one error each time the error key is pressed) or a rate of insertion from 10-1 to 10-7
errors can be selected. (Ex: 10E-1, inserts automatically one error at each 10 bits). For
the FAS and CRC errors, the user can: use the ERROR key to input SINGLE errors, in
the SINGLE mode or choose automatic error insertion, with bit error rate of from 10

Use the ← or → keys to select.
•
Line Code : Allows the user to choose HDB3 or AMI line codes. Use the ← or → keys
to select.
•
Termination : It is possible to choose the cable termination impedance as 75 ohms
UNBAL, 120 ohms BAL, HIGH-Z UNBAL or HIGH-Z BAL. Use the ← or → keys to

•
Tx Clock Source : Selects the source of the transmission clock. There are three options
that can be selected using the ← or →keys:

External clock: the transmit data are in sync with the external circuit clock,
which must be set up to internal or regenerated clock. The external clock must be
provided by the V.35 interface
(Note: connect the TSW200E1 ground to the
ground of the equipment which is providing the clock).

Internal clock : the Test Set itself provides the transmission clock. In this case,
the external circuit must be prepared to receive external clock.

From Rx : the clock is regenerated from reception.
•
Clock Deviation : Allows programming the clock deviation from -50 to +50 ppm.

Test Period : Defines the test duration. It can be CONTINUOUS or timer limited. This
timer can be set for up to 10000 hours. To choose between these two options use the ←
or → keys. The timer can be edited by pressing DATA. When editing the timer the
starting test time must be set.
•
Histo Resolution : Allows the user to choose the histogram resolution as MINUTES or
HOURS. To choose between these two options use the ← or → keys.
•
Drop & Insert : This option is used to take out or to insert data from the selected
timeslot (s) from another interface. The choices are OFF OFF, ON OFF, OFF ON or ON
ON, using the ← or → keys. The ON state indicates that the mode is active and the OFF
state indicates that the mode is inactive.
•
Interface : This option is available only when Drop&Insert is not set for OFF OFF. It
selects which interface will be used to drop or to insert data. It is possible to choose
RS232, V35, V36, X.21 or RS530.
•
Alarm & Err Buzz : Allows the user to turn on or off the alarm and error buzzers. The
choices are OFF OFF, ON OFF, OFF ON or ON ON. When ON, the corresponding
