1. GENERAL
The ADTRAN DDS Type 200 Dual Slot Housing is
used to house one or two standard T200 circuit
packs, and is capable of performing loop
termination. Figure 1 is an illustration of the unit.
Basic Features
The basic features of the unit are listed below.
• Standalone Type 200 housing
• -48VDC power connections
• Network connection through a terminal
barrier strip
• Customer connects to RJ-48S or barrier
strip
• Durable, hinged metal enclosure
• Wraparound transparent front panel for easy
LED viewing
The DDS T200 Dual Slot Housing is designed to
accept any standard Type 200 plug-in card. For
non-loop powered units, the DDS T200 Dual Slot
Housing can provide power to the circuit card
through an external power supply. The ADTRAN
1353.DSK48V02 power supply can be used to
provide -48 VDC from standard 100-120 VAC to
power these cards.
The ADTRAN 1353.POWER08 supply can be used
to provide -48 VDC from standard 220 VAC. These
power supplies must be purchased separately. The
T200 Housing also provides network and customer
interface connections to the circuit card.
Revision History
This is the third release of this document. This
practice has been reissued to include
Telecommunication Configuration Codes and
methods for locally powering the unit.
2. PHYSICAL DESCRIPTION
Figure 1 illustrates the ADTRAN DDS T200 Dual
Slot Housing with the cover on. Connections are
made available by unscrewing the lock screw and
lifting the hinged cover.
Inside the housing are Euro-style connectors,
illustrated in Figure 2, for connecting to the
network, to the CPE, and to an external power

source, if one is used. A grounding lug is provided
for frame ground connections.
The rear panel of the T200 Dual Slot Housing
contains two slots with RJ-48S jacks for CPE
connections and a portal for network and power
connections, illustrated in Figure 3.
The T200 Dual Slot Housing is 2 inches high by 6
inches wide by 9 3/4inches deep, and weighs less
than 1␣ pound. It can be mounted on a desk, table, or
wall. The unit operating temperature range is -40°C
to +70°C.
3. INSTALLATION
After unpacking the unit, immediately inspect it for
possible shipping damage. If damage is discovered,
file a claim immediately with the carrier, then
contact ADTRAN Customer Service. (Refer to
subsection 7, Warranty and Customer Service.)
Components shipped with the unit include the
following:
• T200 chassis (including RJ-48S jack)
• Four #8 screws
• Wall mounting template
The T200 chassis is designed to be wall- or
desk-mounted. For wall mounting, four #8 screws
have been included. Select a suitable position on a
wall or desk for installation.
Figure 4 illustrates the mounting pattern in the base
of the chassis. The four mounting screws should be
located as shown. Drive the screws into the
mounting surface, leaving a clearance of at least
1/4␣ inch, and no greater than 1/2inch.
A mounting template is provided with each unit to
assist in locating the drill holes. The template
attaches to the wall by a tape strip located across the
top of the template. Remove the template from the
wall after using.
Grounding Instructions (UL 1950)
In accordance with UL 1950, a supplemental earth
ground must be connected prior to connection of the
telecommunication wiring. The supplemental earth
ground connection shall be connected to the ground
lug.

Safety (Telephone Equipment) is provided in the
following paragraphs.
In addition to the power supply grounding
conductor, an equipment supplementary grounding
conductor that is not smaller in size than the power
supply grounding conductors, must be installed
prior to connection of telecommunications wiring.
In addition, the connection to the ground of the
supplementary equipment grounding conductors
shall be in compliance with the rules for terminating
bonding jumpers in Part K of Article 250 of the
National Electrical Code ANSI/NFPA 70.
Termination of the supplementary equipment
grounding conductor is permitted to be made to
building steel, to a metal electrical raceway system,
or to any grounded item that is permanently and
reliably connected to the electrical service
equipment ground.
The attachment plug receptacles in the vicinity of
the product or system are all to be of a grounding
type, and the equipment grounding conductors
serving these receptacles are to be connected to
earth ground at the service equipment.
Bare, covered, or insulated grounding conductors
are acceptable. A covered or insulated grounding
conductor shall have a continuous outer finish that is
either green, or green with one or more yellow
stripes.
4. CONNECTIONS
The terminal barrier strip is used to make
connections to the housing. To connect to the
barrier strip, place conductor into the receptacle of
each terminal. The terminal strip is connected to the
card edge connector to interface the connections to
the circuit card. Figure 2 illustrates the pinout of the
card edge connector in relationship to the barrier
strip. The RJ-48 jack, along with the terminal strip,
provides for CPE connection. Table 1 shows the
wiring connections. Table 2 shows the
Telecommunication Configuration Codes.
Power
The T200 Dual Slot Housing is designed to house a
loop-powered or locally-powered circuit card. The
terminal barrier strip provides the ability to connect
an external -48 VDC supply to the circuit card. One
of the following methods shall be utilized when
locally powering the unit:
