4.2 Installation Requirement Guidelines

Here are a few guidelines to keep in mind when installing the COM2000 system that will

minimize the potential problems that the system could be expected to encounter.

4.2.1 General System Guidelines

 The optimum RF levels at the input of a SWM module are -30 to -50 dBm per

transponder.

 The optimum RF input levels for the COM46 cards are -25 to -45 dBm per transponder.

 COM46 cards can only be connected to a SWM module, they will not support a

multiswitch.

 COM46 and COM46-FLX cards contain 8 tuners and must be supplied with a dedicated

SWiM output.

 The COM2000 system is designed to operate properly in ambient environments of 104 °F

(40°C) or less.

 The system will not be capable of streaming any video on any channel besides 100 until

the COM46 cards have been authorized by DIRECTV.

4.2.2 System Integrator Guidelines

 The system integrator must provide a mapping of TV channels to COM46 slots and

tuners.

 The COM2000 will generally be preconfigured, including the appropriate RF and IP

connections to a QAM6 edgeQAM device.

 Any necessary DIRECTV SWiM units should be supplied by the System Integrator.

4.2.3 System Operator Guidelines

 It is recommended to use the StarRoute SRSN4 Normalizer within the property’s RF

plant before the distribution panel in order to normalize the B band K

signals with the

traditional K

satellite signal levels. B band signals are generally higher-powered and

tend to saturate the converters unless the installer is very careful regarding input signal

levels going into the distribution network.
