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.

The DSIM-SG 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-SG
modules to the customer selected pilot channel. In the setup of the DSIM-SG module the pilot
channel that is programmed into the controller is downloaded into the memory of the DSIM-SG
module. The pilot channel setting in the DSIM-SG module can be changed in the future by simply
using a controller with the new desired pilot channel programmed.
3. 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 control 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.

8. Single Pilot AGC 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-SG module to the desired pilot channel by downloading the
pilot channel program into the DSIM-SG module's memory during setup.
1. Remove the RF module cover and install the DSIM-SGAGC module into the amplifier.
Then re-install the RF module cover.
2. Turn S1 switch to manual (position 2).
3. Using the Manual Back off pot:
a. Turn output level to MAX gain
b. Back off:
i. 3.2 dB @ 547MHz
ii. 4.1 dB @ 750MHz
iii. 4.6 dB @ 870MHz
4. Turn S1 switch to position 3.
5. Insert AGC PAD: 0dB.
6. Set the Input and Output levels.
7. Attach cable and controller to the DSIM-SG, the controller light should be solid blue
indicating manual mode (if not press mode button until it is).
8. If the outside temperatures are below 40ºF/4.4ºC or above 80ºF/ 26.7ºC, 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/4.4ºC and 80ºF/ 26.7ºC then go to step 14.
9. Measure and record the RF output level of the amplifier at the highest operating frequency.
Using the table bellow adjust the RF output level 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 is for large increments.
Below 20ºF (-6.7ºC)

10. After the RF level adjustment of the DSIM AGC module has been made, adjust theRF
output level to the value recorded in step 9 by adjusting the input pad value.
11. All DSIMs have a thermal fallback default setting of 27 dB. To change it, push the MODE
button twice. The controller LED should be purple indicating TGC mode. There are three
TGC factor options: 9 dB, 18 dB and 27 dB. The blinking pattern should indicate 27dB.
Push the '-' button once for 18 dB or twice for 9 dB. Check the blink pattern to verify thermal
fallback value.
a. Blink patterns for TGC
i. 27 dB (2 fast blinks, pause, 7 fast blinks, pause, 3 long blinks)
1. For more than 1000ft of cable before the amplifier
ii. 18 dB (1 fast blink, pause, 8 fast blinks, pause, 3 long blinks)
1. For 600ft - 1000ft of cable before the amplifier
iii. 9 dB (9 fast blinks, pause, 3 long blinks)
1. For less than 600ft of cable before the amplifier
12. Press the 'Mode' once to go to MGC mode. Check that the output level and slopeare
correct.
13. Press “Mode” once to start the Align process. The LED on the controller will flash blue and
red (about 45 seconds) until the alignment process has completed.
14. When the alignment process has completed, the controller LED should blink blue indicating
that the DSIM is now in the AGC mode. If the indicates AGC mode skip to step14.
15. If the LED does not change to blinking blue, and instead the DSIM LED flashes blue and
orange the pilot signal is either too high or too low going into the DSIM. Try Decreasing the
AGC PAD value by 3 dB. Press the mode button 3 times to try alignment process again.
16. You can check the LED on the DSIM-SG Module to make sure the channel number is right.
Refer to section 10 for pilot channel blinking count overview.
17. Remove the interface cable from the amplifier, and the DSIM-SG is allset.

9. Thermal AGC Setup
In setting up the DSIM-SG modules as a Thermal AGC the cable length dB values will need to be
adjusted to match the dB of cable that is in front of the station. The DSIM controllers will come
preset to have a default cable length setting of 27 dB in the memory. The controller is used to
set the DSIM-SG module to either 9 dB, 18 dB, or 27 dB of cable by simply clicking the “Increase”
or “Decrease” buttons on the controller.
1. Remove the RF module cover and install the DSIM-SGAGC module into the amplifier.
Then re-install the RF module cover.
2. Turn S1 switch to manual (position 2).
3. Using the Manual Back off pot:
a. Turn output level to MAX gain
b. back off:
i. 3.2 dB @ 547MHz
ii. 4.1dB @ 750MHz
iii. 4.6 dB @ 870MHz
4. Turn S1 switch to position 3.
5. Connect the DSIM controller to the DSIM-SG AGC module with the interface cable
assembly. The controller LED will then flash red / blue rapidly while the DSIM controller
and DSIM-SG module completes the syncing process. This process will takeapproximately
2-3 seconds to complete.
6. Press 'mode" until the controller LED is constant purple (TGC mode).
7. All DSIMs have a TGC default setting of 27 dB. There are three TGC factor options: 9 dB,
18 dB and 27 dB. The blinking pattern should indicate 27dB. Push the '-' button once for
18 dB or twice for 9 dB. Check the blink pattern to verify TGC value.
a. Blink patterns for TGC
i. 27 dB (2 fast blinks, pause, 7 fast blinks, pause, 3 long blinks)
1. For more than 1000ft of cable before the amplifier
ii. 18 dB (1 fast blink, pause, 8 fast blinks, pause, 3 long blinks)
1. For 600ft - 1000ft of cable before the amplifier
iii. 9 dB (9 fast blinks, pause, 3 long blinks)
1. for less than 600ft of cable before the amplifier
