Use sp for Single Party signaling in an ESF (Extended SuperFrame) mode along with Feature
Group "D" high-speed modem services that require special software. The choice of boa (bill
on answer) sends a signal back to the office when the customer answers the phone, to start
billing for the call. An additional choice of lp-sr (loop-start short ring). Same as loop option
except the ringing time is 1 second ON and 2 second OFF instead of 2 second ON and 4 second
OFF (using existing option loop/lp-fd).
Selecting the plar option for the Mode of this port causes the system to offer d3 and d4, which
are the two common PLAR types. Both of these meet the pre-1988 and post-1988
specifications for PLAR circuits. If you select dpo as the Mode, the Type automatically
defaults to dpo.
If slc96 is selected for Mode, the two options supported are sp (single-party POTS) and uvg
(universal voice-grade).
Before activating this port, verify the behavior expected by both the station equipment and
remote central office equipment, and be sure the systems are properly configured.
Rx TLP
The Receive Transmission Level Point (TLP) setting controls the amount of gain or loss added
to the incoming signal after it is decoded to analog. To increase the signal level, set the Rx TLP
setting to a positive value (i.e., the larger the number, the more gain is added). To decrease the
signal level, set the Rx TLP setting to a negative value (i.e., the more negative the number, the
more the signal level is decreased). For example, an incoming signal at -5 dBm can be
increased to -3 dBm by setting Rx TLP to +2 dB. The Rx TLP range is -10.0 dB to +2.0 dB.
Tx TLP
The Transmit TLP setting controls the amount of gain or loss added to a voice signal from the
CPE before it is encoded to digital PCM. To increase the signal level, set the Tx TLP setting
to a negative value (i.e., the more negative the number, the more gain is added). To decrease
the signal level, set the Tx TLP setting to a positive value (i.e., the more positive the number,
the more the signal level is decreased). For example, an incoming signal at -5 dBm can be
increased to -2 dBm by setting the Tx TLP to -3 dB. The Tx TLP range is -10.0 dB to +5.0 dB.
