premises applications. The Total Access 1500 System is
comprised of the chassis, common modules, and access
modules.
Trademarks: Any brand names and product names included in this document are
trademarks, registered trademarks, or trade names of their respective holders.
1
The Total Access 1500 19-Inch Chassis is 19-inches
wide by 3.50-inches high by 10.75 inches deep, and the
chassis mounts in a standard 19 or 23-inch wide rack.
The Total Access 1500 19-Inch Chassis and is made of
heavy gauge metal.
Common Modules
The common modules supported by the Total Access
1500 19-Inch Chassis 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 +3.3 VDC,
+5 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 modules. 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.
CAUTION
The Total Access 1500 19-Inch Chassis
requires the use of the List 3 and List 4 PSUs
(P/N 1180007L3, 1180007L4).
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
Central Office Terminal (COT) and Remote Terminal
(RT) versions with Mechanized Loop Testing. The front
panel has craft interface, test equipment timing output,
alarm and status indicators, plus an Alarm Cut-Off
(ACO) switch.
LIU
The Line Interface Unit (LIU) terminates up to four 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 conditions and reports the alarm status to the SCU.
2
The LIU front panel has a dual bantam jack for T1 test
access, status LEDs, and a STATUS pushbutton.
WARNING
If two (redundant mode) List 2 Quad LIUs
(P/N 1180109L2) are utilized in the Total
Access 1500 19-Inch Chassis, the T1 (DSX-1)
interfaces must not be metallically connected
to interfaces that connect to the Outside Plant
or its wiring. These interfaces are designed for
use as intra-building interfaces only. The
addition of Primary Protectors is not sufficient
protection in order 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 19-Inch Chassis.
Access Modules
The Total Access 1500 System incorporates a complete
array of local loop access technologies into an
integrated intelligence system. Most access modules
occupy one slot in the Total Access 1500 19-Inch
Chassis.
The access modules supported by Total Access 1500
System are listed in the Total Access 1500 System
Manual (P/N 61180001L1-1). Refer to individual the
Installation and Maintenance Practices and Job Aids for
detailed information on installation, testing, operation,
maintenance, and troubleshooting.

Frame Ground
Figure 4. Power and Ground Connectors
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 19-Inch Chassis, 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
19-Inch Chassis ground terminal on TB1 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 an
ohmmeter 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 19-Inch Chassis ground terminal
on TB1. The reading should be 1 or 2 ohms. Greater
readings should be investigated.
61180019L1-5A
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 modules in the chassis.
The number of Total Access 1500 19-Inch Chassis that
can be placed in a 7-foot CO rack depends on the type
of service deployed and the number of access modules
in the chassis.
After connecting and checking the ground to the Total
Access 1500 19-Inch Chassis, connect power to the
chassis. Check to make sure the power source is
providing the correct power and polarity to the Total
Access 1500 19-Inch Chassis. The following steps
provide instructions on how to connect power to the
chassis.
1. Determine which fuse pairs are to supply power to
the Total Access 1500 19-Inch Chassis.
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 19-Inch
Chassis.
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 19-Inch
Chassis 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 19Inch Chassis backplane.
6. Connect three more power wires, connecting the
“A” CO –48 VDC return with –48V PRI RTN; “B”
CO –48 VDC supply with –48V 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 Total Access 1500 19-Inch
Chassis. The proper voltage to the Total Access 1500
19-Inch Chassis is –48 VDC, with an operating range of
–42 VDC to –56 VDC.
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
19-Inch Chassis.
Ring Generator
The Total Access 1500 System operates with either an
internal or external ring generator. For external ring
generator applications, TB2 (see Figure 6) provides
terminal connections for ringing voltage, ringing return,
and frame ground.

Composite Clock Connections
An external composite clock input is required in the
COT when deploying digital services from the Total
Access 1500 System. The following steps provide
instruction on how to connect primary and secondary
external composite clock signals to a single Total
Access 1500 19-Inch Chassis.
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
connector P14, Clk in Pri.
4. Wire wrap the “–” wire from the clock source to
the pin marked – on connector P14, Clk in Pri.
5. Wire wrap the drain or shield wire from the clock
source to the pin marked as ground on connector
P14, Clk in Pri.

9. Set SW1 to the IN position (SW1 is the left-most
switch in the three switch cluster located to the
right of P14).
6. Tie the clock source wire neatly to the frame.
7. Set SW3 to the IN position (SW3 is the center
switch in the three switch cluster located to the
right of P14).
8. Repeat steps 1 through 6 for secondary clock to
connector P14, Clk in Sec (optional).

