Cisco Compact EGC Amplifier Model 93251


The Compact Electronic Gain Control (EGC) Amplifier Model 93251 combines powerful performance with ease of use to meet the growing demands from operators for advanced products. It provides advanced features and benefits to help operators reduce operating costs by streamlining amplifier deployment and configuration and is especially well suited for network upgrades due to increased reverse gain.

The amplifier performs to 1 GHz in the forward path and can be configured electronically, using a handheld programmer terminal, for rapid initial set-up or for adjustments that arise as network requirements shift. All settings are done without interrupting service, an especially important capability in networks which are delivering Voice over IP (VoIP) services.

Settings for the EGC amplifier can be established or modified using a handheld programmer terminal. Settings from one amplifier can be uploaded to the handheld programmer terminal for downloading to other amplifiers in order to streamline their configuration. Different forward gain settingscan be obtained in the amplifier, enabling it to support several different applications within the network allowing a single amplifier model to help reduce inventory and lower costs.

The number of amplifier plug-ins is reduced to a minimum to help operators keep inventory and costs down. The full range electronic attenuators and equalizers offer improved versatility and make it possible to achieve the same adjustment range as with conventional plug-in or potentiometer solutions. Plug-in diplex filters are used to determine the forward/reverse band split. To meet future demands for more bandwidth, the amplifier offers an electronic 862 MHz to 1 GHz field-programmable bandwidth extension, as well as a reverse path that can be upgraded to 200 MHz. The Compact EGC Amplifier Model 93251 can be configured with a Scientific Atlanta status monitoring transponder (SMC or HMS) to enable remote monitoring ofcritical amplifier parameters and remote control of the built-in 3-state reverse switch. All amplifier settings are remotely addressable via the ROSATM Element Management System to help reduce truck rolls and associated costs.
