2 INTRODUCTION 2.1 OVERVIEW This handbook describes how to install and configure the P300 Series Satellite Modems. This includes the original P300, the P300 Turbo, P310 L-Band and P311 mixed L-Band/IF Modems. Where ever reference is made to the P300 or P300 Series modem it applies to all products unless specifically noted. The P300 Series may be supplied equipped with different feature sets to suit different applications. This means that the mix of features available in any modem (such as Drop/I

2.2 P300 SERIES FEATURES As this handbook covers the full feature set of the P300 Modem, some of the text will not be applicable to modems equipped with only a subset of the possibly functionality. In the text where it describes features which are optional it uses phrases like: Requires Drop/Insert feature (standard on P300 IBS and above) Throughout the text the description of the feature (“Drop/Insert”) is consistent, and wherever it is referenced it also states which of the four standard confi

3 DESCRIPTION 3.1 OPERATION The P300 Series modem are fully software controlled and with the exception of the optional G.703 interface option there are no links or switches used to configure the unit. This enables all control and configuration to be performed either locally from the front panel, or by remote M&C. Local control is by front panel keyboard, and a large, easy to read, 80 character LCD display, with clear, intuitive menus for configuration and control. All the set-up parameters are s

Rx IF input This connector is a BNC female and can be used as either a 50 S or 75 S input. The allowable signal level of the desired carrier at the input of the modem is from -60dBm to -30dBm (P310: -70dBm to -20dBm). A level of -45dBm is recommended. The maximum composite power level that should be applied to this port is 30dB above the desired carrier, up to a maximum of 0dBm (P310: Composite +35dBc to max of - 10dBm).
