FCC AND IC RFI INFORMATION

FEDERAL COMMUNICATIONS COMMISSION

AND

INDUSTRY CANADA

RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency energy and if not

installed and used properly, that is, in strict accordance with the manufacturer’s

instructions, may cause interference to radio communication. It has been tested

and found to comply with the limits for a Class A computing device in accordance

with the specifications in Subpart J of Part 15 of FCC rules, which are designed to

provide reasonable protection against such interference when the equipment is

operated in a commercial environment. Operation of this equipment in a

residential area is likely to cause interference, in which case the user at his own

expense will be required to take whatever measures may be necessary to correct

the interference.

Changes or modifications not expressly approved by the party responsible

for compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise emission from

digital apparatus set out in the Radio Interference Regulation of Industry Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites

applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le

brouillage radioélectrique publié par Industrie Canada.

FCC REQUIREMENTS FOR

TELEPHONE-LINE EQUIPMENT

1. The Federal Communications Commission (FCC) has established rules which

permit this device to be directly connected to the telephone network with

standardized jacks. This equipment is designed to operate only on dedicated

phone lines or wires. Do not connect to dial-up lines, coin lines, party lines, or

lines with dial tones.

2. If this device is malfunctioning, it may also be causing harm to the telephone

network; this device should be disconnected until the source of the problem

can be determined and until the repair has been made. If this is not done, the

telephone company may temporarily disconnect service.

3. If you have problems with your telephone equipment after installing this

device, disconnect this device from the line to see if it is causing the problem.

If it is, contact your supplier or an authorized agent.

4. The telephone company may make changes in its technical operations and

procedures. If any such changes affect the compatibility or use of this device,

the telephone company is required to give adequate notice of the changes.

5. If the telephone company requests information on what equipment is

connected to their lines, inform them of:

a. The telephone number that this unit is connected to.

b. The FCC registration number.

Item (b) can be found on the unit’s FCC label.

6. In the event of an equipment malfunction, all repairs should be performed by

your supplier or an authorized agent. It is the responsibility of users requiring

service to report the need for service to the supplier or to an authorized

agent.

CERTIFICATION NOTICE FOR EQUIPMENT USED IN CANADA

CERTIFICATION NOTICE FOR

EQUIPMENT USED IN CANADA

The Industry Canada label identifies certified equipment. This certification means

that the equipment meets certain telecommunications-network protective,

operation, and safety requirements. Industry Canada 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 (extension

cord). The customer should be aware that compliance with the above conditions

may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized maintenance

facility—in this case, Black Box. 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 lines, 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.

CHAPTER 2: Introduction

2. Introduction

The Modem 202T is a Bell 202 (CCITT V.23 optional) voice-band, 1200-baud

modem. Use it on private, leased, un-switched telephone lines or any dedicated 2-

or 4-conductor wire (twisted or untwisted, shielded or unshielded). The Modem

has a range of up to 20 miles (32.2 km) on any ordinary wire pairs or unlimited on

“loaded” telephone company voice-grade (VG-6) leased lines.

The Modem 202T can operate without handshake lines using the proprietary

DataSense (DSCC) microprocessor firmware. This feature detects and buffers

incoming RS-232 data to allow the assertion and stabilization of the FSK carrier

before transmitting the buffered characters.

The nominal operating supply voltage for the Modem 202T is 12 VDC via a

2-conductor screw terminal power connector.
