or over a decade, telecom technicians
have depended on the T-BERD 209A/211
F
T-Carrier Analyzer’s no-nonsense approach to T1
testing. The T-BERD 209A/211 is one of the most
widely used solutions for the spectrum of T1
troubleshooting and analysis needs. The reason is
clear. TTC packs this user-friendly instrument
with a robust feature set and backs it with a promise of customer care excellence.
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.
Introduction
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 provides 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 (FT1) 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 T-BERD 209A/211
T1 technicians
worldwide rely on
the T-BERD 209A/211
for the full spectrum
of monitoring,
troubleshooting,
and analysis needs.
Features
nformation technicians need to ensure optimum T1 performance is readily obtained, quantified, and qualified by
the T-BERD 209A/211’s comprehensive testing and reporting options.
I
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
• 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 repeaters, 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
• Decode ESF PRMs to confirm data link operation and network performance; emulate ANSI
T1.403 compatible CSU equipment during circuit installation and qualification
