DTMF
1 - Introduction
The TSW200E1 DTMF Module allows si ulating the process of calling an end user using
DTMF. The digits can be anually inserted using the equip ent keyboard or auto atically by
eans of a user-selectable nu ber of up to 16 digits. The user can also edit the CAS pattern used
and the following tone characteristics: active ti e, interval ti e between tones and tone level. The
only interface used in this odule is the G703-2M.

2 - DTMF Module Operation
2.1 - DTMF test Configuration
The configuration of this odule is very si ple and consists of two screens. To navigate
between the two screens, use the <F1> (BACK) key or <F4> (NEXT) key. The <F3>(MODULE)
key returns to the odule screen.
After selecting the DTMF odule at the odule screen, the first configuration screen is
shown, as displayed in the figure below. At this screen, the user progra s the line para eters. To
odify any para eters, ove the cursor up to the para eter line that is to be changed and use the
← and → keys to odify the para eters.

•PCM: Selects the fra e structure. The structures are PCM30 and PCM30C.
•Termination: The cable ter ination i pedance can be chosen as 75 oh s UNBAL,
120 oh s BAL, 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
trans itted nor ally or INVERTED, where the bits are inverted.
•Channel: Channel in which the equip ent will initiate the calls.
The next configuration screen, shown in the following figure, selects the para eters for the
trans itted tones and CAS signalization.

•Speed Dial: It is a sequence of up to 16 digits (including nu bers fro 0 to 9, * and
#) that is user-selectable so that the tones corresponding to these digits are
trans itted in sequence. To edit the nu ber, press the <DATA> key with the cursor
pointing to this para eter and, at the editing screen, use the alphanu eric keys to
enter the desired nu ber. The <CLEAR> key clears editing. These nu bers can
have up to 16 digits. Shorter nu bers are allowed.
•On Hook: Selects the CAS pattern trans itted to indicate that an unused channel is
either in the On Hook or Idle status. To edit this value, press the <DATA> key with
the cursor pointing to this para eter and, at the editing screen, use the 0 and 1 keys
to enter the desired nu ber. The <CLEAR> key erases the value.
•Off Hook: Selects the CAS pattern trans itted to indicate that a channel that is
being used is in the Off Hook or Seize status. To edit this value, press the <DATA>
key with the cursor pointing to this para eter and, at the editing screen, use the 0
and 1 keys to enter the desired nu ber. The <CLEAR> key erases the value.
•DTMF Level: Selects the level or a plitude of the tones that will be coded and sent
in the chosen channel. The level can be selected fro 0 to -53 dB . To odify this
para eter, use the ← and → keys.
•DTMF On: Selects the active ti e of a DTMF tone. It can be chosen fro 35 to 999
illiseconds. To edit this para eter, use the ← and → keys or press the <DATA>
key.
•DTMF Off: Selects the silence ti e between sending the DTMF tones. It can be
chosen fro 35 to 999 illiseconds. To edit this para eter, use the keys ← and →
or press the <DATA> key.
2.2 - Performing the DTMF test
The test can be started after all the para eters have been chosen. To do this, si ply press the
<START/STOP> key at any of the two configuration screens.
The running test presents a single screen, displayed in the following figure.

The channel being used, its status (On Hook or Off Hook) and an event log are displayed.
Pressing the <F1> (HOOK) key changes the channel status fro On Hook to Off Hook or
fro Off Hook to On Hook.
The <F2> (DIAL) key trans its sequentially the tones for the Speed Dial para eter digits.
The length of the tones is defined by the DTMF On para eter and the silence interval between each
tone is defined by the DTMF Off para eter.
The <F3> key sends a WINK sequence (On Hook, Off Hook, On Hook) if the channel status
is On Hook or a FLASH sequence (Off Hook, On Hook, Off Hook) if the channel status is Off
Hook.
The <F4> key freezes the event log and allows the navigation using the ←, ↑, → and ↓ keys.
The <CLEAR> key clears the ti e log, erasing the events that occurred.
The event log presents the o ent of the occurrence of each event with illisecond
precision and an event description. Events are:
•CAS changes in the trans ission and in the reception. In this case, the new ABCD
bits values corresponding to the observed channel are shown.
•Sending of a WINK or FLASH sequence
•Sending of a keyboard tone
•Sending of the Speed Dial digits
All data received are sent to the equip ent loudspeaker. The data sent by the TSW200E1
during the call are the generated tones or audio entering the icrophone. While the equip ent sends
no tone (or the silence of the interval between tones), any data entering the icrophone are sent.
The test ends by pressing the <START/STOP> key.
