T-BERD 950 User’s Guide
Designed to make routine test setup simple and intuitive, Task
Navigated Testing (TNT) guides field service technicians through
typical testing scenarios quickly, easily, and accurately. TNT is
designed around the tasks and terminology employed by the
technician. Basic T1 TNT configurations are described in “Testing
with the T-BERD 950” on page 48.
TNT is for the technician who performs typical field service turnup
and troubleshooting procedures. However, for those who encounter
non-traditional testing scenarios, the T-BERD 950 is still entirely
custom configurable using Manual Setup mode. Either way, the
T-BERD 950 can provide full featured testing capabilities based on
your needs.

Modes of Operation
The baseline T-BERD 950 Communications Analyzer is a T1/FT1
Bit Error Rate (BER) test set that offers several options that enable it
to become a full-featured, multi-service test instrument. It has two T1
interfaces: T1-LINE and T1-EQUIPMENT. Each interface consists of
an independent receiver and transmitter. The interfaces can be
configured for various applications.
The T-BERD 950 can operate in four modes:
■
Terminate Mode
■
Drop and Insert (D&I) Mode
■
Dual Monitor (Mon) Mode
■
Line Loop Back (LLB) Mode
Modes of Operation
7
Terminate Mode
This mode separates the transmit and receive sides of a T1 path. The
input signal is terminated at the receive side, and a totally independent
signal is generated for the output. You can use either the LINE Tx/Rx
pair or the EQUIPMENT Tx/Rx pair.
In the event of power loss (i.e., no AC power and no batteries)
to the T-BERD 950, the LINE and EQUIPMENT pairs are
automatically cross connected to prevent loss of service.

Chapter 2 — Instrument Setup and Description
Drop and Insert (D&I) Mode
This mode enables the T-BERD 950 to access specific channels from
the T1 line while leaving the other channels unaffected. The transmit
and receive side of the T1 path are paired. As shown in Figure 1, the
input signal is received, Bipolar Violations (BPVs) are corrected, the
signal is regenerated, and new data can be inserted onto specific
bandwidths before the signal is sent to the output. No data is inserted
on the transmit path unless the associated receiver has frame
synchronization. The D&I mode signal paths are illustrated in Figure
1.
Line Equipment

Dual Monitor (Mon) Mode
This mode measures signal parameters, monitors traffic from a
resistor-isolated DS1 monitor point, or bridges onto the line. One (1)
or two (2) receivers may be used. If two (2) receivers are used, the
LINE and EQUIPMENT receivers are monitored simultaneously.
Line Loop Back (LLB) Mode
This mode places the T1 path into Full Loop Back configuration,
which loops the incoming data back out the transmitter while
enabling the receiver to monitor the incoming signal (BPV errors are
not corrected). The LLB mode signal paths are illustrated in Figure 2.

Self Loop Mode
When the T-BERD 950 is placed in Self Loop mode (press
key), a set of relays is activated. These relays are designed to

pass the incoming signal through the T-BERD 950. The signal path is
from Rx LINE to Tx EQUIPMENT, and from Rx EQUIPMENT to
Tx LINE. This is the same configuration as for D&I Mode.
If a D&I test is being performed, and the T-BERD 950 is placed in
Self Loop mode; the incoming signal still passes through it without
interruption. If it is in Terminate Mode, where the configuration is Tx
LINE to Rx LINE, the relays have no effect. The relays remain active
when the unit loses power or is powered off.

Exterior Inspection
Inspect the external portions of the instrument for damage, wear, and
loose or missing parts. Check all parts thoroughly to verify correct
operation and performance.
Any deficiencies found that could cause personal injury or
lead to further damage indicate that the unit should not be
used.
Exterior Cleaning
Loose dust on the outside of the instrument can be removed with a
soft cloth. Remove any dirt that remains with a soft cloth dampened in
a mild detergent and water solution (e.g., Miller Stephenson Cleaner
MS-260).
T-BERD 950 User’s Guide
Do not use abrasive cleaners on the Large Graphical Display
or Two-Line Display screen as the screens could be
scratched. Do not get moisture inside the instrument.
Use only enough water to dampen the cloth. Any accumulated dust
and dirt in the fan input area can be removed with a vacuum.

