Preliminary
1
The S/T Bus Interface Circuit Extended (SBCX-X) implements the four-wire S/T interface
used to link voice/data ISDN terminals, network terminators and PBX trunk lines to a
central office. It is the successor of the SBCX PEB 2081 in 3.3 V technology.
The SBCX-X provides the electrical and functional link between the analog S/T interface
(compliant to the ITU recommendation I.430) and the IOM-2 interface.
It provides an S/T interface operating in TE, LT-T, LT-S, NT and intelligent NT modes, a
serial control interface (SCI) for host programming, three general purpose I/O pins and
one LED output which is capable to indicate the activation status of the S-interface
automatically or can be programmed by the host.
The SBCX-X is produced in advanced CMOS technology.
