EZ-Tester T-Carrier Test Set
Information
General
The portable hand-held EZ-TESTER® DS, is designed to perform
in-service and out-of-service
testing and monitoring of DS1circuits, and out-of-service
testing of 4 -wire DDS communications
equipment and circuits. It is used during installation to
verify acceptable performance and during
maintenance to isolate problems to the communications
components or end user equipment. The EZ-
TESTER DS incorporates the following design features:
Rugged metal case minimizes damage from drops and similar
accidents
Weather-resistant construction protects Test Set in wet or
dusty field conditions
Menu driven setup and operation for ease of use
Auto configuration feature determines line characteristics
and reduces setup time
Can be configured as a single or dual line Test Set.
Dedicated storage for eight custom test setups
Includes 26 stored test patterns vital to DS1 testing
Controls and simulates CSU / NIU loopback functions
Includes built in speaker, with jack for an optional headset
Provides DS0 channel access
Software upgrades can be field installed using OnCall® with
a telephone line and modem
1.2 Functional Description
The EZ-TESTER DS performs comprehensive testing of DS1,
4-wire DDS circuits and
equipment, plus optional line parametric testing. As a T1
test set, it can be configured with single dual T1 test
ports with single or paired transmitters and receivers. The
receiver section can monitor
customer data or received test data to identify current line
coding and framing information, and detect and display
standard alarms and errors. The transmitter section can be
used to send standard
test patterns, inject errors into the data stream, and
generate loopback commands to NIUs and CSUs
to enhance isolation of network impairments. Dual transmit
and receive jacks allow simultaneous directional monitoring
and the ability to perform a drop and insert with a single
instrument.
As a DDS Test Set, the EZ-TESTER DS provides full
out-of-service testing capabilities for 4-wire
DDS local loops. When connected to terminate a 4-wire DDS
local loop, the Test Set can autoconfigure
to match the loop rate, identify an existing test pattern,
and confirm the status of the secondary status
and test pattern. It will also detect alarm and error
conditions; transmit typical DDS test patterns;
inject errors and alarms; decode control bytes; perform
local or remote loopback functions; and allow
frame relay testing from a DDS access point.
The optional line parametric test feature enables the test
set to perform line level and frequency
measurements, noise measurements, spectrum analysis, time
domain reflectometry tests, and test lead
calibration.
During operation, a capture memory stores selected events,
periodic test summaries, and end
of test results. All events are date and time stamped from
an internal real time clock and can reviewed locally,
remotely, or output to a printer. Eight user defined test
setups can be stored and
recalled for ease of operation. An auto configuration
function is available to determine line
characteristics. Remote control operation and printer output
is provided through an auxiliary RS-232
port.
