2. DSIM-SG AGC Module & DSIM Controller Overview
The Digital Station Intelligence Manager (DSIM) product line is the next generation of automatic
gain control modules that provides the outside plant maintenance team with station diagnostic
tools that are unprecedented in the industry. The DSIM-SG AGC module is agile that allows the
program settings to be modified at any time to change the pilot channel number and type from
analog to digital or to change the operational mode into the SPAGC, Thermal AGC or manual
modes of operation. Having this flexibility to reprogram the DSIM-SG modules is a huge cost
savings when doing system pilot channel modifications over the fixed SPAGC or T-bode modules
since only the program settings need to be changed instead of having to change out the entire
AGC fixed module.
The DSIM-SG module can be programmed to operate as a single pilot AGC or a thermal Bode
AGC. In the SPAGC mode the DSIM-SG can be programmed to use either an analog or digital
pilot signal from channels 52 to 142. If the pilot channel is lost, the DSIM-SG module will default
into a thermal TGC mode and then return to the single pilot SPAGC mode automatically once the
pilot channel has been restored. In the thermal AGC mode the DSIM-SG module can be
programmed by the operator to have the upfront cable compensation settings at 9, 18, or 27 dB.
The DSIM-SG incorporates a bi-colored blue and orange LED that indicates the different
operational modes and settings of the DSIM-SG during setup and operation.
The DSIM controller is used to set the DSIM-
SG module’s pilot channel and to change into the
different operational modes during the amplifier setup. The bi-colored blue and red LED
indicator's blinking patterns will denote the current optional mode setting.
