Pad Level-Transmit, Receive
(Gain And Attenuation Settings For Line Transmit And Receive)
Description:
This feature enhances the Tl-El 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 Tl 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 Tl 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.
