Distance Settings
Distance settings give you control over endpoint dialing options between zones. Distance
settings are arbitrary numbers that are chosen by you to designate a "logical distance" that
defines the access rights between zones for different endpoints in relation to an origin point
such as a particular gateway. There are four parameters for distance settings, which are
interconnected but are accessed from different configuration screens:
"
Neighbor Distance — Access this parameter from the Neighbor Gatekeepers screen.
"
Max. Distance — Access this parameter from the Zone Definition screen.
"
Default Distance — Access this parameter from the Network Control screen.
"
Multicast Distance — Access this parameter from the Network Control screen.
The following are descriptions of the Distance settings parameters:
Neighbor Distance — Determines the logical distance between zones. When you define
neighbor gatekeepers, you can define a logical distance between them. When you set a value
for this parameter, you also have to set the
Max. Distance and Default Distance parameters
for endpoints in this zone to be able to dial to endpoints in the neighbor gatekeeper zone.
Max. Distance — Determines how far outside the zone this endpoint can make a call. For
example, if an endpoint Max. Distance is set to 50 and it makes a call request to a zone that
you have defined as a neighbor gatekeeper with a Neighbor Distance of 100, the call is
rejected.
Default Distance — This is the equivalent of the Max. Distance parameter for online
endpoints that do not have predefined properties.
Multicast Distance — This is a logical distance determining how far outside the zone the
gatekeeper can route a call using multicast.

To set distance settings for a zone
1. From the Application Parameters screen, click Neighbor Gatekeepers . The
Neighbor Gatekeepers Table is displayed.
2. Click Add to define a new neighbor gatekeeper, or click Edit to edit one already
defined. The Neighbor GK Parameters screen is displayed. See Adding a New
Neighbor Gatekeeper .
3. In the Neighbor Distance field enter a number between 0 and 255. Click Ok to
confirm.
4. From the Application Parameters screen, click Zone Definition . The Zone
Definition Table is displayed.
