Installation and Maintenance Practice

2 Issue 4, February 2009 61180001L1#S-5D
Common Modules
The Common Modules supported by the Total Access
1500 are described below.
PSU/RGU
The Power Supply Unit/Ring Generator Unit (PSU/
RGU) receives –48 VDC from an external source to
provide all necessary voltages required by the other
common modules and channel units. Two PSU/RGUs
may be installed to provide fully redundant operation.
Through switch mode operation, either PSU converts
the incoming –48 VDC to regulated +5 VDC, +3.3
VDC and unregulated –7.5 VDC, –24 VDC, and –48
VDC for distribution to the other modules. Ring voltage
circuitry within the PSU generates 105 Vrms nominal,
20 Hz ring voltage for distribution to the channel bank’s
voice cards. Ring voltage is disabled by removing the 5-
amp GMT front panel fuse labeled 20Hz. The PSU/
RGU does not require provisioning prior to insertion
into the channel bank.
SCU
The System Controller Unit (SCU) provides network
management capability for the channel bank. The SCU
is used to provision, test, and determine status for any
module in the channel bank. It is also available in COT
and RT versions with Mechanized Loop Testing. The
front panel has a craft interface, test equipment timing
output, alarm and status indicators, plus an ACO (Alarm
Cut-Off) switch.
LIU
The Line Interface Unit (LIU) terminates up to 4 T1
lines, with a separate T1 that is included for protection
switching with the Quad LIU or two T1 lines with the
Dual LIU. The LIU generates control signals and clocks
used by the channel units, and controls both manual and
remotely initiated T1 loopbacks. It detects alarm condi-
tions and reports the alarm status to the SCU. The front
panel has a dual bantam jack for T1 test access, status
LEDs, and a STATUS pushbutton.
Access Modules
Total Access 1500 incorporates a complete array of
local loop access technologies into an integrated intelli-
gence system. Most access modules occupy one slot in
the Total Access chassis.
The access modules supported by Total Access 1500 are
listed in the Total Access 1500 System Manual
(P/N 61180001L1#S-1). Refer to individual Installation
and Maintenance Practices and Job Aids for detailed
information on installation, testing, operation, mainte-
nance, and troubleshooting.
WARNING
If using two (redundant mode) List 2 Quad
LIUs (P/N 1180109L2) in the Total Access
1500 chassis, do not metallically connect the
T1 (DSX-1) to interfaces that connect to the
Outside Plant or its wiring. These interfaces
are designed for use as intra-building inter-
faces only. The addition of Primary Protectors
is not sufficient protection to connect these
interfaces metallically to OSP wiring.
It is permissible to connect the T1 (DS-1)
interface metallically to the OSP if only one
LIU (non-redundant mode) is to be used at any
time in the Total Access 1500 chassis.

Unpack and Inspect the Shelf
Each Total Access 1500 shelf is shipped in its own
cardboard shipping carton unless it was ordered as a
fully racked cabinet or wall mount system. Open each
carton carefully and avoid cutting too deep into the
carton with sharp objects.
Mounting the Shelf
The Total Access 1500 shelf can be flush-mounted or
mid-mounted.
Mounting Bracket Orientation
The Total Access 1500 shelf comes with mounting
brackets that can be mounted with the flanges facing
forward or backward in two different locations on the
shelf sides. Therefore, the rack can be flush-mounted or
mid-mounted. Attaching the mounting brackets to the
shelf requires four screws on each side, and are supplied
with the unit.
The following are the recommended ways to mount the
shelf:
• Flush-mount: To flush-mount a shelf in the rack,
use a #2 phillips-head screwdriver and attach the
mounting brackets (see Figure 2) with the flanges
containing the slotted rack-mounting holes facing
the front of the Total Access 1500 shelf. The
mounting brackets should be attached using the set
of mounting bracket holes closest to the rear of the
Total Access 1500 shelf.

