Troubleshooting

Defined

The identification and resolution of problems, especially problems

of a technical nature

The process of solving problems, especially complicated problems
in a system

number of steps possible by partitioning the system into
manageable sections, using the symptoms to pick a starting point

and following the signal through the various sections until the

offender is identified

THE COM1000/COM2000 INSTALLATION

For troubleshooting purposes the COM1000/COM2000 installation
can be split into three main sections.

o The RF Plant

o The Head End

o The Distribution Network

Our first goal in troubleshooting the system is to determine which
of these three areas the problem most likely resides in.

THE RF PLANT

All COM1000/COM2000 RF plants should be designed and installed

following the practices outlined in the latest version of this DIRECTV

document or the current replacement wherever possible.

THE RF PLANT

The COM46 card has 9 tuners and is SWM ONLY, NO multiswitch RF

plants can be used with the COM46 card

This means that every COM46 card requires a complete SWiM 8 tap
exclusively

When adding COM46 cards in existing COM1000 systems with

COM24 and/or COM24-FLX cards the rules and guidelines in the

DIRECTV COM24/SWiM Use Cases and Installation Constraints
document and the Technicolor COM24 and COM24-FLX Application

Note 03132013 documents should be followed at all times

RF PLANT COMPONENTS

The RF plant may include some or all of the following

components:

• The Dish/LNB and mount

• Polarity locker/LNB power supply

• Leveling amplifier

• SWM module and power supply

• Multi-switch panel and power supply

• B Band converters

• RF Splitters

• Various cabling and connectors
