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.
Jitter Alarm and Trigger
(T-BERD 211 only)
• Front panel indicator provides fast identifica-
tion 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 equip-
ment adherence to pulse mask specifications at
the point of sampling
• Use DSX and network interface masks to mea-
sure 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 avail-
ability, 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 qualifica-
tion tests with the user-configurable MULTI-
PAT
 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 incom-
patible 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 opera-
tion and network performance; emulate ANSI
T1.403 compatible CSU equipment during cir-
cuit installation and qualification
