# Configuring TCP/IP

Before you begin, ensure that the NPUM Voicemail Networking software blade is installed.

## Configure NP Net TCP/IP

This procedure describes how to configure the low-level NP Net TCP/IP parameters.

1. From the Main Menu, select (S) System Maintenance, (R) Reconfiguration, (R) Reconfigure System, (G) Offline Menu and then (N) NP Net TCP/IP Menu.

2. Select (H) Host Number to configure and enter the module number on which to configure NP Net TCP/IP. The module must contain an Ethernet card.

3. Select (I) Ethernet Card Configuration and enter the number (1-2) of an enabled Ethernet card in the module. You can only configure NP Net TCP/IP on one module of a multi-module NP-UM system.

4. Select (N) System Node Name and enter the name (1-15 characters) of the node.

5. Select (M) System Network message limitand set the maximumnumber of minutes(1-99) for a network message. The local node will reject messages that exceed this limit.

6. Select (R) Receive Circuits and enter the number (2-9) of receive circuits to be used by NP Net. The number of circuits determines the throughput.

7. Select (S) Send Circuits and enter the number (2-9) of send circuits to be used by NP Net. You can configure a node with more of one type of circuit than the other, if needed.

8. Select (T) System Local Node Number and enter the number (1 - 8191) of the local node used by NP Net for message routing.

   - Note: The default system local node number is 1. Assign a different number (2, 3, etc.) to reduce the chance of conflicts with other systems.

9. Exit to the NuPoint Voice Configuration Main Menu to save your changes.

10. When you configure NP Net TCP/IP for the first time, you must reboot before you activate the configuration.
