Capacity Plus (or Linked Capacity Plus) is a good functional trunked radio system, but it has a few unfriendly features that Capacity Max can resolve for users.
Like Capacity Max, Capacity Plus lets you have more user groups - talkgroups (or to put it simply, channels) than frequency pairs, thus saving upon license and hardware costs, but it’s biggest shortcoming is when you want to direct dial or make one to one calls.
With Capacity Plus the call either goes direct to air – i.e. speech from the receiving radio, or it fails, there’s no warning about the call, and if the user is in an existing group call it fails. With Capacity Max, you can make the receiving radio ring like a cell phone, and you can decide if you want the call, as it displays the caller ID or radio name. Operationally this is a much-liked user friendly feature.
Amongst other features, you also get call queuing, caller priority, full end to end encryption of the calls, and the ability to "kill” lost or abused radios remotely, with other management facilities such as being able to disable a radios operation on a talkgroup without having to reprogram the radio. Emergency Calls will also terminate calls in progress if the system is fully loaded, ensuring that emergency calls get through.
On larger systems, Capacity Plus restricts you to 8 repeaters, Capacity Max allows 15 repeaters for voice per site – nearly double the capacity, without needing to run 2 radio systems for large events.
If you don’t want all the costs of Capacity Max, but are willing to spend a little more than the cost of Capacity Plus, you can operate Capacity Max in Site Trunking Mode, without the Capacity Max System Server (CMSS), System Advisor and the integrated RM2 Radio Programmer, which does take away advanced features such as Multisite capabilities, but the point is you retain the call ringing, creating a more user friendly version of Capacity Plus.
