To ensure compliance with FCC Part 15 Regulations, a ferrite choke must be installed

on the power transformer cable.

Procedure

To install a ferrite choke on the power transformer cable:

1. Open the ferrite choke, place it around the power transformer cable as close as

possible to the connector attached to the modem, and snap the ferrite choke shut.

2. Install a cable tie behind the ferrite choke to prevent it from sliding along the cable.

Communications Software Installation

A personal computer commands and controls a dial modem through communications

software. This software, which is installed on the PC, uses the AT command set to

send instructions to the modem.

The Model 3830 can be used with any standard communications software. Many of the

following procedures require that your communications software be running so you can

pass commands to the modem.

Modem Power-Up

Once your modem is properly connected to the DTE, dial or leased lines, and ac outlet,

press the modem’s rear panel power switch to the ON position. The modem begins a

power-up self-test in which all front panel LEDs momentarily light (note that this also

occurs on a reset of the modem), and the Power LED remains ON. The state of other

LEDs depends on your modem’s configuration.

On initial power-up, the modem is in Command mode. To verify that the modem is

connected and functioning properly, enter the following:

Type: AT

Press: Enter

The screen displays OK.

Selecting Factory Configuration Options

After the modem passes the power-up self-test, it can be configured for operation using

one of two factory preset configurations.

These factory preset templates contain the most commonly used configuration options

(straps) for Asynchronous Dial and UNIX hardware network configurations. Your

modem is shipped from the factory with the Async Dial default configuration options

stored in memory. If UNIX Dial is more appropriate for your configuration, then you

must change the factory setting as described as follows.

NOTE:

If you have already changed certain configuration options, you may have lost AT

command control. For example, operating in Synchronous mode or disabling AT

commands results in an inability to change configuration options. To regain AT

command control, refer to

Recovering AT Commands

for these procedures.

Procedure

To change a factory template:

1. Use the AT&F&W command to load the appropriate factory configuration to the

appropriate storage area. Enter the following:

Type: AT&F

where:

is one of the following factory configurations:

0 = Async Dial

3 = UNIX Dial

5 = Cellular (Mobile) (Valid only if ETC is installed)

6 = Cellular (PSTN) (Valid only if ETC is installed)

where:

is one of the following configuration areas:

0 = Active (Saved)

1 = Customer 1

2 = Customer 2

NOTE:

These three configuration areas are nonvolatile memory locations. Active (Saved)

contains the most recently saved changes to any configuration options. In the

event of power loss, the modem retrieves these configuration options. Customer 1

and Customer 2 are user-defined configuration areas.

2. Press Enter. The selected factory configuration is saved.

NOTE:

When configuring your modem, keep a record of its configuration options as a

future reference in case the modem must be replaced.

Recovering AT Commands

AT commands are issued from asynchronous terminals and personal computers.

Certain dialing methods, such as V.25bis and synchronous operation, disable the use

of AT commands and place the modem into a state known as Dumb mode. The

Model 3830 is capable of normal operation when in Dumb mode. However, if the setting

of a configuration option must be changed, it can only be accomplished using an AT

command.

The AT Recovery command (AT***) places the modem into a temporary state that

restores AT commands. When in this state, the modem’s previous settings are retained

except for the following configuration options:

HThe DTE Dialer Type configuration option (&M and &Q) is set to AT

HThe Async/Sync Mode configuration option (&M and &Q) is set to Async

HThe DSR Control configuration option (&S) is set to Forced On

HThe LSD Control configuration option (&C) is set to Forced On

If these settings are not appropriate, then change them to a setting compatible with

your current application.

The procedures for an AT recovery using an asynchronous terminal or personal

computer are listed in the following section. Read through these procedures before

performing a recovery:

"Procedure

1. Turn the modem Off and then ON. The modem performs a power-up self-test in

which all LEDs light. While this is running, repeatedly press the A key of your

DTE’s keyboard (or keep the key depressed if your keyboard automatically repeats

characters that way). Keep doing this until A’s (or a’s) appear on your DTE screen.

(You may use all uppercase or all lowercase characters.)

At least three consecutive A’s must be entered within a 2-second time interval.

If these characters are not echoed back to the DTE screen after the power-up

self-test is complete, then the modem is still in Dumb mode and maintains its

current configuration. Turn the modem Off and then ON again, and repeat Step 1.

2. Once the characters are echoed back to the DTE,

Type: T***

(The case of this character must be consistent with the case used in Step 1. Mixed

case prefixes such as aT or At are not recognized.)

This must be entered within 10 seconds after receiving the echoed characters.

Press: Enter

The screen displays OK.

The modem is now in AT Recovery mode, and remains in this state until a Save or

power reset occurs. While in this mode, you can use AT commands to make any

necessary changes to configuration options.

Keep in mind that the &C command is changed to Forced On (&C0), the &M and

&Q commands are changed to Async mode with AT commands enabled (&M0 and

&Q0), and the &S command is changed to Forced On (&S0). If these settings are

not appropriate, then reset them to a desired choice before exiting AT Recovery

mode.

3. To save changes, use the &W command:

Type: AT&W

where:

is one of the following configuration areas:

0 = Active (Saved)

1 = Customer 1

2 = Customer 2

Press: Enter

The modem exits AT Recovery mode and returns to its previous application

environment.

Initialization Strings

An initialization string contains several AT commands that are entered at once to

program the modem for a specific application. The factory default configuration options

are suitable for most applications.

The following initialization strings identify essential AT commands that directly impact

modem operation for a particular application. Replace the characters

with a value

suitable for your environment. If you need to further modify these strings for your

application, make sure additional commands are inserted somewhere in the middle of

the initialization string. Whenever an &L command is used, it must appear at the end of

an initialization string.