• Mid-mount: To mid-mount a shelf in the rack, use a
#2 phillips-head screwdriver and attach the mount-
ing brackets (see Figure 3) with the flanges
containing the slotted rack-mounting holes facing
the rear of the Total Access 1500 shelf. The mount-
ing brackets should be attached using the set of
mounting bracket holes closest to the front of the
Total Access 1500 shelf.
Figure 3. Mid-Mount Bracket Orientation
Installing the Chassis
After attaching the mounting brackets to the Total
Access 1500 Chassis, use the appropriate screws for the
Central Office rack type and mount the chassis in the
rack as follows:
1. Flush-mount: For flush-mount systems, the Total
Access 1500 chassis must be mounted from the
rear of the rack, with mounting bracket flanges
facing rearward.
2. Mid-mount: For mid-mount systems, the Total
Access 1500 chassis 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 your CO.
Once the orientation of the chassis has been determined,
use four screws suitable to the CO rack and an appro-
priate screwdriver to secure the Total Access 1500
chassis in place on the rack.
Connections
Interconnections between the common card modules
and channel units are accomplished through the
backplane PCB. All external connections to the Total
Access 1500 are through connectors and wire-wrap
headers located on the backplane.
NOTE
When connecting power and ground wiring, be
sure to follow all local, national, and company
codes.
CAUTION

Frame Ground Connection
The frame ground terminal, located on the upper right
corner of the backplane (see Figure 4 and Figure 5),
should be connected using appropriately sized wire. Use
a wire gauge that is at least the same gauge as the power
wiring.
To make the frame ground connection to the Total
Access 1500, perform the following steps:
1. Using the crimping tool, connect an appropriate
lug to each end of the appropriately sized wire.
2. Connect the ground wire from Total Access 1500
Frame ground terminal to the Equipment Rack
grounding screw.
3. 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. Using a
ohmmeter, if applicable set to its the lowest resistance
range, place one lead on the rack’s ground strap and the
other lead on the Total Access 1500 frame ground
terminal. The reading should be 1 or 2 ohms. Greater
readings should be investigated.
Power Connection
NOTE
Connect to a reliably grounded –48 VDC
source, which is electrically isolated from the
AC source.
NOTE
A readily accessible disconnect device, such as
a rackmount fuse and alarm panel that is
suitably approved and rated, should be incor-
porated in the fixed wiring.
Power connections use a block, labeled TB1, located on
the upper right side of the backplane (see Figure 4 and
Figure 5). The terminals are on 0.375 inch centers and
allow for wire gauges up to 12 AWG. The Frame
Ground terminal routes to mechanical contact points
and provides an electrical connection to the chassis
metalwork. The power bus and frame ground route to all
the cards in the shelf.
The number of shelves that can be placed in a 7-foot
central office rack depends on the type of service
deployed and the number of access modules in the shelf.
After connecting and checking the ground to the Total
Access 1500 shelf, connect power to the shelf. Check to
make sure your power source is providing the correct
power and polarity to the shelf.
The following steps provide instructions on how to
connect power to the shelf.
1. Determine which fuse pairs are to supply power to
the Total Access 1500 shelf.
2. Remove the fuses from the A and B slots for the
pair.
3. The power terminal is labeled TB1. Cut four
lengths of appropriately sized wire to reach from
the terminals on the fuse and alarm panel to the
power terminals on the Total Access 1500 shelf.
4. Using the crimping tool, connect an appropriate
lug to each end of the wires.
5. Using a screwdriver appropriate for the fuse and
alarm panel terminals, and a straight slot or phillips
screwdriver for the Total Access 1500 power
terminal, connect the ends of one wire between the
“A” CO –48 VDC supply and the –48V PRI IN
terminal on the Total Access 1500 backplane.
6. Connect three more power wires, connecting the
“A” CO –48 VDC return with –48V PRI RTN; “B”
CO –48 VDC supply with –48 V SEC IN; and “B”
CO –48 VDC RTN with –48V SEC RTN.

