What is a Dynamic Integrated PRI?

• A Static integrated PRI has pre-determined or ‘fixed’ voice and data channels.
  
  
• A Dynamic PRI allows each of the 23 channels to be used for voice or data on an: as-needed basis.
  
  
• Example: If we only have two channels in use for voice calls, dynamic allocation will put the other 21 channels in the data mode to increase the data speed. As soon as a voice call is attempted, it automatically assigns a B channel for that call and reduces the data speed by 64K.
  
  
• In a nutshell, all channels are carrying data to increase bandwidth, but voice traffic has priority.
