5129 Protocol Overview

When you configure a 5129 connection using the System Manager, you establish a connection from the SDA System Manager to an NMS or LSMS. Therefore, the port number and  IP address in NODE-A or NODE-B of the 5129 Protocol Interface window refers to the port number of the far-end NMS, not a physical port number on the SDA System Manager. The port number referred to in the System Manager is a TCP socket, which is a logical interface rather than a physical one. Therefore, there is nothing to install and no cables to attach when configuring the 5129 connection.

Once a 5129 connection is established, the NMS functions as the server while the SDA System Manager functions as the client. The System Manager initiates TCP/IP connections to the NMS system. The System Manager does not accept TCP/IP connection requests from the NMS. The NMS server application software should “listen” for a port number assignment from the System Manager. See the following figure.

The 5129 Protocol Interface Window

The 5129 Protocol Interface window is used to set up and view the status of the 5129 protocol interface between the SDA System Manager and the NMS. The following figure shows the 5129 Protocol Interface window.

5129 Protocol Interface Window

The 5129 Protocol Interface window displays the following:

  • Modify 5129 server application parameters

See Configuring the 5129 Protocol Interface for procedures on configuring the Interface.

Menu Bar

The menu bar in the 5129 Protocol Interface window contains the common application menus: File, Edit, Dock, View, and Help. The Edit menu contains the Copy and Paste options. For more information about common application menus, see About the System Manager.

From the 5129 Protocol Interface window, the following table provides details on options available in the Configure menu.

You can perform the following tasks by clicking on the toolbar icons:

  • Add Connections - add connections by adding ports to an existing IP address or by adding a new IP address.
  • Modify Connection - modify the IP Address, Connection ID, Destination Node Name, Destination Port Number, Connection Priority, Shutdown/Restart, Available  DRCs, Assigned DRCs for an individual connection.
  • Delete - delete a port associated with an IP address or delete an IP address and all of its connections.
  • Refresh - refresh the connection status information in the window.

NODE-A

Select NODE-A in the application tree. See the following figure.

5129 Protocol Interface, Destination Details in NODE-A and Assigned DRC

The NODE-A  displays the following:

  • Destination details in NODE-A panel
  • Assigned DRC panel

You can perform the following tasks in NODE-A:

  • Add a 5129 interface connection
  • Modify a 5129 interface connection
  • Delete a 5129 interface connection
  • Shut down all 5129 interface connections
  • Shut down a selected 5129 interface connection
  • Restart a selected 5129 interface connection
  • Restart all 5129 interface connections

For more information, see section Configuring the 5129 Protocol Interface for detailed steps on configuring the 5129 Protocol Interface.

Destination Details in the NODE-A Panel

The Destination Details in the  NODE-A panel displays the following:

  •  IP Address - the IP address of the message router of the NMS. An NMS supports multiple message routers on separate platforms with multiple IP addresses. Only 10 IP addresses can be configured in this window.
     
  • Port - port number of the message router of the NMS. Only 10 ports can be configured for each IP address. Each port number assigned to one IP address must be unique.
     
  • Priority - priority of the ports. The possible values are High, Low, and Autonomous. Autonomous messages are sent by applications via 5129 interface due to some event or periodic messages that are not received in response to any command.
     
  • ID - an internal sequence number. You cannot change this number. ID is used in the Modifying connection dialog box to choose which port of an IP address to modify.
     
  • Source Node -  ASCII value used as the node name by the server application. The source node is automatically generated by the system when a new connection is added. The Source Node includes the switch site ID, NMS connection port number, IP identity (00-99), and SM side identifier. For example, 080500001A, where 08 is site ID, 05000 is the NMS port number, 01 is the IP identity, and A is the SM side identity. If you click on Node-B, then the source node name changes to B accordingly.
     
  • Destination Node - NMS node name. It is unique for all the connections of an IP address.
     
  • Status - status of the  TCP/IP socket connection with the NMS. The possible values are ACT, CNF-CONNT, CNF- REACH, AOS, and MOS. See the following table.

 

In the standby mode of the System Manager, if the ping to the remote IP is not alive, the Status column displays AOS with a red diamond icon. If there is minimum ping observed in the console, the Status column displays CNF-REACH with a yellow diamond icon.

Status of Connection

Connection Status

Description

ACT (Green)

A connection has been established with the NMS.

CNF-CONNT (Yellow)

A connection has been established, awaiting for protocol completion and configuration is in progress.

CNF-REACH (Yellow)

NMS is reachable by ping message and configuration is in progress.

AOS (Red)

Automatic out of service. NMS not reachable.

MOS (Red)

Manually out of service. Connection taken out of service manually.

NODE-B

The fields displayed in this node are the same as those in NODE-A.

Configuration

The Configuration node displays details about the parameters and servers. See the following figure.

5129 Protocol Interface Configuration

The Configuration node displays the following:

  • Parameters
  • Servers

Parameters

Use the Parameters node to change or update the parameter values. See the following figure.

5129 Protocol Interface Parameters

You can perform the following task in the Parameters node: 

  • Modify 5129 server application parameters

The Parameters node displays the Parameter Details panel:

  • 5129 Version Number - a display field only showing the 5129 version number to be used in the header of all messages. You cannot modify the 5129 Version number.

  • Connection Retry Interval (sec) - time between attempts to connect to the NMS. Attempts to connect to all configured ports are continually retried except for those that are in the Connected or Shutdown state. The valid range is 1-3600 seconds.

  • Good Day Keep Alive Time Interval (sec) - after establishment of a connected session, this interval is the amount of time the System Manager allows to pass without receiving data from the NMS. If this time interval is exceeded, the System Manager issues a Good Day message with the destination node name field in the message set at zero length to try to force the NMS to respond to the message. The valid range is 1-3600 seconds.

  • Good Day Keep Alive Threshold - for an established connection, this threshold defines the allowed number of intervals with no data received from the NMS before closing the session. When this threshold is reached, the System Manager sends a Good Night message to the NMS, sets the connection status to  AOS, and starts trying to re-establish the connection. The valid range is 1-23.

  • CLLI - common language location identifier. An 11-digit alphanumeric identification code for the Ribbon Signaling System. The CLLI consists of:
    • CCCC - city, town, or locality code
    • SS - state or province code
    • BB - building code
    • UUU - traffic unit identifier

  • Database Specific - the 5129 database can be setup as node specific or non-node specific. Click the Node Specific or Non-Node Specific option button to configure the 5129 database.

    When the 5129 database is setup as node specific, the database is different for System Manager A and B.

Servers

The Servers node displays details of servers that are registered with the 5129 server to send and receive UPL messages. See the following figure.

The only supported DRC code is FLX for SDA.
