HDSL2 SYSTEM TESTINGThe Total Access 3000 H2TU-R provides diagnostic, loopback, and signal monitoring capabilities.

The front panel LEDs provide diagnostics for HDSL2 loops, DS1 signals, alarms, provisioning and loopbacks. Refer to “Front Panel Pushbuttons” on page 7 for details.

The Total Access 3000/3010 H2TU-R provides local and remote loopback capabilities via the loopback buttons on the front panel. Refer to “Front Panel Pushbuttons” on page 7 for details.

Total Access 3000/3010 H2TU-R Network LoopbacksThe Total Access 3000/3010 H2TU-R responds to multiple loopback activation processes. The loopback position is a logic loopback located within the Total Access 3000/3010 H2TU-R internal HDSL transceiver.

First, manual loopback activation may be accomplished using the control port of the Total Access 3000 SCU.

Second, the Total Access 3000/3010 H2TU-R will respond to HDSL2 loopback codes as defined in ANSI document T1.418-2002. A synopsis of the method described by ANSI is presented in “Appendix A, HDSL2 Loopbacks”.

Third, the Total Access 3000/3010 H2TU-R will respond to manual loopback activation by pressing the LOC LBK button on the front panel. This will activate a bidirectional loopback at the Total Access 3000/3010 H2TU-R.

Finally, the Total Access 3000/3010 H2TU-R responds to T1 Network Interface Unit (NIU) loopback codes as described in Bellcore TR-TSY-000312 if the Total Access 3000/3010 H2TU-R is optioned for NIU loopbacks. The NIU loopback codes are listed in Table 5.

The Total Access 3000/3010 H2TU-R will respond to the loop up codes by activating the NIU loopback from either the disarmed or armed state. The loop down codes will return the Total Access 3000/3010 H2TU-R to the normal state from the armed or loop up state.

Refer to “Appendix A, HDSL2 Loopbacks” for more details on loopbacks and loopback arming sequences.

Bantam JacksThe front panel of the Total Access 3000/3010 H2TU-R contains both metallic splitting (EQ) jacks and bridging (BRG) bantam jacks. The EQ bantam jacks on the Total Access 3000/3010 H2TU-R front panel provide intrusive access to the signal being transmitted and received from the H2TU-C. The BRG bantam jacks are used in conjunction with a BERT for nonintrusive and intrusive test access.

The EQ jacks provide an intrusive access point, interrupting signal access to the local loop. This will enable the user to transmit a test signal toward the H2TU-C and receive a test signal from the H2TU-C.

The BRG jacks, when connected to a bit-error rate test set that is configured for bridging mode, provide a nonintrusive test access point for observing the transmit or receive signal. In this configuration, synchronization, test patterns, and other functions can be observed.

Alternately, the BRG jacks can also be used for intrusive testing toward the customer. In this configuration, the Total Access 3000/3010 H2TU-R DS1 interface must be disconnected by opening both the metallic splitting TX and RX EQ jacks with either a bantam open plug or a bantam test cord that is not terminated. Then, a test set, configured for terminate mode, can be connected to the BRG jacks, and test access toward the customer equipment is achieved. Connect the output (TRANS) of the test set to the BRG TX jack.

Figure 3 illustrates the complete bantam jack arrangement and details for specific jacks.

HDSL2 Deployment Guidelines

HDSL2 DEPLOYMENT GUIDELINESThe ADTRAN HDSL2 system is designed to provide DS1-based services over loops designed to comply with Carrier Service Area (CSA) guidelines. The guidelines given below are only applicable to the first segment of the circuit (between the H2TU-C and H2R) or an HDSL2 circuit with no H2R.

• All loops are nonloaded only.

• For loops with 26-AWG cable, the maximum loop length including bridged tap lengths is 9 kft.

• For loops with 24-AWG cable, the maximum loop length including bridged tap lengths is 12 kft.

• Any single bridged tap is limited to 2 kft.

• Total bridged tap length is limited to 2.5 kft.

• The total length of multigauge cable containing 26-AWG cable must not exceed

– 12 – {(3*L26)/(9-LBTAP)} (in kft)

where:

- L26 = Total length of 26-AWG cable excluding bridged taps (in kft)

- LBTAP = Total length of all bridged taps (in kft)

This deployment criteria is summarized in the chart shown in Figure 18.

TROUBLESHOOTING PROCEDURESUse Table 17 to troubleshoot the Total Access 3000/3010 H2TU-R.