Apply Power and Check Voltage
Before proceeding further, ensure that power has been
correctly applied to the shelf. The proper voltage to
Total Access 1500 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 shelf. There
will be power to pins on the backplane and
inside the shelf. Exercise caution to avoid
electric shock.
The chassis may be powered by multiple
power sources. Disconnect all sources prior to
servicing.
NOTE
The branch circuit overcurrent protection shall
be a fuse or circuit breaker rated for a
maximum of –48 VDC @ 5.0 A. Include the
appropriate input current rating for the
product.
1. Install appropriate fuses (5 amp max) in the slots in
the fuse and alarm panel that services the Total
Access 1500 shelf.
2. Using a voltmeter, place the common (normally
black) lead on the TB1 –48 V PRI RTN terminal
and the DC volts (normally red) lead on the TB1
–48 V PRI IN terminal. The reading should be in
the operating range of –42 VDC to –56 VDC, with
a nominal value of –48 VDC. Note the “negative”
polarity.
3. Using a voltmeter, test the connection using the
TB1 –48V SEC RTN terminal and the TB1 –48V
SEC IN terminal.
4. Remove the fuses from the fuse and alarm panel
slots that provide power to the Total Access 1500.
Ring Generator
The system operates with either an internal or external
ring generator. For external ring generator applications,
TB2 (see Figure 6) provides connections for ringing
voltage (pin 3), ringing return (pin 2), and frame ground
(pin 1).
Figure 6. Ring Generator Connector
Data Connections
An external composite clock input is required in the
Central Office Terminal (COT) when deploying digital
services from Total Access 1500.
NOTE
The 1180009L1 Dual LIU and the 1180109L1
Quad LIU have only one Composite clock
input. When using one of these LIUs, wire the
Composite clock to the Secondary Composite
CLKINS pins, and set the termination
dipswitch to the Secondary position (SW1,
CLK TERMS to IN and SW3, CLK TERMP to
OUT).
Also, when using either the 1180009L1 or
1180109L1 LIUs running multiple shelves off
of the same clock, wire the clock into the
Secondary clock input pins (CLKINS) and out
of the Secondary CLK output pins
(CLKOUTS).
The following steps provide instruction on how to wire
primary and secondary external composite clock to a
single Total Access 1500.
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.
3. Using the wire-wrap tool, wire wrap the “+” wire
from the clock source to the pin marked “+” on

4. Wire wrap the “–” wire from the clock source to
the pin marked “–” on connector P14, CLKINP.
5. Wire wrap the drain or shield wire from the clock
source to the pin marked as ground on connector
P14, CLKINP.
6. Tie the clock source wire neatly to the frame.
7. On SW3 mounted to the right of P14, move the
switch to the IN position.
8. Repeat steps 1 - 7 for secondary clock to connector
P14, CLKINS, but set SW1 to the IN position
instead of SW3 in step 7.
Figure 7 illustrates an individual Total Access 1500
shelf utilizing redundant timing.
Figure 7. Redundant Composite Clock Wiring
Up to 14 dual LIU systems or 28 single LIU systems
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 14 or 28 Total Access
1500 shelves. Use wire of the same type as was used for
the wire run from the CO clock source to the Total
Access 1500 shelf.
The following steps provide instructions for connecting
up to 14 or 28 Total Access 1500 shelves to a single
external timing source.
1. Determine the length of wire required to run from
the first shelf, connector P14, to the second shelf,
connector P14, which is to be wired in the same
daisy chain. Leave approximately 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 ground terminal
pins of connector P14, CLKOUTP, on the top of the
backplane.
4. Run the wire from P14 on the “source” shelf to
connector P14, CLKINP, on the “receiving” shelf.
5. Wire wrap the “+”, “–” of the wire run to the “+”,
“–” terminals of P14 on the “receiving” shelf.
6. Set SW3 on the “source” shelf to the IN position,
and Set SW3 on the “receiving” shelf to the OUT
position.
NOTE
In any daisy chain of Total Access 1500
shelves using a single timing source, only the
first shelf in the chain should have the SW3
switch set to IN. All the remaining shelves in
the chain should have SW3 set to OUT.
7. Repeat steps 1 - 6 for each Total Access 1500 shelf
that is to be interconnected on the single CO timing
source.
8. Repeat steps 1 - 7 for secondary clock.
NOTE
If connecting the secondary clock source, set
SW1 to the SW3 settings.
Figure 8 illustrates a daisy-chained composite clock
configuration.
External Clock Output
Because some applications may require the shelf to
provide source timing, an additional connection is
provided at P12 labeled LOCCK (+, -) to provide a
64 kHz composite clock output. This output clock can
be used as a timing source for up to 14 dual LIU systems
or 28 single LIU systems.
Wiring Test Access
A four-lead (T, R, I, and drain) common test access bus
is provided for metallic test access to all customer loops
and is labeled P6 on the backplane. If the Total Access
1500 being installed will use these testing features,
wiring will be required to gain access to the test leads.

