The Model 9505 V3 Power Line Carrier System from BPL Telecom is a fully integrated, voice / data switching system capable of supporting the most demanding networking communication environments between electricity board substations. The power and flexibility of the Model 9505 system’s proven architecture has earned BPL Telecom a loyal following among state electricity boards and EPC contractor’s throughout the country.
This latest IC version system provides single or multiplexed voice grade channels for transmitting speech or audio tones over high – voltage transmission lines and insulated static lines. The transmitted audio tones can be used for tele – metering, supervisory control, protective relaying, data and for other purposes.
This is a single-side-band (SSB) carrier system that uses the available frequency spectrum more efficiently than all other modulation techniques. Each terminal is available as either a single or twin channel unit. Each channel provides a voice – grade circuit over the transmission medium.
The equipment can be configured for “speech-plus” operation (simultaneous transmission of speech and audio tones). When used for data only, each channel can carry up to twenty – four 50 – baud telegraphic / data channels. Elements of the system may also be used for cable transmission, open-wire lines, and radio multiplex applications.
The equipment uses DSP techniques for speech, pilot and data band selection. Due to this, the utility has the flexibility of using the entire speech band for different applications.
The operating carrier frequency band of 40 – 500 kHz is available in a single filter, which is an added advantage to the power utility.
The product has amplifier ratings of 40 Watt and 80 Watts.
The product is type tested in line with IEC 495 recommendations.
