Introduction
Introduction
This practice provides installation and maintenance procedures for the ADTRAN Total Access
1500 Total Reach DDS‐DP (TR DDS‐DP). The figure on the left, illustrates the front panel of the
TR DDS‐DP (P/N 61180105L1).
Description
The TR DDS‐DP delivers data at rates up to 64 kbps using a single copper pair. Used in combi‐
nation with the Total Reach DDS‐R termination unit, the Total Reach DDS‐DP can accom‐
modate extended loop lengths, eliminating the need for DDS repeaters.
• The TR DDS‐DP span powers the remote DDS‐R located at the customer premises.
• The DDS‐R converts the 2‐wire signal to the traditional 4‐wire Alternate Mark Inversion
(AMI) signal for presentation to the customer.
The TR DDS‐DP occupies a single channel position in the Total Access 1500 chassis. It
provides the interface between a DS0 time slot of the T‐carrier data stream and the 2‐wire
metallic loop extending to the customer premises. The TR DDS‐DP will interoperate over the
carrier system with another TR DDS‐DP, OCU DP, DS0 DP, 1/0 DCS, or switch and can be
located in an end office, hub office, intermediate office, or Digital Loop Carrier (see Figure 1).
The 2‐wire loop is connected using the Tip (pin 15) and the Ring (pin 35) on the Total Access
1500 backplane.

• Total Reach DDS‐DP
• Total Access 1500 Total Reach DDS‐DP Job Aid (P/N 61180105L1‐22)
Instructions for Installing the Module
The TR DDS‐DP plugs directly into a Total Access 1500 shelf. No special wiring is required.
The 2‐wire loop uses the T/R (Tip and Ring) pair, pins 15 and 35, of the Total Access 1500
backplane.
Remote Unit Span Power
The TR DDS‐DP span powers the remote unit by providing ‐130 VDC measured from Tip to
Ring. Voltage measured from Tip to GND should be ‐130 VDC or less depending on voltmeter
impedance. Voltage from Ring to GND should indicate approximately 0 V.
Front Panel LEDs
The TR DDS‐DP provides front panel LEDs to display status information. The TR DDS‐DP
LEDs and status descriptions are shown in Table 4.

Synchronization
The TR DDS‐DP and DDS‐R typically require 30 to 90 seconds to synchronize. Once synchro‐
nized, the Status LED will turn ON green. If synchronization cannot be achieved, check the T/
R pair for open‐circuit or short‐circuit conditions or load coils.
Connections
All connections are made through the 50‐pin Amphenol connector on the backplane of the
Total Access 1500. See Table 5.

Provisioning
Provisioning
On initial installation, the TR DDS‐DP is provisioned according to the factory default settings.
False Loopback Immunity
ADTRAN’s Protected Loopback family of channel units includes an algorithm compatible
with SARTS, Hekimian, TPI, and other test systems that virtually eliminate false latching
loopbacks. Immunity is automatically enabled at 64 kbps.
In addition, ADTRAN’s Protected Loopback family features a protected loopback mode for
further false latching loopback protection.
Latching Loopback
Latching loopbacks are always enabled except when temporarily disabled via the protect
loopback features. When 64 kbps is enabled, placing SW1-3 (PLB) to OFF will permit the TR
DDS‐DP to respond to the legacy latching loopback sequence as described in TR62310 and
ANSI T1.107. At 64 kbps, placing SW1-3 to ON, the TR DDS‐DP will enable ADTRAN’s
Protected Loopback mode.
Control Protocol
Remote access to provisioning and status information is accomplished using either ADTRAN
Digital System 6 Message protocol defined in Control and Diagnostic Procedures Practice,
Section 6032991‐6, or through the craft interface on the Total Access 1500 SCU. Digital System
6 is supported by the TPI 108/109 and 105 portable test sets and is supported by Hekimian
React 2001 Revision 1900 remote test system.
The TR DDS‐DP network elements comply with ANSI T1.107‐1995, “Digital Hierarchy Format
Specifications Annex G” which allows remote provisioning, querying, and performance
monitoring via in‐band control of network elements.
NOTE
The REACT 2001 GUI software Release 1.900 supports ANSI T1.107‐1995.
Remote access is accomplished using a defined set of in‐band DS0 byte sequences similar to
the latching loopback sequence. Commands issued via the test system are recognized by the
individual channel unit which responds with the appropriate byte sequences. These in‐band
commands can be used to verify options via dialogs with REACT 2001, TPI 108/109 and TPI
105 test sets. Unit CLEI, serial number, provisioning, and performance information can be
retrieved remotely using the Digital System 6 protocol.
61180105L1-5C

