The Promina family of platforms provides an adaptive and reliable foundation on which to build wide area networks or interface to a broad range of carrier services.

Promina is the industry’s best access device for handling traditional voice and data applications in enterprise and government environments. Promina systems are characterized by their ability to support a broad range of user interfaces and network services.

The Promina BBS™ multiservice switch combines fully-featured ATM switching, an IP routing engine, and Ethernet termination within a unique hybrid IP and ATM architecture. This combination enables network operators to aggregate and adapt their legacy access network to high-speed ATM, IP and MPLS broadband cores and allows network providers to deliver enhanced customer services.

Advanced quality of service (QoS) technology is built into the BBS platforms.  The BBS QoS is based on the hybrid cell/packet architecture that enables the BBS platforms to maintain five layers of traffic shaping and preserve QoS across IP and ATM layers simultaneously. Combined with early packet detection (EPD) and partial packet detection (PPD), BBS can gracefully enforce Layer 2 class of service (CoS) while intelligently handling Layer 3 QoS and Diffserv requirements.
