end in either stubs or 64-pin amphenol connectors
• If required, coaxial cable appropriate for DS3 or STS-1 network input to the Total Access
3000 Chassis
WARNING
To prevent electrical shock, do not install equipment in a wet
location or during a lightning storm.
CAUTION
Electronic modules can be damaged by static electrical discharge.
Before handling modules, wear an antistatic discharge wrist strap
to prevent damage to electronic components. Place modules in
antistatic packing material when transporting or storing. When
working on modules, always place them on an approved antistatic
mat that is electrically grounded.
Unpacking and Inspecting the Chassis
Each Total Access 3000 chassis is shipped in its own cardboard shipping carton unless it was
ordered as a fully racked system. Open each carton carefully and avoid puncturing the carton
with sharp objects. After pulling the chassis out of the carton, remove the foam endcaps and
slip the chassis out of the cardboard shipping sleeve and protective plastic bag.
After unpacking the unit, inspect it for damage. If damage is found, file a claim with the
carrier, then contact ADTRAN Customer Service. For more information, refer to “Appendix A,
Warranty”.

Installation
61181001L1-5E 5
Mounting Bracket Orientation
The Total Access 3000 Chassis comes with mounting brackets that can be mounted with the
flanges facing forward or backward in two different locations on the chassis sides providing
either flush-mounting or mid-mounting. Attaching the mounting brackets to the chassis
requires four screws on each side, and are supplied with the unit.
NOTE
Before installing the chassis in the Central Office frame the paint
must be removed and an antioxidant applied to the surfaces of the
mounting brackets that come in contact with the frame. This will
ensure electrical continuity between the Total Access 3000 Chassis
and the CO frame.
Flush-mounting
For flush-mounting, use a #2 phillips-head screwdriver and attach the mounting brackets to
the Total Access 3000 Chassis with the flanges facing rearward on the front mounting holes.
Mid-mounting
For mid-mounting, use a #2 phillips-head screwdriver and attach the mounting brackets to
the Total Access 3000 Chassis with the flanges facing forward on the front mounting holes.
Installing the Chassis
After attaching the mounting brackets to the Total Access 3000 Chassis sides, use the appro-
priate screws for the Central Office rack type and mount the chassis in the rack as follows:
Flush-mounting
For flush-mount systems, the Total Access 3000 must be mounted from the rear of the rack,
with mounting bracket flanges facing rearward.
Mid-mounting
For mid-mounting the Total Access 3000 must be mounted from the front of the rack, with the
mounting bracket flanges facing forward.
NOTE
Other orientations will require either mounting from the front or
rear, and depend on the rack type installed in the CO and the
standard operating procedures established by the CO.
Once the orientation of the chassis has been determined, use the four appropriate screws for
the CO rack and an appropriate screwdriver and secure the Total Access 3000 Chassis in
place on the rack.

POWER CONNECTIONS
The backplane contains all I/O connectors, control signal routing, and power routing, as well
as all necessary interconnections between access modules, the multiplexer cards and the
System Controller Unit (SCU). No wire wrapping for network or loop connections is necessary
for normal chassis operation. Additional wire-wrap terminals on the backplane accommodate
special modes, such as metallic loop testing and external alarm input. Detailed wiring
diagrams are provided later in this practice.
All permanent connections to Total Access 3000 Chassis are made on the backplane. Figure 2
illustrates the backplane and Figure 3 indicates the location of the power and ground connec-
tions.
Frame Ground Connection
The frame ground lug, located on the lower left corner of the backplane, can accommodate
from 8 to 14 AWG wire. When connecting the frame ground, use a wire gauge that is at least
as heavy as the power wiring.
NOTE
The ground wire exiting the chassis must be terminated with a UL
Listed grounding lug. The grounding lug must be a two-hole lug or
a one-hole lug that is used in conjunction with an anti-rotation
device. The surface of the lug that connects to the frame shall be
cleaned and an antioxidant applied. The same shall be done for the
surface of the frame or bus where the connection is to be made. An
approved thread-forming screw shall be used to connect the frame
ground connector to the frame or bus.

861181001L1-5E
Figure 3. Total Access 3000 Power Connections
To make the frame ground connection to Total Access 3000 Chassis, perform the following
steps:
1. Using an appropriate crimping tool and lug, fasten the lug to the ground wire.
2. Locate a nearby grounding screw on the equipment rack.
3. Secure the ground wire to Frame Ground using the lugged end of the grounding wire.
4. Cut the ground wire length to reach from the grounding lug on the rack to the Total
Access 3000 Chassis grounding terminal, located on the lower left corner of the
backplane. Leave enough slack to allow for tying to the rack, if required.
5. Using wire strippers, strip 5/8 inches of insulation from the grounding wire.
6. Insert stripped end of the ground wire into the copper Total Access 3000 grounding
terminal.
7. Tighten the ground connection securely with a straight-slot screwdriver.
Test Frame Ground Connection
To ensure a good ground, use a multimeter to check continuity between the frame grounding
lug and the rack grounding strap at the top of the rack. With the multimeter set to its lowest
resistance range, if applicable, place one lead on the rack’s ground strap and the other lead on
the Total Access 3000 Chassis frame ground terminal. The reading should be 1 or 2 ohms.
Greater readings should be investigated.
NOTE
The Ethernet port, Dual and Quad BNC ports, composite clock
ports, and any DSX-1 port must only be connected to intra-
building wiring.

