1 lan/intranet: configure ip networking
2 h.323: configures gateway, gatekeeper, dialing speeds, qos, and firewall settings for the viewstation
3 snmp: sets up remote management
4 global address: specifies server ip, preferences, dialing rules, private network, and gateway numbers
5 global management: sets up global management
lan/internet
the lan & intranet screen (system info ] admin setup ] lan/h.323 ] lan/intranet) shown in figure 2-34 contains information needed for h.323 videoconferencing.
host name: the host name is the dns name given to the viewstation by the lan manager or the viewstation administrator. it may be used in place of an ip address when dialing h.323 calls. for example, the host name of the viewstation may be “lobby” but the dns name for that viewstation is lobby.austin.polycom.com.
wins resolution: wins resolution determines the ip address associated with a network device.
1 checked: the viewstation sends requests to the wins server for wins name resolution.
2 not checked: the viewstation does not send any requests for name resolution to the wins server.
the viewstation sends a request for wins resolution to the wins server up to 15 times. after 15 tries, the viewstation stops sending wins resolution requests to the server.
dhcp: dynamic host configuration protocol is used to auto-assign ip addresses within a lan.
1 server: the viewstation dhcp server assigns up to 12 ip addresses from 1.1.1.3 to 1.1.1.14 when this option is checked.
if the dhcp server option is not present, run the viewstation softupdate to enable the dhcp server option setup. see "upgrading software" on page 165.
2 client: the dhcp server automatically assigns an ip, dns server address, a default gateway, subnet mask, and the wins server address.
when this option is selected, ip, dns, default gateway , subnet mask, and wins server address fields cannot be changed.
3 off selected: when off is selected, the lan manager or viewstation administrator must enter all values as static addresses. these values do not change unless manually changed.
?1 ip address: enter the static ip address assigned to the viewstation
?2 dns servers: the viewstation supports up to four dns servers for multiple lans
?3 default gateway: enter the server's default gateway address
?4 subnet mask: enter the subnet mask for the lan
?5 ins server: enter the wins server address for the lan
h.323 setup
the h.323 setup screen (system info ] admin setup ] lan/h.323 ] h.323) shown in figure 2-35 is used to configure the h.323 communication protocols for the viewstation.
the following five items configurable by the user are:
1 setup: defines the h.323 name and extension for the viewstation. see "setup" on page 67.
2 gateway: defines the gateway speed, prefix, and suffix used for the viewstation. see "gateway" on page 69.
3 gatekeeper: defines the gatekeeper operation parameters for the viewstation. see "gatekeeper" on page 70.
4 dialing speeds: defines the videoconferencing speeds for the viewstation. see "dialing speeds" on page 71.
5 qos: defines firewall and nat parameters for the viewstation. see "quality of service (qos) and firewalls" on page 72.
setup
the h.323 setup screen (system info ] admin setup ] lan/h.323 ] setup) is used to specify the h.323 or ip name.this information applies to the h.323 feature included with all models.
the h.323 extension (e.164) is a naming scheme based on the viewstation serial number. this number must be unique to the viewstation.
an auto h.323 dialing check box appears below the h.323 extension (e.164) field.
h.323 name when calling this system: enter a name in the text box. this name is displayed on the far site during a videoconference. use a name which is easy to remember such as the name of the conference room.
·h.323 extension (e.164): e.164 is a naming scheme used to identify the viewstation with the h.323 name.
auto h.323 dialing: the viewstation determines how a call is placed based on the number dialed and speed selected. for example:
for h.320 calls: if the number dialed is 555-1234 and the speed is 2x64, the viewstation provides an additional field to place dials a nonbonding h.320 call.
for h.323 calls: if the number is 255.255.255.90 and the speed is 2x128 then the viewstation dials a nonbonding h.323 call, but only provides one placeholder for h.323 calls.
if you dial by dns name or pbx extension, do not check this feature.
1 checked: the viewstation assumes the video call is for h.323 videoconferences and provides only one placeholder to make a video call.
2 not checked: the viewstation provides an option to place ip or isdn calls as shown in figures 2-37 and 2-38.
gateway
the gateway screen (system info ] admin setup ] lan/h.323 ] gateway) is used to configure the gateway profile in accordance with a specific gateway used on a lan. the prefix and suffix are preprogrammed on the gateway with a bandwidth used to make a call. for example:
72569
1 the number 7 is assigned to a specific radvision gateway.
2 the number 256 is the bandwidth speed at which the gateway places a video call.
