6. CAUTION Before activating a port verify the behavior expected by both the station equipment and the remote central office equipment and ensure that you have the system properly configured Rx TLP The Receive Transmission Level Point setting controls the amount of gain or attenuation added to signals after they are decoded to analog signals To increase the signal level set the Rx TLP setting to a positive number i e the larger the number the more gain is added To decrease the signal level set the Rx TLP setting to a negative number 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 Acceptable values range from 10 0 dB to 2 0 dB Tx TLP The Transmit Transmission Level Point setting controls the amount of gain or attenuation added to signals after they are received from the local analog port and before they are encoded to digital PCM signals To increase the signal level set the Tx TLP setting to a negative number 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 number 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 Tx TLP to 3 dB Acceptable values range from 10 0 dB to 5 0 dB CODING The Coding setting sets the PCM c
