Important Safety Instructions

1. Read and follow all warning notices and instructions marked on the product or included in the

manual.

2. This product is intended to be used with a three-wire grounding type plug – a plug which has

a grounding pin. This is a safety feature. Equipment grounding is vital to ensure safe

operation. Do not defeat the purpose of the grounding type plug by modifying the plug or

using an adapter.

Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for the

presence of earth ground. If the receptacle is not properly grounded, the installation must not

continue until a qualified electrician has corrected the problem.

If a three-wire grounding type power source is not available, consult a qualified electrician to

determine another method of grounding the equipment.

3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of

the product and to protect it from overheating, these slots and openings must not be blocked

or covered.

4. Do not allow anything to rest on the power cord and do not locate the product where persons

will walk on the power cord.

5. Do not attempt to service this product yourself, as opening or removing covers may expose

you to dangerous high voltage points or other risks. Refer all servicing to qualified service

personnel.

6. General purpose cables are provided with this product. Special cables, which may be required

by the regulatory inspection authority for the installation site, are the responsibility of the

customer.

7. When installed in the final configuration, the product must comply with the applicable Safety

Standards and regulatory requirements of the country in which it is installed. If necessary,

consult with the appropriate regulatory agencies and inspection authorities to ensure

compliance.

8. A rare phenomenon can create a voltage potential between the earth grounds of two or more

buildings. If products installed in separate buildings are interconnected, the voltage potential

may cause a hazardous condition. Consult a qualified electrical consultant to determine

whether or not this phenomenon exists and, if necessary, implement corrective action prior to

interconnecting the products.

In addition, if the equipment is to be used with telecommunications circuits, take the following

precautions:

– Never install telephone wiring during a lightning storm.

– Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.

– Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

– Use caution when installing or modifying telephone lines.

– Avoid using a telephone (other than a cordless type) during an electrical storm.

There may be a remote risk of electric shock from lightning.

– Do not use the telephone to report a gas leak in the vicinity of the leak.

telephone network be included in the installation and operation manual. Specific instructions are

listed in the following sections.

United States

Notice to Users of the Public Switched Telephone Network

1. This equipment complies with Part 68 of the FCC rules. On the equipment is a label that contains,

among other information, the FCC registration number and ringer equivalence number (REN) for

this equipment. The label is located on the bottom of the Model 3810 and 3820 modems. This label

is located on the Model 3811’s circuit card assembly. If requested, this information must be

provided to the telephone company.

2. Page A of this manual contains the Universal Service Order Codes (USOC) associated with the

services on which the equipment is to be connected.

3. The Ringer Equivalence (REN) is used to determine the quantity of devices which may be

connected to the telephone line. Excessive RENs on the telephone line may result in the devices

not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs should

not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as

determined by the total RENs, contact the telephone company to determine the maximum RENs

for the calling area.

4. If the 3800 Series modem causes harm to the telephone network, the telephone company will

notify you in advance that temporary discontinuance of service may be required. But if advance

notice is not practical, the telephone company will notify the customer as soon as possible. Also,

you will be advised of your right to file a complaint with the FCC if you believe it is necessary.

5. The telephone company may make changes in its facilities, equipment, operations, or procedures

that could affect the operation of the equipment. If this happens, the telephone company will

provide advance notice in order for you to make the necessary modifications in order to maintain

uninterrupted service.

Notice to Users of the Canadian Public Switched Telephone Network

The Canadian Department of Communications label identifies certified equipment. This certification

means that the equipment meets certain telecommunications network protective, operational and

safety requirements. The Department does not guarantee the equipment will operate to the user’s

satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the

facilities of the local telecommunications company. The equipment must also be installed using an

acceptable method of connection. In some cases, the company’s inside wiring associated with a single

line individual service may be extended by means of a certified connector assembly (telephone

extension cord). The customer should be aware that compliance with the above conditions may not

prevent degradation of service in some situations.

Safety Instructions

F3810-A2-GB30-30 September 1998

Repairs to certified equipment should be made by an authorized Canadian maintenance facility

designated by the supplier. Any repairs or alterations made by the user to this equipment, or

equipment malfunctions, may give the telecommunications company cause to request the user to

disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power

utility, telephone line and internal metallic water pipe system, if present, are connected together. This

precaution may be particularly important in rural areas.

CAUTION

Users should not attempt to make such connections themselves, but

should contact the appropriate electric inspection authority, or

electrician, as appropriate.

The Load Number for this equipment is listed on the label on the modem. The Load Number (LN)

assigned to each terminal device denotes the percentage of the total load to be connected to a

telephone loop which is used by the device to prevent overloading. The termination on a loop may

consist of any combination of devices subject only to the requirement that the total of the Load

Numbers of all devices does not exceed 100.

If your equipment is in need of repair, refer to the procedures described on page A in the front of this

Overview

The COMSPHERE 3800 Series modems, a new

generation of full-feature, high-speed dial modems, offer

reliable asynchronous and synchronous operation over

dial- or leased-lines networks. The 3800 Series modems’

unique software defineability allows for the addition of

future enhancements, whether it is installing new features

or firmware upgrades.

Through its downloading capability, any 3800 Series

modem can be upgraded to the latest firmware, requiring

no new hardware investment or on-site personnel, and

little or no downtime. These modems support a wide

range of modulation schemes and offer control using

either AT commands, the user-friendly diagnostic control

panel (DCP) or the optional COMSPHERE 6700 Series

Network Management System (NMS). The NMS

performs extensive monitoring, testing, reporting, and

restoral functions to assist in managing your network.

High-speed data transfer and reliable throughput at

data rates as high as 19,200 bps (V.32terbo) over dial lines

is guaranteed by employing the latest techniques in ITU-T

V.42bis/MNP Class 5 data compression and ITU-T

V.42/MNP error correction. In addition to fast line speeds,

the modem can send data to the DTE at speeds as high as

115,200 bps.

The 3800 Series modem is extremely versatile when

used in modem pooling environments; it allows multiple

users to temporarily customize settings in the 3800 Series

modem, thereby permitting communication with the

calling modem. Upon disconnection, the 3800 Series

modem falls back to its original configuration settings and

resumes normal operation.

The modem’s compatibility with a number of dialing

methods and protocols, such as asynchronous AT

commands, ITU-T V.25bis dialing, EIA RS-366-A dialing

for carrier-mounted modems, and the user-friendly

diagnostic control panel (DCP), permits the 3800 Series

modem to be used in a variety of applications and

environments while also allowing control over modem

configuration, dialing, and diagnostics. The 3800 Series

modems offer four preset factory configurations

containing the most often used modem settings. These

factory presets provide quick configuration for any

asynchronous/ synchronous dial, synchronous leased, or

UNIXr hardware-based dial environments.

The 3800 Series family is available in three models:

the Model 3810, a 4-wire/2-wire standalone modem; the

Model 3811, a carrier- mounted version of the standalone

unit; and the Model 3820, a 2-wire standalone unit. All

three models offer a variety of modulation schemes and

network enhancements while still providing reliable,

high-speed data transmission using the latest in modem

technology.
