ISDN Switches¶
ISDN Switches (or ISDN exchanges) were digital telephony exchanges supporting the ISDN protocol.
All major manufacturers of telephony switching equipment produced ISDN-capable switches at some point. In Germany, Alcaltel S12 and Siemens EWSD were the two widely deployed ISDN switches.
