(LAP-D), multiple IOM-2 and PCM interfaces, one up-to 40 MIPS DSP with on-chip
emulation and a Mailbox, one PCM-DSP interface for fast DSP access, one UART,
Interrupt Controller, …
The DOC is a CMOS device offered in a P-MQFP-160 package.
QUAT
S/T interfaces to link voice/data digital terminals to PBX subscriber lines and PBX trunk
lines to the public ISDN. It can handle up to four S/T interfaces simultaneously in
accordance with CCITT I.430, ETSI 300.012, and ANSI T1.605 standards.
The QUAT-S is a CMOS device offered in a P-MQFP-44 package.
OCTAT
U
OCTAT-P is an optimized device for LT applications and can handle up to eight U
interfaces simultaneously. It handles the U
interface specification except for the reduced loop length.
The OCTAT-P is a CMOS device offered in a P-MQFP-44 package.
SICOFI
implements 4 t/r (a/b) interfaces to link analog voice terminals to PBX subscriber lines
and 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 P-MQFP-64 package.
ISDN-Oriented Modular Interface (IOM
The “Group of Four”, ALCATEL, Siemens, Plessey and ITALTEL systems houses,
originally defined a General Circuit Interface (GCI) with the aim of specifying a
comprehensive interface which would allow various telecommunication devices to
communicate in an efficient manner. The IOM-2 interface is a four-wire interface. It
became a standard interface for interchip communication in ISDN applications. All above
ICs are compatible and operate from a single 5 V power supply (incl. SICOFI-4).
