DSIM 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 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 modules is
a huge cost savings when doing system 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 fixedmodule.

The DSIM module can be programmed to operate as a single pilot AGC or a thermal AGC.
In the SPAGC mode the DSIM 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 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 module can be
programmed by the operator to have the upfront cable compensation settings at 9, 18, or 27
dB. The DSIM incorporates a bi-colored blue and orange LED that indicates the different
operational modes and settings of the DSIM during setup and operation.
The DSIM controller is used to set the DSIM 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.
The DSIM modules will be configured at the factory to have the default channel 88 digital
(609.00 MHz) pilot channel programmed. The DSIM controller is used to set the DSIM
modules to the customer selected pilot channel. In the setup of the DSIM module the pilot
channel that is programmed into the controller is downloaded into the memory of the DSIM
module. The pilot channel setting in the DSIM module can be changed in the future by
simply using a controller with the new desired pilot channel programmed.

DSIM Mode Definitions
Operation Mode
Definition
MGC
In the Manual Gain Control (MGC) mode the DSIM automatic gain
control is turned off.
The MGC mode is used during the setup of the station so that no
gain adjustments are made when the levels and slopes are setup.
AGC
In Automatic Gain Control (AGC) mode will make gain adjustments
to the station based on the level changes that occur on the pilot
channel.
TGC
In Thermal Gain Control (TGC) mode the DSIM will make gain
adjustments based on the changes in the internal temperature of
the station. In the TGC mode there is a selection of 9, 18 or 27 dB
for the amount of cable that is in front of the station. The dB of
cable setting is used to more accurately predict actual losses that
occur in the cable with the changes in the outside temperature.
Note: Thermal operational mode should not be used in amplifiers
that are pedestal mounted for underground networks. These units
operate on the assumption that cable temperature will change at
the same rate as amplifier temperature, while amplifiers mounted
in pedestals will vary in temperature far greater than the
underground cable temperature.

DSIM Mode Flow Chart
MGC mode:
This is the default mode for Amp. Setup
The controller LED will be solid blue
The DSIM LED will blink blue every half sec
Press MODE
once to start the
align process
Align Process:
This takes 45 sec. to lock on to the pilot CH.,
and save the pilot level
The controller will flash blue/ red
The DSIM will flash CH & type pattern
DSIM Locks on to the
channel successfully, it
starts the AGC mode
AGC mode:
The DSIM will maintain pilot level stability
The controller will blink blue every half sec.
The DSIM LED will give a channel &
ch type pattern
If the pilot is too
low, the DSIM
will use the
TGC process
If the pilot drop
more than 10
dB the DSIM
will go to
thermal fallback
Align Process: Thermal Fallback
If the Align Process fails check/ adjust levels or
reduce AGC PAD. return the MGC mode to try
again. DO NOT leave the DSIM in this mode.
The controller will flash blue/ red
The DSIM will flash blue/ orange
AGC mode: Thermal Fallback
The DSIM will calculate the output level until the
pilot channel returns. Then the DSIM will resume
AGC mode.
The controller will blink blue every half sec
The DSIM will flash blue/ orange
Press MODE once to return to MGC mode
TGC mode:
This mode calculates the output level based on
the internal Amp. Temperature
The controller LED will be solid purple
The DSIM LED will give the cable length
(9, 18, 27) dB and three long blinks
Press MODE
once from any
of these 4
modes to go to
TGC mode

Single Pilot AGC Standard Setup
The DSIM controllers will come preset to have a desired pilot channel stored in the memory.
The controller is used to set the DSIM module to the desired pilot channel by downloading
the pilot channel program into the DSIM module's memory during setup.
1.
Remove the RF module cover and install the DSIM-SS AGC module into theamplifier.
2.
If the outside temperatures are below 40ºF or above 80ºF, then the RF levels will need
to be adjusted to ensure that the full gain compensation range of the DSIM will be
available over the operational temperature range. If the outside temperatures are
between 40ºF and 80ºF then go to step 4.
3.
Using the table bellow adjust the RF output level at highest operating frequency by
pushing the “+" button to increase or the "-“ button to decrease the RF output level.
Pressing the button once is used for small increments, holding the button down isfor
large increments.
Below 0ºF
-2dB
Between 40ºF & 0ºF
-1dB
Between 40ºF & 80ºF
no change
Between 80ºF & 100ºF
+1dB
Above 100ºF
+2dB
4.
If the DSIM-SS has a slope POT use it to set the inter-stageslope.
5.
Check and set desired amplifier levels.
6.
Re-install the RF module faceplate.
7.
Plug the controller cable into the DSIM and plug the controller into the cable.
8.
The controller LED will then flash red / blue rapidly while the DSIM controller andDSIM
module completes the syncing process. This process will take approximately
2-3 seconds to complete.
9.
Once the controller LED stops flashing the red / blue sequence, it should then display a
constant blue, indicating that it is in MGC (manual) mode. Note: If the controller LED is
flashing blue, it indicates that it is in AGC mode; click “Mode” button two times to go
from AGC mode to MGC Manual Mode. In addition, if the controller LED displays a
constant purple, it indicates that it is in TGC mode; click “Mode” button once to go from
TGC to MGC Manual Mode.
10.
Press the 'Mode' once to go to MGC mode. Check that the output level and slope are
correct. Once level and slope are set, press “Mode” once to exit MGC (manual) mode.