Connect MLT
Metallic Loop test access is gained by wiring into the
connector P6, on the right side of the backplane.
The following steps are instructions for wiring the Total
Access 1500 for Metallic Loop test access.
1. After you have located the test loops and run them
to the Total Access 1500 shelf, use wire strippers to
strip approximately 1 to 1-1/2 inches from the test
leads.
2. Using the wire-wrap tool, wire wrap the central
office “T” and “R” leads to the Total Access 1500
Rand Tpins, respectively, on terminal P6.
3. Wire wrap the inhibit wire of the cable to the top
pin labeled Ion P6.
4. Wire wrap the drain wire of the cable to the bottom
pin labeled ground on P6.
5. Neatly tie down the test cable pair.
Alarm Connections
Alarming is dependent on how the Total Access 1500
system is configured. When the Total Access 1500 is
deployed in a single or dual T1 feed, the System Control
Unit (SCU) should be provisioned for D4 Conventional
Alarm Relay Mapping.
The alarm outputs will be designated as follows:
• VMJ (Visual Major)
• VMN (Visual Minor)
• AMJ (Audible Major)
• AMN (Audible Minor)
• AUX (Auxiliary)
•PWR
When deployed in a DLC configuration using a quad T1
feed, the SCU can be provisioned for T1 Mapping
which provides the following alarm outputs:
• T1A (A Digroup Major)
• T1B (B Digroup Major)
• T1C (C Digroup Major)
• T1D (D Digroup Major)
• BANK (Bank System Major)
•PWR
In the T1 Mapping mode, the Total Access 1500
separately monitors the performance of each digroup
(A, B, C and D) and the bank. The T1 Mapping mode
assures that an alarm at the digroup level provides
appropriate central office and remote information.
The Total Access 1500 provides standard bank alarm
outputs. Each of the alarms listed below consists of a
three-pin wire-wrap header that connects to the SCU for
alarm management. The SCU provides the necessary
electronic circuits for a NO/COM/NC contact
arrangement.
The alarms are as follows:
• Major-Visual Output
• Minor-Visual Output
• Major-Audible Output
• Minor-Audible Output
• AUX Output
The alarming configuration is selected as an LIU option
through the VT100 craft interface.
Connecting Alarm Outputs
Depending on the vendor equipment employed at the
CO, wiring external alarms from the Total Access 1500
shelf will vary slightly. The important consideration is
whether the external alarm equipment requires a
Normally Open (NO) or Normally Closed (NC) circuit
to pass an alarm. After determining what the CO
equipment requires, connection can be made to the
equipment from the Total Access 1500 shelf, see
Figure 9 for location of alarm contacts.

NOTE
Each three-pin alarm header is wired the same
way for the specified alarm.
The following steps are instructions for connecting
alarm outputs to the Total Access 1500.
1. Determine whether the external alarm reporting
device uses a normally open or normally closed
circuit for alarm relay.
2. Using standard telco cross-connect wire, determine
and cut the length required to reach from the alarm
headers to the alarm-reporting device.
3. Using wire strippers, strip 1 to 1-1/2 inches from
both ends of the wire.
4. Using a wire-wrap gun, wire wrap one strand to the
center pin (common) from the Total Access alarm
relay header, and the other strand to either the
“NO” (normally open) or “NC” (normally closed)
pin on the relay header.
5. Connect, using wire wrap or lugs, as appropriate,
the two wires to the appropriate terminals on the
external alarm relay device being used.
Connecting Miscellaneous Alarm Inputs
There are four external alarm inputs that can be reported
to the SCU on the Total Access 1500 shelf: AUX1,
AUX2, AUX3, and AUX4. Terminal B supplies a
–48 VDC source. Terminal A expects –48 VDC if an
alarm condition exists on the alarmed equipment.
The following steps should be used to connect an
external alarm input to the shelf:
1. Using a #1 phillips-head screwdriver, remove the
long, thin guard if it is not already off.
2. Choose an alarm header set from block, P13 or
P18, on the top of the Total Access 1500
backplane.
3. Using standard telco cross-connect wire, determine
and cut the length required to reach from the
alarmed piece of equipment to the chosen header.
Allow length for 1 to 1-1/2 inches of stripped wire
for wire wrap, and neat routing out from the Total
Access 1500 shelf.
4. Using wire strippers, strip 1 to 1-1/2 inches from
both ends of the wire.
NOTE
Omit step 5 if the alarmed piece of equipment
has its own source of –48 VDC and does not
need the –48 VDC feed from the Total Access
1500 shelf. The Total Access 1500 shelf
expects to see –48 VDC on pin A of the alarm
pair when an alarm condition exists.
5. Using a wire-wrap gun, wire wrap one wire to the
B pin of the Total Access 1500 alarm input header
(P13 or P18), and the other end to the alarmed unit
alarm terminal marked “B.”
6. Wire wrap one end of the second wire to the A pin
of the Total Access 1500 alarm header (P13 or
P18) and the other end to the appropriate
equipment alarm terminal.
7. Using a #1 phillips-head screwdriver, replace the
long, thin guard using the screws provided.
NOTE
Check with the equipment manufacturer for
exact alarm markings.
Network Management Connections
The Total Access 1500 shelf integrates onto the
backplane several different management ports to allow
for remote management of the shelf. The management
interface is on the System Controller Unit (SCU)
discussed in detail in the System Description section of
the Total Access 1500 System Manual.
Up to 32 shelves can be linked together on the RS-485
bus for management of those shelves from a single
management interface.
SW2, located in the upper center of the Total Access
1500, is used to enable/disable RS-485. There is also a
3-position wire-wrap header, P12, for the RS-485
interface.
Connecting the RS-485 Bus Between Shelves
Up to 32 shelves can be linked together for management
from a single shelf designated as host (the other shelves
will be configured as clients). This feature allows
conservation of valuable external management ports
within the CO, and provides local or remote
management for up to 32 shelves from the craft
interface on front of the host SCU, or from the remote
management port connections described in this section.

