| Network Parameter Definitions (cont’d) |
Field Name | Values | Description |
Call Mode |
| |
|
| |
Direct Mode |
| Sets the call mode to direct. In this mode, terminals send ARQ messages |
|
| to the Gatekeeper, but pass the call signaling and media control |
|
| signaling directly between them. |
|
|
|
Routed |
| Sets the call mode to routed. In this mode, terminals pass admission |
Mode |
| requests and call signaling through the Gatekeeper. Media control |
|
| information is sent directly between the terminals. |
|
| Note: Though direct calls consume fewer Gatekeeper resources, call |
|
| control is better for indirect (or routed) calls. |
|
|
|
Configuration |
| |
Parameters |
| |
Max |
| The maximum number of concurrent calls allowed in the zone. This |
Number of |
| number is fixed to 5, 10, or 15 call for |
Calls |
| MVP810 models respectively. |
|
|
|
Max Total |
| The amount of bandwidth in Kbps that call traffic can consume at any |
BW (KBps) |
| given time. |
|
|
|
Registration |
| Registration Timeout. Sets the number of hours of inactivity after |
TO (hrs) |
| which the dynamic registration of a terminal expires. Only the dynamic |
|
| (online) properties will be unregistered. If the endpoint is also static |
|
| (predefined), the static properties remain valid. |
|
|
|
IRQ Interval |
| The interval, in seconds, between IRQ messages sent by the Gatekeeper. IRQ |
(sec) |
| messages are sent to all online endpoints registered as dynamic in order to |
|
| verify that the endpoints are online. The number you set determines the delay |
|
| between two IRQ messages to the same endpoint. Choosing the desired delay |
|
| should take into account the following factors: |
|
| • IRQ messages add to the traffic already present over the network, and the |
|
| shorter the delay, the more IRQ messages are sent. However, the longer the |
|
| delay, the longer it takes for the Gatekeeper to detect dynamic registrations |
|
| that have ceased to be online. |
|
| • The delay parameter relates to the interval between two IRQ messages per |
|
| one endpoint, so the actual number of the IRQ messages the Gatekeeper |
|
| creates during this interval should be multiplied by the number of |
|
| endpoints registered dynamically. |
|
| • To disable the IRQ polling, set this value to zero. |
|
| • The effective IRQ interval cannot fall below three times the RAS timeout. |
|
| • IRQ messages will not be sent at a rate exceeding 20 per second. |
