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.

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

Installation Guide Rev A

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.

Remove the RF module cover and install the DSIM-SS AGC module into theamplifier.

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.

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.

If the DSIM-SS has a slope POT use it to set the inter-stageslope.

Check and set desired amplifier levels.

Re-install the RF module faceplate.

Plug the controller cable into the DSIM and plug the controller into the cable.

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.

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.
