backup PVC and "Add" to add a new association. The Add association is performed by selecting the Add Association... button. The selected Normal PVC is then associated with the selected Dial-Backup PVC. Only Dial-Backup PVC's that have NO association to a PVC can be selected for association. The Dial Backup ANI will never have more than five Dial-Backup PVC's. |
The ANI field is a 20 character numeric field. It is selected from a listbox that is popped up when the "..." button is depressed. When an ANI is selected, all of the connections defined on the INS server for the selected ANI are displayed.
The Main Window connection list display is changed in "Dial-Up" mode, with a connection Status of Active or Inactive in the connection(s) listbox field. Active INS connections cannot be modified. Only connections that are Inactive can be further modified via the main window Modify button or deleted with the Delete button.
To add a new Dial-Up connection to a n ANI, select the New button to begin addition of a new connection.
Use this window to set parameters for a new dialup connection.

In this section, we will focus on how a user adds a connection. Specific screens that follow will show the following types of connections:
Connection type--This section allows the user to specify the connection type further. For example for ATM-ATM, and ATM-FR connections the service type specification will be displayed here.
Originating/Terminating end-point definition--This section provides for the specification of the originating/terminating end-point. A user can choose an end-point type of ATM or Frame Relay. Different fields will be displayed for defining the end-point depending on the end-point type and the end-point card type. The end-point card type is automatically determined by the GUI.
An end-point is defined by its end-point type and its node, [shelf], slot, [line], port, and [channel] information. Examples of specific terminating end-point definitions are as follows:
The prompt for end-point definition has changed from the prompt used in Release 8.1. Instead of prompting for Node name, Interface Shelf, Slot, Line, and Port, you will be prompted for Node Name where Node Name will be in the form <Node Name.Shelf Name> and Port number will be in the form <slot#.logical port#>. A logical port number is defined to be unique across a given slot.
As an example; in order to represent node bpx01, shelf axis01, slot 5, line 1, physical port 1, logical port 10, dlci 100, for Release 8.1 you would enter:
bpx01 axis01 5 1 1 100
but in 8.2 you would enter:
bpx01.axis01 5.10 100.
Based on the end-point type appropriate Originating/Terminating end-point parameters are displayed in the region just below this one.
An ATM-ATM connection is one in which both originating and terminating end-point types are ATM.
Five different service types (CBR.1, VBR.1, VBR.2, VBR.3, ABR.FS) are supported for ATM connections. Based on the service type selected, the end-point and connection parameters are changed. Parameters that are common across the different screens are only described on the first screen that they are shown in.
Both ASI and AUSM end-points have the same parameters, the range and default values are different for the 2 end-point types. For each service type the range and default values for all relevant parameters are shown.
The Connection Manager GUI supports both VPC and VCC connections. For VPC connections the VCI value is specified as a '*' e.g. 5.* would be a VPC using VPI of 5.
Figure 7-6 shows the parameters required to add a CBR.1 ATM connection. In this case, from the users perspective both ASI and AUSM end-points have the same parameters. The ranges and default values that are valid for the two end-point types are listed in Figure 7-6. Additional end-point and connection parameters required by the network elements (BPX, AXIS) and not shown on the screen will be set automatically by Connection Manager Daemon.
ATM-ATM CBR.1 connection configuration parameters are shown below:

An ATM-FR connection is a connection that has an ATM end-point and a Frame Relay end-point. Only VCC connections are supported for ATM-FR connections. Valid service types for this type of connection are VBR and ABR.FS. Parameters for this connection are shown as per end-points.
Figure 7.5 shows the parameters required to add a FRSM to AUSM ABR.FS connection. FRSM end-points support both service interworking and network interworking options. In the case of FRP end-points only network interworking is possible.
The option menu for the end-point Type in both the originating and terminating end-point sections allow values of Frame Relay and ATM. The only restriction is that if ATM is specified in one end-point then Frame Relay must be specified in the other.
In Figure 7.6 an originating FRSM end-point and a terminating AUSM end-point are shown for a ABR.FS connection. The AUSM ABR.FS parameters are the same as those discussed earlier. The FRSM end-point supports the following additional parameters:
A CE connection is one in which both originating and terminating end-point types are CESM. Figure 7-12 shows the parameters required to add a CE connection.
