By turning to Entropia, Tachion was able to replace its 20 chips per DS3 port with one Entropia chip per DS3 port, greatly reducing overall board space. Entropia's other main benefit, as far as Tachion is concerned, is the on-chip support for both AAL1 and AAL2. Tachion's initial board designs were targeted at only AAL1 applications. But, using Entropia, Tachion was able to develop a board that could be implemented in either AAL1 or AAL2 settings, increasing the number of applications in which the line card could be used. Packaging Entropia will be supplied in a 432-ball enhanced BGA package.