Power Connection
NOTE
Connect to a reliably grounded –48 VDC source that is electrically
isolated from the AC source.
NOTE
A readily accessible disconnect device, such as a rack mount fuse
and alarm panel that is suitably approved and rated, should be
incorporated in the fixed wiring.
Dual power buses are provided with separate battery returns. Power connections use two
separate opposing blocks, labeled TS1 and TS2, located on the lower left side of the backplane
below the Pair 5 amphenol connector (see Figure 3). The terminals are on 0.4375 inch centers
and allow for wire gauges up to 10 AWG. There is a separate Frame Ground terminal, labeled
FR GND, located on the bottom left side of the backplane, and can accommodate up to 8 AWG
wire. The two power inputs, TS1 and TS2, are identical in function and can be used for
redundant power configurations. The Frame Ground terminal routes to mechanical contact
points and provides an electrical connection to the chassis metalwork. The two power buses
and Frame Ground route to all the cards in the chassis. Plug-in cards are responsible for any
necessary DC-DC conversion.
Figure 4 depicts how the Total Access 3000 Chassis can be powered from a typical dual-feed
fuse and alarm panel. Seven shelves are depicted. The number of shelves that can be placed in
a 7-foot central office rack depends on the type of service deployed, the number of access
modules in the chassis, and, in the case of HDSL or T1, the number of repeaters being
powered.
After connecting and checking the ground to the Total Access 3000 Chassis, connect power to
the chassis. Check to make sure the power source is providing the correct power and polarity
to the chassis. To connect power to the chassis, perform the following steps:
1. Determine which fuse pairs are to supply power to the Total Access 3000 chassis.
2. Remove the fuses from the Aand Bslots for the pair determined in the above.
3. Using a #1 phillips-head screwdriver, remove the Plexiglass cover to the power terminals,
labeled TS1 and TS2.
4. Cut four lengths of AWG 10 wire to reach from the terminals on the fuse and alarm panel
to the power terminals on the Total Access 3000 Chassis. Be sure to include enough
length to allow for tying the wire neatly to the frame as specified by CO SOP.
5. Using the crimping tool, connect an appropriate lug to each end of the wires.
6. Using a screwdriver appropriate for the fuse and alarm panel terminals, and a straight
slot screwdriver for the Total Access 3000 Chassis power terminal, connect the ends of
one wire between the “A” CO –48 VDC supply and the –48 VDC –48 PRI terminal on the Total
Access 3000 backplane. Secure the wire to the backplane with wire tie through the tie
anchor.

7. Connect three more power wires, connecting the “A” CO –48 VDC return with TS1 –48 VDC
RET; “B” CO –48 VDC supply with TS2 –48 VDC –48 SEC; and “B” CO –48 VDC return with
TS1 –48 VDC RET. Secure the wires to the backplane with wire tie through the tie anchor.
NOTE
See Figure 4 for an example of multiple shelves powered by a single
equipment bay fuse panel.
Apply Power and Check Voltage
Before proceeding further, ensure that power has been correctly applied to the chassis. The
proper voltage to Total Access 3000 Chassis is –48 VDC, with an operating range of –42 VDC
to –56 VDC.
WARNING
Installing fuses in the fuse alarm panel at this stage will provide
power to the chassis. There will be power to pins on the backplane
and inside the chassis. Exercise caution to avoid electric shock.
NOTE
The branch circuit overcurrent protection shall be a fuse or circuit
breaker rated for –48 VDC at 20 amps. Include the appropriate
input current rating for the product.
1. Install the 20 amp fuses in the slots in the fuse and alarm panel that service the Total
Access 3000 Chassis.
2. Using a voltmeter, place the common (normally black) lead on the TS1 –48 VDC RET
terminal and the DC volts (normally red) lead on the TS1 –48 VDC –48 PRI terminal. The
reading should be in the operating range of –42 VDC to –56 VDC, with a nominal value of
–48 VDC. Note the “–” polarity.
3. Using a voltmeter, repeat step 2, using the TS2 –48 VDC RET terminal and the TS2 –48 VDC
–48 SEC terminal.
4. Remove the fuses from the fuse and alarm panel slots, securing power to the Total Access
3000 Chassis.

