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.

JDSU HST-3000 SIM ADSL2-TX ANX A Module
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.
The HST-3000 ADSL testing features use modem emulation (ATU-R Annex A or Annex B) to turn up and troubleshoot ADSL and ADSL2 services as well as provide ATM statistics and analysis. The internet protocol (IP) suite software allows IP/PPP troubleshooting. The on-board web browser option validates an internet connection. The capabilities of the ADSL features include the following:
- Variety of ADSL testing modes for service verification, local loop testing, and network connectivity:
|ADSL Modem emulate mode
||Used to test basic ADSL physical layer rates, quality and line statistics.
Also used for testing the following types of lines: IP over Ethernet, IP over ATM, PPP over Ethernet, and PPP over ATM.
|ADSL Through mode
||Used for testing the following types of lines: Bridged Ethernet, IP over ATM, PPP over Ethernet, and PPP over ATM.
||Used to loopback ATM cells.
|Ethernet TE mode
||Used for testing IP over Ethernet and PPP over Ethernet.