Table 17. Troubleshooting Guide

Condition Solution

All front panel indicators are off.

1. Make sure the Total Access 3000/3010 H2TU-R is properly seated in the shelf.

2. Verify that the H2TU-C is delivering sufficient simplex voltage to the loop.

3. If steps 1 and 2 pass, and indicators are still off, replace the Total Access 3000/3010 H2TU-R.

Power is present and adequate, but loop sync is not available (DSL LED is off).

1. Verify that the first segment of the loop conforms with CSA guidelines (not too long, etc.).

2. Verify that loop loss at 196 kHz is not greater than 35 dB on the first segment and 31.25 dB on the second segment.

3. Verify that noise on the HDSL2 loop is within acceptable limits (refer to “HDSL2 Deployment Guidelines” on page 27).

4. If steps 1 through 3 pass and loop sync is still not available, replace the unit with one known to be in proper working condition.

Appendix AHDSL2 Loopbacks

HDSL2 MAINTENANCE MODESThis appendix describes operation of the HDSL2 system with regard to detection of in-band and ESF facility data link loopback codes. The operation of the loopback commands in the ADTRAN HDSL2 system is compliant with the recommendation to ANSI recorded in T1.418-2002. The HDSL2 network loopback points described below are shown in Figures A-1 and A-2.

H2TU-C Loopback: A regenerative loopback of the DSX-1 signal toward the network.

H2TU-R Loopback: A regenerative loopback of the DS1 signal toward the network. This loopback is in addition to a separate Smartjack loopback. Separate activation sequences are provided for the H2TU-R and the Smartjack loopback initiation.

Upon deactivation of a loopback, the HDSL2 system will synchronize automatically.

Figure A-1. HDSL2 Loopback Points

Loopback Process DescriptionIn general, the loopback process for the HDSL2 system elements is modeled on the corre-sponding DS1 system process. Specifically, the H2TU-C loopback is similar to an Intelligent Office Repeater loopback and the Total Access 3000/3010 H2TU-R loopbacks are similar to an inline T1 Repeater loopback.

Each HDSL2 system element is independently described by the state diagram shown in Figure A-2. The four states are disarmed, loop up, armed, and loop up/time out disable.

Figure A-2. HDSL2 Element State Diagram

State transitions result from in-band and ESF Data Link sequences as well as time out opera-tions. The sequences and time out values are as follows:

1. Arming Sequence (in-band and ESF)

2. Activation Sequence

3. Deactivation Sequence

4. Disarming Sequence (in-band and ESF)

5. Loop Up Time Out

6. Arming Time Out

In-Band control code sequences are transmitted over the DS1 link by either the unframed or overwrite method. The HDSL2 elements respond to either method.

The unframed method produces periodic control sequences and the normal DS1 framing bit is omitted.

The overwrite method produces periodic control sequences. However, once per frame, the framing bit overwrites one of the bits in the control sequence.

The unit can detect the loopback activation or deactivation code sequence only if an error rate of 1E-03 or better is present.

States and State TransitionsA summary of time out and control sequences is given in Figure A-1.

NOTEIn all control code sequences presented, the inband codes areshown left-most bit transmitted first, and the ESF data link codeswith right-most bit transmitted first.

The Disarmed State is the normal mode of operation. Each HDSL2 element is transparent to the data flow. However, the in-band data flow and the ESF data link are monitored for the arming sequence.

The in-band control code sequence used to simultaneously arm the loopback capability of all of the HDSL2 elements is the following 5-bit pattern:

Arm Sequence 11000Note that this sequence is the standard NIU loop up code. If the NIU loopback feature for the HDSL2 circuit is enabled (see H2TU-C Switch Options), the arming sequence will activate the NIU loopback in the Total Access 3000/3010 H2TU-R. If the NIU loopback feature is disabled and an external Smartjack NIU is present, the HDSL2 arming process will not interfere with NIU detection of the loop up code.

All other in-band sequences are ignored in the disarmed state.

The ESF Data Link sequence used to simultaneously arm the loopback capability of all of the HDSL2 elements is the following 16-bit pattern ESF data link sequence:

ESF Arm Sequence 0001 0010 1111 1111 for four repetitionsHDSL2 element arming and NIU loop up is performed as described for the in-band arming sequence.

All other ESF patterns are ignored in the disarmed state.

