Introduction
The Harmonic Electra™ 1000 Multichannel Encoder provides multichannel standard
definition MPEG-2 encoding and DiviTrackIP™ statistical multiplexing. It accepts up to four
analog composite or serial digital standard definition video inputs, and up to ten analog or
digital audio inputs. The encoder operates within an IP environment, allowing flexible network
architectures.

2.1 Operating Environment
The encoder operates under the control of NMX™ Digital Service Manager. NMX manages
multiple Electra 1000 encoders and other devices. NMX provides full configuration of the
Electra 1000 platform, ports, services, and PSI, as well as alarm management. You configure
a few initial network settings from the front panel of the encoder. The encoder operates within
an IP environment; therefore, encoders and multiplexers do not need to be in the same
physical location. Harmonic recommends discussing your planned network architecture with
a Harmonic representative before implementation.