Performing T1 BERT Turn-up in CSU Emulation
The objective of a T1 BER test is to perform T1 qualification, such as
a QRSS BER test. In the passive loopback mode, you can view
various test results while the test is running. This provides a method
of isolating the problem to a specific piece of equipment or section of
the loop. This is performed as an out-of-service test in TERMINATE
mode. Table 8 provides detailed test scenarios, TNT setup items, and
test results.

SEND LOOPBACK
(NIU Access)
In this scenario, the T-BERD 950 is being used to
generate a loopback code to a device located at either
the customer premise (e.g., a CSU) or within the
network. The unit sends an HDSL loop code to a
doubler or HTU-C, or sends a loop code to an NIU or
smart repeater. The technician is typically in control
of the test.
RECEIVE LOOPBACK
(NIU Access)
In this scenario, the T-BERD 950 is being used as a
loopback device. Ideally, you are waiting for a
loopback code (e.g., a CSU loop) to be sent from a
centralized tester or from a test set located in the
Central Office (CO). The remote tester is typically in
control of the test.
STRAIGHTAWAY
(NIU/DSX access)
In this scenario, the T-BERD 950 is being used at the
customer premise, while another test set is located at
the far end, typically the CO at a DSX patch panel.
Testing and analysis is performed in both directions.

TNT Example
In this scenario, your customer has ordered T1 service, and you will
need to perform the final acceptance turnup procedures. After you
install the smart jack (NIU) at the customer premises, you must run a
straightaway (end-to-end) BER test with a CO technician to verify
service. This common test scenario requires two testers.
Because this is a common test application, you can use the TNT
mode.

Using the Manual to Setup Configurations
The remaining chapters are organized by interface and option. Each
chapter provides both TNT and Manual Setup information. Unless it
is related to a specific option (i.e., Frame Relay), the configuration is
described in the appropriate interface section. For example, even
though you can test the frame relay option with the T1 or DDS-LL
interface, it is only available if you have the option (regardless of the
interface). Therefore, all frame relay TNT scenarios are described in
the Frame Relay Option section. This same principle applies to the
Primary Rate ISDN Option as well.
59
In each option/interface chapter, the TNT tasks are described and the
tests within each task are presented in a table. This table explains the
specific test as is pertains to the associated task. Also provided in
these tables are the configurable parameters in the TNT Setup view
and the results in the TNT Results view. The TNT Setup parameter
defaults are listed in parentheses () beside the TNT Setup parameter.
Following the TNT descriptions are the Manual Setup parameter
descriptions for the Interface and Test Type views, in addition to
detailed results information by category. Because the setup
parameters and results for TNT are a subset of those for Manual
Setup, refer to the Manual Setup section for definitions of these items.

while leaving the other channels unaffected. Typically used at
a DSX-1 patch panel or similar T1 access point.
MONITOR
— Selects Monitor mode, which enables the
analyzer to measure signal parameters or monitor traffic from
a resistor-isolated DS1 monitor point, or bridge on to the line.
Use this mode to analyze live traffic without disrupting the
circuit. You can monitor one or two circuits at a time. BER
testing cannot be performed in Monitor mode.

because both are capable of supplying power to the
span. When
POWER DOWN
command is set, the
command is received and turns the power off the
span. As long as the repeater is receiving this
Power Down sequence command, it will continue
to power down. However, when the command is no
longer being received (using
POWER UP
), the
power is then restored. This can take up to 5
seconds. This function is typically used to reset the
line, particularly if a repeater in loopback cannot
be looped down via commands.
SEQ LOOPBACK
— (REPEATER COMMANDS

span in sequence, starting with the repeater nearest
the T-BERD 950, and proceeds down the span,
regardless of the repeater’s address. Pressing