12 Issue 4, February 2009 61180001L1#S-5D
The following steps are instructions for connecting the
RS-485 bus between shelves.
1. Determine and cut the length of wire necessary to
reach from the RS-485 wire-wrap header, P12, in
the first shelf in the chain to the RS-485 wire-wrap
header, P12, in the second shelf. Remember to
allow for stripping the ends of the wire, routing the
wires out to the right side of the shelf to the frame,
and tying down in accordance with CO SOP.
2. Using the wire-wrap tool, connect the shielded,
twisted pair interconnect wire to the RS-485 wire-
wrap header, P12, on the host Total Access 1500
backplane. (See Figure 10).
3. Run the interconnect wire to the backplane of the
first client shelf. Using the wire-wrap tool, connect
the two conductors and ground of the interconnect
wiring to the RS-485 wire-wrap header, P12, on
the backplane of the client shelf. (See Figure 10).
4. SW2, located in the upper center of the Total
Access 1500, is used to enable or disable RS-485.
Enable SW2 by setting the switch to the EN
position.
If there are more shelves to be connected, repeat steps 1
- 4 for each shelf to be added to the chain. Each shelf
after the first will be a client shelf on the daisy chain. It
is important to note that there is only one shelf desig-
nated as host on any daisy chain of up to 32 shelves.
RS-232 SCU NMA Management Port
The Total Access 1500 can send and receive TL1
commands for NMA management over the X.25 packet
switched network. The Total Access 1500 SCU has a
built-in X.25 PAD, and the shelf is ready to connect to
the network. Access to the network is via a synchronous
RS-232 connector, J34, located in the upper middle of
the backplane. The following steps are instructions for
connecting the X.25 to the Total Access 1500.
1. Connect the DB-25 data cable male connector to
the MGMT port, J34, on the Total Access 1500
backplane.
2. Connect the other end of the data cable to the
designated port of the X.25 switch.
NOTE
The CO X.25 network administrator must
configure the X.25 switch for the Total Access
1500 shelf, accomplishing tasks such as
assignment of an LDN number for the shelf.
Connect 10Base-T
The Total Access 1500 can provide SNMP management
capability over Ethernet. Access to the network is via a
RJ-45 10Base-T connector, J33 located on the upper
right side of the backplane.
WARNING
The 10Base-T Ethernet interface must not be
metallically connected to interfaces which
connect to the Outside Plant or its wiring. This
interface is designed for use in intra-building
interfaces only. The addition of Primary
Protectors is not sufficient protection in order
to connect these interfaces metallically to OSP
wiring.
To connect the Total Access 1500 shelf to the Ethernet
ring, simply plug the male RJ-45 modular connector
into the female RJ-45 port on the Total Access 1500
backplane. When planning the cable run to the Total
Access 1500 shelf, be sure to allow enough cable for
routing the cable to the right from the backplane
connector to the frame, and for tie off in accordance
with CO SOP.
There are two provisional items in the SCU: Telnet port
and TCP/IP port. Specify the Telnet port to access
menus over the Ethernet, and specify the TCP/IP port to
issue TL1 commands.
Connect to PairGain Test Controller (PGTC)
Use a straight through 50-pin amp cable to connect the
PairGain Test Controller to the PGTC interface (P5) of
the Total Access 1500. The PGTC interface accepts a
female connector.
3. MAINTENANCE
The Total Access 1500 Chassis requires no routine
maintenance for normal operation.
ADTRAN does not recommend that repairs be
attempted in the field. Repair services may be obtained
by returning the defective unit to ADTRAN. For more
information, refer to Warranty and Customer Service
section for further information.
