1 - Introduction
The TSW200E1 DTMF Module allows simulating the process of calling an end user using
DTMF. The digits can be manually inserted using the equipment keyboard or automatically by
means of auser-selectable number of up to 16 digits. The user can also edit the CAS pattern used
and the following tone characteristics: active time, interval time between tones and tone level. The
only interface used in this module is the G703-2M.

DTMF test Configuration

The configuration of this module is very simple andconsists of two screens. To navigate
between the two screens, use the (BACK) key or (NEXT) key. The (MODULE)
key returns to the module screen.
After selecting the DTMF module at the module screen, the first configuration screen is
shown, as displayed in the figure below. At this screen, the user programs the line parameters. To
modify any parameters, move the cursor up to the parameter linethat is to be changed and use the
← and → keys to modify the parameters.

PCM: Selects the frame structure. The structures are PCM30 and PCM30C.
Termination: The cable termination impedance can be chosen as 75 ohms UNBAL,
120 ohmsBAL, HIGH-Z UNBAL or HIGH-Z BAL.
Line Code: Allows choosing the line code as HDB3 or AMI.
Polarity: Selects the polarity signal as NORMAL, where the selected pattern bits are
transmitted normally or INVERTED, where the bits are inverted.
Channel: Channel in which the equipment will initiate the calls.

The next configuration screen, shown in the following figure, selects the parameters for thetransmitted tones and CAS signalization.
