ApexPro Receiver Configuration

Revision C
Equipment Overview: Theory of Operation
Every installation has an ApexPro master tower. The ApexPro tower having the
highest IP address determined through RWHAT packet monitoring, is the master
tower. The ApexPro tower with the highest IP address is always the master tower,
even on a mixed network having both ApexPro and CDT-LAN towers.
The master tower has two specific duties:
It receives all telemetry patient admit requests and directs them to appropriate
towers. This is referred to at the admit master function.
It maintains a list of all in-use transmitter numbers, so that patient admissions
can be prevented from using an already-allocated transmitter. This is referred to
as the TTX master function.
CDT-LAN is a telemetry system which precedes ApexPro. ApexPro is designed to
allow for mixed networks including CDT-LAN running version 6D software.
Unlike CDT-LAN, ApexPro systems do not assign specific receivers to specific
units — receivers in a tower can be generically configured to accept admits from
any unit. This provides certain amount of receiver assignment flexibility and
control, but it is important to understand the underlying mechanism in order to take
full advantage of it.
An ApexPro tower can contain a pool of up to 16 receivers. Any number of these
receivers from this pool can be "reserved" to only accept admits from specific units.
Understand that this does not assign specific receiver slots. It assigns a quantity of
them. When an admit occurs, any available receiver from the pool is used:
IF the tower is configured to accept the admit from the unit.
IF the unit has not used up it's allotted number of reserved receivers.
If the number of receivers that are reserved is less than the total number of receivers
in the tower, there are unassigned receivers available. For example: a tower has a
pool of 16 receivers, and 8 of them are reserved for one or more units, leaving 8
unassigned receivers remaining.
