Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or
included in the manual.
2. This product is intended to be used with a three-wire grounding type plug - a plug
which has a grounding pin. This is a safety feature. Equipment grounding is vital to
ensure safe operation. Do not defeat the purpose of the grounding type plug by
modifying the plug or using an adaptor.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for
the presence of earth ground. If the receptacle is not properly grounded, the
installation must not continue until a qualified electrician has corrected the problem.
If a three-wire grounding type power source is not available, consult a qualified
electrician to determine another method of grounding the equipment.
The dc configuration of this product is to be grounded by connecting an external wire
between the building ground and the equipment ground screw on the rear of the
power supply assembly. Consult a qualified electrician to ensure that the ground
connections are connected.
Safety Instructions
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable
operation of the product and to protect it from overheating, these slots and openings
must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product where
persons will walk on the power cord.
5. Do not attempt to service this product yourself, as opening or removing covers may
expose you to dangerous high voltage points or other risks. Refer all servicing to
qualified service personnel.
6. General purpose cables are provided with this product. Special cables, which may be
required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable
Safety Standards and regulatory requirements of the country in which it is installed. If
necessary, consult with the appropriate regulatory agencies and inspection
authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two
or more buildings. If products installed in separate buildings are interconnected, the
voltage potential may cause a hazardous condition. Consult a qualified electrical
consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action prior to interconnecting the products.
In addition, if the equipment is to be used with telecommunications circuits, take the
following precautions:
– Never install telephone wiring during a lightning storm.
– Never install telephone jacks in wet locations unless the jack is specifically designed
for wet locations.
– Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
– Use caution when installing or modifying telephone lines.
– Avoid using a telephone (other than a cordless type) during an electrical storm.
There may be a remote risk of electric shock from lightning.
– Do not use the telephone to report a gas leak in the vicinity of the leak.

Overview
AT&T Paradyne offers the COMSPHERE
3000 Series Carrier, Figure 1-1, assembly to support
high-density mounting of the following AT&T Paradyne
products in a central-site environment:
• Model 3151 Channel Service Units (T1 CSUs)
• Model 3161 Data Service Units/Channel Service
Units (T1 DSU/CSUs)
• Models 3511, 3551, 3611, and 3616 Data Service
Units (DSUs)
• Models 3811 and 3911 dial/lease modems
r
Features
The carrier provides a convenient assembly in which
you can install a combination of up to 16 T1 CSUs, T1
DSU/CSUs, DSUs, and/or dial/lease modems in a
space-efficient package for crowded computer/
communications room environments.
In addition to the 16 devices, a single carrier operates
with a power transformer unit, an optional fan module, an
optional Shared Diagnostic Control Panel (SDCP), and an
optional speaker panel (for use with Models 3811 and
3911 dial/lease modems only).
The number of devices that can be installed in a carrier
is reduced by one for each Time Division Multiplexer
(TDM) or Multichannel Multipoint (MCMP) circuit card
that is installed. A TDM or MCMP card (functioning as a
multiplexer or digital bridge) is physically attached to a
Model 3611 DSU and occupies a separate slot in the
carrier. For digital bridge applications, each DBM-V,
DBM-S, or DBM-D occupies a separate slot, as well.
The ac power distribution systems for the carrier
consist of a power transformer unit that contains two
transformers, each serving eight slots in the carrier. The
backplane distributes low-voltage ac power from the
transformers to each slot, and an individual power supply
on each DSU or dial/lease modem produces the regulated
dc voltage.
