Cabinet Determination (DEFINITY Generic 1 and Generic 3)
DEFINITY Communications Systems G1 and G3 have a duplication option for the control cabinet
(that is, control circuits are duplicated).  These systems also have an option for duplicating the
expansion cabinet (that is, a second port cabinet can be added).  A DEFINITY system  is ordered
according to the need for duplication, the number of ports required, and future growth expecta-
tions.
For DEFINITY systems with multi-carrier cabinet(s), the cabinet that contains the control circuits
(duplicated or unduplicated) is called the Processor Port Network (PPN).  The PPN provides up
to 89 port slots.  If a second cabinet is required for additional ports,  the cabinet is referred to as
an Expansion Port Network (EPN).
Note:For G3r, the PPN is only supported by the multi-carrier cabinet.  EPNs in G3r can
use the single-carrier cabinets.
In a DEFINITY system with single-carrier cabinet(s), the stack of one to four cabinets that
includes the control circuits is called the PPN (G1 and G3i only).  The PPN also contains up to 64
port slots.  If an additional stack of one to four cabinets is required, the stack is referred to as an
EPN.
G1 and G3i systems that contain both a PPN and an EPN must be connected by way of expan-
sion interface circuits located in port slots in the PPN and EPN using fiber-optic cables.
The G3r uses a Center Stage Switch (CSS) for interconnections when there are  four or more port
networks (PPNs and EPNs).  In this case, each port networks TN570 Expansion Interface and
fiber module is connected by fiber-optic cable to a TN573 Switch Node Interface in a switch  node.
The CSS can consist of multiple switch nodes, in which case those switch nodes are intercon-
nected by fiber-optic cables.  When there are fewer than four port networks, the PPNs and EPNs
are connected in the same fashion as for G1 and G3i.  You can have a CSS for fewer than four
port networks, but it is not recommended unless you anticipate expanding the system to four or
more port networks.  The TN573 Switch Node Interface circuit packs are usually installed in the E
Carrier of the PPN.
Note:Although port networks can be interconnected using fiber-optic cable for G3r in the
same fashion as for G1 and G3i, it is more cost-effective and it is required, where
there are four or more port networks involved, to use the CSS.
The mixing of multi-carrier and single-carrier cabinets in an equipment configuration is allowed.
For example, a fully equipped multi-carrier PPN that requires a few additional ports can be sup-
plemented by one single-carrier EPN cabinet.  Such an arrangement would be more economical
than adding a multi-carrier EPN cabinet equipped with only one carrier.

Multi-Carrier Cabinet Configuration
A multi-carrier cabinet configuration can be selected from the following equipment arrangements.
The G3r data is given in the following table separately from the G1 and G3i data.
The G3r data has special considerations and limitations:
dThe PPN cabinet is the first cabinet and is available only in the multi-carrier cabinet.
dThe PPN cabinet supports only one port network.
dThe PPN cabinet is configured with three different carriers:
ÐProcessor Carrier - Minimum of one, maximum of two
ÐSwitch Node Carrier - One or two, depending on connectivity duplication
ÐPort Carrier - Minimum of one, maximum of four
dThe Switch Node Carrier can only be configured in a multi-carrier cabinet.
dThe EPN is available in both the single- and multi-carrier cabinet.

ENVIRONMENTAL REQUIREMENTS
General
This section provides information about the floor and wall space required for system  and associ-
ated peripheral equipment installed in the equipment room.  Specifications for temperature, humi-
dity, air purity, and lighting levels are also included.
Floor Plans and Layouts
Floor plan arrangements will vary depending on the size and shape of the equipment room and
the amount of growth planned for the system.  Typical floor plans are shown in Figures 10, 11,
12, and 13.  DEFINITY Generic 1  and DEFINITY Generic 3 can have either one system cabinet
(PPN) or two system cabinets (PPN and EPN) plus an auxiliary cabinet in some cases.
The wall behind the system cabinet must be clear of all objects (pictures, shelves, or windows)
that are not required in the system installation.  The entire area behind the cabinet must be
reserved for the cross-connect field and the cable access panel (when provided).  Also, room for
system growth should be considered.
Floor Loading
The type of system cabinet determines the floor loading requirement.
With Multi-Carrier Cabinet(s)
The floor must have a commercial floor loading code of at least 50 pounds per square foot.  A
fully loaded multi-carrier cabinet weighs about 800 pounds.  Thus, a free maintenance area of at
least 16 square feet is required for each cabinet.
With Single-Carrier Cabinet(s)
One single-carrier cabinet weighs about 130 pounds, a fully loaded two-cabinet system weighs
about 255 pounds, a fully loaded three-cabinet system weighs about 380 pounds, and a four-
cabinet system weighs about 500 pounds.  Since the floor must have a commercial floor loading
code of at least 50 pounds per square foot, a free maintenance area of at least 10 square feet is
required for a four-cabinet system.
103

Earthquake Protection
When earthquake or disaster bracing is required by law, or when local engineering feels that
bracing is necessary, the system cabinet can be bolted to the floor.  Figure 14 shows the zones
in the North American continent where bracing may be desirable.
Note:A greater susceptibility of an area to earthquakes is indicated by a higher number in
Figure 14.  In the United States, 0 represents the lowest susceptibility and 4
represents the highest.  In Canada, 0 represents the lowest susceptibility and 3
represents the highest.
Refer to the 
DEFINITYÒCommunications System Generic 1 and Generic 3ÐInstallation and
Test
, 555-230-104 manual for details regarding the installation of earthquake bracing.
Floor Space
The floor space requirements in the equipment room vary for each system.
With Single-Carrier Cabinet(s)
The following system equipment and optional peripheral equipment occupies floor space in the
equipment room (Figure 10):
dSystem Cabinet and Cable Slack ManagerÐThe system cabinet is 27 inches wide and
22 inches deep.  A single cabinet is about 20 inches high, a two-cabinet system is 39
inches high, a three-cabinet system is 58 inches high, and a four-cabinet system is 77
inches high.  The cable slack manager requires 38 inches between the cabinet and wall.
The system cabinets and cable slack manager occupy about 8 square feet of floor space.
With Multi-Carrier Cabinet(s)
The following system equipment and optional peripheral equipment occupies floor space in the
equipment room (Figures 11, 12, and 13):
dSystem Cabinet and Cable Slack ManagerÐThe system cabinet is 32 inches wide and
28 inches deep.  The cabinet is 70 inches high.  The cable slack manager requires 38
inches between the cabinet and wall.  Each cabinet (including the door opening) and
cable slack manager occupy about 22 square feet of floor space.
dAuxiliary CabinetÐThe auxiliary cabinet is 32 inches wide, 24 inches deep, and 70
inches high.  This cabinet (including the door opening and maintenance area behind the
cabinet) occupies about 22 square feet of floor space.
