1000 DSLAM Quad H2LIU (HDSL2 Line Interface Unit)

Installation and Maintenance

1. GENERAL

This section provides installation and maintenance

information for the ADTRAN Total Access 1000

Quad H2LIU (HDSL2 Line Interface Unit). Figure 1

is an illustration of the unit.

Revision History

This is the second release of this document. This

revision change was to incorporate new loop

requirements.

Features

The basic features of the Total Access 1000 Quad

H2LIU, List 1, P/N 1179109L1 include the following:

• Terminates up to four HDSL2 lines providing

an interface to the network.

NOTE

When using the Quad H2LIU to span power the

Total Access 1000 DSLAM the system may be

powered using two, three or four HDSL2 loops.

Deployment limits of the HDSL2 interfaces will

depend upon the service mix and cross-talk

environment of the feeder pairs used to provide

the HDSL2 service in a given installation. The

HDSL2 interfaces of the Quad H2LIU will

operate at a range of 7,500 feet of 26 AWG with

5 dBm of noise margin using the ANSI

T1.418-2002 crosstalk models. If it is desired to

deploy the Total Access 1000 DSLAM on two

HDSL2 interfaces, the DC loop resistance of

each loop should be less than 614 ohms which is

approximately 7,360 ft of 26 AWG cable. The

Total Access 1000 DSLAM can not in any

circumstance be powered by a single HDSL2

loop. When using two or more HDSL2 loops to

span power the Total Access 1000 DSLAM the

maximum difference in the DC resistance of any

two pairs should be less than 83 ohms, which

equates to approximately 1000 ft of 26 AWG

cable. The Adtran Quad H2LIU is only designed

to operate with 3

generation Adtran H2TUCs

(122300XLX, 1181113LX or equivalent).

Questions on the compatibility of the Total

Access 1000 Quad H2LIU and other H2TUCs

should be directed to Adtran Technical Support

at (800) 726-8863.

General Description

The ADTRAN Total Access 1000 Quad H2LIU is a

common card plug-in for the ADTRAN Total Access

1000 DSLAM. It connects the Data Access Terminal

to a HDSL2 line. All data formatting and line

encoding as well as backplane timing and control are

performed by the Total Access 1000 Quad H2LIU.

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,

and (2) this device must accept any interference

received, including interference that may cause

undesired operation.

Changes or modifications not expressly approved by

ADTRAN could void the user’s authority to operate

this equipment.

2. INSTALLATION

C A U T I O N

SUBJECT TO ELECTROSTATIC DAMAGE

OR DECREASE IN RELIABILITY.

HANDLING PRECAUTIONS REQUIRED.

After unpacking the unit, inspect it for damage. If

damage is noted, file a claim with the carrier, and then

contact ADTRAN. Refer to Warranty and Customer

Service.

The Total Access 1000 Quad H2LIU, List 1, plugs

directly into the ADTRAN Total Access 1000 Data

Access Terminal. No installation wiring is required.

The Total Access 1000 Quad H2LIU should be

installed in the Total Access 1000 Data Access

Terminal channel bank in the slot labeled LIU. When

installing the H2LIU in the Total Access 1000, grasp

the unit by the front panel and push the unit into the

connector until the unit is fully seated. Lock the unit

into position.

Compliance Codes

This product is intended to be installed in product

providing a Type “B” or “E” enclosure, and in a

Restricted Access Location. Table 1 shows the

compliance codes for the Total Access 1000 LIU.

Provisioning Options

All options on the H2LIU are provisionable

electronically using the craft interface on the ATM

BCU. See Figure 2.

Electronic Provisioning

The craft interfaces on the Total Access 1000 ATM

BCU 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

faceplate craft interface ADMIN port using a standard

male-to-male RS-232 DB-9 cable. Craft port settings

are as follows:

• 9600 Baud (default) (changeable to 19200 or

38400 in menus)

• No parity

• 8 Data bits

• 1 Stop bit

Windows HyperTerminal

Windows HyperTerminal can be used as a VT100

terminal emulation program. Open HyperTerminal by

selecting PROGRAMS/ACCESSORIES/

HYPERTERMINAL. Refer to the Help section of

HyperTerminal for additional questions.

NOTE

To ensure proper display background, select

VT100 terminal emulation under SETTINGS.

Password

The ATM BCU will display the log on screen, and a

valid user ID and password are required to access

menus. The factory default is ADMIN for the account

administrator, and PASSWORD for the password.

Menu Navigation

To traverse through the menus, select the desired entry

and press ENTER. To work backward in the menu

press the ESC (escape) key.

Front Panel Indicators

The front panel LEDs provide status and alarm

information. There are four LED indicators on the

LIU front panel, one for each HDSL2 network loop.

See Table 2 for LED indicators.

3. TESTING

Loopback Tests

Network Loopback

HDSL2 data is looped back toward the network with

framing and line coding unchanged.

Backplane Loopback

HDSL2 data is looped back toward both the network

and the customer. The network data is looped back

after it has passed through the framer and LIU

circuitry. The customer data is looped back

immediately upon entry to the LIU.

4. MAINTENANCE

The Total Access 1000 Quad H2LIU requires no

routine maintenance to operate properly. In case of

equipment malfunction, use the front panel indicators

to determine the trouble source.
