Semiconductor Group
The new Siemens generation of highly integrated ISDN circuits enables design
engineers to decrease board size and thus PBX size and its production costs.
Figure 1-2 shows an example of a PBX for 16 ISDN and 16 analog subscribers with
4 trunk lines realized with a few highly integrated chips of the new Siemens family of PBX
and Line Card ICs: DOC, SICOFI-4, OCTAT-P and QUAT-S.
