When an AGC is installed in the station, it is an AGC station. In an AGC station,
switch S1 provides two setup modes and one operational mode.

When there is no AGC installed in the station, it is a thermal station. In a thermal
station, switch S1 provides two operational modes.

Switch S1 Positions for AGC Stations
The mode you decide to use to balance an AGC station determines the position in
which you place switch S1.
which you place switch S1.
Position 1 - Selects thermal setup mode
Position 2 - Selects manual setup mode
Position 3 - Selects AGC operational mode
Note: AGC operational mode is used only after the station has been initially
balanced in either thermal or manual setup mode.

Bode Network
The Bode Network, or Bode, is an interstage variable attenuation and slope network
whose loss characteristics are driven by DC control voltage.
