This feature enhances the

DXPTl

digital carrier transmission option,

Pad

the pad level programming feature adjusts voice levels for both the

transmit and receive circuits in the individual channels. The choices

Level-Transmit,

include: Gain 2, Gain 1, Nominal, Loss 1, Loss 2, Loss 3, Loss 4, and

Receive

Loss 5. These settings provide an approximate

to -15

range of

choices. Starting at the Nominal setting, each gain level represents an

approximate 3

amplification of the signal level from the previous

setting, and each loss level represents an approximate 3

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

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

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.
