Adax provides the foundation for the A-bis Interface between the Base Station Controller and the Base Transceiver Station in GSM Networks. The Adax ACT card provides a high density yet cost-effective solution for running LAPD software, over which runs the BTS management. The ACT card offers 4 or 8 T1/E1 interfaces for maximum usage of slot space. The ACT card provides access to all DSO’s on a T1 or E1 trunk and therefore can provide up to 2,048 DSO’s, by using eight ACT8 cards in a system, increasing call capacity on a single platform. Multiple cards can be used in a system providing for a highly flexible and completely scalable solution.

The Adax ACT card is available in cPCI and PCI formats for flexibility in platform choice. The efficiency of the Adax cards ensures that minimal burden is taken off the host CPU, leaving most of the system available for running GSM applications.
