Dual Ethernet Port for SS7 Series 3 Card

Configuring Ethernet Ports

This section describes how to configure both Ethernet ports.

If you configure Port A to be on one subnet and Port B to on a different subnet, messages will not come from the desired physical ports.

Follow the steps below to configure the Ethernet ports:

1. From the IP Address Configure message (0x00E7), include the Module, IP Address, and Subnet Mask TLV (0x01).

2. Include the following module values and corresponding IP Addresses and Subnet masks:
0xFF - Port A
0x01 - Port B

3. Include a Reset TLV at the end of this message to force the SS7 Series 3 card to reset. This step allows the changes to get applied to the card.

Configuring the second Ethernet port is optional but if you enter an IP Address for Ethernet port B you must enter an associated Subnet Mask.

Important! Although a gateway IP Address may be configured for both Port A and Port B, you only supply one gateway address per physical interface.

The protocol used in most local area PC networks. Typically, most Ethernet networks support data transmission speeds up to 10 Mbps, but 100 Mbps is also possible.
The point in the Excel platform where a DS0 connects to a network. Also known as a "socket."
Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.
A 32-bit address, used in IP routing, which includes a Network address identifier assigned by a central authority and a Host ID (an end station identifier assigned by a LAN administrator).
The bits of an Internet Protocol (IP) address used for a subnetwork.
Tag-Length-Value block. A standardized block that allows data to inserted in a standard way into API messages.
