STATUS
1. GENERAL
This practice provides installation and maintenance
procedures for the ADTRAN Total Access 1500 Dual
4-Wire Transmit Only (TO) Access Module. Figure 1
is an illustration of the Total Access 1500 Dual 4-Wire
TO.
Revision History
This is the initial release of this document. Future
revisions to this document will be explained in this
subsection.
General Description
The Dual 4-Wire TO Access Module is intended to be
deployed in the Total Access 1500 Chassis. The Dual
4-Wire TO provides for two individual 4-wire analog
interfaces between a VF transmission facility and the
Total Access 1500 Pulse Coded Modulation (PCM)
backplane. Each TO interface provides 4-wire
voice-grade (analog) data services with no signaling
associated with the circuit, or where signaling is
provided by in-band tones.

Features
The features of the Dual 4-Wire TO (P/N 1180212L2)
include the following:
• Two independent DC-isolated 4-wire VF channel
interfaces
• Extended operating temperature range from
-40ºC to +65ºC
• TLP transmit input range of +5.0 to -16.0 dBm in
0.1 dB increments
• TLP receive output range of +8.5 to -9.5 dBm in
0.1 dB increments
• Supports configurations for Sink, Source or No
Sealing Current
• Provisioning by craft interface or Site Manager
• Digital Loopback and 1004 Hz Digital Reference
Signal (DRS) Tone Tests via craft port or Site
Manager
• NEBS Level 3 and UL 1950 compliant

2. INSTALLATION
C A U T I O N
C A U T I O N
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
!
2. This device must accept any interference received,
including interference that may cause undesired
operation.
Remove the Total Access 1500 Dual 4-Wire TO from
the carton and visually ensure that damage has not
occurred during shipping or handling. If damage has
occurred, file a claim with the carrier, then contact
ADTRAN. Refer to Warranty and Customer Service
section of this practice.
The Dual 4-Wire TO inserts into any Access Module
slot (1 through 24) of the Total Access 1500 chassis.
To install the Dual 4-Wire TO access module, perform
the following steps:
1. Hold the unit by the front panel while supporting
the bottom side.
2. Align the card edges to the guide grooved for the
designated slot.
3. Insert the card until the edge connector seats
firmly into the backplane.
4. Push the ejector in place to ensure the unit is fully
seated.
Compliance
Table 1 shows the Compliance Codes for the Dual
4-Wire TO. The Dual 4-Wire TO complies with UL
1950, third edition. It is intended for installation in
restricted access locations only and in equipment with a
Type “B” or “E” installation code.
Changes or modifications not expressly approved by
ADTRAN could void the user’s authority to operate
this equipment.
Time Slot Assignments
For time slot assignments in the Dual T1 mode and in
the Quad T1 mode, refer to Table 2.
The Total Access 1500 platform can have multiple time
slots in the T1 data stream assigned to each physical
slot in the channel bank. The Total Access 1500 allows
craft selectable time slots using the electronic
provisioning interface. The system will automatically
map DS0s in the T1 as determined by the LIU
operational configuration. Manual mapping is available
via the LIU menu.
Connections
Four 50-pin male amphenol connectors on the rear of
the Total Access 1500 chassis provide the interconnect
wiring for each of the access module physical slots.
The Dual 4-Wire TO requires P1 (T/R) and P2 (T1/
R1) for the odd ports of each access module, while P3
(T/R) and P4 (T1/R1) for the even ports. See Table 2
for wiring interconnect details.

3. PROVISIONING
There are no hardware options in the Dual 4-Wire TO
access module; its specific options can be provisioned
from the Site Manager or from a DB-9 VT100 craft
port on the Total Access 1500 SCU. The factory
default settings for the Dual 4-Wire TO access module
are noted in Bold Text in Table 3.
Password and User ID
Password protection is factory disabled. If password
protection is enabled, then the SCU will display the log
on screen, and a valid user ID and password are
required to access menus. The factory default user ID
is USER, and the default password is PASSWORD
both are in all capital letters. Both the user ID and
password are required.

Front Panel LEDs
The Total Access 1500 Dual 4-Wire TO has two front
panel LEDs that provide status information for each
interface. See Table 4 for LED indications.
4. TEST FEATURES
Initiated Tests
The Dual 4-Wire TO supports a Digital Network
Loopback and 1004 Hz Tone Tests for each port to
support circuit turnup and maintenance efforts. These
tests are initiated from the Total Access Site Manager
or the Total Access 1500 Local Craft Port on the SCU,
and are initiated on an individual port basis.
Digital Network Loopback Test
The Digital Network Loopback provides a loopback
path for the DS0 data from the network. Received
data of the selected port is latched in on the appropriate
receive time slot on the receive bus, and then placed on
the transmit bus in the appropriate port’s transmit time
slot.
1004 Hz Tone Test
The 1004 Hz Tone Test generates a 1004 Hz @
0 dBm Digital Reference Signal (DRS) tone, which is
used to send DRS signal to the loop, to the network, or
to both simultaneously.
6. SPECIFICATIONS
Specifications for the Dual 4-Wire TO are detailed in
Table 5.
