RFL 9508 Analog Single Side Band Power Line Carrier System

The RFL 9508 offers a choice of two power output levels, and a wide range of options which include the choice of PLC, E1 or T1. Plug-in teleprotection modules are available to complete an integrated communication system design. All channels are capable of Drop and Insert operation at the analog or digital T1/E1 level. These features make for a unique product that is ultimately flexible. The frequency range is 20 kHz to 500 kHz. Single Side Band (SSB) modulation is used for the RFL 9508 where the use of the spectrum is optimized with high quality adjacent channel selectivity. Idle channel noise, cross-talk and spurious outputs are minimized and high frequency stability over the specified temperature range is achieved. The equipment is designed to operate in the harsh environment of electric utility substations and is based, in part, on the successful and proven RFL IMUX 2000 T1/E1 multiplexer family of products.An integrated orderwire service channel is included in the standard system. It features an adjustable volume control and audible ARD tone at the far end when the handset is taken off the hook at the near end.
