ICs for Communications Octal Transceiver for UPN Interfaces OCTAT-P

Infineon Technologies 

PEB 2096

Overview

Enhanced Line Card Controller (PEB 20550), one SIDEC, 4-channel signaling controller

(LAPD), 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, Quadruple Transceiver for S/T Interfaces, PEB 2084, implements 4 four-wire

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®-P, Octal Transceiver for UPN Interfaces, PEB 2096, implements the two-wire

UPN interface used to link voice/data digital terminals to PBX subscriber lines. The

OCTAT-P is an optimized device for LT applications and can handle up to eight UPN

interfaces simultaneously. It handles the UPN interfaces in accordance with the UP0

interface specification except for the reduced loop length.

The OCTAT-P is a CMOS device offered in a P-MQFP-44 package.

SICOFI®-4, 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

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®-2)

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.
