1 DESCRIPTION

The Remote Test Access Unit (RTAU) (Figure 1) provides maintenance functionality for

monitoring and intrusive test access to the DS1 channels in the chassis between the DS3 MUX

and the low speed distribution modules (DLX, HLXC, ODS2, and RLX). The RTAU requires

no periodic maintenance. It requires the Version D1 or later DS3 MUX module and MPU

Version 5.3 or SCU Version 3.0 or later system software to be functional in the Soneplex

Broadband System for DS3 applications. If an earlier version of MPU software is used, the

RTAU will appear as a blank slot on the Craft Interface’s Inventory Status screen. Earlier

versions of the SCU software will not display the TAU slot.

The RTAU has the following features:

• Access supervision for intrusive testing (i.e., monitor access, split access for both A and

B transmission paths, and loop access for both A and B transmission paths).

• Stress testing of any circuit within the system via the Internal Test Signal Generation

feature. Many DS1 networks are tested by passing repeating sequences (patterns) of

logical ones and zeros through the network, also known as stress test patterns. As the test

patterns are applied to the circuit, they are compared with the original pattern to

determine if any errors are introduced. QRS (Quasi Random Signal) is one of the test

patterns supported. (QRS conforms to TR-NPL-000054.)

• Capable of inserting bit errors at a specified rate or as single errors or burst errors to the

DS1 circuit being tested.

• Ability to monitor (intrusively or non-intrusively) the DS1 circuit being tested.

• User control through the Craft Interface or via the TL1 interface.

• Access to the DS1 through front panel bantam jacks or through the internal test signal

generator. This control is configurable through the Craft Interface.

• Supports the Building Integrated Timing Supply (BITS) primary interface through the

wire wrap pins on the back of the Soneplex Broadband chassis. If a valid BITS signal is

applied to the Broadband chassis, the RTAU will automatically switch over to the BITS

primary interface and use the recovered clock for timing.

Note: The BITS secondary interface on the Soneplex Broadband chassis is not supported

by the RTAU.

2 INSTALLATION

There are two installation procedures:

• Initial Installation - This installation procedure applies to the first time an IBBC shelf

will be populated with a RTAU module.

• Maintenance Installation (Existing System) - This installation procedure applies to an

IBBC shelf that has already been populated with a RTAU module.

Please follow the appropriate procedure per your system configuration.

ADCP-61-743 •Issue 3 •September 2004

2.1 Initial Installation

This installation procedure applies to the first time an IBBC shelf will be populated with

a RTAU module. If the IBBC shelf has already been populated with a RTAU module, go

to 2.2. Maintenance Installation (Existing System).

Installation consists of unpacking and installing the RTAU module, and verifying that it is

functioning properly. Use the following procedure to install a RTAU module:

Caution: Electronic modules can be damaged by static electrical discharge. Before handling

modules, wear an anti-static discharge wrist strap to prevent damage to electronic

components. Place modules in anti-static packing material when transporting or storing. When

working on modules, always place them on an approved anti-static mat that is electrically

grounded.

Warning: If the RTAU module is improperly installed, damage can be caused to the system.

Be careful when inserting the RTAU module into a new chassis.

Caution must be used to prevent bending pins when inserting modules into a new IBBC shelf.

Once a module has been successfully seated in the connector, it “trains” the pins and aligns

them to the modules connector greatly reducing the chances of bending pins on subsequent

insertions. The following procedure outlines a method to mitigate the risk on a new shelf

installation.

1. Open the front cover of the Soneplex Broadband system.

2. Open the shipping carton and carefully unpack the RTAU module from its protective

packing material.

3. Once the Soneplex shelf has been installed and powered up:

a. Remove both-48V A and B side fuses (and “pilot” fuses if used).

b. Inspect the RTAU slots for bent or misaligned pins.

c. If pins are not bent, continue to the next step. If pins are bent, refer to 2.1.1 Damaged

Pins section.

4. With shelf unpowered, refer to the chassis marking above the module slot (Figure 2) to

install the RTAU module in the full-height slot labeled TAU.

5. Align the module edges of the RTAU with the mounting slot module guides. Use the

injectors to seat the module in the chassis.

6. Remove the RTAU module.

7. Inspect the backplane connector for bent pins.

8. If pins are not bent, continue to the next step. If pins are bent, refer to 2.1.1 Damaged

Pins section.

9. Re-install the RTAU module.

10. With the RTAU module installed, power up the shelf one fuse at a time.

a. Install the -48V A fuse.

b. Install the -48V B fuse.

Refer to 8. Customer Information and Assistance, if needed.

2.1.1 Damaged Pins

The pins used in the back plane connector should not be straightened after they have been

deflected more than 10 degrees from vertical as they will “work harden” and break at the

bend. Bent pins must be removed and replaced using special tools and is not

recommended as a field repair. Remove shelf with damaged pins and contact ADC for

replacement. Refer to 8. Customer Information and Assistance.

2.2 Maintenance Installation (Existing System)

Replacement of the RTAU module in existing IBBC shelves should follow normal

maintenance procedures. Since a module has already been in service in the affected slot, the

backplane pins will have been trained into alignment with subsequent replacement modules. If

excessive resistance is encountered upon insertion, remove the module and inspect for

misalignment or obstructions.

This procedure assumes that the IBBC shelf has already been populated with a RTAU

module. If this is the first time that the IBBC shelf has been populated with a RTAU

module, go to 2.1 Initial Installation.

Installation consists of unpacking and installing the RTAU module, and verifying that it is

functioning properly. Use this procedure to install a RTAU module.

Warning: To prevent electrical shock, never install equipment in a wet location or during a

lightning storm. When installing or modifying telephone lines, disconnect lines at the network

interface before working with uninsulated lines or terminals.

Caution: Electronic modules can be damaged by electrostatic discharge (ESD). Before

handling modules, wear an anti-static discharge wrist strap to prevent damage to electronic

components. Place modules in anti-static packing material when transporting or storing. When

working on modules, always place them on an approved anti-static mat that is electrically

grounded.

1. Open the front cover of the Soneplex Broadband (V5) chassis.

2. Open the shipping carton and carefully unpack the RTAU module from its protective

packing material. Inspect the module for damage

3. Refer to chassis markings above the module slot (Figure 2) to install the RTAU module

in the full-height slot marked TAU.

4. Align the module edges of the RTAU with the mounting slot module guides. Use the

injectors to seat the module in the chassis. If there is excessive resistance, remove the

module and check for obstructions or improper alignment.

3 LED CHECK

1. When the RTAU module (Figure 3) is seated, the STATUS LED will be lit red for

approximately 5 seconds. All LEDs will then flash yellow, and then the STATUS LED

will be lit green. If the STATUS LED is not lit green after 10 seconds, replace the

module. Refer to 2.2 Maintenance Installation (Existing System).
