Admonishments

Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.

Danger: Danger is used to indicate the presence of a hazard that will cause severe personal

injury, death, or substantial property damage if the hazard is not avoided.

Warning: Warning is used to indicate the presence of a hazard that can cause severe personal

injury, death, or substantial property damage if the hazard is not avoided.

Caution: Caution is used to indicate the presence of a hazard that will or can cause minor

personal injury or property damage if the hazard is not avoided.

General Safety Precautions

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 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.

2.1 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:

ADCP-61-743 • Issue 3 • September 2004

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.

Page 8

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.

SIGNAL GENERATOR SETUP FIELDS, CONTINUED

Pattern Type, continued Toggle 2^15-1 215-1 is a 32,767-bit, pseudo-random pattern

that generates a maximum of 14 sequential 0’s and 15 sequential 1’s. The pattern provides a maximum number of 0’s allowed for framed, non-B8ZS testing. The pattern does not meet the minimum 1’s density requirement.

2^23-1 223-1 is a 8,388,607-bit, pseudo-random

pattern that generates a maximum of 22 sequential 0’s and 23 sequential 1’s. The pattern exceeds excess 0’s and does not meet the minimum 1’s density requirements for T1 applications.

All Ones Test of T1 span line. The all-1’s pattern causes

the span line repeater to consume the maximum amount of power. If the current powering the span line is low, transmission errors may occur due to the inter-symbol interference resulting from the inability of a weak repeater power supply to develop the energy necessary to support the transmission of a long sequence of 1’s.

(Framed) All Zeros Used as a final confirmation that all network

elements in a circuit are properly optioned with B8ZS for clear channel operation. The framed all 0’s pattern consisting of a frame bit followed by an all 0’s payload will only be applied to circuit optioned with B8ZS for clear channel operation.

The pattern stresses a circuit by introducing rapid transitions from long sequences of low density octets to high density octets, high density octets to low density octets, and rapid transitions. The pattern may be transmitted framed or unframed. When framed, the frame bit shall be inserted at the octet boundaries and will not overwrite the bits.

SPLT option before the Loop Code field can be configured. Loop codes will be transmitted until the RTAU detects a change in the signal being received. At that time, the pattern selected before the loop code was set will be transmitted. For example, when sending a Loop Up code, the RTAU will restore the original pattern after it receives the loop code it is transmitting, indicating that the circuit is looped up. Note that the Loop Code bits are displayed in the Loop Code bit field as each code is selected. This is provided as a convenience to the operator who may not know the name chosen for the loop code but does know the pattern.
