To verify your Ethernet port configuration
Decide where, in your network, you want to install the server. It is best to install
OmniTouch ACS on a dedicated Ethernet segment. OmniTouch ACS is usually deployed
with other web servers, behind a firewall, often in an enterprise’s DMZ.

1
Verify your LAN’s Ethernet port configuration.
When you connect OmniTouch ACS to your LAN, the OmniTouch ACS’s Ethernet
port will attempt to auto-negotiate with your LAN’s Ethernet port to the highest bit
rate that they have in common. OmniTouch ACS software is capable of 10/100/1000
Mbit rates. Bandwidth considerations for the primary Ethernet interface are as follows:
•
For PSTN-only servers or PSTN server stacks, a 100Mb interface is adequate.
•
For VoIP-only servers:
A 100 Mb port will accommodate up to 300 simultaneous ports of voice conferencing.
For more than 300 ports per server, a 1Gb interface is required.
The Alcatel-Lucent software is certified for up to 400 ports of voice conferencing per
server, but when taking advantage of stacked systems, the actual number of VoIP
streams may be greater. For this reason, it is good to factor into the plan for headroom
when determining the amount of network bandwidth to provide. See additional
information in Appendix B .

2
Determine your firewall configuration.
OmniTouch ACS does not provide firewall/port blocking. When configuring your
firewall, see Chapter 4, “Opening Ports in Your Firewall” for open ports required by the
server.

3
Verify that your NAT configuration is compatible with SIP.
If you are using the Network Address Translation (NAT) protocol and you expect
Session Initiation Protocol (SIP) devices or applications that are exterior to your
network to be communicating with OmniTouch ACS, there may be an issue when
using SIP, which OmniTouch ACS uses for all VoIP and IM signaling. Newer NAT
devices often list “SIP enabled” as a feature; it can be challenging to configure older
NAT devices to accommodate SIP.
