Sometimes
it makes sense to follow the crowd. When you need to test T1, you need
a T-BERD--the tool whose name is synonymous with T1 testing.
Highlights
- Identifies
jitter; performs both highband and wideband measurements, and pinpoints
multiplexer and channel bank clock problems (T-BERD 211 only)
- Auto
configuration and results summary provide immediate identification
of framing, pattern, and error status
- Supports
CSU/NIU emulation for isolation of customer premises and network equipment
- Includes
automated and user-configurable stress pattern testing
- Performs
G.821, B8ZS, and Fractional T1 error analysis
- Measures
and analyzes pulse shape
- Brightly
lit front panel display is ideally suited for low light testing environments
- Lead
acid battery (T-BERD 209A) enables technician to test anywhere
for up to five hours without power generators or cords
- Repeater
Power Supply, T1 Repeater Extender, and Thermal Graphics Printer economically
add versatility to the TB209A/211
Features
The
T-BERD 209A/211 is a complete test and measurement solution for technicans
who install, test, monitor, and maintain T1 links and equipment. The
T-BERD 209A/211 can be optioned to perform the following tasks:
Equipment
Installation
- Verify
proper circuit operation from point to point
- Ensure
that loopback equipment responds to designated loopcodes
- Test
equipment under different traffic conditions using built-in fixed
and pseudorandom test patterns
Circuit
Maintenance and Problem Isolation
- Monitor
the circuit for intermittent problems that may become more serious
over time
- Avoid
the expense of taking the circuit out of service
- Analyze
live traffic without introducing any disturbances on the line
- Identify
and locate cable pair faults including shorts, bridge taps, load
coils, and other line impairments
Out-of-Service
Troubleshooting
- Stress
and analyze the network with point-to-point and loopback testing
Information
that technicians need to ensure optimum T1 performance is readily obtained,
quantified, and qualified by the T-BERD's comprehensive testing and
reporting options.
Jitter
Alarm and Trigger (T-BERD 211 only)--Front panel indicator
provides fast identification of jitter problems; jitter measurements
across the full 10 Hz to 40 kHz range facilitate isolation of multiplexer
and channel bank clock recovery problems.
Pulse
Shape Measurement and Analysis--Determine if the output of a network
element is acceptable, and evaluate customer premises and network equipment
adherence to pulse mask specifications at the point of sampling. Use
DSX and network interface masks to measure pulse shape and width, rise
time, fall time, undershoot, and overshoot.
Received
Signal Level Measurements--Analyze signal strength to diagnose transmission
problems caused by high/low signal levels.
G.821
Measurements--Perform error analysis per G.821 specification standards
to verify circuit quality. Capture data including unavailable seconds,
percent availability, degraded minutes, percent degraded minutes, severely
errored seconds, percent severely errored seconds.
Stress
Pattern Testing--Generate a full suite of patterns to rapidly locate
and isolate line problems. Patterns include:
- Automated
Multipattern Tests
Detect elusive bridge taps using automated BRIDGTAP sequence and
perform qualification tests with the user-configurable MULTIPAT®
sequence
- Long
User Pattern
Stress repeater ALBO circuits with 55 OCTET, T1 DALY, and other
long user test patterns
- All
Zero Stress Pattern
Identify circuits not configured for or incompatible with B8ZS data
- Intelligent
Repeater Loopcodes
Loop up and loop down individual addressable office repeaters and
line repeators, or transmit maintenance switch commands
ESF
Testing--Emulate and loop back network devices that accept either
in-band or ESF out-of-band (data link) loopback codes with ESF framing.
Decode ESF PRMs to confirm data link operation and network performance.
Emulate ANSI T1.403 compatible CSU equipment during circuit installation
and qualification.
Performance
Monitor NIU--SMARTNIU mode queries the Performance Monitor portion
of combined NIU/Performance Monitor equipment for the recorded T1 span
statistics, sets the Performance Monitor NIU clock to match the T-BERD's,
and clears NIU performance results.
CSU/NIU
Emulation--Isolate customer premises and network equipment during
installation and maintenance.
B8ZS
Detection--Quickly identify B8ZS encoded data via front panel indicator.
Fractional
T1 Analysis--Perform bit error rate tests on selected channels to
verify contiguous and non-contiguous bandwidth and route quality on
FT1 circuits.