DATA CONNECTIONS
Removing Rear Plastic Guards
The large rear Plexiglass guard covering the backplane is a safety feature of the Total Access
3000 designed to keep personnel and equipment from contacting potentially high voltage
exposed at some backplane locations. Following the sequence of steps outlined in this practice
will allow the service provider to remove the guards once, make all the necessary Total Access
3000 Chassis backplane connections, and then reinstall the guards. To remove the guards,
perform the following steps:
1. Using a #1 phillips-head screwdriver, remove the long, thin Plexiglass guard covering the
wire-wrap terminals at the bottom of the backplane. It is held in place with two screws.
2. Carefully remove the guard by pulling it straight from the backplane.
3. Using a #1 phillips-head screwdriver, remove the four screws holding the large guard in
place.
4. Carefully remove the large guard by pulling it straight back from the backplane.
NOTE
Wire tie anchors are pre-installed on the Total Access 3000 Chassis
backplane to secure the 64-pin amphenol connectors. It is easier to
thread the wire ties through the anchors while the backplane
guard is removed. ADTRAN recommends using the wire ties
provided to secure the amphenol connectors. Thread the wire ties
through the anchors at this time, with the guard removed.
Wiring Clocks
The Total Access 3000 Chassis accepts either BITS or composite clock inputs from an external
timing source. When deployed as a DSLAM system, an optional Stratum 3E Clock Module
(P/N 1181930L1) can be used as a timing source that provides a backup clock signal. The
module works in conjunction with the DS3 Cell Switch Module (CSM) to provide holdover
capability upon the loss of the primary timing source, typically an external DS1 BITS clock. As
an Office Repeater Bay deploying HDSL or T1, no clock input is required. As an Office
Repeater Bay deploying ISDN, a composite clock input may be used. Future services may
require these or other clock inputs; the Total Access 3000 Chassis can accommodate them.
Connect 64 kHz Composite Clock
An external composite clock input may be used when deploying ISDN from Total Access 3000
Chassis. To wire an external composite clock to a single Total Access 3000 Chassis, perform
the following steps:
1. Determine the “+”, “–” and drain or ground wires from the CO clock source.
2. Using wire strippers, strip 1 to 1-1/2 inches of the insulation from the end of the clock
source twisted pair, shielded, drop wire.

Data Connections
61181001L1-5E 13
3. Using the wire-wrap tool, wire wrap the “+” wire from the clock source to the pin marked
“+” on connector P10, EXTCLK A-IN.
4. Wire wrap the “–” wire from the clock source to the pin marked “–” on connector P4,
EXTCLK A-IN.
5. Wire wrap the drain or shield wire from the clock source to the pin marked Son connector
P4, EXTCLK A-IN.
NOTE
If the drain or shield is connected to the clock source, then the
drain or shield does not need to be connected to the Spin of P4.
6. Tie the clock source wire neatly to the frame.
7. On the daughterboard mounted to the left of, and slightly below, P4, move the jumper so
that the left two pins labeled TERM IN, are connected together.
Up to eight Total Access 3000 Chassis may be daisy chained to a single output from the
timing source, so only one wire run is required from the timing source for an installation of up
to eight Total Access 3000 Chassis. Use wire of the same type as was used for the wire run
from the CO clock source to the Total Access 3000 Chassis. To connect up to eight Total
Access 3000 Chassis to a single external timing source, perform the following steps:
1. Determine the length of wire required to run from the first chassis, connector P4, to the
second chassis, connector P4, that is to be wired in the same daisy chain. Leave approxi-
mately 1 to 1-1/2 inches for wire wrapping.
2. Using wire strippers, strip approximately 1 to 1 -1/2 inches from both ends of the wire
run.
3. Using a wire wrap tool, wire wrap the “+”, “–” and drain wires to the “+”, “–” and “S”
terminal pins of connector P4, A-IN, on the backplane.
4. Run the wire from P10 on the “source” shelf to connector P4, EXTCLK A-IN, on the receiving
shelf.
5. Wire wrap the “+”, “–” of the wire run to the “+”, “–” terminals of P4 on the receiving shelf.
6. On the daughterboard of the receiving shelf, mounted to the left of, and slightly below P4,
move the jumper so that the right two pins, labeled TERM OUT, are connected together.
7. Repeat steps 1-6 for each Total Access 3000 Chassis, up to a total of eight in the daisy
chain, that is to be interconnected on the single CO timing source.
NOTE
In any daisy chain of Total Access 3000 Chassis using a single
timing source, only the first shelf in the chain should have the
timing daughterboard jumpered to TERM IN. All the remaining
chassis in the chain should have the daughterboard jumpered to
TERM OUT.
