1-2 Courier V.Everything Getting Started Guide
Features
x2 56-kbps Connectivity
If you have enabled x2, your Courier can connect at speeds up to
56 kbps. While line conditions may not always allow for 56 kbps
connections, the new Courier software allows you to achieve the fastest
analog speeds available.
Adaptive Speed Leveling to Adjust to Line Conditions
Adaptive Speed Leveling® (ASL) allows your Courier to monitor line
conditions while connected, and fall back to the next lower speed if
conditions are poor. Couriers also detect improved line conditions and
shift upward to the next higher speed. The transmit and receive channels
adapt independently, each detecting and adjusting to line conditions.
Caller ID Support
If you subscribe to Caller ID, your Courier can interpret and display
Caller ID information.
Calls to and from Modems and Fax Machines
When used with fax-capable communications software, your Courier
auto-detects and responds to calls from modems and Group III fax
machines using EIA-standard Class 1 or 2.0 fax software.
Carrier Loss Redial
If you enable the Carrier Loss Redial feature, your Courier will
automatically redial the last number it dialed if carrier is lost (for
example, if there is trouble on the line or if the remote modem hangs up).
This feature is useful for dialed-line connections that operate unattended.

Introduction 1-3
Dedicated and Leased-Line Support
You do not need to connect your Courier to the public switched telephone
network. You can connect a standard telephone cable between your
Courier and another modem and make connections without even dialing.
You can also connect your Courier to a line that you lease from the
telephone company.
Dial Security to Control Access to Your System
The Courier’s Dial Security feature allows you to control access at a
modem-to-modem level instead of using software that runs on the host
computer. With Dial Security, you can prevent unauthorized access to a
system through the use of password prompting and dial-back.
Distinctive Ring Support
If you subscribe to Distinctive Ring through your local telephone
company, your Courier can be set to recognize and respond to any of four
distinctive ring patterns.
Flash ROM Upgradability
Courier modems are software-upgradable using XMODEM file transfers
and U.S. Robotics Software Download (SDL) application, allowing you
quick, easy access to updates of your Courier’s technology. The latest
upgrades can be obtained on the U.S. Robotics web site or Bulletin Board
System.
Plug and Play Support for Windows 95
The software for the external and internal Courier has been developed to
support Plug and Play (as defined by the Plug and Play External and
Internal COM Device Specification, Version 1.00). When you connect your
Courier to a computer that uses a Plug and Play operating system, the
computer automatically detects and configure itself to the support your
Courier.
Remote Configuration and Diagnostics
You can remotely configure and test your Courier. If you are a network
administrator supporting remote users, this feature can save you time and
money.