A carrier designed to operate from a –48 Vdc power
unit is also available. This unit, called the Central Office
(CO) Power Unit, consists of a single dc power module
with a fan and operates in Basic mode (the mode of
operation in which the single power module supplies
power to the entire carrier). An optional second power
module is available for the CO Power Unit. With the
optional second power module, the CO Power Unit can be
configured to operate in either the Redundant mode (the
mode of operation in which both power modules serve all
the slots in the carrier and if one power module fails, the
remaining power module assumes the entire load) or the
Independent mode (the mode of operation in which each
power module serves only eight consecutive slots –
Slots 1 through 8 or Slots 9 through 16 in the carrier). The
Shared Diagnostic Unit (SDU), which is contained in
Slot 0, is powered by both power modules. For more
information, see the COMSPHERE –48 Vdc Central
Office Power Unit Installation Guide.

COMSPHERE 3000 Series Carrier
Figure 1-1. COMSPHERE 3000 Series Carrier
An optional fan module for the ac carriers is available
to provide forced air cooling to dissipate heat generated
within the carrier. It is recommended that fully configured
carriers and cabinets be installed with fan modules to
extend the life of the equipment. Guidelines for fan
module provisions are listed in T able 3-1 of the Fan
Module Installation section in Chapter 3.
An SDCP is required for initial installation and for
testing of 3600 Series DSUs, 3151 T1 CSUs, and 3161 T1
DSU/CSUs and their options. Models 3811 and 3911
dial/lease modems can be installed using the SDCP or AT
commands from the attached DTE. The SDCP, in
conjunction with the SDU, allows up to eight
COMSPHERE 3000 Series Carriers to be managed from
one control panel. Models 3551, 3611, and 3616 DSUs
and Models 3811 and 3911 dial/lease modems are
managed by either the COMSPHERE 6700 or 6800 Series
Network Management System (NMS).
Within the carrier, the first slot (Slot 0) is reserved for
the SDU. The SDU provides the required interface that
daisy chains carriers together for NMS and/or SDCP
control. In a cabinet configuration, connectivity between
the DSUs in the individual carriers allows control of
compatible units in the cabinet through a single NMS
interface, a single SDCP, or both.
On the rear of the carrier is a pair of 50-pin connectors
(P21 and P22) that provide the following network
interfaces:
• Digital line interface for DSUs.
• Analog leased-line interface for dial/lease modems.
1-2 December 1994 3000-A2-GA31-80
Introduction
Network Interface Modules (NIMs) can be installed at
the rear of the carrier (when not occupied by an Auxiliary
Backplane) to provide the PSTN (dial) or switched
56 kbps digital service interface for both DSUs and
dial/lease modems. There are nine different NIMs. For a
list of the feature/part numbers of these NIMs, see
Appendix B of this manual.
Alternatively, you can install up to two Auxiliary
Backplanes at the rear of the carrier to allow Model 3151
T1 CSUs and Model 3161 T1 DSU/CSUs to provide an
interface between a T1 digital network and Customer
Premise Equipment (CPE).
A modular DSU or dial/lease modem is a circuit card
that contains “gold finger” contacts on the rear edge of the
card and is supplied with a rear connector plate. A rear
connector plate has two DTE connectors, a 25-pin
EIA-232 connector and a 25-pin CCITT V.35 connector.
It allows removal of a modular circuit card without
disconnecting the DTE cables at the rear of the carrier.
Also, there are connector modules which have six ports
and are supplied with the modular DSU-TDM or
Table 1-1
Technical Specifications for the COMSPHERE 3000 Series Carrier
DSU-MCMP circuit cards. These connector plates and
modules function as interfaces between the modular
circuit cards and the DTEs.
This manual describes the procedure for installing a
COMSPHERE 3000 Series Carrier into a COMSPHERE
72-inch cabinet. A COMSPHERE 72-inch cabinet with
available equipment-mounting dimensions of 63 inches
high by 19 inches wide has the capacity to hold up to six
carriers, allowing for a high-density installation
combination of up to 96 DSUs and/or dial/lease modems.
COMSPHERE 3000 Series Carriers can also be mounted
in other types of EIA standard 19- or 23-inch wide
cabinets. (The heights of the other types of cabinets may
vary.)

• Filler panels for empty slots.
• Applicable manuals
An equipment list is included at the end of this manual
to assist you in ordering any additional components you
may require.
