FCC Requirements
General Requirements
• The Federal Communications Commission (FCC) has established Rules which
permit the DBS 576 to be directly connected to the telephone network. FCC
Compliant standardized jacks are used for these connections.
• This equipment may not be used on coin service provided by the telephone
company. This equipment should not be used on party lines.
• Key FCC information appears in the following table.
Table 1-2. FCC information
• Before connecting the DBS 576, provide the telephone company with the
following information:
Designation Product Name Product Number
96 port Cabinet Base Cabinet VB-44020
96 port Expansion Cabinet Expansion Cabinet VB-44021
Item Specification
FCC Registration Number When used as a key system: JNVUSA-32340-KF-E
When used as a PBX: JNVUSA-32339-MF-E
Ringer Equivalence Number Loop start - 0.5B/2.8DC* ; DID - 0.0B*
Network Address
Signaling Code E
* The Ringer Equivalence Number (REN) is useful to determine the quantity of
devices that you may connect to your telephone line and still have all of those
devices ring when your number is called. In most, but not all areas, the sum of the
RENs of all devices on any one line should not exceed five (5). To be certain of the
number of devices you may connect to your line, as determined by the REN, you
should call your telephone company to determine the maximum REN for your call-
ing area.

576-13-300 DBS 576 (USA), issued 6/2/98 1-3
• When programming emergency number and/or making test calls to emergency
numbers:
- remain on the line and briefly explain to the dispatcher the reason for
the call.
- Perform such activities in the off-peak hours, such as early morning or
late evening.
• The software contained in the DBS 576 to allow user access to the network must
be upgraded to recognize newly established network area codes and exchange
codes as they are placed in service.
- Failure to upgrade the premises systems of peripheral equipment to
recognize the new codes as they are established will restrict the
customer and the customer’s employees from gaining access to the
network and to these codes.
- Bell Communications Research (Bellcore) publishes the North
American Numbering Plan (NANP) information in paper, microfiche
and tape. An abbreviated summary of the newly established area codes
and exchange codes is also available. Bellcore may be contacted on
[phone] to obtain appropriate information to keep customer
equipment upgraded.

T1 Requirements
This device must only be connected to the T1 network connected behind an FCC
Part 68 registered channel service unit. Direct connection is not allowed.
Environmental Requirements
Temperature: The environment should be free from excessive temperatures in order
to avoid component damage. Room temperatures should be 32°to 104° F (0°to 40°
C).
Humidity: The environment should be free from excessive humidity, which may
rust metallic parts and degrade performance. Do not install the system where
humidity could condense on its surfaces. Relative humidity should range between 30
and 90 percent.
Ventilation: Adequate ventilation must be provided to allow upward air circulation
through the cabinet grille.
Gas and airborne particles: To avoid corrosion or oxidation of electrical contacts,
the environment should be free from airborne particles and corrosive gas.
Electrical noise: The environment should be free from excessive electrical noise,
which could disturb the operation of digital circuits. The system should be located at
least 10ft. (3m) away from welders, dimmers, or other high-current machines.
Phones connected to the system should not be located near fluorescent lamps, air
conditioners, washing machines, TVs, or radios.
Vibration: The environment should be free from excessive vibration, which could
loosen components.
Water exposure: Because the DBS 576 is an electrical device, exposure to water is
dangerous. Do not place anything containing water on the system. Do not install
under overhead plumbing, sprinkler system valves, or in areas that are susceptible to
flooding.
Lighting: Sufficient lighting is required for testing and maintenance.
Lightning protection/grounding: The system must be properly grounded to protect
it from lightning damage.
• Supplemental and independent equipment grounding conductors are to be
installed between the system and the wiring system ground.
• One of the equipment grounding conductors must be a wire that is as thick or
thicker than the ungrounded branch-circuit supply conductors. The equipment
grounding conductor is to be installed as part of the circuit that supplies the
system and is to be connected to a ground terminal at the service equipment. Bare,
covered, or insulated grounding conductors should have a continuous outer finish
that is either green or green with one or more yellow stripes. The equipment
grounding conductor should be connected to a ground terminal at the service
equipment.
