In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This is a driver supporting the Siemens chipset on various
ISDN-cards (like AVM A1, Elsa ISDN cards, Teles S0-16.0, Teles
S0-16.3, Teles S0-8, Teles/Creatix PnP, ITK micro ix1 and many
compatibles).

HiSax is just the name of this driver, not the name of any hardware.

If you have a card with such a chipset, you should say Y here and
also to the configuration option of the driver for your particular
card, below.
