Acterna HST-3000

Acterna HST-3000
Option for VoIP
Voice over Internet Protocol (VoIP)
services are now being widely
deployed. Quick, efficient and cost
effective installation of these services
is therefore a key requirement. A
simple standards based field tool
enabling technicians to verify the
service, check voice quality and
troubleshoot problems is therefore an
essential tool to support VoIP service
deployment.
The HST-3000 VoIP tester is a versatile
field solution for VoIP service turn-up
and troubleshooting. Handheld,
rugged and easy-to-use, the HST-3000
can validate VoIP service connectivity,
feature availability and voice quality.
In addition, it provides comprehensive
features, including signaling, IP ping,
packet statistic and trace route
analysis to identify, diagnose and
sectionalize VoIP network and
equipment problems.
Advanced automated test functions,
custom scripting and one-button
operation also ensure consistent,
accurate and repeatable test methods
are used. This allows for rapid,
efficient and cost-effective delivery
of VoIP.

– CE-marked
VoIP Service Turn-up
To ensure successful VoIP service
turn-up, connectivity to the signaling
gateway, feature availability and call
quality must be proven.
The simplest and fastest way to verify
connectivity is to place an actual VoIP
call. The HST-3000 can emulate an IP
phone and supports placing and
receiving VoIP calls utilizing Cisco to
SCCP, SIP and H.323 signaling gateways. Calls can be placed to different
endpoints to verify translation
provisioning - IP phone to IP phone,
site to site, IP to TDM network, to a
provisioned automated test line or to
another HST-3000, either manned or in
AutoAnswer mode.
Both subjective and objective voice
quality measurements can be gathered
during these connectivity test calls. The
HST-3000 provides a packet-based
objective measurement of VoIP call
quality by analyzing delay, jitter, and
packet loss to generate a good, fair or
poor quality rating based on configurable Quality of Service (QoS) score
thresholds.
Additionally, the HST-3000 uses the
patented Telchemy single-ended live
call method to provide a real-time
assessment of subjective voice quality
in terms of both Mean Opinion Score
(MOS) and R Factor. The valuable data
provided by this analysis is compared
with the data from the objective measurements. This comparison helps to
quickly verify acceptable VoIP call quality. Call feature provisioning and the
availability of supplementary services
can also be verified during these calls.
The HST-3000 can also be used to turnup a VoIP service when it does not have
the required gateway signaling support. This procedure requires
end-to-end testing using two HST3000’s. One unit, set to AutoAnswer
mode, is connected to the router at the
customer premises. The second HST3000 unit is used to place calls back to
the first unit from different endpoints.
The first unit answers the call and plays
a pre-recorded message. Test measurements are obtained from the
pre-recorded message and displayed
on the HST-3000.

VoIP Troubleshooting
When a call is unsuccessful or the voice
quality is poor, the HST-3000 can be
used to identify and sectionalize problems.
With call-set-up problems it is essential
to have the ability to troubleshoot the
call signaling process. The HST-3000
provides real-time visibility of the
entire call set-up process. Signaling
message decodes and signaling error
messages are displayed allowing problems to be quickly and easily
pinpointed.
IP Ping and ICMP or UDP trace route
analysis can be performed to isolate
path/device connectivity problems
and sources of delay. Call throughput
can be measured. Additionally, Ethernet statistics are generated to aid the
diagnosis of call quality and identify
failed devices or network over utilization.

Reduce Costs, Increase
Productivity and Improve
Efficiency
The HST-3000 provides a number of
powerful features that can greatly
improve the VoIP service turn-up and
troubleshooting process, reducing
costs and improving productivity and
efficiency.
The HST-3000’s straightforward graphical user interface (GUI) greatly
simplifies the testing process, thus
reducing the amount of training needed for comprehensive testing.
The HST-3000’s pre-programmed tests
and customized scripts ensure that all
technicians follow the same procedures, speeding-up service delivery
and minimizing installation and testing
errors.
Standard Ethernet, USB and serial connections offer flexibility to easily
download software and offload stored
test results for later analysis.
In AutoAnswer mode two-ended testing across the VoIP network can be
accomplished by using a single technician. Additionally, one-button
automatic testing combined with support for all phases of VoIP service
deployment, reduces the number of
technicians required to turn-up and
troubleshoot service, as well as making it possible for non-experts to
operate tests.
