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 standardi zed 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.

* 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 dete rmine the maximum REN for your calling area.

• 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 activitie s 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 esta blished 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.

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 sys tem valves, or in areas that are susceptible to
flooding.
Lighting: Suff icient lighting is required for testing and maintenance.
Lightning protection/groundin g: The system must be properly grounded to protect
it from lightning damage.

• One of the equipment grounding conductors must be a wire that is as thick or
thicker than the unground ed bran ch-circuit supply conductors. The equipment
grounding conductor is to be installed as part of the circuit that supplies the
system and is to be conn ected to a grou nd terminal at the ser vice equi pment. Bare,
covered, or insulated grounding conductors should have a continuous outer f inish
that is either green or green with one or more yellow stripes. The equipment
grounding conductor should be conne cted to a ground terminal at the service
equipment.

Cabinet Configurations
Two types of cabinets are used with the DBS 576. The DBS 576 base cabinet (VB-
44020) supports 96 ports. A DBS 576 system may contain up to two base cabinets.
Each base cabinet can be combined with up to 2 expansion cabinets (VB-44021) to
configure systems for up to 576 ports. They can also be combi ned with an existing
DBS to increas e the num ber of digit al exte nsion line ports. For det ails, see Chapter 4,
"Connection to DBS" (page 4-28).
