3) Higher return loss values can be achieved by adding a reactive component to
4) The overhead level can be adjusted with the resistor R
5) Pin PTG = Open sets transmit gain to nom. 0.0 dB.
6) The specified insertion loss tolerance does not include errors caused by external components.
7) The level is specified at the two-wire port.
8) The two-wire idle noise is specified with the port terminated in 600