Installation Considerations
Your installation site should be well-ventilated, clean,
and free of environmental extremes. There should be 2 to
3 feet of clearance at the front and rear of the cabinet in
which the carrier is to be installed to allow access for
installation of the power transformer unit, (optional) fan
module, and (optional) SDCP, as well as the network
interface connectors, rear connector plates, and DTE
cables.
• Power transformer unit.
• Fan module(s), if needed.
• SDCP .
• Speaker panel (for use with the Models 3811 and
3911 modems), if needed.
• One digital or leased network interface cable for
each of the eight DSUs or modems.
• TDM (and MCMP) and/or digital bridge interface
cables, if needed.
• One or two Network Interface Modules (NIMs), if
needed.
• One or two dial network interface cables, if needed.
• Connecting cables and cords. (For a complete list of
the available cables and cords, see Appendix B of
this manual.)
• Rear connector plates for optional pre-mounting.
(Modular devices are packaged with rear connector
plates, but you can also order rear connector plates
separately.)

Installation Planning
One COMSPHERE 72-inch cabinet can accommodate
up to six COMSPHERE 3000 Series Carriers. A cabinet
does not need to be fully populated with carriers, however.
There are several general rules to follow during
installation of the carrier.
1. If installing multiple carriers, install the lower one
first, and if installing a full cabinet of carriers,
install the carriers from the bottom of the cabinet
and work up. This provides the following:
a. Proper alignment for subsequent carriers.
b. Easier carrier installation since they can be
placed in the mounting and lowered onto the
mounting screws.
c. Easier connection of the DTE interface.
d. Proper cabinet balance. Bottom-up installation
keeps the cabinet from becoming top heavy.
2. You must mount carriers when they are empty.
If a carrier is installed in an EIA standard 23-inch
(wide) cabinet, however, the mounting brackets on the
carrier must be reversed before the carrier is mounted.
Carriers can be installed in either EIA standard 19- or
23-inch (wide) cabinets.
Models 3551, 3611, and 3616 DSUs and Models 3811
and 3911 dial/ lease modems within the COMSPHERE
3000 Series Carrier(s) can be managed from an SDCP, a
Network Management System (NMS), or both.
Remember that the Models 3551, 3611, and 3616 DSUs
and Models 3811 and 3911 dial/lease modems are
managed by the 6700 or 6800 Series NMS. A
COMSPHERE 3000 Series Carrier cannot be connected to
both a 6700 Series NMS and a 6800 Series NMS at the
same time.
The location of the SDCP within the cabinet should be
determined ahead of time. It should be installed at a
convenient level, usually at eye-level. In a fully
configured cabinet, this would be the fourth or fifth carrier
from the bottom. Note that the Model 3511 DSUs are not
capable of being managed by an SDCP.
The alarm output connection is closed, activating the
customer-supplied alarm, when any DSU or Model 381 1
or 3911 dial/lease modem in the carrier has an alarm
condition that lights the red Alrm LED of the DSU or
modem. For information on how to connect the alarm
output, see the Alarm Output Connection section in
Chapter 3.
Up to eight carriers can be controlled by an SDCP, but
there must be a Shared Diagnostic Unit (SDU) installed in
each carrier. (Slot 0 in each carrier is reserved for the
SDU.) The SDU provides the interface that connects the
SDCP to other carriers. Cabling is required that daisy
chains these interfaces together.
If the units in the carriers are to be managed from an
NMS, an SDU is required in all carriers. Up to eight
carriers can be daisy chained together.
Cooling requirements should be given consideration.
Depending upon the number of units in the carrier and
how they are equipped, a fan module may be
recommended. Table 3-1 in Chapter 3 will help you
determine whether or not you need additional cooling for
your carrier.
