Note: The above provisioning options are based on 7
th
Generation HTU-R, 1247024L1 or 1247026L1.
Option settings for previous HTU-Rs, 1246026L4 and/or 1246026L6, that are either not supported
by the HTU-R, or are hardware options and cannot be provisioned from the HTU-C menu, will
display a asterisk (*), and options that follow will be renumbered sequentially.
FRONT PANEL BANTAM JACK TEST ACCESS
The BERT tester should be in Monitor mode for nonintrusive tests and Terminate mode for intrusive tests. Use the
Provisioning screen to configure the HTU-C for DSX or MUX-fed network source. Use the Test screen to configure
EQ jacks for Customer or Network direction. (The Network direction is only available when the HTU-C is MUX-
fed.) The BERT TX is only used in intrusive tests. Refer to the Total Access 3000/3010 HTU-C Installation and
Maintenance Practice (P/N 61181107L1-5) for more detailed information.
Nonintrusive DSX to Customer
Connect HTU-C TX MON to BERT RX
Allows access to DSX signal going to Customer
Nonintrusive DSX from Customer
Connect HTU-C RX MON to BERT RX
Allows access to DSX signal coming from the Customer
Intrusive DSX to Customer
Connect HTU-C TX EX to BERT TX and HTU-C RX EQ to BERT RX
Allows access to signal going to Customer
Nonintrusive MUX to Customer
Connect HTU-C TX MON to BERT RX
Allows access to signal going to Customer
Intrusive MUX to Network
From the Test screen (Option 5 from the HDSL Main Menu), verify Equipment Jack = Network
Connect HTU-C TX to BERT TX and HTU-C RX EQ to BERYT RX
Allows direct access to signal going to and from the Network
Intrusive MUX to Customer
Verify Equipment Jack = To Customer
HTU-C TX EQ to BERT TX and HTU-C RX EQ to BERT RX
Allows direct access to signal going to and from the Customer

TROUBLESHOOTING
Use the Status Screen to view the current condition of the HTU-C and signal.
The following are indications that a problem can exist with HTU-C or signal quality:
Is LOSS (pulse attenuation) >30 dB?
Are there any errors counting on the ES, SES or UAS registers?
Is the signal quality fluctuating (graphical meter indicators bouncing up and down)? This would occur when real
time mode is active.
If the signal quality is not fluctuating, is it unequal between the loops?
Is the current signal quality indication (uppermost “X” on the meter) more than 1 dB below the maximum?
If these conditions are not present, the circuit should provide quality service. If any of these conditions exist, a cable
problem or excessive signal loss is probable, and more testing should be done. These conditions can also reflect
intermittent cable faults or excessive noise impairments. If intermittent faults or noise impairment are suspected,
select the Performance Monitoring option from the HDSL Main Menu and review the historical performance data
on the Performance Monitoring Screen.
Circuit Parameters
Under normal operations, the following conditions apply:
LOSS < 30 dB
Signal margin of 3 dB or higher, no fluctuation and equal on both loops
All HDSL Deployment Guidelines are met