Total Access 1500 Total Reach DDS-DP Installation and Maintenance Guide
Provisioning and Status DS6
All configuration options can be remotely viewed or provisioned via DS6. The front panel
remote (REM) LED indicator flashes during DS6 control link establishment and remains ON
after the channel unit has been remotely provisioned. The newest provisioning will overwrite
any existing provisioning contained on the TR DDS‐DP.
Time Slot Assignment
The Total Access 1500 platform can have multiple time slots in the T1 data stream assigned to
each physical slot in the channel bank. The Total Access 1500 allows craft selectable time slots
using the electronic provisioning interface.
AP-Switch
If the channel unit has been remotely provisioned, the operator can alternate between remote
configuration and manual switch settings by pressing the momentary Alternate Provisioning
(AP) switch located on the front panel. If the channel unit is removed from the system, the
Total Access 1500 bank slot retains the last remote provisioning information. A similar TR
DDS‐DP placed in that slot will assume the same remote provisioning.
REM Indicator
The REM indicator remains ON when the channel unit is operating based on remote provi‐
sioning, and is OFF when operating on manual switches. If the channel unit has never been
remotely provisioned, the AP switch has no effect and the REM indicator remains OFF. See
Table 4 on page 5 for LED indication.
Out-of-Band Diagnostics
In addition to in‐band access to TR DDS‐DP performance diagnostics and provisioning via
Digital System 6, access is also available out‐of‐band (non‐intrusively) via the craft interface
located on the Total Reach DDS‐R.
The TR DDS‐DP displays provisioning information, Total Reach system status, performance
monitoring information stored in 15‐minute and 24‐hour registers for both the Total Reach
DDS‐DP and Total Reach DDS‐R, and an event log which time stamps system performance
anomalies and threshold violations.
Physical access to the terminal interface on the Total Reach DDS‐R is made by a serial interface
connection to a dumb terminal or dumb terminal emulation. Provisioning of the TR DDS‐DP
may be viewed but not changed from the terminal interface on the Total Reach DDS‐R.
Further information about the Total Reach terminal interface and performance monitoring
may be found in the Total Reach OCU‐R Frame IQ with Craft Interface All Rate DDS Termination

Protected Loopback (PLB)
ADTRAN’s Protected Loopback supports the new proposed DDS latching loopback standard
in T1E1.2/99‐007R1. When Protected Loopback is enabled, the TR DDS‐DP will respond to
latching loopback when the idle code preamble is sent prior to the latching loopback sequence
specified in TR62310 and ANSI T1.107.
Protected Loopback prevents false latching loopbacks when the loopback sequence is
embedded in customer payload data. Test equipment should support T1E1.2/99‐007R1 to
perform testing at 64 kbps when protected loopback is enabled.
See Table 6 for the latching loopback sequence requirement when Protected Loopback is
enabled.

NOTE
A minimum of 35 TIP bytes is required to disable established latching
loopback. X = Donʹt Care bit.
A/B Signaling (A/B)
When A/B Signaling (SW1-4) is OFF, the unit derives signaling from the incoming data stream.
When A/B Signaling is ON, the unit determines the state of the A and B Signaling bits using
signals present on the backplane of the channel bank. This method assumes that proper
signaling has been maintained throughout network tandems and cross connect systems.
NOTE
A/B Signaling option is only applicable when SW56 is selected; otherwise it is a
“don’t care.”
Quality Monitor (QM)
When Quality Monitor (SW1-5) is ON, the TR DDS‐DP monitors the incoming 2‐wireloop and
4‐wire customer interface data for errors. If excessive errors are detected, the unit blocks the
customer’s data transmission and transmits an alternating MOS (9Ah)/ASC (9Eh) trouble code
to the network. Customer data transmission is automatically restored when the trouble
condition is cleared.
Rate Selection
Select rate with dip switch (SW4) by positioning the selected switch toward the inscribed rate.
NOTE
Select only one rate. More than one, or none, defaults to 56 kbps without
secondary channel.
NOTE
If either SW56 or 64 kbps is selected, the secondary channel (SC) switch
should not be selected.

