PRI, Primary Rate Interface, is a telecommunications means of carrying numerous voice and data transmissions between point A and point B.  Dynamic PRI is a Primary Rate Interface type that is able to distribute voice communications and High Speed Internet on one sole connection.

This form of PRI is used for businesses that are operating at a small or medium sized capacity.  Through Cavalier’s Dynamic PRI system incoming and outgoing calls are handled on the same channels, on a call by call foundation.  There are eleven channels for voice services and one channel for data services.

Frame relay is a telecommunications service that is used for the transmission of data between local area networks (LANs) over a wide area network (WAN).  The data that is transmitted is sent through a digital signal in a relay of frames to one or more given destinations.  The data is sent from one or more end-points.

Frame relay is a cost-efficient service that is also capable of speeding up data transmission.  This type of service is used to carry out voice and data procedures and can be provided on T-carrier systems and fractional T-1 carriers.

Cavalier offers frame relay as one of its key business segment products.
