Page 13: Introduction
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 Access 1500 DDS- Figure 1.

Page 17: Provisioning
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 ... -
Page 18: Provisioning And Status Ds6
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 ... -

Provisioning Options Select the appropriate Option and Rate using circuit board switches SW1 and SW4 as illustrated in Figure 2. Select options prior to board insertion. Figure 2. Option and Rate Selection Switches 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. Table 6.

Page 20: A/B Signaling (A/B)
Total Access 1500 Total Reach DDS-DP Installation and Maintenance Guide 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. -
Page 21: Testing
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. 61180105L1-5C... -
Page 22: Figure 3. Dds Trouble Codes
Total Access 1500 Total Reach DDS-DP Installation and Maintenance Guide 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 Customer Premises Channel Bank Open 2-wire Loop Alternating MOS (9Ah)/ ASC (9Eh) DDS-DP OCU-R Customer Premises Channel Bank... -

Page 37: Deployment Guidelines
Deployment Guidelines Deployment Guidelines 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).