3 the number 9 tells the gateway to place a call outside the lan.
the gateway places calls if the bandwidth number corresponds to the correct line speed. for example:
an invalid speed is 255. valid bandwidth speeds are listed on the gateway screen shown in figure 2-39. the gateway rejects and invalid speed and does not connect the call.
the gateway configuration has no effect if a gatekeeper or gateway is not used.
gatekeeper
the gatekeeper screen (system info ] admin setup ] lan/h.323 ] gatekeeper) shown in figure 2-40 is used to enable, disable, or configure an h.323 gatekeeper.
off: the gatekeeper is not used. the gatekeeper ip address text field is not accessible.
specify: the gatekeeper is used. enter the gatekeeper ip address in the grey text box. contact the lan manager to obtain the gatekeeper ip address.
auto: when set to auto the viewstation automatically searches for the presence of an available gatekeeper. if a gatekeeper is not used and auto has been selected, the viewstation remains in auto mode until changed.
a gatekeeper is not required to make ip-to-ip intranet calls.
if specify or auto is selected, one of three icons appears on the viewstation main calling screen when the viewstation is rebooted. these icons are:
1 red gk (gatekeeper) down arrow: cannot find gatekeeper
2 yellow gk box: found gatekeeper, but not allowed to register
3 green gk up arrow: found gatekeeper and registered
dialing speeds
the dialing speeds screen (system info ] admin setup ] lan/h.323 ] dialing speeds) shown in figure 2-41 is used to set the h.323 and h.320 dialing speeds for the viewstation.
1 nx56 and nx64 (left side of screen) represent the dialing speeds for h.320 calls.
2 ipx56 and ipx64 (right side of screen) represent the dialing speeds for h.323 calls.
the 2x options listed under ipx56 are used for gateway calls from the viewstation. non-2x options provide connection speeds from 56 kbps to 768 kbps.
quality of service (qos) and firewalls
the quality of service and firewalls screen (system info ] admin setup ] lan/h.323 ] qos) shown in figure 2-42 allows the lan manager to use fixed or nonfixed tcp and udp ports, select the ip precedence, network address translator (nat), and firewall options. the following options are configurable:
use fixed ports: specifies the fixed ports assigned to the viewstation when protected by a firewall.
ip precedence: specifies the priority given ip packages sent from the viewstation. for ip precedence to work, all routers on the network must be configured to allow ip precedence.
system is behind a nat: this option instructs the viewstation to use the ip address that appears in the nat outside (wan) address field as its external ip address. when using a virtual private network (vpn) for your network connection, make sure that system is behind a nat is not selected.
auto discover nat: this options automatically assigns the wan ip address to place calls outside the wan.
nat outside (wan) address: specify the external ip address used by the nat if viewstation is unable to discover the external ip address automatically.
for more information about configuring the viewstation for operation behind a nat (network address translation), see "network address translation" on page 189.
snmp
the snmp setup screen (system info ] admin setup ] lan ] snmp) provides for remote management from an snmp console.
the viewstation sends snmp reports on the following:
1 low battery power in the remote control.
2 the system is active (powered on) after a long period of inactivity.
3 authentication failure: an attempt has been made to log in as an administrator with the wrong password.
4 authentication success: the administrator has logged in successfully.

gateway number
the gateway number feature (system info ] admin setup ] lan/h.323 ] global address ] gateway number) is not available at this time. these features will be available in a future release of the global management system.
dialing rules 1
the dialing rules 1 screen as shown in figure 2-50 (system info ] admin setup ] lan/h.323 ] global address ] dialing rules 1), is used to set network dialing rules.
viewstation number(s) are automatically normalized for the address books of other viewstations. global dialing takes into account the numbers, area codes (or city codes), country codes, and international dialing access codes for viewstations which are placing and receiving calls.
if the viewstation is in an organization’s private network as well as a public network, additional information may be required to assist the gab on how to call other systems on or off the private network. if the viewstation uses a public network exclusively, additional information is not required.
the gab uses the following dialing rules when calling a public network or a private network.
the private network dialing rules are used to define a set of rules unique to the location of the viewstation.
number of digits in extension: set the number of digits in the dialing extension. this usually applies to systems that are connected to a pbx.
international dialing prefix: enter the prefix required to place international calls. this prefix is automatically inserted before any international calls are made from the gab. this overrides the international dialing prefix that is normally set in the viewstation country setup screen (system info ] admin setup ] general setup ] country).
public network access (use public network):
1 checked: the viewstation can dial calls outside of the private network.
2 not checked: the viewstation cannot place calls outside of the private network.
public network dialing prefix: enter a dialing prefix as required by the pbx to dial out to the public network. this prefix is automatically inserted before dialing numbers to the public network from the gab.
public network (same area code) prefix: enter a prefix if one is required to call within the same area code.
private network access (use private network):
1 checked: this option enables calls from a private network.
2 not checked: this option disables calls from a private network.
private network dialing prefix: enter the dialing prefix required to dial within a private network. this prefix is normally used to access an organization from inside the private network.
dialing rules 2
the dialing rules 2 screen (system info ] admin setup ] lan/h.323 ] global address ] dialing rules 2) is used to set network dialing prefixes for different area codes.
if the private network requires a dial prefix to access certain area codes (or city codes), set these prefixes on this screen. this prefix is dialed before the area code. for example, some sites require a 9 before dialing a 1-800-xxx-xxxx number.
enable the always dial area code option if you must dial the area code to sites that have the same local area code as the viewstation. this is sometimes necessary for 10-digit dialing.
