Polycom Audio and Video manual Setting Up Your IP Network Connection, Calling Within an Intranet

	Chapter 3 - Configuring Network Use
Setting	Description
LAN Speed	Specify the LAN speed to use. Note that the speed you choose
	must be supported by the switch.
	Choose Auto to have the switch negotiate the speed
	automatically. If you choose 10 Mbps or 100 Mbps, you must also
	select a duplex mode.
	Note: The LAN speed setting for the V500 and the switch must
	match. Polycom strongly recommends that you do not select Auto
	for either only the V500 or only the router; the settings for both
	must be the same. Typically, selecting Auto for both is sufficient.
Duplex Mode	Specify the Duplex mode to use. Note that the Duplex mode you
	choose must be supported by the switch.
	Choose Auto to have the network switch negotiate the Duplex
	mode automatically.

Setting Up Your IP Network Connection

The following is a list of the common ways you can connect your V500 to an IP network so that you can make video calls. Pick out the IP network connection type that most closely resembles how you plan to make your calls, then read the section that corresponds to that connection type. If you need help determining how your V500 connects to the network, contact your network administrator, network service provider, or Internet Service Provider (ISP).

❑If you’re limiting your calls to other systems within your company’s intranet, refer to Calling Within an Intranet on page 3-5.

❑If your V500 system plugs directly into a cable or DSL modem, without a router in between, refer to Calling Through a Cable or DSL Modem on page 3-6.

❑If your V500 system connects to the network through a router, with or without a firewall or Network Address Translator (NAT), refer to Calling Through a Network Router on page 3-6.

❑If your V500 system is set up in a Demilitarized Zone (DMZ), refer to Calling Through a Router, Using a DMZ on page 3-12.

Calling Within an Intranet

An intranet is a private network within a company or organization. Calls within an intranet don’t access the Internet, so security isn’t an issue. Even if your company has a firewall, intranet calls remain within the firewall, so you can easily communicate with anyone within your office network.
