Spok Messenger Gateways: TNPP

TNPP Encoding Types

This screen allows the specification of the different encoding types accepted and sent by the system. The TNPP specification defines a number of preset encoding types. The encoding value zero (0) is interpreted as local ID paging. The TNPP Encoder Types dialog can be displayed by choosing the Interfaces > TNPP > Encoding Types menu option.

Name

The name used to uniquely identify an encoding type.

Value

The value assigned to uniquely identify an encoding type.

TNPP Local Addresses

The TNPP Local Node Configuration screen is used to identify various addresses for the local node. The TNPP Local Addresses dialog can be displayed by choosing the Interfaces > TNPP > Local Addresses menu option.

Local Address

Refers to the name that appears under in the list of currently defined TNPP Local Addresses.

Continue routing messages addressed to this node address.

Select this option to continue routing messages addressed with the above local address. Deselecting this option stops the routing of messages with this local address. Messages can still be received locally. This may be useful in creating a broadcast address or monitoring messages being routed through this system.

Default address

Identifies this address as the default address for this node. All outgoing packets are labeled with the default address. Note: only one address may be the default local address.

 

TNPP Remote Node Configuration

The TNPP Remote Node Configuration screen allows you to identify other nodes on your TNPP network. This screen allows you to specify where a node is located, how the node can be reached through the network, the method(s) used to send messages at that node, where to send received messages, and a variety of other details. The TNPP Remote Nodes dialog can be displayed by going to the Interfaces > TNPP > Remote Nodes menu option.

Name

The name used to uniquely identify a node/gateway on a TNPP network.

Node Address

The TNPP address of the remote node on the TNPP network.

Routes

Lists the routes taken to reach this node. When attempting to reach a node, the route chosen is in the order listed. Packets, when routed, are never sent back on the route from which it came.

Encoders

Identifies the encoding methods that this remote node supports. The remote node most likely delivers the message differently for each of the encoding types.

Route only supported encoding types

Used to provide a “deny all, except where explicitly enabled” TNPP firewall policy for this node. For example, when receiving a “Pocsag 512” message from one node to be routed to another node, it is first check to see if the other node is configured for the requested encoding dropped packets using “End to end error control,” the node originating the message is notified. For a “finer-grain” firewall, see encoding methods below.

End to end error control

Enables end to end error control. Used to check for transmission errors between nodes.

Broadcast

Select this option to broadcast TNPP messages on all routes. Packets, when routed, are never sent back on the route it came from. This option is not available with “End to end error control.”

Save

Saves changes.

Close

Closes this screen.

 

Route

This allows the definition of the route taken to reach the given remote node.

Port

Used to specify the port for what is used to route information to this remote node.

Inertia

Used to specify the maximum number of nodes that a TNPP packet from this server may be routed through before being aborted.

 

Encoding Methods

This screen allows you to identify the encoding methods that a remote node uses.

Encoding Method

Used to specify the encoding method that is used for this remote node.

Name

Identifies the encoder for each particular node.

Enabled

Used to temporarily enable or disable the encoder.

Max message length

Used to specify the maximum size of messages sent to this remote node according to the selected encoding method.

Threshold

Used to specify the maximum size of the queue threshold for outgoing messages.

Split long messages

Used to specify whether long messages are split into multiple messages when sending to this remote node, according to the encoding method.

Allow messages

Used to determine whether messages of this encoder type can be sent to this node.

Accept messages

Used to determine whether messages of this encoder type can be accepted from this node.

Enable routing to this node

Used to firewall TNPP packets that are routed by the system to this node. For example, when receiving a "Pocsag 512" message from one node to be routed to another node, it is first checked to see if routing is enabled to the other node. If routing is disabled, the packet is dropped. For dropped packets using "End to end error control," the node originating the message is notified.

Enable routing from this node

Used to firewall TNPP packets that is routed by the system from this node.

 

TNPP Diagnostics

This screen allows you to view diagnostics for TNPP. This screen is quickly identifying system faults.

By changing which ports are selected, you can select which TNPP Ports information you receive in the trace window. With no port selected, the trace window shows all port information.

The TNPP Diagnostics dialog can be displayed by choosing the Interfaces > TNPP > Diagnostics menu option.

Port

Textual description of the TNPP port.

Link

Displays the status of the TNPP link A tick indicates the link is known to be active. A cross indicates the link is known to be faulty.

Rx packets

The total number of packets received from other TNPP nodes.

Tx packets

The total number of packets transmitted from this TNPP node.

Routed

The total number of packets that have been requested to be routed from this node.

Rx bad

The total number of packets that have been received at this node corrupted.

Rx good

The total number of packets that have been received at this node without error.

Rx duplicate

The total number of duplicate packets received at this node

Rx reset

The total number of reset packets received at this node.

Rx expired

The total number of packets that are received at this node that have “expired” due to inertia value becoming cleared.

Firewall

The total number of packets received that have been dropped due to the configured TNPP routing rules.

Tx bad

The total number of packets that have been interpreted as being transmitted from this node as being corrupted.

Tx good

The total number of packets that have been interpreted as being transmitted from this node without error.

Tx reset

The total number of reset packets sent by this node.

No response

The total number of packets that have been sent and no response has been received.

Tx queue

The total number of packets in the queue for this node to be transmitted.

Pause

Temporarily pauses the display of TNPP diagnostic information being displayed in the trace window and if enabled, the capture file.

Capture

Sends a copy of the trace window to a text file.
