HP OmniBER 717 Communications 2
Performance Analyzer
The HP OmniBER 717 provides solutions for broadband testing from
the physical layer up to service layers. The modular nature of this flexible
instrument allows it to be configured to match a wide range of applications
including installation and maintenance and manufacturing test
applications. It can operate at all the most common ANSI and ETSI
wide-area transmission rates.
In-Service ATM Analysis
Use the Channel View feature to find and identify up to 1023 active virtual
channels on an ATM link, including even single cell events.
Observe real-time cell rate/count simultaneously on all found channels.
Post analysis of each active channel is performed automatically to identify
the AAL or OAM cell type in use; ATM layer alarms are also displayed.
Perform detailed analysis at the ATM or higher layers. Monitor
real-time in-service cell delay variation graphically using 1-point CDV
measurements and count non-conforming cells to I.356. Analyse I.610
performance management OAM cells to obtain cell loss and misinsertion
results from live traffic. Analyse AAL errors to gain a useful indication
of problems at the ATM layer.
Out-of-Service ATM Analysis
Generate and analyse O.191 Test Cells to obtain measurements for
2-point CDV, cell loss, cell misinsertion and cell errors, according to I.356.
Generate up to ten virtual channels, each with a user-definable profile of
constant, Poisson or bursty traffic. In addition to Test Cells, generate and
analyze single cell or cross-cell (segmented) pseudo-random binary
sequences. Inject single or double header errors or payload impairments
and generate and identify ATM layer alarms using the F4 and F5
OAM flows.
Physical Layer Features, including Jitter
Analyze physical layer errors, perform G.826 analysis and generate physical
layer impairments, generate and identify physical layer alarms. Measure
the received clock rate and optical power, and offset the analyzer's
internally-generated clock rate. Generate and analyze physical layer jitter
which, together with the frequency offset capability, make this analyzer
an important tool for checking the jitter tolerance of ATM interfaces.
Ethernet Connectivity
Check LAN over WAN connectivity on Ethernet networks. Use "pings"
and Ping History to check the end-to-end service.