61180105L1-5C
Testing
Testing
The TR DDS‐DP is equipped with logic level bantam test access jacks that permit testing in
both directions using a portable test set. Latching DS0 and CSU loopback sequences and alter‐
nating CSU loopback sequences are supported.
Alternating loopbacks do not operate when the 64 kbps data rate is selected. Choose NEAR to
test toward the customer loop; choose FAR to test toward the T‐carrier. In the FAR direction, a
DS0 loopback sequence will loop the unit directly across the T‐carrier system. In the NEAR
direction, a DS0 loopback sequence will loop the unit directly connected to the portable test
set.
NOTE
If 64 kbps is selected, the unit will only respond to latching loopback
sequences. Alternating sequences are not valid at this rate.

TR DDS-DP Trouble Code
The TR DDS‐DP system provides a quick diagnosis in the case of a circuit condition where
continuity is broken. The trouble code type received by a tester determines whether the open
condition is occurring on the local loop or at the customer premises. In the event of a 2‐wire
DSL loss of signal, loss of sync, or an open condition caused by an open conductor or discon‐
nected 2‐wire loop, the TR DDS‐DP transmits an alternating MOS (9Ah)/ASC (9Eh) trouble
code into the network as shown in Figure 3. During a similar Out‐of‐Service condition at the
customer premises, the Total Reach OCU‐R transmits an ASC (9Eh) upstream into the
network

TR DDS-DP Bidirectional Loopback Support
The TR DDS‐DP will execute a bidirectional loopback when performing a DS0 loopback at the
TR DDS‐DP as shown in Figure 4. During a bidirectional loopback the DDS‐R enables test
data to pass through the 4‐wire interface to the customer site. This allows a standard portable
test set at the customer site to verify the integrity of both the 4‐wire and 2‐wire loops by trans‐
mitting a test pattern to the TR DDS‐DP and examining the returning data for synchronization
and errors.
A bidirectional loopback and pass‐through is shown in Figure 5. During a bidirectional
loopback initiated at the TR DDS‐DP the DDS‐R CUST LBK LED will flash.

on the Total Access 1500 SCU. The following section provides detailed provisioning and
diagnostic information.
• Control Protocol
• Provisioning and Status DS6
• Electronic Provisisioning
Control Protocol
Remote access to provisioning and status information is accomplished using either ADTRAN
Digital System 6 Message protocol defined in Control and Diagnostic Procedures Practice, Section
6032991‐6, or through the craft interface on the Total Access 1500 SCU. Digital System 6 is
supported by the TPI 108/109 and 105 portable test sets and is supported by Hekimian React
2001 Revision 1900 remote test system. The Total Reach DDS network elements comply with
ANSI T1.107‐1995, “Digital Hierarchy Format Specifications Annex G” which allows remote
provisioning, querying, and performance monitoring via in‐band control of network
elements.
NOTE
The REACT 2001 GUI software Release 1.900 supports ANSI T1.107‐1995.
Remote access is accomplished using a defined set of in‐band DS0 byte sequences similar to
the latching loopback sequence. Commands issued via the test system are recognized by the

The Total Reach DDS‐DP and DDS‐R use technology intended to eliminate the need for
repeaters and concerns over impairments caused by typical noise and bridged tap. Table 8
describes cable loss for the Total Reach DDS Nyquist frequency of 13.3 kHz, while Table 9
measures the DDS insertion loss. Listed below are the loop design guidelines for Total Reach
DDS:
• All loops must be nonloaded.
• Actual measured loss (AML) should not exceed 50 dB at 13.3 kHz (135 Ω termination), the
Nyquist frequency of Total Reach DDS.
NOTE
The 50 dB AML limit includes 6 dB of signal margin to account for potential
near‐end cross talk (NEXT) from other digital services that may be
provisioned in the same binder group.
• Loop length should not exceed 50 kft.
• Bridged tap length should not exceed 12 kft.
• Background noise level should not exceed 34 dBrn.
• Impulse noise level should not exceed ‐40 dBm, (+50 dBrn).