In the Armed State, the HDSL2 system element continues to be transparent to the data flow. However, the in-band data flow and ESF data link is monitored for disarming and activation codes. An arming time out value causes the automatic return of the HDSL2 element to the disarmed state.

Transition from Armed to Loop Up State:An in-band control code sequence is used to command a specific HDSL2 element to move from the armed state into the loop-up state. Each HDSL2 element has a unique 16-bit activation control code sequence as shown in the following example.

Appendix A, HDSL2 Loopbacks - HDSL2 MAINTENANCE MODES

The designated HDSL2 element will loop up after receiving the proper activation sequence.

If the NIU loopback feature for the HDSL2 circuit is enabled (see H2TU-C Switch Options), the 5-bit in-band arming sequence (11000) or the 16-bit ESF data link sequence (0001 0010 1111 1111) will activate the NIU loopback in the Total Access 3000/3010 H2TU-R.

Transition from Armed to Disarmed StateAll HDSL2 elements can be commanded to move from the armed state into the disarmed state by the standard 5-bit in-band disarming sequence used for NIU Smartjack loop down. Each HDSL2 element must disarm after receiving the following code for 5 seconds per element:

Disarm Sequence 11100The disarming process ensures race-free operation of HDSL2 element disarming and Smartjack loop down. Duration of the disarm sequence may need to exceed 24 seconds to allow detection and loop down of up to three HDSL2 elements and the Smartjack.

All HDSL2 elements can be commanded to move from the armed state into the disarmed state by the ESF DATA LINK disarming sequence used for NIU Smartjack loop down as follows:

ESF Disarm Sequence 0010 0100 1111 1111 for four repetitions per element in loopback

The disarming process ensures race-free operation of HDSL2 element disarming and Smartjack loop down. Duration of the disarm sequence may need to exceed 16 repetitions to allow detection and loop down of up to three HDSL2 elements and the Smartjack. This sequence will loop down the Smartjack and the HDSL2 element.

All HDSL2 elements will automatically move from the armed state into the disarmed state when a default time out value of 2 hours is reached.

Arming Time Out 2 Hours

Overriding Loopback Time OutIf the units are armed and this pattern is sent, the loopback time out will be disabled. The time out option will be updated on the Provisioning Menu of the HTU-R (viewable through the RS-232 port) to “None”. As long as the units remain armed, the time out will remain disabled. When the units are disarmed, the loopback time out will return to the value it had before the D5D6 code was sent.

Loopback Time Out Override 1101 0101 1101 0110

Disabling Span PowerIf the units are armed and this pattern is sent, the H2TU-C will deactivate its span power supply, turning off the Total Access 3000/3010 H2TU-R and HRE (if present). As long as the pattern continues to be sent, the span power supply will remain disabled. When the pattern is no longer being sent, the H2TU-C will reactivate its span power supply, turning the remote unit(s) on. All units will retrain and return to the disarmed and unlooped state.

Span Power Disable 0110 0111 0110 0111In the Loop up State, the selected HDSL2 element provides continuous loop up of the DS1 signal. However, the data flow is monitored for the in-band deactivation sequence, the in-band disarming sequence, and the ESF data link disarming sequence. Also, a loop up time out

61181126L2-5A A-5


value causes automatic return to the armed state. All other control code sequences are ignored in the loop up state.

Transition from Loop Up to Armed StateAny HDSL2 element can be commanded to move from the loop up state into the armed state by a single in-band 16-bit deactivate control code sequence. The same deactivation sequence as shown is used for all HDSL2 elements.

Deactivation Sequence 1001 0011 1001 0011An HDSL2 element must loop down after receiving this deactivation sequence for at least 5 seconds.

Deactivation After Receiving Sequence for > 5 secondsDuration of the deactivation sequence may need to exceed 18 seconds to allow detection and loop down of up to three HDSL2 elements. The deactivation sequence does not disarm the HDSL2 elements. They can still respond to activation sequence control codes.

All HDSL2 elements automatically move from the loop-up state into the armed state when the selected loop up time out value is reached.

Loop Up Time Out programmable from the H2TU-C at None, 20, 60, or 120 minutes

Transition from Loop up to Disarmed StateAll HDSL2 elements can be simultaneously commanded to move from the loop up state into the disarmed state by either the standard 5-bit in-band disarming sequence used for NIU Smartjack loop down, or by the ESF DATA LINK command, as described in Transition from Armed to Disarmed State.
