• Description: Octal Transceiver for UPN Interfaces OCTAT-P
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

The programmable Signaling and CODEC Filter with 4 channels, PEB 2465, implements
4 t/r (a/b) interfaces to link analog voice terminals to PBX subscriber lines or analog PBX
trunk lines to public switches. An integrated Digital Signal Processor handles all the
algorithms necessary, e.g. transhybrid-loss adaption, gain, frequency response,
impedance matching. The IOM-2 Interface handles digital voice transmission, SICOFI-4
feature control and transparent access to the SICOFI-4 command and indication pins.
To program the filters, precalculated sets of coefficients are downloaded from the
system to the on-chip coefficient RAM. Thus it is possible to use the same line card in
different countries.
The SICOFI-4 is a CMOS device offered in a P-MQFP-64 package.
ISDN-Oriented Modular Interface (IOM
The IOM-2 interface is a four-wire interface which has been defined by the “Group of
Four”: ALCATEL, Siemens, Plessey and ITALTEL systems houses. It became a
standard interface for interchip communication in ISDN applications.
All ICs described above are compatible to the IOM-2 interface and operate from a single
5 V power supply (incl. SICOFI-4).
