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 CodeE
* 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.

• The Telephone Company may make changes in its facilities, equipment, 
operations or procedures, that could affect the proper operation of your 
equipment. If they do, you will be given advance notice so as to give you an 
opportunity to maintain uninterrupted service.
• The Digital Key Telephones designed for use with this system are hearing aid 
compatible.
• This equipment is capable of providing users access to interstate providers of 
operator services through the use of access codes. Modification of this equipment 
by call aggregators to block access dialing codes is a violation of the Telephone 
Operator Consumers Act of 1990.

• 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 
(908) 699 6700 to obtain appropriate information to keep customer 
equipment upgraded.
DID Requirements
Allowing this equipment to be operated in such a manner as to not provide for proper 
answer supervision is a violation of Part 68 of the FCC Rules.  
Proper answer supervision is when:
A. This equipment returns answer supervision to the PSTN when DID calls are:
-  Answered by the called station
-  Answered by the attendant
-  Routed to a recorded announcement that can be administered by the 
CPE user
-  Routed to a dial prompt.
B. This equipment provides answer supervision on all DID calls forwarded to the 
PSTN. Permissible exceptions are:

-  a reorder tone is received 
						

							Chapter 1 - Requirements Section 300-Installation
1-4  DBS 576 (USA), issued 6/2/98 576-13-300
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.
