Description
The Dual LIU is a common module for the Total Access
1500 chassis (P/N 1180001L1) or the Total Access
1500 19-inch chassis (P/N 1180019L1).
The Dual LIU connects the chassis to a T1 line at the
DSX-1 or DS1 level. All data formatting and line
encoding as well as backplane timing and control are
performed by the Dual LIU.

Installation Code (IC) A –
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
1. This device cannot cause harmful interference.
2. This device must accept any interference received,
including interference that can cause undesired
operation.
Changes or modifications not expressly approved by
ADTRAN could void the user’s authority to operate this

Instructions for Installing the Module
The Dual LIU plugs directly into the Total Access 1500
channel bank. No installation wiring is required.
The Dual LIU should be installed in the Total Access
1500 channel bank in the slot labeled
LIU-A or LIU-B.
Refer to Provisioning on page 4 prior to card insertion.
CAUTION
This release of the LIU software is designed to
operate with SCU software release V08 or later
to support feature enhancements. SCU
software can be found at www.adtran.com
under the Service/Support page.
To install the Dual LIU, perform the following steps:
1. If present, remove the LIU Blank (P/N 1180010L1)
from the appropriate LIU common module slot of
the Total Access 1500 chassis.
2 Issue 4, May 2006 61180009L1-5D
2. Hold the Dual LIU by the front panel while
supporting the bottom edge.
3. Align the Dual LIU card edges to the guide
grooved for the slot designated
LIU-A.
4. Insert the Dual LIU until the edge connector seats
firmly into the backplane.
5. Push the ejector in place to ensure the Dual LIU is
fully seated.
NOTE
An additional
LIU-B slot is also provided for
optional redundancy. For dual operation, only
Dual LIUs of the same software revision
should be installed.
Table 2. Front Panel LEDs
Label Condition Description
When the Dual LIU first powers up it performs the
power up self-tests, which check the DRAM and
checksum. Once the power up self-test is complete, the
status LEDs will reflect the true state of the hardware.
Front Panel LEDs
The front panel LEDs provide status and alarm information. See Table 2 for LED descriptions.
Front Panel Pushbutton
A pushbutton switch labeled
STATUS is accessible
from the front panel to aid in test and troubleshooting.

3. PROVISIONING
All options on the Dual LIU are provisionable either
manually, using internal DIP switches, or electronically
using the SCU
ADMIN port.
Windows HyperTerminal
Windows HyperTerminal can be used as a VT100
terminal emulation program. Refer to the Help section
of HyperTerminal for additional information.
Manual Provisioning
The DIP switches SW1 and SW2 provide the Total
Access 1500 with the necessary option settings for
DSX/DS1 modes of operation. Figure 2 shows the
orientation of the DIP switches. Ta bl e 3 on page 5
shows the available DIP switch settings.

Figure 2. DIP Switches
NOTE
DIP switch settings can be used for the initial
turn up of the system, and will automatically
assign time slots to physical slots, depending
on the setting selected. If any setting is
changed via the VT100 interface, the
REM
LED on the front panel will light indicating
that the settings have changed.
Electronic Provisioning
The craft ports on the Total Access 1500 SCU are used
to change default options and obtain access module
status through menu screens. To access the menu
screens, connect a VT100 terminal or computer running
a terminal emulation program to the SCU front panel
ADMIN port using a standard male RS-232, DB-9 cable.
ADMIN port settings are as follows:
• 9600 baud
• No parity
• 8 data bits
• 1 stop bit
• No flow control
NOTE
To ensure proper display background, select
VT100 terminal emulation under Settings.
Password and User ID
Password protection is a function of the SCU and is
factory disabled. If password authentication is enabled,
then the SCU will display the Logon screen. A valid
User Name and Password are required to access menus.
NOTE
The factory default User Name is “user”, and
the default Password is “password”. The User
Name and Password are not case sensitive.
Menu Navigation
To traverse through the menus, select the desired entry
and press
the
Enter. To work backward in the menu press
Esc key.
The menu tree in Figure 3 on page 6 illustrates the path
to every provisioning, performance, and test access
point in the Total Access 1500 Dual LIU menu.
Menus
The following subsections describe the Dual LIU menu
screens.
Main Menu
The LIU main menu provides access to the Dual LIU for
various functions such as viewing configuration, provisioning, viewing the current status of the module, setup
of alarms, testing, and performance monitoring.
Configuration Screen
The LIU Configuration screen is a read-only display. It
provides configuration data pertaining to the Dual LIU
and cannot be changed. Information such as unit name,
CLEI code, part number, product revision, and software
revision are displayed. Items such as Software Revision
will reflect new software revisions as upgrades are
performed.
