Introduction

This document refers to HSF (software) modem. Within the HSF modem are various family members; they are TWO-LINE, RIPTIDE, and WIRELESS.

The information applies to all modems, unless explicitly stated otherwise.

The HSF modem is a plug and play modem, which writes a set of parameters to the Windows registry upon installation. The registry information is copied from an INF file that exists on the HSF installation disk. The HSF INF file contains several sections, which get transferred to the registry. These include:

Country

OEM

Modem_HW

This document describes in detail all the elements that constitute the Country and OEM sections of the INF file. This will enable an HSF customer to modify modem parameters per country in order to satisfy country certification requirements and to adjust for OEM-specific hardware characteristics. Also, by replicating the Country structure, customers can add into the modem support for any number of countries provided the 64K limit imposed on INF file size is not exceeded.

Unless otherwise noted, all the values are entered in hexadecimal. The Microsoft registry format requires that the Most Significant Byte (in a 2-byte word) be stored first. For example, the T.35 value for USA is stored as B5 00.

Country Parameter Values

Location of Key in WINDOWS 9X Registry is

HKEY_LOCAL_MACHINE System CurrentControlSet Services Class Modem [XXXX] Country [YYYY]

[XXXX] - PnP modem key number

[YYYY] - Country key number

In the Country key is a Registry value called CURRENT which is a T35 Code that is used to declare which Country is to be used by the MODEM.

T35CODE

Parameter indicates the County Code of the country whose parameters are being specified.

Note: When setting this value to 0xFFFF in the INF, during installation, the Country Selection Application (CSA) will automatically define the modems T.35 Country Code to the Country of Use defined by the OS.

Defined Values

2 Bytes Defines T.35 Country Code (0-FE)

NAME

Parameter designates the ASCII name of the country specified by the T35CODE parameter.

Defined Values

CHAR[] - Defines Country Name (maximum length 30)

INTCODE

Parameter reflects the access code required in order to place an international call from the country of origin.

Defined Values

CHAR[] - International access dial code (maximum length 10)

TXLEVEL

Transmit Level Parameters

Specified values reflect negative numbers, i.e. a declaration of (0f)₁₆ in the INF file implies a value of -15 dBm and a declaration of (01)₁₆ implies a value of -1 dBm.

HSF accounts for a 3V configuration and a 5V configuration.

In the 3V configuration, DTMF transmit levels are in the range of -4 dBm to -11 dBm.

In the 5V configuration, DTMF transmit levels are in the range of 0 dBm to -7 dBm.

DTMF levels are in declared in 0.1 units i.e. a declaration of (28)₁₆ in the INF file implies a value of 4.0 dBm and a declaration of (14)₁₆ implies a value of 2.0 dBm.

*Parameter declared in the following format:

2 Bytes Defines the Center Frequency of the primary tone detector. Value represents the frequency in Hz.

2 Bytes Defines the Bandwidth of the primary tone detector. Value represents a range in Hz (with the Center Frequency in the middle. Tones within the specified range should be detected (e.g. if Center Frequency is 450 and the Bandwidth is 400, tones in the range of 250-650Hz are detected).

4 Bytes Defines primary filter Response Time. Value reflects the minimum time in milliseconds that takes the detector to detect a tone. Longer response time provides a more accurate tone detection. Normally, the default value for this parameter should not be changed.

2 Bytes Defines primary THRESHU. Value represents an upper limit level in dBm. If the

tone level that is being detected exceeds the value of THRESHU, then the tone detect flag is SET. This value will be overwritten by the values in the THRESHOLD country key. The value should be greater than the Response Time.

2 Bytes Defines primary THRESHL. Value represents a lower limit level in dBm. If the tone

level falls below THRESHL then the tone detect flag is RESET. This value will be overwritten by a value derived from the values in the THRESHOLD country key. This value should be greater than the Response Time.

4 Bytes Reserved.

4 Bytes Defines primary tone ON stability time. Value reflects the minimum time in milliseconds for which the modem must detect continuous tone in order for the Tone On event to be reported.

4 Bytes Defines primary tone OFF stability time. Value reflects the minimum time in milliseconds for which the modem must detect continuous tone non-existence in order for the Tone Off event to be reported.
