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.

ADCP-61-743 Issue 3 September 2004  
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.

SPLTFL indicates a split in both the A and B paths  
and connects an SPD to the line incoming from the  
F direction and a TSG to the line outgoing in the F  
direction similar to SPLTF mode. The signal in the  
E direction is looped back.  
The LOOPE mode is a full split of both A and B  
transmissions paths. The incoming line in the E  
direction is connected to the SPD and this line is  
connected to the outgoing line in the E direction.  
The circuit will be looped in one direction. The  
outgoing line in the F direction (non-test direction)  
will be connected to a QRSS source and the line  
incoming from the F direction is terminated by the  
nominal characteristic impedance of the line.  
LOOPF  
The LOOPF mode is a full split of both A and B  
transmissions paths. The incoming line in the F  
direction is connected to the SPD and this line is  
connected to the outgoing line in the F direction. The  
circuit will be looped in one direction. The outgoing  
line in the E direction (non-test direction) will be  
connected to a QRSS source and the line incoming  
from the E direction is terminated by the nominal

OVERVIEW: If the desired pattern type is not  
available, select the User Code option to enter a  
pattern 32 bits or less.  
QRS  
20  
QRS  
Quasi-Random Signal. QRS (2 -1) is a 1,048,575-  
bit sequence generated by a 20-stage shift register  
with feedback taken from the 17th and 20th stages.  
The non-inverted output is taken from the 20th  
stage, and an output bit is forced to be a ‘1’  
whenever the next 14 bits are all 0’s. QRS is  
typically used to verify continuity and to check  
circuit performance in the presence of traffic-like  
signals. Quasi-random Signal (QRS) is a signal  
repeated every 1 to 24 bits as specified by the  
Operation System (OS) application. QRS must  
conform to the description in Bellcore TR-NPL-  
000054.

-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
-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.  
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.

Daly  
Daly Pattern (Modified 55 Octet). This is useful  
for stressing the timing recovery circuits of line  
cards and the preamplifier/ equalizer circuits of  
repeaters. 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.  
User Code  
For user-defined patterns of 32 bits or less, set the

OVERVIEW: The Mode field must be set to a  
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.
