As a widely deployed service, ISDN is a key source of revenue for telecommunication service providers world-wide. This, coupled with today’s reduced budgets and smaller workforces, make it more critical than ever to ensure the timely and successful turn up and maintenance of ISDN service – the first time out. Additionally, thorough ISDN testing can prove more complex than basic physical layer and BER testing for technicians who lack the necessary training. To meet these challenges, an easy-to-use, versatile test solution is required that helps reduce failures and repeat rates while enhancing efficiency and ensuring consistent test practices.

The Acterna HST-3000 is a powerful and versatile test instrument for testing ISDN PRI service. Hand-held, rugged and easy-to-use, the HST-3000 is ideal for field use. Its modular design provides a scalable, all-in-one solution for ISDN testing, as well as thorough testing of the facilities over which it is provided.

The HST-3000 ISDN PRI option enables testing of Primary Rate ISDN circuits at both the customer site and central office. It supports call placement, receipt, D-Channel Decode analysis for 23B+D, NFAS (Non-Facility Associated Signaling), 24B and backup D channel switching. With the full range of T1 loopcodes and BERT patterns it can also test BER across any combination of channels to verify service before delivery to the customer.

Compact and rugged for field technicians, the HST-3000 can be used in all conditions, from an inside office environment to a noisy, wet outdoor span repeater. The HST-3000 also boasts automated setups and advanced features that ensure consistent adherence to service provider methods and procedures. Each HST-3000 is built to order and can easily be field-upgraded with new modules and software as application and technology needs change.

Call Verification
The HST-3000 can place, receive and monitor ISDN PRI calls on a primary or secondary T1 interface. It has the ability to place and receive single or NFASvoice, 3.1 kHz audio, 56k data, 64k data, Nx56/64k data or H0 calls. In addition, dual transmit/receive interfaces, standard on each T1 Service Interface Module (SIM), allows the HST-3000 to be deployed to test in-service to standby D-channel switching. Allmajor call controls are supported, including National, DMSand 5ESS.

For incoming calls, the HST-3000 can either prompt the user to accept or reject the call, automatically accept or reject the call, or accept and loop back the B channels. After a call has been accepted, the technician can drop the received B channel data to the speaker or headset or BERT the call. BER testing and a voice path via a handset is provided to qualify these data and voice calls, respectively. This allows technicians to access T1 physical linkmeasurements and verify switch translations prior to delivering service.

Easy-to-read result menus allow technicians to view ISDN statistics, call status, BERT results, T1 results and D-channel decodes. Technicians can also view a summary screen that presents a rapid assessment of test performance and a summary of results for the physical layer, LAPD and Q.931 results.

D-Channel Decodes Analysis
D-Channel decodes help to verify that a call is successfully established, or determine why a callwas not completed by examining the protocol cause values. The HST-3000 can monitor layer 2 (Q.921) and layer 3 (Q.931) cause code messages on the D-channel in both terminate and monitor modes. Layer 2 results give technicians the ability to check link and D-channel status, verify LAPD frames and check utilization rates. Following link establishment, layer 3 decodes allow technicians to verify such factors as call state, who made or dropped the call, why the callwas dropped, where the call is being carried (Interface ID/B-Channel) and call types.

Non-intrusive, bi-directional monitoring of in-service D-channel signaling messagesmakes troubleshooting ISDN service easier. For ISDN PRI circuits, the technician can access live D-channel lines through monitor jacks on a DSX patch panel. If the problem can not be isolated, then sectionalization can be accomplished byemulating either the TE or the NT. This enables the technician to sequentially replace each piece of premise equipment to identify the source of errors– reducing the total time to trouble resolution. Results can be displayed on-screen or stored for later retrieval and output via RS-232, USB or Ethernet connectivity standard with each base unit.

Flexible and Rugged Design
The HST’s rugged, weather resistant design and long battery life are ideally suited for use in the field. Itsmodularity allows for field upgrades to support new testing requirements. Standard Ethernet, USB and serial connections offer flexibility to easilydownload software and offload captured test data.

Easily configurable, the HST-3000 can be used by different technicianswith different responsibilities to perform a wide number of tests. The HST-3000 is easilyupgradeable with technologies and advanced options that support the changing needsof service installers.

HST-3000 SIM T1 Service Interface Module

  • VT100 emulation for access to T1,HDSL,HDSL2, HDSL2-4 wire performance statistics
  • Lower repeat rates with automated close out tests, scripting, and pass/fail tests loaded with operator specific thresholds for methods and procedures
  • Modular hardware and software architecture allows easy upgrades and enhancements
  • T-BERD® advanced stress patterns, intelligent repeater loop codes, and BERT patterns included
  • NetAnalyst control of Data Network Analyzer test devices

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.
