Acterna HST-3000 Handheld Consumer Services Tester
Improving the installation, maintenance and troubleshooting of DSL services
With a market primed for broadband, 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.
The Acterna HST-3000 is a modular 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 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.

IPv6 features an auto-configuration facility, defined in RFC2461, which greatly simplifies address configuration. In “stateless” mode, an IPv6 host will automatically configure itself with a unique link-local address, which enables it to communicate locally on its own subnet. For communication over the Internet, the local router provides the host with a global address. Both transactions are completely transparent to the user, resulting in a truly plug-and-play environment. IPv6 also supports manual address configuration and DHCPv6 using a “stateful” address configuration when network administrators require tighter control over IP address allocation. The IPv6 option on the HST-3000 Ethernet SIM supports all three configuration schemes for IPv6 traffic testing for 10/100/GigE networks.
The IPv6 option also features Monitor/Thru mode testing in which the HST-3000 gathers and analyzes live IPv4 and IPv6 traffic.
