What is a talkpath?


Capacity Max (and Connect Plus) uses Talkpath Licences to scale the system to the needs - and budget - of the customer. When designing or expanding a system, the number of Talkpaths required depends on a number of factors, including the following:

  • Is a dispatch application is used?
  • Is SIP used, if so, how many users would need to make and receive phone calls?
  • How many users are on the system?
  • What is the maximum number of simultaneous tallkgroup calls that would need to include the dispatcher?
  • Are private calls used and if so, how many of them would be made to dispatchers?
  • Is WAVE used? If so what is the size of the user base and traffic profile like there?
  • What is the traffic profile like on the radio system?

A talkpath can be seen as a trunk between a radio (or radio talkgroup) and an external voice application. In other words, a talkpath is a dynamically shared connection between a voice on the radio system and an external device. Or, you could even say that one talkpath is used for a call where one endpoint is in the radio system and the other endpoint is on something outside the system. Once the call has ended, that talkpath is free to be used for other calls.

Therefore the number of talkpaths must not be seen as the maximum number of calls the system can process, or somehow linked to this misconception.

The MOTOTRBO System Design Tools is an excellent tool for sizing a Capacity Max system. It also helps determine what equipment and licences are needed. This tool is available to Channel Partners on Motorola Online.
