LAN –Two INDeX System - Single Site
The configuration outline below provides the VoIP connectivity for an extended Ethernet LAN operating at 10/100Mbs. This application does not provide any connectivity for
INDeX 1 | INDeX 2 |
192.168.42.1
LAN
192.168.42.201
192.168.42.2
192.168.42.3
Notes: 1. Both INDeX systems are connected to the LAN via the LAN interface an there are no routers between the two systems.
2.INDeX 1 System will allocate VoIP parameters. There are no other DHCP servers on the network
3.The IPNC VoIP Gateway function resides solely on the LAN1interface. The IPNC listens for VoIP Gateway connection on the LAN1 interface IP address only. This does not preclude the use of LAN2 interface for the VoIP transmission. An appropriate routing entry, on both IPNCs, would be required to allow the IPNC to route via LAN2 and access the LAN1 subnet of the partnering INDeX (a similar method is used in the next example).

| Description |
|
|
|
|
|
|
|
| Step 1 |
|
|
|
|
| Obtain the configuration file for INDeX 1 |
|
| Using the configured mask and IP address the IPNC is |
|
| and perform the following tasks: |
|
| able to derive the network address of the interface. It is |
|
| • Unique System Name |
|
| not necessary to add a routing entry in support of the |
|
| • Assign the appropriate IP address |
|
| configured LAN1 or LAN2 network address. |
|
|
|
| See The System Configuration Menu on page 32. |
| |
| to the LAN1 interface. |
|
|
| |
| Step 2 |
|
| Notice that the IP address for INDeX 2 IPNC falls outside |
|
| Obtain configuration file for INDeX 2 and |
|
|
| |
| perform the following tasks. |
|
| the IPNC default DHCP scope (200). |
|
| • Unique System Name |
|
| The DHCP server must be disabled on this unit so as not |
|
| • Assign the appropriate IP address |
|
| to conflict with the DHCP server configured in the |
|
| to the LAN interface |
|
| previous step of INDeX 1. |
|
| • Disable the DHCP Server |
|
| See The System Configuration Menu on page 32. |
|
|
|
|
|
|
|
| Step 3 |
|
|
|
|
| Test Connection |
|
| A common mistake with this configuration is to assign IP |
|
|
|
|
| addresses to INDeX 1 and INDeX 2 such that they reside |
|
|
|
|
| on different subnets. |
|
|
|
|
| The IPNC is configured correctly if both INDeX1 and |
|
|
|
|
| INDeX 2 respond to a PING for the PC attached to LAN. |
|
Note: The IPNC setup for 'Remote Terminal Users' is identical to that given for VoIP trunking in the example above, except that the numbers used will be for 'Reserved Number' (default 18) for the required number of terminals. Refer to the INDeX Programming Manual for details.