Two 50-pin connectors (P21 and P22) at the rear of the
carrier, each serving eight slots, provide the digital
interface for DSUs and the analog leased-line interface for
dial/lease modems. DSUs and dial/lease modems can be
placed in the same carrier, but they should be grouped
together, (e.g., eight DSUs with a digital interface and
eight dial/lease modems with an analog leased-line
interface).
2-33000-A2-GA31-80 December 1994
COMSPHERE 3000 Series Carrier
If modular devices are installed in the same carrier as
non-modular devices, the modular devices must be
installed to the left of all other devices, as viewed from
the front of the carrier.
If your carriers are equipped with DSUs with DBMs,
dial/lease modems, or modems having dial backup
capability, the half of the carrier containing those devices
must have a Network Interface Module (NIM) installed to
provide a dial network or switched 56 kbps digital service
interface. Since one module serves eight slots, it is best to
group units with dial capability.
NIMs can be installed at the rear of the carrier. There is
a total of nine different NIMs available.
The carrier’s backplane contains connectors which
automatically engage mating connectors on DSUs (and
TDM or MCMP circuit cards, if installed) or dial/lease
modems when they are installed. T o prevent accidental
contact with these connectors, use filler panels for unfilled
slots. Verify that you have ordered a sufficient quantity.
To use 3151 CSUs or 3161 DSU/CSUs in the carrier,
you must remove any rear connector plates or modules
and add the 3151/3161 Auxiliary Backplane. Using a
single Auxiliary Backplane, you can install any
combination of up to eight 3151 CSUs and 3161
DSU/CSUs on one side of the 3000 Series Carrier, and up
to eight 3600, 3800, and 3900 Series devices on the other
side of the carrier. Alternatively, using two Auxiliary
Backplanes, you can install up to sixteen 3151 CSUs or
3161 DSU/CSUs in a single 3000 Series Carrier.
For each non-modular TDM or MCMP circuit card
installed in the carrier, determine whether the circuit card
is to be used as a Time Division Multiplexer (TDM) or as
a digital bridge. A TDM interface cable is supplied with
each non-modular TDM or MCMP circuit card. However,
a digital bridge interface cable must be ordered separately.
For modular TDM or MCMP circuit cards, use
standard cables for Ports 1 through 6. However, a 6-port
V.35 interconnect cable is required for the 26-pin
high-density D-type connector on the connector module.
This cable must be ordered separately.
It is recommended that you do not perform any
procedure that removes power to the carrier (for example,
replacing the power transformer unit or disconnecting
power to the power transformer to install an SDCP in a
fully configured carrier) during peak operating hours since
disconnecting power disables all units in the carrier.

COMSPHERE 3000 Series Carrier
Overview
A COMSPHERE 72-inch cabinet is available for
mounting the COMSPHERE 3000 Series Carriers. Up to
six carriers can be mounted into a single cabinet. The
COMSPHERE 3000 Series Carriers can also be mounted
into other commercial EIA standard 19-inch and 23-inch
cabinets.
The COMSPHERE 3000 Series Carrier, Figure 3-1, is
designed to house T1 CSUs, T1 DSU/CSUs, DSUs,
DBM-Vs, DBM-Ss, DBM-Ds, TDMs, MCMPs, and
dial/lease modems. The carrier is a metal enclosure that
contains slots for installation of 17 circuit cards. The slot
labeled SDU (Slot 0) is reserved for the Shared Diagnostic
Unit (SDU); Slots 1 through 16 are for T1 CSUs, T1
DSU/CSUs, DSUs, DBM-Vs, DBM-Ss, DBM-Ds, TDMs,
MCMPs, or dial/lease modems. Under each slot number
(on the cover plate or SDCP) is a small area in which to
write the circuit channel identification numbers.
The carrier’s backplane contains connectors which
automatically engage mating connectors on the devices as
they are being installed. Filler panels (which must be
ordered separately) are required for unfilled slots.
Two 50-pin connectors (P21 and P22) at the rear of the
carrier (each serving eight carrier slots) provide an
interface between the carrier and the digital line for DSUs
and the carrier and the leased line for dial/lease modems.