Figure 7. Daisy-Chained Composite Clock Wiring
8
Issue 1, May 2004
61180019L1-5A
Up to 14 dual LIU systems or 28 single LIU systems
may be daisy chained to a single output from the timing
source. This results in a requirement for only one wire
run from the timing source for an installation of up to 14
or 28 Total Access 1500 shelves. Use wire of the same
type as the wire run from the CO clock source to the
Total Access 1500 19-Inch Chassis. The following steps
provide instructions for connecting multiple Total
Access 1500 shelves to a single external timing source.
1. Determine the length of wire required to run from
the first chassis, connector P14, to the second chassis, connector P14. 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, Clk out Pri, on the top of
the backplane.
4. Run the wire from P14 on the “source” chassis to
connector P14, Clk in Pri, on the “receiving”
chassis.
5. Wire wrap the “+”, “–” of the wire run to the “+”,
“–” terminals of P14 on the “receiving” chassis.
6. Set SW3 on the “source” chassis to the IN position,
and Set SW3 on the “receiving” chassis to the OUT
position.
NOTE
In any daisy chain of Total Access 1500
shelves using a single timing source, only the
first chassis in the chain should have switch
SW3 set to IN. All the remaining chassis in the
chain should have SW3 set to OUT.
7. Repeat steps 1 through 6 for each Total Access
1500 shelf that is to be connected to the single CO
timing source.
8. Repeat steps 1 through 7 for secondary clock.
NOTE
If connecting the secondary clock source, set
SW1 to the SW3 settings.
Figure 7 illustrates a daisy-chained composite clock
configuration.
61180019L1-5A
Composite Clock Output
Because some applications may require the Total
Access 1500 System to provide source timing, an
additional connection is provided on P12 labeled Local
Clk (+, -) 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.
Mechanized Loop Testing Connections
A four-lead (T, R, I, and drain) common test access bus
is provided for mechanized loop test access to all
customer loops, labeled P6 on the backplane. Instructions for connecting the Total Access 1500 19-Inch
Chassis for mechanized loop test access are as follows:
1. After locating the test loops and running them to
the Total Access 1500 19-Inch Chassis, 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
19-Inch Chassis R and T pins, respectively, on
terminal P6.
3. Wire wrap the inhibit wire of the cable to the pin
labeled I on P6.
4. Wire wrap the drain wire of the cable to the pin
labeled ground on P6.
5. Neatly tie down the test cable pair.
Alarm Output Connections
Alarm interpretation is dependent on how the Total
Access 1500 System is configured. When the system is
deployed in a single or dual T1 feed, the SCU should be
provisioned for D4 Conventional Alarm Relay
Mapping. The alarm outputs will be designated as
follows:
•
•
•
•
•
•
VIS MAJ (Visual Major)
VIS MIN (Visual Minor)
AUD MAJ (Audible Major)
AUD MIN (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)
Issue 1, May 2004

• 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.
To connect alarm outputs to the Total Access 1500 19Inch Chassis, perform the following steps:
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.

P13
The Total Access 1500 19-Inch Chassis 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:
Connecting Alarm Outputs
Depending on the vendor equipment employed at the
CO, wiring external alarms from the Total Access 1500
19-Inch Chassis 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 19-Inch
Chassis, see Figure 8 for the location of alarm contacts.
Aux1
Figure 8. Alarm Contacts
4. Using a wire-wrap gun, wire wrap one strand to the
center pin (common) of 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 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 19-Inch Chassis:
Aux1 and Aux2 located on P13 and Aux3 and Aux4
located on P18. Terminal A expects –48 VDC if an
alarm condition exists on the alarmed equipment.
Terminal B supplies a –48 VDC source.
To connect an external alarm input to the Total Access
1500 19-Inch Chassis, perform the following steps:
1. Choose an alarm header set from P13 or P18 on
the Total Access 1500 19-Inch Chassis backplane.
2. Using standard telco cross-connect wire, determine
and cut the length required to reach from the
alarmed piece of equipment to the chosen header.
3. Using wire strippers, strip 1 to 1-1/2 inches of
insulation from both ends of the wire.
Issue 1, May 2004
61180019L1-5A
NOTE
Omit step 4 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 19-Inch Chassis. The Total Access 1500
19-Inch Chassis expects to see –48 VDC on
pin A of the alarm pair when an alarm
condition exists.
4. Using a wire-wrap gun, wire wrap one wire to the
B pin of the Total Access 1500 alarm input header,
and the other end to the external unit alarm
terminal marked “B”.
5. Wire wrap one end of the second wire to the A pin
of the Total Access 1500 alarm input header and
the other end to the external unit alarm terminal
marked “A”.
NOTE
Check with the manufacturer of the external
equipment for exact alarm nomenclature.
Network Connections
The Total Access 1500 System supports either DS1 or
DSX-1 network connections. The copper pair network
interface connects to the backplane at wire-wrap
connectors P7, P8, P9, P10, and P11.
Network Management Connections
The Total Access 1500 19-Inch Chassis integrates
several different management ports on the backplane to
allow for remote management of the chassis. The
management interface is on the SCU discussed in detail
in the “Section 1, System Description” of the Total
Access 1500 System Manual (P/N 61180001L1-1).
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 left center of the Total Access
1500 19-Inch Chassis backplane, is used to enable/
disable the RS-485 bus. There is also a 3-pin wire-wrap
header, P12, for connecting to 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
61180019L1-5A
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.
To connect the RS-485 bus between shelves, perform
the following steps:
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, wire routing, 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 wirewrap header, P12, on the host Total Access 1500
backplane. (See Figure 9).
3. Run the interconnect wire to the backplane of the
first client chassis. Connect the two conductors and
ground of the interconnect wiring to the RS-485
wire-wrap header, P12, on the backplane of the
client chassis. (See Figure 9).
4. Enable the RS-485 bus by setting switch SW2 to
the EN position.
If there are more shelves to be connected, repeat steps 1
through 4 for each shelf to be added to the chain. Each
shelf after the first will be a client shelf on the daisy
chain. Only one shelf is designated as host on any daisy
chain of up to 32 shelves.
RS-232 SCU NMA Management Port
The Total Access 1500 System 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 chassis 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 System.
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.
