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 modem’s 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.

SPEEDADJUST

Initial Speed Selection Adjustment Parameters

Defined Values For HSF

1 Byte  V90 speed adjust index. The index is actually a real number represented in a mantissa + exponent format where the 4 most significant bits (L) define the mantissa and the 4 least significant bits (R) define the exponent in negative form. This number limits the percentage of BLER allowed:
BLER limit = L*10^(-R) %
The higher the maximal allowed BLER is, the more aggressive the connectivity becomes, i.e. the connection rates tend to be higher. Typically, decreasing the exponent by 1 results in one rate higher connections. Note, that the above is very line dependent.
Examples:
Byte 41 defines the limit 0.4% (or 0.004)
Byte f1 defines the limit 1.5%
Byte f0 defines the limit 15%
The value of 0 indicates the default setting of the modulation, which may change from time to time.