Above these are connectors for the dial network
connections (P23 and P26). One or two network interface
modules (each serving eight carrier slots) can be ordered,
as needed, to establish dial network connections.
Figure 3-1. COMSPHERE 3000 Series Carrier Assembly
3-2 December 1994 3000-A2-GA31-80
Installation
There are nine NIMs available. The following NIMs
are used with the 3600 Series DSUs/DBMs:
• Permissive NIM (for use with V.32 and 2-wire
Switched 56 DBMs)
• Programmable NIM (for use with V.32 DBMs)
• 4-wire Switched 56 NIM (for use with 4-wire
Switched 56 DBMs)
WARNING
Do not connect a 2-wire
switched 56 kbps plug into an
RJ11C jack. This type of jack is
intended for analog PSTN
devices. Failure to do this may
cause equipment damage and
harm to the telephone network.
The following NIMs are used with the dial/lease
modems, or a combination of DSUs with V.32 DBMs and
dial/lease modems in the same carrier half:
• Permissive NIM (3911 only)
• Permissive NIM with the Make Busy feature
• Programmable NIM with the Make Busy feature
(3811 only)
• Permissive NIM with the Service Line feature
• Programmable NIM with the Service Line feature
(3811 only)
• Permissive NIM with both the Make Busy and
Service Line features
• Programmable NIM with both the Make Busy and
Service Line features (3811 only)
NOTE
You cannot use a NIM on the side of
the carrier where an Auxiliary
Backplane is installed.
Programmable mode corrects any loss in the transmit
signal level between the modem and the central office by
permitting the modem to transmit at the optimum signal
level. This is accomplished by the local telephone
company installing a resistor into the network interface
and is usually identified by an RJ45S-type jack.
Permissive mode is a standard dial-line connection and
is identified by the use of an RJ11C- or SJA48-type jack.
(The carrier also supports RJ21X- and RJ27X-type mass
termination interfaces for Permissive and Programmable
modes, respectively.)
The DDD NIMs, programmable and permissive, may
have Make Busy and Service Line as additional
capabilities. The Make Busy feature is useful when
modems are used in a ‘‘hunt” or ‘‘rotary” group. This
feature ties the Tip and Ring signals together so that the
modem appears busy. Make Busy is not used by DSUs
with DBMs, but using a NIM with this feature will not
affect the DBM’s performance. The Service Line feature
permits an extra dial line to be connected to a
COMSPHERE 3000 Series Carrier. NIMs with this
feature are identified by the two modular connectors
mounted on the NIM.
WARNING
The Make Busy feature must
only be used behind a PBX.
Connecting a NIM with the Make
Busy capability directly to the
PSTN is a violation of FCC
Part 68 Rules and Canadian
DOC CS-03 Regulations.
Non-modular DSUs equipped with TDM or MCMP
circuit cards are supplied with time division multiplexer
interface cables. If you plan to use the digital bridge
function, you must order a digital bridge interface cable.
When modular DSUs or modems are to be installed in
the carrier, rear connector plates or connector modules
must be installed at the rear of the carrier. Modular DSUs
and dial/lease modems are circuit cards that can be
removed from the front of the carrier without disturbing
the DTE cables attached to the rear connector plate at the
rear of the carrier. Also, there are connector modules that
are supplied with the modular DSU-TDM (or
DSU-MCMP) circuit cards. These connector plates and
modules function as interfaces between the modular
circuit cards and the DTEs.
A power transformer unit provides low voltage
ac power to the carrier’s internal power distribution bus.
A carrier designed to operate from a –48 Vdc power unit
is also available. This power unit is called the Central
Office (CO) Power Unit and it consists of one dc power
module. Note that an optional second power module is
available. For more information on the CO Power Unit,
see the COMSPHERE –48 Vdc Central Office Power
Unit, Installation Guide.
