and press the DATA key. The editing mode screen will be displayed. Using the 0 and 1
keys, edit the desired word. To end editing, press <F4> (ENTER). To cancel the editing,
press <F1> (EXIT).
•
Polarity : Determines signal polarity. It can be normal or inverted. For inverted polarity,
every pattern bit value is inverted. To choose, use the ← or → keys. This parameter
allows the user to select separately the polarity of the transmit and receive signals as
normal (NORM) or inverted (INV).
•
Tx Clock Source : This parameter defines the clock source. To choose, use the ← or →
keys. The clock source can be:

INTERNAL: when the Test Set itself provides the transmission clock.

EXTERNAL: when the transmission data are synchronized with an external
circuit clock, which must be set up for internal or regenerated clock. For G.703-
2M, the external clock must be provided by the V.35 interface (the user must
connect the TSW200E1 ground to the clock-providing equipment ground).

FROM RX: when the transmit data are in sync with the modem-provided clock,
this must be set up for internal or regenerated clock. This option can be used for
the G.703-2M interface only.

RECOVERED: when the clock is regenerated from reception. This last option is
available only for the G.703-64k interface.
•
Tx Rate : Chooses the transmission rate, which varies from 1200 bps to 2048 Kbps,
using the ← or → keys. If the USER option is chosen, edit the rate up to 10 Mbps. To
edit, choose the USER option and press the <DATA> key. Using the alphanumeric keys,
enter the desired value for the transmission rate. To end editing, press <F4> (ENTER).
To cancel editing press <F1> (EXIT).
•
Test Period : Chooses the test period. The test can be continuous, lasting for a given time
or for a certain number of blocks. To select, use the ← or → keys. If the timer option is
chosen, it is necessary to edit the test time (duration) and the starting time (time to
begin). To do that, press the DATA key when the cursor points to the proper line. If the
test is to be started immediately, set the time to begin to zero.
•
Error insert : This option allows selection of the bit error insertion mode. It can be
SINGLE (inserts one error at each time the ERROR key is pressed) or it can select a rate
of errored bits from 10E-1 to 10E-7. To choose, use the ← or → keys.
•
Histo Resolution : Selects the resolution for the result histograms. The histograms can
have resolution in minutes or hours. To choose, use the ← or → keys.
•
Alarm & Error Buzz : Allows the user to activate or deactivate the alarm and error
buzzers. The options are OFF OFF, ON OFF, OFF ON or ON ON. When set to ON, the
buzzer is active and when set to OFF, the buzzer is inactive. To choose, use the ← or →
keys.
•
Loopback : Allows the equipment to be configured to perform a local loopback test
(LOCAL), remote (REMOTE) or no loop at all (NONE). For the local loopback, the
same data transmitted by the equipment are internally sent to its reception. So, the
equipment can be in sync when the test is started, without receiving external data. For
the remote loopback, the equipment sends the data it is receiving. Available on
hardwares E or newer.
•
DTR/RTS : Allows the user to activate (ON) or deactivate (OFF) both control signals
DTR and RTS. Available on hardwares I or newer.
•
Clock Deviation: When the used interface is G.703-2M, allows the user to choose the
transmission clock deviation which varies from -50 to+50 ppm.
