Acterna HST-3000 Handheld Consumer Services Tester

Improving the installation, maintenance and troubleshooting of DSL services
operators are rapidly deploying DSL in their networks to deliver multimedia services over the existing copper wire in the local loop. Traditionally, one set of technicians performed individualized tests that qualified the copper while another set conducted DSL services testing and verification. In today’s market, however, operators can no longer afford the time, capital expense, and labor costs to conduct tests separately and incrementally. Furthermore, test solutions must generate results that have a strategic impact throughout an operator’s entire organization. This may include building customer loyalty by locating and fixing problems quickly, improving profitability by performing more tests with less staff, or leveraging workforce productivity by automating processes, methods, and procedures.

handheld tester that can be built to order, to test the copper, test the DSL service and improve the process. Technicians use the HST-3000 copper base instrumentand the copper service interface module (SIM) to qualify, maintain, and troubleshoot the local loop. This same base instrument, with a second SIM that tests both ADSL and the copper, enables one technician to perform tests thatwere previously conducted by two technicians using different equipment.

For those technicians who only need to test ADSL, the instrument can be configured for ADSL functionality only. Any HST-3000 module equipped to perform ADSL service tests can also verify ISP and Internet connectivity with the Acterna Advanced IP Suite software option. With the HST-3000 minimize the time and reduce the capital expense and labor cost associated with ADSL and copper testing.

The JDSU HST-3000 is the ideal instrument for testing T1 services with built-in functionality that reduces repeat rates, failures, and kickbacks and ensures that all tests are performed the same way, every time.

Reduced budgets, smaller workforces, and untrained technicians can limit a carrier’s ability to promptly provision T1 service. Overcoming these obstacles requires resources that facilitate the efficient and rapid deployment of T1 services regardless of whether the T1 line uses traditional repeaters, HDSL, HDSL2, or HDSL2 4-wire circuits.

Technicians use the HST-3000 optional copper test features to qualify and troubleshoot the circuit, and the T1 test features to bit-error-rate test (BERT) the line and verify the service. With the VT100 emulation feature, the HST-3000 provides instant access to HDSL/2/4 performance statistics. There is no need for technicians to switch instruments or modules; the HST-3000 combines all the tests into one tool with one common interface. The HST-3000 custom scripting feature automates the testing process, ensuring that tests are done completely and thoroughly every time and helps reduce repeat rates and failures by ensuring that the processes used to test are consistent. With the HST-3000, technicians can complete faster service turn-ups, reduce failure rates, and lower costs, which are all key components to surviving in today’s competitive environment.

Loopback Testing

Preprogrammed HTU-C, HTU-R, doubler, T1 CSU, T1 NIU, and repeater loopcodes enable the HST-3000 to quickly sectionalize transmission problems. In addition, Pairgain, Teltrend, Adtran, Westell, and ADC equipment specific loopcodes, as well as user configurable loopcodes, are supported. The test set can also emulate T1 customer premises equipment, simulating a CSU or NIU. CSU/NIU emulation allows the test set to be looped up from the central office to verify T1 service across the entire length of the span.

Dual T1 Transmit and Receive

The HST-3000 dual T1 transmit and receive capabilities give the ability to measure timing slips, passively monitor T1 circuits in both directions, and perform drop and insert testing. Using the split screen view in dual monitor mode, a span is easily sectionalized to quickly determine the location of a fault. Drop and insert testing allows the user to BERT single DS0s within a T1, without taking the entire T1 out of service.


Through the test instrument’s VT100 emulation feature, technicians can access HDSL and T1 network equipment for equipment configuration, specific performance data measurements, and loop up capabilities, without having to carry a laptop into the field. With JDSU’s repeater extender, technicians can also gain access to the circuit at T1 repeaters.

Fractional T1

The HST-3000 performs fractional T1 (FT1) BER tests on selected channels to verify transmission on contiguous and noncontiguous FT1 bandwidth. This allows the technician to verify circuit performance with VF and 577 Hz ID tones at various output levels. In addition, the HST-3000 uses a variety of advanced stress patterns such as 55 octet, T1-DALY, and other long user patterns as recommended by the ANSI T1.403 standard to stress repeatered T1/FT1 circuits. With its enhanced T1 features and functions, the HST-3000 is the ideal test instrument for technicians to troubleshoot and qualify the line swiftly and effortlessly.

Flexible and Rugged Design

The HST-3000 incorporates a rugged, weather-resistant design and long battery life that are ideally suited for use in the field and its modularity allows for field upgrades to support new testing requirements. The HST-3000 is easily upgradeable with technologies and advanced options that support the changing needs of service installers and its dynamic configurability allows it to be used by different technicians with different responsibilities to perform a wide number of tests. Standard Ethernet, USB, and serial connections offer flexibility to easily download software and offload captured test data.


Beginning with the construction of the circuit, and throughout the life cycle of the service, operators must verify that customers are receiving the quality they ordered. Whether qualifying the copper before handing the circuit over to an installation and maintenance crew, a technician must run a bit-error-rate test (BERT) to prequalify the circuit to ensure that it will run T1 service error free.


To verify proper T1 transmission over a traditional repeatered T1 or an HDSL circuit, a technician needs to test the entire span from the central office to the customer premises. A true end-to-end service test requires stressing the span and verifying the error tolerance of the copper plant and network equipment. The HST-3000 includes the advanced stress patterns of the T-BERD to properly stress the network.


The HST’s copper testing features allow quick turn-up and troubleshooting of the services provided over copper. This includes testing with DVOM, opens, power (Mains) influence (PI), noise, balance, time domain reflectometer (TDR), resistive fault locate (RFL), load coil detect, loss, wideband transmission impairment measurement set (WBTIMS), caller ID, and POTS dialer.

The HST provides process customization through on-board auto tests and allows workflow improvements via connectivity to craft access terminals and back-office systems.

The copper testing features include the following:

  • Measuring AC and DC voltage, current, and resistance
  • Measuring to opens (length of cable)
  • Measuring balance, noise, and power (Mains) influence (PI)
  • Locating cable faults with the TDR or RFL
  • Detecting load coils
  • Measuring loop loss (voiceband) including receiving and sending tones; transmission impairment testing (noise, SNR, return loss)
  • Voice service and caller ID (CLID) testing
  • WBTIMS and WB2 TIMS testing including sending/ receiving tones; measuring wideband, impulse, and spectral noise; and transmission impairment testing (noise, SNR, return loss, crosstalk)
  • Automatic testing using scripts, including POTS close out, good pair check, and wideband auto tests.

ADSL is designed to carry a digital signal, over a copper pair, above the voice frequency band (20 KHz–1.1 MHz) to enable high speed internet service over a standard POTS line. This allows “always on” internet access while simultaneously providing voice service. Typical POTS line quality will normally support ADSL, but the DSL service must be tested when trouble strikes. To troubleshoot DSL service, a modem emulation test set, such as the HST-3000, is needed. The DSLAM and network configuration is verified by connecting at the main distribution frame (MDF) where known interference and attenuation are minimal, as shown in Figure 1. The physical (ADSL) layer data rates and noise margins are reviewed to confirm that they match the service contract. Validate correct DSLAM and BRAS provisioning by connecting to the customer line and authenticating with the network through the DSLAM.
