Specifications

The Courier 1-7
Remote Configuration and Diagnostics
You can remotely configure and test the Courier. If you are a
network administrator supporting remote users, this feature can
save you time and money. Refer to Chapter 8, Remote Access, in
the Courier Modems Command Reference manual.
Adaptive Speed Leveling (ASL)
Couriers monitor line conditions while connected, and fall back
to the next lower speed—for example, 19.2K, then 16.8K in
V.32terbo mode—if conditions are poor. Couriers also detect
improved line conditions and shift upward to the next higher
speed. Transmit and receive channels adapt independently,
each detecting and adjusting to line conditions.
Calls to and from Modems and Fax Machines
When used with fax-capable communications software, the
Courier auto-detects and responds to calls from modems and
Group III fax machines, using EIA-standard Class 1 or 2.0 fax
software.
Testing
ITU-T V.54 loopback testing is available. The Courier can
perform analog, digital, and remote digital loopback tests. See
Chapter 15, Testing, in the Courier Modems Command Reference
manual.
Caller ID Support
The Courier can interpret and display caller ID information. See
the Caller ID section in Chapter 3, Dialing, Answering, and
Hanging Up, in the Courier Modems Command Reference manual.
Distinctive Ring Support
The Courier can be set to recognize and respond to any of four
distinctive ring patterns. See the Distinctive Ring section in
Chapter 3, Dialing, Answering, and Hanging Up, in the Courier
Modems Command Reference manual.
