Pad Level—Transmit, Receive (Gain And
Attenuation Settings For Line Transmit And Receive)
This feature enhances the T1–E1 digital carrier transmission option, the pad level programming feature adjusts
voice levels for both the transmit and receive circuits in the individual channels. The choices include: Gain 2,
Gain 1, Nominal, Loss 1, Loss 2, Loss 3, Loss 4, and Loss 5. These settings provide an approximate +6 to -15
dB range of choices. Starting at the Nominal setting, each gain level represents an approximate 3 dB
amplification of the signal level from the previous setting, and each loss level represents an approximate 3 dB
attenuation of the signal level from the previous setting. Because digital transmission does not lose volume level
as readily as analog transmission does, it is likely that the receive level may be noticeably higher when using the
E1 option. Therefore, you may need to select a low setting such as Loss 2 for the voice level receive parameter
when programming this feature for E1 lines that are being used exclusively for voice transmission. Further, if
you choose a setting to increase the receive gain, you should carefully examine speakerphone operation. It is
possible to select a receive gain that will, under certain conditions, interfere with proper speakerphone
operation.
TAP (Flash)/Recall
When host system custom calling features are available via a hookflash signal while on line, the TAP button
functions as a hookflash button and generates a flash signal when the user presses it. When custom calling
signals are not available, the TAP button functions as a positive disconnect and recalls dial tone when the user
presses it. These features are mutually exclusive. The installer sets the desired function for the system by
programming action. With single–line proprietary telephones, the Tap function works for internal transferring
only. An access code is required to activate custom calling features.
Telephony Services Application
Programming Interface (TSAPI) Support
The FXT provides support for TSAPI applications. These applications are Novel Telephony Services*
applications developed by third-party software vendors. TSAPI applications run independently of the FXT yet
use its digital communications capability. The FXT Enterprise open architecture interface (OAI) data port
provides the hardware interface for the personal computer (PC) that runs the TSAPI software program.
Depending upon the TSAPI application and its functions, there may or may not be a need to reprogram the FXT
database feature parameters.

Through Dialing
An installer can connect external telephony equipment to the FXT through a proprietary interface device or
through an IST port. When the installer enables the through dialing feature, DTMF tones that the external
device generates pass through the interface equipment, the FXT system, and any line connection. Also see the
paragraph titled Off Premise Extension.
