SICOFI
Coefficients Program (STS 2060)
2.1
Features

(Z, R, X, B, GR, GX)
Menu driven program surface
Graphic screen output for various SLIC/SICOFI transfer functions
Direct programming of SICOFI testboard STUT 2060
SLIC program parts for various standard SLICs included
Analog simulation program for modelling new user specific SLICs included
2.2
General Overview
The high flexibility of the SICOFI is based on a variety of user programmable filters, which
consist of analog gain adjustment AGR and AGX, digital gain adjustment GR and GX,
frequency response adjustment R and X, impedance matching filter Z and the transhybrid
balancing filter B.
To gain an optimum result within a given environment while observing existing prescriptions,
Siemens offers to the SICOFI user the software packet STS 2060, which performs the
calculation of the filter coefficients by using an overall optimizing approach.
Because of the modularity of the SICOFI software program, it is possible to use the SICOFI
together with
– transformer SLICs with series or transverse feeding
– fixed electronic SLICs (Boards and SLIC program parts are available from Siemens Semi-
conductor)
– new user specific SLICs
The STS 2060 software runs on any IBM-AT compatible PC under MD-DOS Version 3.0 or
later providing 640 Kbyte available RAM, a 1.2 Mbyte floppy disk drive, and the math
coprocessor 80287 (optional).
The STS 2060 software consists of the two major sections: SLIC program (SLIC.EXE) and
SICOFI program (SICOFI.BAT). A transfer file (SLIC.SLI) provides the interface between
these two programs. Instead of SLIC.EXE it is possible to use a special analog simulation
program (S.BAT) for modelling new user specific SLICs.
All the specific values concerning the SLIC and its external circuitry (physical data, filter
dimensions, ... ) are gathered in an input file SLIC.INP.
The SLIC program SLIC.EXE models the SLIC and its external circuitry in order to create a file
SLIC.SLI which contains their transmission characteristics.
SLIC.SLI is a transfer file (output/input file) between the SLIC program and the SICOFI
program to introduce the SLIC circuit data into the SICOFI program.
COUNTRY.SPE is an input file of the SICOFI program describing the customer's specification
(CCITT etc ... ) and measurement configuration parameters (e.g. termination impedance).
