Access control for Global Voice systems is via a single Global Request / Grant / Deny
scheme. In order for a local command station to have control of its own voice
functions and speaker zones, it needs to request control from the command station
that currently has it. Only one command station can be active at a time.
The single access control method only allows a single page to occur at any given
time. The page will be a global page, which may either be limited in scope to a single
node (simulating a local page) or performed across multiple nodes.
The following options are configurable in Zeus 7 .0 or higher to change access:
1. Instant—Access is automatically granted on request (Global Request).
2. No Time Out—Press Global request. Must wait until access is granted by station
having control. If user with control does not grant or deny access before time out,
then the requesting command station is given access.
3. Specific Time Out—(The time period is selectable in Zeus.) Gain control when
time out occurs or person grants control.
In a Global Voice system, the requesting Command Station determines the Time Out
period.
In a Stand Alone Voice system, the Time Out is determined by the active Command
Station.
The active command station is indicated by a solid green Global Request LED. When
the Global Request switch is selected on a non-active command station, it will flash
green until the completion (or denial) of the request. In addition, the Global Grant and
Global Deny switches will be lit on the active command station while a request is in
progress (with the access control sounder active).
The Global Request / Grant / Deny scheme follows the same rules, including the
same rules for LED control, as the existing single-node Voice system.
Since access control is required and only a single command station (local or global)
may have access control, concurrent operation (as allowed on existing single-node
Voice systems via multiple command stations without access control) is not provided.
